Wishlist for future features

-> see bottom of this document

MIDIboxSEQ V4.091

   o new parameter type "Chord2" provides an alternative set of 32 chords

   o CPU load display has been re-adjusted for LPC17 and STM32F4

   o hwcfg/wilba*/MBSEQ_HW.V4: default F1-F4 assignments changed to:
     F1: Bookmark, F2: Record, F3: Tap Tempo, F4: Save All

   o MBSEQ_HW.V4: added new button/LED functions: FX, MOVE, SCROLL

   o MBSEQ_HW.V4: added new LED_MEASURE function which will activate a LED
     when the first step of the measure is played.

   o CC Parameter layer label now prints "#<number>" instead of "CC"

   o Jam page: AStart now starts to record into first step in 
     live recording mode (as intended), it starts on the selected step
     in step recording mode

   o Purpose of Record and Live Button & LED change:
     they switch between record (and live) mode w/o changing to the Jam page

   o new button/LED combo: JAM_LIVE and JAM_STEP: they switch to the JAM
     page and select Live resp. Step recording mode

   o New option page item #10 "Initial Gate Trigger Layer" 
     (empty or trigger on each 4th step)

   o removed obsolete (non-working) pattern based scale control

MIDIboxSEQ V4.090

   o Fx->Scale page: the configured scale is now displayed at the right
     half of the page

   o Track duplication now also possible with COPY+PASTE in UTILITY page

   o Track selections (Parameter/Trigger Layer, instrument, step view)
     can now be handled individually for each track.
     This function can be enabled in the UTILITY->Opt menu (item #9/16)

   o added BLM fader configuration to UTILITY->Opt menu (item #14/16)
     Up to 8 faders can be connected to the BLM16x16+X
     They can send a CC value either to a statically assigned Port/Chn, or to
     the Port/Chn defined by the track.

     Optionally value can be sent with inverted polarity (turn encoder beyond CC#127).

     Additional (internal) functions can be added in future.

   o BLM in keyboard mode: transpose only takes place if track not in normal
     (no transpose) mode!

   o if a track plays a sustained note, and doesn't play a step anymore
     (all gates cleared), the sustain will be cancled now

   o improved Auto Start in Jam page

   o Jam recording options are now stored/restored in/from session 
     configuration file

   o SONG button has now the same function like the SELECT button: it shows
     a configuration page. This makes it more consistent to the EDIT button.
     In future, the SELECT button might get a new function in SONG page.

   o Song mode: if Steps per Measure < Steps for Pattern synchronisation, the
     song sequencer will already switch to the next pattern with the next measure.

MIDIboxSEQ V4.089

   o added DIN testmode which can be enabled from the MIOS terminal with the
     "set din_testmode on" command to display button and encoder movements.

   o added "Roll Gate" as new optional trigger layer assignment.
     It gates the Roll or Roll2 value which is configured in a parameter layer.

   o Euclid Generator: parameter layer into which the pattern will be copied
     now selectable.
     Velocity/Accent will only be changed if the first parameter layer is selected.

   o it's now possible to quickly duplicate the steps of a track:
     press&hold COPY and press the PASTE button

   o Groove page: by default, groove configuration changes are applied on all tracks now.
     It's possible to select a "local groove" by pressing GP7 button in the groove page.

   o BPM page: it's now possible to configure an output delay for each MIDI port.
     (positive and negative delays are supported - this is currently an experimental feature!)

   o fixed NoteOff in Jam Forwarding mode if FTS, Limit or Humanizer is enabled

   o NOTE: due to a RAM capacity issue, the UNDO function is currently not available
     for the LPC17 firmware

MIDIboxSEQ V4.088

   o improved glide function for polyphonic steps

   o BLM16x16+X support for Mute and Solo
     The new functions are available at Extra Row Button #3 and #4
     (if a BLM16x8+X is connected, they replace Start/Stop at Extra Row Button #1 and #2)

     If Mute active: the extra column buttons mute/unmute tracks
     If Solo active: the extra column buttons solo/unsolo tracks

     LED Colour coding:
     - LED off: Track neither muted nor soloed
     - LED green: Track muted
     - LED yellow: Track soloed
     - LED red: Track muted and soloed - solo has higher priority, therefore track will be played

     Special Key combinations:
     - ALT+Mute clears all mutes
     - ALT+Solo clears all solos

   o added Robotizer Fx from Borfo

   o added LCD Screensaver.
     It will be active after 30 minutes by default.
     The time can be changed in the UTIL->OPT menu page.

   o added DETENTED4/DETENTED5 option for rotary encoders in MBSEQ_HW.V4 file

   o added new parameter layers "Nth1" and "Nth2" which trigger a special action 
     on each nth bar (Nth1) starting at the 1st bar, or after nth bars (Nth2).
     Following trigger conditions are available:
     - Pl (Play each nth bar)
     - Mu (Mute each nth bar)
     - Ac (Accent each nth bar)
     - Ro (Roll each nth bar)
     - Fx (enable Fx each nth bar)
     - Nx (don't enable Fx each nth bar)

   o combined Record and Live page to a new single "Jam" page with sub pages 
     to improve the overview and simplify the configuration.

   o added Live Pattern Recording to Jam page which can be used to play and record
     customizable arpeggiator sequences.
     Available in the Jam page (Utility->Jam->Ptn)
     See updated user manual for further information.

MIDIboxSEQ V4.087

   o new page: "Track Instrument"
     Can be selected with MENU->EVNT->Trk Inst (GP #8) or from the main page (after Track Event item)
     Allows to configure the MIDI port, channel and instrument name.

   o the new Track Instrument page also allows to select Program Change and Bank (Low/High byte)
     If activated, these parameters will be sent when the sequencer is started and on pattern changes.
     Please note: a program and bank change can stall your synth so that the first note could be delayed!
     Use this function only when the device can handle patch changes quickly!

   o added CV_GATE_SR1 and CLK_SR to MBSEQ_HW.V4 config
     This is the prefered option to add CV gates and DIN clock/start signals to your MIDIbox SEQ in future.
     See also updated

   o 8 individual DIN Sync clock outputs with individual divider and pulsewidth values are
     provided now. A clock output can optionally be turned to a Start/Stop output.
     The outputs are available at the configured CLK_SR DOUT shift register pin D7..D0
     (D7=first output, D6=second output, etc...)
     The clock parameters can be configured in the CV configuration page.

   o Mixer page: channel events can be dumped by pressing the corresponding GP button.
     This also allows to prepare different mixer setups, sending to the same channel, triggered
     by a GP button

   o Mixer page: press SELECT to activate/deactivate "live sending" mode (values are sent
     while moving an encoder)

   o Mute page: the synchronized mute/unmute option can be temporary overruled by activating
     the FAST button function

   o improved step recording display for drum tracks

   o Selected Datawheel mode in edit page now stored/restored to/from SD Card

   o STM32F4: support for bootloader "enforce_usb_device" flag

MIDIboxSEQ V4.086

   o various improvements for external BLMs with different dimensions
     (previously only BLM16x16+X was properly supported)

   o corrected behaviour of ALL button in EDIT page (GP buttons change
     selection pattern with GP buttons)

MIDIboxSEQ V4.086

   o MIDI Learn for Drum notes in Track Event configuration page:
     on a drum track, press & hold button GP12 to set the drum note
     depending on the configured recording port & channel (which has to be
     configured in the RECORD page)

   o Edit page: press&hold a GP button to record directly into the selected step

   o Edit page: config page which was previously visible by pressing the SELECT
     button now displayed by pressing&holding EDIT button.
     SELECT button now toggles step recording mode

   o Edit page: added shortcut to Recording Config (EDIT+GP11/GP12)

   o Record page now allows to toggle the FTS and FX flag for MIDI Forwarding
     (same flags can be configured in LIVE page)

   o Step Recording: note length measurements now also working correctly when
     the sequencer is clocked in slave mode.

   o Track Event configuration page: VelN/VelA not displayed if they are
     not relevant for the selected configuration.

   o Clear function will clear all selected tracks

   o LFO page: Extra CC can now be disabled/enable with a separate switch

   o Echo page: echo can now be enabled/disabled without touching the repeat value

MIDIboxSEQ V4.085

   o it's now possible to customize the MENU short cut page in MBSEQ_HW.V4
     with the new MENU_SHORTCUT parameter.
     See the templates under hwcfg/*/MBSEQ_HW.V4 for further informations.

   o the bookmark configuration files (MBSEQ_BM.V4) are using the same
     page names like MENU_SHORTCUT instead of numbers.
     The old number scheme will be automatically converted to the new names.

   o improved keypad (SMS-like) entry of names

   o SysEx device page allows to specify a delay between SysEx messages which is
     used when a .syx file contains multiple dumps

   o each SysEx device page has now a dedicated port/delay configuration which
     is stored/restored from the /SYSEX/<device>/DEVCFG.V4 file

MIDIboxSEQ V4.084

   o the STM32F4 variant of the firmware supports USB Host mode!
     See also

   o If Force-to-Scale is enabled, the edit screen shows the forced keys at the lower line.
     The original value is still displayed at the upper right line.

   o Live Page: FTS (Force-To-Scale) not applied on drum tracks anymore

   o Options Page: added new option which enforces Force-To-Scale for
     BLM16x16+X Grid Edit mode

   o Euclid Generator Page: velocities are re-generated automatically whenever
     VelN or VelA value is changed

   o the optional RECORD button now toggles between RECORD and EDIT page (previously it
     only switched to the RECORD page)

   o Song page: new action "Unmute all" will unmute all tracks and parameter layers

   o Mixer: in the UTIL->Options page it's now possible to define if CC1, CC2, CC3, CC4
     should be sent after or before the Program Change event.

   o NRPN MSB=127 allows to modify parameters of the currently selected track

MIDIboxSEQ V4.083

   o fixed potential hang-up during pattern change which was introduced with V4.081

MIDIboxSEQ V4.082

   o Options in LIVE page are now stored in session specific MBSEQ_C.V4 file

   o initial release for MBHP_CORE_STM32F4

MIDIboxSEQ V4.081

   o added USB MIDI workaround for Windows

   o fixed synchronisation issue in Song mode

MIDIboxSEQ V4.080

   o SELECT+PASTE transfers the parameter layer, which was active during COPY, to
     the current parameter layer.
     If a drum track is selected, it's doing this for the trigger layer (and not
     for the parameter layer).

   o SELECT+CLEAR clears only the current parameter layer.
     If a drum track is selected, it's doing this for the trigger layer (and not
     for the parameter layer)

   o it's now possible to control the track steps with CCs.
     Each track has a dedicated CC which has to be configured in the
     MIDI->Ext.Ctrl page.

   o it's now possible to turn off the track clock by enabling the new "Manual"
     mode in the DIVIDER page. Once enabled, a step will only be played if:
     - manually triggered in the MANUAL page
     - set with the new CC based step control feature (MIDI->Ext.Ctrl page)

     Use cases:
     - predefined MIDI events, stored in the track layers, should be manually
       triggered (and not sequenced).
       E.g. in conjunction with a sampler, you could set each step to a note
       which "fires" a certain sample. In addition, you can fire CCs,
       Program Change, Aftertouch etc. from the MANUAL page.

     - the track should be controlled from an analog modulation source (e.g. a
       sawwave from a LFO). MIDIbox SEQ doesn't provide analog inputs, so that
       an external CV-to-MIDI interface is required.
       Note that this interface also has to scale the CC value over the desired
       step range. If the modulation source should sweep over step 1..16, then
       the CV-to-MIDI interface has to scale down the converted value to the
       CC value range 0..15!

MIDIboxSEQ V4.079

   o added new Fx which allows to send to one or more additional MIDI channels
     from a single track with various behaviours (forward to all, alternate
     between channels, randomly select channel)
     The new functions can be configured at the Fx->Dupl (like Duplicate) page

   o groove page: added possibility to change the intensity for all tracks at once

   o MBSEQ_HW.V4 file: SR numbers for BUTTON and LED functions which are
     assigned to the BLM8x8 matrix (-> Wilba's Frontpanel) are now named M1..M8
     instead of 17..24
     See also the configuration template under hwcfg/wilba/MBSEQ_HW.V4
     The old syntax is still provided to keep old MBSEQ_HW.V4 files compatible.
     Once the new SRIO_NUM_SR parameter is set to 17 or more SRs, the new syntax
     has to be used.

   o MBSEQ_HW.V4 file: new parameter SRIO_NUM_SR allows to specify the maximum
     number of DIN/DOUT shift registers in a chain. Up to 23 DINs/DOUTs can be
     chained now - this is also the new default value in the MBSEQ_HW.V4 templates.

   o whenever a MBSEQ_HW.V4 file is uploaded with the MIOS Filebrowser, the
     configuration will be automatically reloaded (no need to reset the core)

   o official support for Ilmenator's Track Position Display.
     See also
     An example configuration (TPD directly connected to J2 of Wilba's Frontpanel PCB)
     can be found under hwcfg/wilba_tpd/MBSEQ_HW.V4

   o the TPD display mode can now be configured in the Utility->Options menu (item #11)

   o added new MIOS Terminal commands:
     new, saveas, save, load, delete, session, sessions

MIDIboxSEQ V4.078

   o removed MSD (mass storage device) mode to save some memory.
     With the MIOS Filebrowser (integrated into MIOS Studio) this mode has a good
     replacement meanwhile. For direct access to the SD Card another application (like
     MIDIO128) could be temporary uploaded... or the SD Card can be plugged into
     a common SD Card reader.

   o Options page has been overworked, so that more options can be added in future

   o experimental: if Live mode or a MIDI Router based "Track" or "Sel.Trk" is active,
     and Note, CC, PitchBender, Program Change is received on the selected IN Port,
     the corresponding track layer (or LFO CC) will be muted completely, or temporary for
     a given number of steps.
     This allows to temporary overrule events generated by the sequencer from
     an external MIDI keyboard or controller.
     This feature has to be configured in the UTILITY->Options page, it's disabled by default!

   o activate the ALL function (press ALL button) in the mute page to get a new 
     menu page which allows to mute/unmute all tracks, layers of current track or 
     mute&layers of all tracks.
     Sidenote: this obsoletes the UTILITY->MUTE and UNMUTE function, which might
     be replaced by something else in future.

   o the 6 new mute/unmute functions are now also accessible from dedicated buttons
     (and LEDs). They have to be assigned in the MBSEQ_HW.V4 file.

   o it's now possible to control the track mutes via CCs.
     The first CC (for the first track) has to be configured in the MENU->MIDI->Ext.Ctrl
     page. The remaining tracks are controlled from the 15 consecutive CCs.
     E.g. if the CC number is set to 16, the mutes of track 1-16 are controlled with
     CC#16 .. CC#31

   o it's now possible to dump a mixer map via CC. The CC has to be configured in the 
     MENU->MIDI->Ext.Ctrl page.

   o a CC assigned to a sequencer layer won't be sent if it's also assigned to
     the LFO "Extra CC"

   o if a track is initialized, CC layers will be assigned to "off" by default
     (no CC will be sent). The desired CC number has to be set explicitly before a
     CC layer will send an event.

   o in record mode, incoming CC events will be automatically assigned to free CC 
     layers so that no pre-configuration is required (like known from MBSEQ V4L).
     A CC layer is "free" (unassigned) as long as the CC number is turned "off". This
     is the default setting for all CC layers after initialisation, and can be changed
     in the MENU->EVENT page if desired.

   o Trigger/Layer/303 edit view working again

MIDIboxSEQ V4.077

   o it's now possible to send parameter changes, done from the user interface,
     to a specified MIDI output port. This allows to record such changes with a DAW.
     The output port has to be selected in the MIDI->Ext.Ctrl page, where also the
     input port and channel is specified.

   o a very useful "quick save" function has been added which significantly improves
     the song phrases handling.

     The new function will store the current mixer and pattern setup into predefined
     bank positions:
       - Phrase A will use Mixer Map #1 and Patterns 1:A1 2:A1 3:A1 4:A1
       - Phrase B will use Mixer Map #2 and Patterns 1:A2 2:A2 3:A2 4:A2
       - Phrase C will use Mixer Map #3 and Patterns 1:A3 2:A3 3:A3 4:A3
       - ...
       - Phrase P will use Mixer Map #16 and Patterns 1:B8 2:B8 3:B8 4:B8

     After the store operation, following references will be copied into the phrase
     slot of the song:
       - 1st phrase step: the current mutes
       - 2nd phrase step: selects the new mixer map
       - 3rd phrase step: selects the new pattern set
       - 4th phrase step: jumps to the 3rd phrase step (could be useful in song mode)

     How to use this function:
     Start a new session, edit some tracks, start jamming.
     Whenever you've found sequences which play well together, change to the SONG page,
     press&hold the SELECT button, then select "Save&Take over Patterns" with GP button 16.
     Thereafter release the SELECT button, and select the target phrase slot with
     one of the GP buttons -> this will store the current mutes/mixer map/patterns
     into the predefined bank positions and insert references into the phrase slot.

     Now you can continue jamming, change tracks, change mixer values, change mutes.
     Whenever you found a new nice working sequence, go to the SONG page and store
     it into another phrase slot (or overwrite an existing slot).

     The stored phrases can be restored as usual with the GP buttons in the song page.

   o it's now possible to specify the initial CC value (for the CLEAR and INIT
     function) in the UTILITY->Options page

   o LFO: CC layer modulation is working properly again

   o Mixer Map not switched on pattern changes anymore (this is actually only
     part of the "Remix" feature).
     To get the Remix function properly working again, please open your 
     MBSEQ_GC.V4 file with the MIOS Filebrowser, search for "PatternMixerMapCoupling" 
     and set it to 1.
     If this parameter doesn't exist yet, please create it:
     PatternMixerMapCoupling 1


MIDIboxSEQ V4.076

   o the MIDI router forwards SysEx messages regardless if channels are filtered,
     or "All" is used. It's ensured that messages are only sent once if multiple
     router nodes forward to the same destination port.

   o added optional "SAVE" and "SAVE_ALL" button function to the MBSEQ_HW.V4 file

   o it's now possible to change the mixer map name.
     In the mixer page, press SELECT + GP16 button to enter the name editor.

   o LFO page: the current CC can be sent manually by pressing the GP14 button.

   o Multi-Arp events are working like intended (again)

MIDIboxSEQ V4.075

   o MBHP_IIC_MIDI working properly again on a STM32 core (issue was caused by a compiler change)

   o Track event configuration page: if a parameter layer is configured for CC,
     Pitchbender or Program Change, it's now possible to send the event manually
     by pressing one of the GP buttons below the controller configuration (GP10, 11, 12, 13)

   o MIDI remote keyboard function now also deactivated when Note On with velocity 0 received

MIDIboxSEQ V4.074

   o "SD Card connected" message not displayed after boot anymore, instead only 
     when the SD Card is exchanged

   o whenever the ALL function is active, you can now directly select the steps
     which should be modified with the GP buttons (LEDs will show the selection pattern)

   o the ALL function has been enhanced:
     - press & hold the ALL button and move the encoder of the already selected step
       (marked with >...<) to change all steps to the same value (like before)

     - if ALL button not pushed (but active), move the encoder of the already selected step
       (marked with >...<) to change all step values relatively (like before)

     - NEW: if ALL button is active (regardless if pushed or not), and the encoder
       of an unselected step is moved, the editor will generate a ramp between the
       selected step and the moved encoder.
       This feature has been borrowed from Sequentix Cirklon - thanks for the inspiration! :-)

     The "selected step" can either be changed with the datawheel, or it will be
     changed if the ALL function isn't active (as before)

MIDIboxSEQ V4.073

   o bugfix for "single_usb" option

   o the MIDI router provides the new destination "Sel.Trk"

     Usecase: MIDI events, such as CC or Notes, should be sent from a master keyboard
     or MIDI controller to the MIDI port and channel of the currently selected track.

MIDIboxSEQ V4.072

   o support for the "single_usb" option, which can be enabled with the
     bootloader update application V1.012 ("set usb_single 1")

     Use this option if you are working with a Windows PC which can't handle
     the 4 USB ports correctly (e.g. stucking MIDI, Filebrowser operations are failing, etc.)

MIDIboxSEQ V4.071

   o if not in song mode, the Rew/Fwd buttons can now be used to select the step view.

   o the MIDI router provides the new destination "Track".

     If this destination is selected, incoming MIDI events will be routed to the
     MIDI port and channel of a track depending on the incoming MIDI channel number.

     Usecase: MIDI events, such as CC or Notes, should be sent from a master keyboard
     or MIDI controller to synths which are assigned to different port and MIDI channels
     in the track configuration.
     Just select the track with the MIDI channel on your keyboard/controller, the router
     will take care that the events reach the right destination.

   o it's now possible to send a CC when a track has been selected.
     This feature allows to synchronize the track selection with a DAW.
     It has to be configured in the MBSEQ_HW.V4 file (search for TRACK_CC in hwcfg/*/MBSEQ_HW.V4)

MIDIboxSEQ V4.070

   o LPC17: robustness of LCD driver has been improved

   o the MIDI configuration page got a new subpage called "Ext.Ctrl"
     This subpage allows to assign CCs to functions like Morph Value,
     Scale, Song, Phrase, Patterns, Banks, All Note Off, etc.
     Some of these functions can also be assigned to a Program Change Event.
     The MIDI port and channel over which these functions are accessible is free assignable.
     The MIDI channel is disabled by default, which means that the Ext Ctrl. feature
     has to be explicitly enabled in the MIDI->Ext Ctrl. page!!

   o improved transpose handling if loopback track is running with sustain enabled,
     or with notes > step length (glide)

   o note stack now automatically cleared if transpose was controlled by a loopback
     track, and then manually from an external keyboard.

   o it's now possible to transpose with chords (or multiple notes) from a loopback

   o the "sdcard_format" command allows to format the connected SD Card with FAT32
     from the MIOS Terminal

   o added BLM_GP_ALWAYS_SELECT_MENU_PAGE option to MBSEQ_V4.HW file

MIDIboxSEQ V4.069

   o USB MSD driver: changed endpoint to avoid conflict with MIDI driver.
     Note that it's still not possible to use MSD and MIDI in parallel,
     but Windows and MacOS should accept the connection (again).

   o Event configuration page: the selected layer type now has to be confirmed with 
     GP button below the appr. item.
     A warning message will pop up to notify about this unusual data entry method.
     In addition, the value will be marked with '!' as long as it doesn't match with
     currently active value.

    o it's now possible to delete a session from the main page

MIDIboxSEQ V4.068

   o support for GM5 driver under Windows.
     MacOS and Linux users: just install this update, no additional changes required.
     Windows users:
     - upload the application with MIOS Studio
     - close MIOS Studio
     - install the GM5 driver which can be downloaded from
     - start MIOS Studio -> 4 "GM5" USB ports should be visible

MIDIboxSEQ V4.067

   o USB device settings have been changed.
     IMPORTANT: please install MIOS32 Bootloader V1.010 before uploading
     the application! Otherwise code upload via USB won't work anymore!
     (Backup: upload via MIDI IN1/OUT1)

   o support for MIOS Filebrowser, which will be part of MIOS Studio 2.4

MIDIboxSEQ V4.066

   o fixed potential stack overflow in LPC17 build

MIDIboxSEQ V4.065

   o the DEBOUNCE_DELAY parameter of the MBSEQ_HW.V4 file will now be also taken
     for the BLM8X8 (Wilba's Frontpanel)

   o Mixer: setup now automatically loaded when a new mixer map is selected

   o Sessions: the SAVE function now also stores the current mixer map

MIDIboxSEQ V4.064

   o corrected tap tempo function

MIDIboxSEQ V4.063

   o The "Guide Track" now synchronizes tracks and pattern changes independent
     from the "steps per measure" option

   o it's now possible to change or disable a guide track from a song position entry

   o the "RATOPC" (restart all tracks on pattern change) option now resets the track
     synchronously with the next step

   o the clear button now clears the track immediately (2 second delay has been
     removed). Please discuss in the MIDIbox forum if you don't like this change.

   o the copy/paste/undo functions now also copy the track and drum instrument names

MIDIboxSEQ V4.062

   o fixed potential hard fault when storing preset pattern

MIDIboxSEQ V4.061

   o STM32: MBHP_ETH module working properly again

MIDIboxSEQ V4.060

   o fixed initialisation of MBHP_AOUT module

   o Song Mode now provides a "Guide Track" which can be configured
     by pressing SELECT in SONG page: the length of this track defines
     the loop length and once the last loop has been played, all tracks
     will be synchronized to step 1.
     This allows to program breaks with a step length which is independent
     from the measure.

   o Phrase Mode now syncs the pattern changes to the measure of SyncChange
     is set in the UTIL->OPT page

   o Phrase Mode manually triggers the "synch-to-measure" option for all tracks
     to ensure that all tracks are re-synchronized to step 1

   o MBSEQ_HW.V4 files: changed encoder mode to MIOS_ENC_MODE_DETENTED3
     since it's compatible with most encoders

MIDIboxSEQ V4.059

   o added Euclidean Rhythm Generator for drum and synth sequences.
     The page can be entered by pressing&holding SELECT in the edit menu -> GP16

   o fixed stack overflow which happened when incoming OSC messages were forwarded
     to OSC in Live mode (they are now automatically filtered to avoid feedback loops)

   o fixed group selection in BUTTON_DIRECT_TRACK1...16

MIDIboxSEQ V4.058

   o a new Pattern Remix feature has been implemented by Midilab.

     It's optimized for live sessions and got a special page:
        - pattern names can be previewed before they are selected
        - patterns change when the selection button is pressed a second time
        - mixer maps are dumped with pattern change
        - the "Remix" function allows to select tracks which should be kept
          (not overwritten by pattern changes)
        - allows to synchronize with Ableton Live clips

     The full documentation can be found under:

     Note that the correct function of this feature requires, that the remix page
     is assigned to a dedicated button. This has to be done in the MBSEQ_HW.V4 file
     (new entry: BUTTON_PATTERN_RMX) - e.g. you could assign it to F4

   o corrected SysEx output for LPC17

MIDIboxSEQ V4.057

   o improved MIDI OUT throughput for LPC17

MIDIboxSEQ V4.056

   o pattern page: the ALL button now allows to change all patterns 
     to the same number at once (banks won't be influenced by ALL button).
   o the ALL function will always be turned off when changing to another page.
   o song page: the previously "Stop" action has been renamed to "End" - it doesn't
     stop the sequencer anymore, instead it only exits song mode and loops the
     current pattern set endless (e.g. to fade out or as bridge before you select
     the next song).
   o song page: press SELECT+GP16 to take over the current pattern set into the
     selected song position - this function can be used for quick song/phrase edits.
   o song page: in song mode it's now possible to select a phrase with GP buttons
     (like in Phrase mode).
     Difference: the song positions will be played until they are looping or "End"
     is reached. This allows to split a song into multiple parts which are 
     interactively selected.

   o song page: Fwd/Rwd button change also the edit position in song page
   o if the sequencer is started in song page, the song will directly jump to the
     current edit position

   o the main page now displays the effective BPM. If in slave mode, the received
     BPM will be displayed.
   o the BPM digit display shows the received BPM in slave mode.
   o new layer type: program change

MIDIboxSEQ V4.055

   o LPC17 build: optimized MIDI IN handling

   o LPC17 build: MIDI clock can now be received over MIDI IN1..4

   o SysEx forwarding via MIDI router working (again)

   o MIDI router supports 16 nodes now! (previously only 8)

   o fixed bug in PitchBender Editing mode

   o added new MIOS terminal commands:
     - display network informations, modify network and OSC settings
     - display MIDI router informations, modify MIDI router settings
     - change BLM port remotely
     - "store" and "restore" the session remotely

   o BLM now supports Lemur on iPad
     Example configuration (we assume that iPad IP address is
     - set osc_remote 3
     - set osc_local_port 3 8000
     - set osc_remote_port 3 8000
     - set osc_mode 3 1
     - set blm_port OSC3
     - store
     (the commands can be entered in MIOS terminal).
     On your iPad, set the IP address of your MIDIbox with port 8000

   o BLM now allows to record MIDI notes in the keyboard page

MIDIboxSEQ V4.054

   o in edit page the datawheel can now be used for different purposes:
     it can scroll the cursor, the step view, can change the value (as before)
     and it can be used to select the parameter/trigger layer.
     The function can be selected by pressing SELECT + GP7/8

   o Rômulo aka. Midilab started to implement a footswitch function which
     is especially useful for live recording and track modifications while
     playing on a keyboard.
     Press&Hold the footswitch to enable record mode, release it to disable
     record mode.
     Tap the footswitch shortly to delete the track.
     The footswitch can be assigned to a free DIN pin in MBSEQ_HW.V4

   o note and chords can now be edited without immediate change by pressing&holding
     the EDIT button. The new value will be taken over once another step is
     edited, or the EDIT button is released.

   o fixed potential buffer overrun when preset is stored

MIDIboxSEQ V4.053

   o bugfix: MIDI IN ports are working again on MBHP_CORE_STM32 build

MIDIboxSEQ V4.052

   o bugfix: CC values were influenced when they were displayed on the edit page

   o Hawkeye fixed the BPM/STEP digits output and added a "TPD" (track position
     display) option for those who like to add more blink to their MIDIbox!

MIDIboxSEQ V4.051

   o improved live-recording of CCs

   o warning is print on screen if poly recording selected on a track with
     only one (or none) note layer

   o Drum live/step recording: disabled mapping of drum instruments
     to keys C/C#/D/D#/... - it was too confusing.

   o BPM LED Digit function: added optional 4th digit to display the value after the dot

   o added optional LED digits to display the played step.
     Anodes require a dedicated Shift Register, the 3 cathode lines can be shared with
     the shift register which is used to drive the cathodes of the BPM LED Digits.

   o added optional BPM (Tempo) encoder.
     As usual the pinning can be configured in the MBSEQ_HW.V4 file

MIDIboxSEQ V4.050

   o added LED functions for received MIDI IN/OUT events to MBSEQ_HW.V4

   o added BPM LED Digit function to MBSEQ_HW.V4
     A schematic can be found under

   o SR1 working again (programming error during MBSEQV4L merge)

MIDIboxSEQ V4.049

   o support for MIDI OUT4 and MIDI IN4
     Provided by MBHP_CORE_LPC17 module only.
     MIDI OUT4 is available at J4B.SD
     MIDI IN4 is available at J4B.SC

   o fixed USB issue under Win7 if the interface name hasn't been
     customized in bootloader

MIDIboxSEQ V4.048

   o CC and PitchBender values only send on value changes anymore to save
     MIDI bandwith on high-speed tracks

   o Step record: simplified usage of poly mode. Now the step is automatically
     cleared when all keys were released and new notes are entered.

   o Step record: duration (note length) will now be recorded as well!

   o Live record: some improvements for the "forward MIDI" option

   o MSD mode (SD Card Reader) can now also be enabled with the "msd" command
     in MIOS Terminal

   o Move step: doesn't overwrite new selection anymore

MIDIboxSEQ V4.047

   o MIDIbox SEQ V4 is not beta anymore - but we continue to increment the
     version number and just leave out "beta" :-)

   o compiled for new MIOS32 Bootloader V1.005
     You can safely enable the "fastboot" option of the bootloader, so that
     the application starts immediately after power-on

   o for MBHP_CORE_LPC17: since this board doesn't provide a J5C connector,
     following signals are available at J28:
     - Clock: J28.SDA
     - Start/Stop: J28.SC
     - Gate 7: J28.WS
     - Gate 8: J28.MCLK

   o OSC Client/Server: support for TouchOSC protocol

MIDIboxSEQ V4.0beta46

   o added multi copy function: press MENU+COPY to export all selected tracks
     into the /PRESETS folder on SD Card. The resulting files are named
     COPY[track].V4T (the [track] numbers are independent from the actual track

   o added multi paste function: press MENU+PASTE to import "COPY[track].V4T"
     files from the /PRESETS folder into all selected tracks, starting from
     COPY1.V4T to (up to) COPY16.V4T

   o use these new functions to quickly copy&paste tracks between patterns
     and sessions, to create temporary backups, to duplicate tracks, or whatever.

     Note that you can also import these COPY[track].V4T files from the
     MENU->Event->PRESETS menu, e.g. to exclude certain parts of the preset

   o buttons of Wilba's Frontpanel are now debounced

MIDIboxSEQ V4.0beta45

   o USB update for MacOS 10.7 Lion

   o Chords displayed correctly when a velocity layer is edited

MIDIboxSEQ V4.0beta44

   o session can be selected again

MIDIboxSEQ V4.0beta43

   o delayed mute/unmute which is synched to the measure.
     It can be enabled individually in the global options menu (UTILITY->OPT)

   o trigger assignment page: trigger layer of the current assignment automatically
     selected (alternative way to select a trigger layer)

   o random page: random values can now be generated for all parameter and trigger
     layers (resp. drums: parameter and drum instruments).
     The selection is scrollable with a GP encoder.

   o random page: special behaviour for drum tracks: parameter layers and each
     individual drum instrument can be randomized (no triggers in this mode
     to keep the code simple)

   o random page: new values will only be generated when "Generate" button is
     pressed, or for a single layer if the GP button under the appr. layer is

MIDIboxSEQ V4.0beta42

   o Handling of Start/Stop/Pause button changed for Slave and Auto Mode to allow 
     proper synchronisation to the measure when multiple sequencers are playing

     Whenever a MIDI clock is received:
     - the STOP button won't stop the sequencer, but just disables the output of
       all tracks (like a Mute). The step progression continues to run.
     - the START button won't start the sequencer immediately.
       Instead MBSEQ will wait for the next measure and then enable track output again.
     - the PAUSE button will enable/disable track output, but the track progression
       continues to run.

     In order to notify that track outputs are disabled, the START/STOP/PAUSE
     LED flashes to the beat.

   o Added Live page.
     The page can be entered by pressing UTILITY -> Live (GP Button #11)

     Inside this page notes (and drum instruments) can be played with the GP buttons.

     In addition the 4 MIDI IN Busses for Transposer/Arpeggiator/Live Playing can be
     configured like in the MIDI page.

     Following Live Play parameters are available:
     - track selection
     - track mute/unmute
     - Octavewise transpose
     - Velocity (only used for GP button keyboard)
     - FTS (Force-To-Scale)
     - FX on (enables Humanizer, LFO, Limiter and Echo)
       Note: the Echo effect will only work when the sequencer is running!

   o parameter layer mutes are now also working for

   o Echo Fx now also works with "zero delay". In conjunction with the Note incrementer
     and (optionally) force to scale this results into a "poor man's chord" mechanism. ;-)

   o Move function works beyond step 16 as intended again

MIDIboxSEQ V4.0beta41

   o Global/Session bookmarks: the first 8 bookmarks are now stored in the root
     directory, the remaining 8 bookmarks in the session directory

   o hwcfg/wilba/MBSEQ_HW.V4: F1 button now assigned to bookmark page

   o added 16 dedicated bookmark buttons which can be assigned in MBSEQ_HW.V4

   o Manual Trigger Request: now synchronized to next step

   o edit page in drum mode: parameter layer is displayed when parameter
     select button is pressed

   o added "RATOPC" (restart all tracks on pattern change) option to UTIL->Opt menu

MIDIboxSEQ V4.0beta40

   o added bookmark function:
     - Press MENU+SELECT to enter the bookmark page
     - Alternatively this function can be assigned to a dedicated button/LED
     - inside this menu, press a GP button (shortly) to recall a bookmark
     - press&hold a GP button for 3 seconds to store a bookmark

   o the bookmark function stores following UI settings:
     - Bookmark name
     - Current page
     - Group
     - Tracks
     - Mutes
     - Parameter Layer
     - Trigger Layer
     - Instrument
     - Step View
     - Step
     - Edit View
     - Solo/All/Fast/Metronome/Loop/Follow button mode

   o Bookmarks are stored into the MBSEQ_BM.V4 file, which can be edited with
     a common text editor.
     This is the only way to change a bookmark name (5 characters)

   o it's possible to prevent, that a certain UI parameter will be overwritten by a
     bookmark. This can (only) be done by editing the MBSEQ_BM.V4 file:
     Just replace the '+' sign at the beginning of the parameter name by a '-' sign.

MIDIboxSEQ V4.0beta39

   o BUTTON_PAR_LAYER_A working again (was overwritten by BUTTON_DIRECT_TRACK16)

MIDIboxSEQ V4.0beta38

   o CPU load reduced by more than 20%, this especially results into faster SD Card operations!

   o fixed move step function for moves which select the next step view

MIDIboxSEQ V4.0beta37

   o Length Page: quick selection now also available for loops.

   o Length Page: length/loop presets are now stored in MBSEQ_C.V4 file (located
     in session directory) under the name "QuickSelLength", "QuickSelLoopLength" and
     They could be edited with a text editor if you would like to have different values.    

   o track transpose page now always starts with "octave" item instead
     of "semitones" item

   o it's now possible to define 16 individual "direct track selection" buttons
     in MBSEQ_HW.V4 (search for BUTTON_DIRECT_TRACK*)

   o it's now possible to define 2 shift registers for outputing the current track
     selection in MBSEQ_HW.V4 (search for TRACKS_DOUT_L_SR and TRACKS_DOUT_R_SR)

   o copy function works correctly now if a track is pasted into another track
     with different partitioning in Paste/Clr = Steps mode (selectable in Utils->Options page)

MIDIboxSEQ V4.0beta36

   o The metronome function considers the "steps per measure" correctly now

   o received MIDI song position command sets the track positions correctly
     now - this is important when MBSEQ is controlled by a clock master.
     E.g. Logic Studio sends startpoint-1 when the sequencer continues
     in a loop

MIDIboxSEQ V4.0beta35

   o bugfix: step view displays steps >= 17 correctly again

   o bugfix: step length displayed correctly again in "step view"

   o new feature for more comfortable editing of multi-note tracks:
     if assigned parameter layer is Note or Chord, and currently 0, re-start at C-3 resp. A/2
     when value is incremented

MIDIboxSEQ V4.0beta34

   o implemented various "Edit Views".
     Press SELECT button to select the view in EDIT screen.
     Following views are available:
     - Step View: you already know it
     - Trigger View: left page allows to select the step, Gate,
       Accent, Roll, Glide, Skip, Random Gate and Random Velocity.
       Right Page allows to edit up to 8 parameter layers.
     - Layer View: allows to select the step, Gate and up to 14
       parameter layer. Especially nice for custom chord editing.
     - 303 View: provides a 303ish interface to select the Step,
       Gate, Accent, Glide, Octave, Note, Velocity and up to 9
       additional parameter layers
     - Step Select: allows to select the steps which are modified
       by the ALL function

   o glide trigger now handled (much) more 303-like

   o added testmode for AOUT interface connections.
     Enter "testaoutpin" in MIOS terminal for further informations

   o step record function now allows to define the step incrementer (+0..16)
     in "Record Mode" item

   o BLM keyboard mode: each column plays now an assigned drum instrument

   o new BLM entry mode 303:
     - first row selects accent
     - second row selects glide
     - third and fourth row select octave (4 different selections)
     - remaining rows select key of octave and set/clear gate

   o new session now initialized correctly after "SaveAs..."

   o optional "Tap Tempo" button is working now

   o optional "Left" button is working now in all menu pages

MIDIboxSEQ V4.0beta33

  o "SAVE AS.." name check now working as intended:
    - if filename is identical to current session, only the current 4 patterns will 
      be stored (like if you would push the SAVE button)
    - if filename is not identical, the current session will be transfered into
      a new directory

MIDIboxSEQ V4.0beta32

  o now it's possible to import/export songs/mixer maps/groove templates/local config as well


  o fixed pattern change on Normal->Drum tracks

MIDIboxSEQ V4.0beta31

  o a powerful session import/export function has been added.
    It allows you to copy one or multiple patterns to any session location.
    Both functions are available in the Utility->Disk page

  o "Save as.." shows the current session name as default name

MIDIboxSEQ V4.0beta30

    TRACK_DIRECTION page to MBSEQ_HW.V4 file

  o added LED and BUTTON function for FAST2, which is a second "fast" button with
    dedicated button behaviour. In distance to the common FAST button, the button
    behaviour is configured for push (and not for toggle) mode.
    The intended usecase is to use this function with push-button encoders.

  o Echo function: support for "dotted delays": 32d 16d 8d 4d 2d
    In order to keep existing patterns compatible, they are mapped to parameter
    value 16..21, but displayed/selected in the right order in the Fx->Echo page.
    Please note that it isn't a bug that 32d is displayed *after* 16T, 16d *after*
    8T etc - the entries are ordered by the resulting delay length!

  o a "Forward MIDI" option has been added to the record page.
    Previously events played by an external keyboard were always immediately 
    forwarded to the MIDI output. Now it's possible to disable this function for 
    keyboards w/o a "local off" function.

  o the quantization of recorded MIDI events is now freely configurable in the
    Record page.
    Than lower the percentage value, than lower the quantization (-> events not
    shifted to the next step)

MIDIboxSEQ V4.0beta29

  o implemented tap tempo function.
    It can be accessed in the BPM menu page (rightmost GP button), or with MENU+PLAY

  o fixed "accent on stretched notes" issue

  o fixed pattern synchronisation issue at very first played pattern in song mode

MIDIboxSEQ V4.0beta28

  o fixed bug in session load function which happened when no MBSEQ_GC.V4 file exists on SD Card

  o added new "udpmon <0..4>" terminal command which allows to monitor incoming and outgoing
    UDP packets, e.g. to debug OSC settings and/or to determine the port of incoming OSC
    In MIOS Terminal, use "udpmon 3" to display all packets with port number >= 1024

  o now we have a special CV configuration page which allows:
    - to select V/Oct, Hz/V and Inverse curve for each CV channel
    - the slew rate 0..255 mV for each CV channel
    - the pitch range (for pitchbend events)
    - the gate polarity for each CV channel
    - to calibrate each channel
    - to set the DIN Sync Clock PPQN Divider and Pulse Width
    - AOUT Module Type (previously hard-configured in MBSEQ_HW.V4 file)

  o each CV channel has now an own notestack.
    This is especially nice if AOUT channels are controlled through the MIDI Router
    from an external MIDI keyboard (live)

MIDIboxSEQ V4.0beta27

  o fixed a crash on rescheduled notes (caused by a gcc bug) - this bug only exists in beta26

  o BLM keyboard mode: now inverted (lowest button row plays highest velocity)

  o BLM keyboard mode takes octave/semitones transpose values into account

  o copy/paste function: if Paste/Clr track is activated in options menu, channel and
    port setting will be copied as well.
    This allows to copy&paste a complete track from one pattern to another.

  o Paste/Clr steps/track setting in options menu is now a global setting and will
    be written into MBSEQ_GC.V4 instead of (the session specific) MBSEQ_C.V4 file.
    In future versions it might be a good idea to move global settings into a separate menu page.

MIDIboxSEQ V4.0beta26

  o SD Card error messages will be sent to MIOS terminal

  o added MIOS terminal commands "play" and "stop", so that the sequencer can also be
    started/stopped from MIOS Studio

  o the status LED of the core module flashes on each beat now

  o bugfix for FAST button

  o OSC support for "Pianist Pro" format (an iPhone/iPad application)
    Now you can send notes and pitch changes from Pianist Pro to your
    MBSEQ, and convert them into MIDI events

  o support for a third MIDI IN/OUT port.
    The digital MIDI OUT signal (open drain!) is available at J5B.A6
    The digital MIDI IN signal is available at J5B.A7
    Note that the MIDI IO circuit (220 Ohm Resistors, optocoupler, etc.) is not
    part of the MBHP_CORE_STM32 module and has to be added externally.
    This IO port can especially be used for a dedicated BLM connection (this will
    be my personal usecase)

  o Gate #7 and #8, which were previously available at J5B.A6 and J5B.A7, are
    now available at J5C.A10 and J5C.A11

MIDIboxSEQ V4.0beta25

  o now each OSC port has an individual configuration set which consists of
    the Remote IP, Remote Port, Local Port and Transfer Mode

  o an OSC Transfer Mode has been added, it can be configured in the network
    configuration page for each OSC port.

    In MIDI mode, all events generated by the track will be embedded into a
    'm' type packet. This mode allows to tunnel MIDI events via ethernet to
    a proxy which runs on the host (or any device which is able to convert
    these messages)

    In "Text Msg (Integer)" and "Text Msg (Float)" mode, the OSC packets will
    be encoded the following way:
      - Note Events: /<chn>/note <note> <velocity>
        Integer: note and velocity in range 0 .. 127
        Float: note still as integer, velocity in range 0.0 .. 1.0
      - Poly Pressure Events: /<chn>/polypressure <note> <pressure>
        Integer: note and pressure in range 0 .. 127
        Float: note still as integer, pressure in range 0.0 .. 1.0
      - CC Events: /<chn>/cc <cc-number> <value>
        Integer: value in range 0 .. 127
        Float: cc-number still as integer, value in range 0.0 .. 1.0
      - Program Change Events: /<chn>/programchange <value>
        Integer: value in range 0 .. 127
        Float: value in range 0.0 .. 1.0
      - Aftertouch Events: /<chn>/aftertouch <pressure>
        Integer: pressure in range 0 .. 127
        Float: pressure in range 0.0 .. 1.0
      - Pitchbend Events: /<chn>/pitchbend <value>
        Integer: value in range -8192..8192
        Float: value in range -1.0 .. 1.0

    <chn> range: 1..16

  o OSC option now supports SysEx transfers (SysEx stream is embedded into blobs)

  o it's now possible to route USB/MIDI/IIC/AOUT ports to the OSC ports in 
    the MIDI Router page.

  o SysEx streams will now be forwarded by the MIDI Router as well.
    The Chn setting has to be set to "All" for source and destination port.

    This allows you to access the SysEx functions of your synth - it's even
    possible to upload a new firmware to a MIDIbox which is connected 
    to a MIDI port of MBSEQ now.

  o MIDI->Misc menu: BLM can now be assigned to an OSC port

MIDIboxSEQ V4.0beta24

  o support for OSC (requires MBHP_ETH module)
    4 OSC ports are available, currently they only send MIDI packets.
    A MIDI<->OSC proxy is currently only available for MacOS (on request)
    An easy to use Juice based Proxy is planned and will be released soon.
    (Firmware-)configurable OSC packets will be available in one of the
    next releases.

  o new network configuration page for the MBHP_ETH module

  o the debug terminal now supports a "network" command to retrieve
    the current status of the network configuration.

  o now we have global configurations which are stored independent from the
    session configuration in the "/MBSEQ_GC.V4" file 

    Following parameters have been moved to this file:
      - MetronomePort
      - MetronomeChannel
      - MetronomeNoteM
      - MetronomeNoteB
      - RemoteMode
      - RemotePort
      - RemoteID
      - BLM_SCALAR_Port
      - ETH_LocalIp
      - ETH_Netmask
      - ETH_Gateway
      - ETH_Dhcp
      - OSC_RemoteIp
      - OSC_RemotePort
      - OSC_LocalPort

  o probability parameter now incremented correctly in edit page

  o if the track plays multiple notes, gate is only cleared if
    all notes are set to "---"

  o BLM: triggers now displayed correctly in all stepviews

MIDIboxSEQ V4.0beta23

  o "external restart" sends FA at the right moment now

  o track transpose page now always starts with "semitones" item instead
    of "octave" item

MIDIboxSEQ V4.0beta22

  o running status optimisation can now be optionally disabled in
    the MBSEQ_HW.V4 file for MIDI devices that don't fully comply
    to the MIDI specification.
    Search for "RS_OPTIMISATION" in the MBSEQ_HW.V4 templates for
    further informations.

  o chaselight issue for mono colour 4x16 BLM fixed

  o trigger assignment page now works as intended in drum mode

  o new MIDI Bus parameters now loaded correctly after session change

  o another fix for crash if preset name is longer than 7 characters

MIDIboxSEQ V4.0beta21

  o ongoing preparation work for BLM16x16
    Features will be described under

  o the simple Transpose/Arpeggiator MIDI split function has been replaced by 
    a new bus routing concept.

    There are 4 busses that can be configured in the MIDI page.
    Each bus provides a dedicated MIDI port, channel and lower/upper MIDI note
    to define a keyboard range.

  o the bus can either be routed to the transpose/arpeggiator function ("T&A Mode"),
    or it can be used to play the currently selected track "live" ("Play Mode")

  o Track Mode page: now allows to select the bus over that the transpose/arpeggiator
    function should be controlled

  o Record function: whenever active, the MIDI port and channel used for recording
    won't be routed to Transpose/Arpeggiator/Play bus.

  o the "Roll" trigger now selects a 2D10 roll instead of 3D08 since it's more
    useful in most cases.
    In order to apply customized roll values, please use the roll function of
    the parameter layer instead of the Roll trigger.

  o implemented "Roll2" parameter layer function.
    This alternative solution to "Roll" allows to define the number of step repeats,
    and the distance between them.

  o added optional button/LED function for UNDO

  o fixed MIDI clock issue sent to USB5..USB8 (resulted into multiplied tempo 
    values in some DAWs)

  o CC assignment displayed correctly in mixer page

  o LFO CC not sent anymore if track is muted

  o fixed crash if preset name is longer than 7 characters

  o fixed step selection of copy function

  o inverted encoder behaviour in mute page: moving clockwise will unmute,
    moving counter clockwise will activate mute

  o if a previously "empty" pattern/map/song is stored without name, it will be
    labled with "unnamed" now.

  o LFO effect now works on CC parameters as intended

  o If a track is in CC mode, a CC/Pitchbender value will only be sent if
    the gate trigger is set.
    CCs/Pitchbender events are sent for each step regardless of the gate
    as before if the track is in Note or Chord mode.

  o transpose now works correctly on CC and Pitchbender values, but only if the
    track is configured for CC mode.
    Transpose will be ignored for CC/Pitchbender events if track is in
    Note or Chord mode.

  o AOUT gates now 0V after power-on

  o some minor bugfixes

MIDIboxSEQ V4.0beta20

  o taken over track/layer button/LED usage of MBSEQ V3 (important if you are
    using the old frontpanel):
    - pattern page: track buttons have the same function like group buttons.
      They allow to quickly jump between groups to select a new pattern
    - song page: track/group and parameter layer buttons can be used to 
      set the cursor position while editing a song entry

  o AOUT driver working again (was not working in beta19)

  o there is now a separate port/channel setting for recording, it can be
    directly changed in the UTILITY->RECORD page

  o the MIDI file import function now starts with the first track that contains
    MIDI events to ensure that MIDI file tracks are aligned properly to MBSEQ tracks.

    This is a workaround if the DAW uses the first track as a "master track" to 
    store tempo informations. Previously this always resulted into an empty 
    G1T1 track, and sequences started at G1T2.

MIDIboxSEQ V4.0beta19

  o changed order of instruments in initial drum map
    (HiHats now at position 3, 4 and 5)

  o implemented MIDI file import function (UTILITY->DISK->IMPORT)

    MIDI files have to be copied into the /midi directory of the SD Card.

    All tracks are imported at once (up to 16) in the same order they are stored
    in the .mid file. Accordingly, track assignments can be done within the
    .mid file before it is imported (e.g. edit the .mid file with your DAW)

    Currently only MIDI Notes and drums are supported (no CCs, no Pitchbender).

    To import drum tracks, change the import mode from "Note" to "Drum". This
    mode especially allows to control the velocity of each step separately.
    Currently drum instruments are only mapped to a pre-selection of 4/8/16
    notes - this map cannot be customized yet!

    Since MIDIbox SEQ is a step sequencer, notes will be quantised with a
    selectable resolution (16th, 32th or 64th).

    Also the number of layers/drum instruments is selectable (4, 8 or 16). 
    Than more layers are available, than more notes can be played at the 
    same step. In "Note" mode, all notes share the same velocity and length 
    value, in "Drum" mode each step and instrument has a dedicated velocity

    If the imported track contains different velocity or length values for
    polyphonic played notes, and this characteristic is important, it is 
    recommented to split the track into multiple pieces (e.g. for long and
    for short notes) and to import them into separate MBSEQ tracks.

    Another hint: if notes of the imported track don't start exactly at the
    16th/32th/64th note position (e.g. because they have a "swing" feel), it
    is recommented to quantize the notes in a DAW before the import.
    The swing feel can be added again after the import (GROOVE page).

    All tracks will be initialized depending on the selected resolution and
    layers before the import is started. Than higher the resolution, or than more
    layers are selected, than less bars can be imported (number of bars is displayed
    on screen).

    The MIDI port will always be set to DEFAULT during import. The MIDI channel will
    be set to the channel of the first played note (for each track separately).

    MIDI Files can be imported while the sequencer is running. This allows you to
    search for a certain file, but also to try different parameters during runtime.

  o some minor bugfixes

MIDIboxSEQ V4.0beta18

  o the current patterns/mixer map/song/groove templates will be cleared before 
    a new session is created.

  o last patterns now correctly selected after startup

MIDIboxSEQ V4.0beta17

   o implemented "Sessions" concept. Now you can change between different setups
     stored on a single SD Card
     See this page for more informations:

   o Sessions can be opened/saved/created in the main menu (press EXIT button)

   o your old session isn't lost, it's just at the wrong place.
     To take over this session:
       - enter MSD mode (UTILITY->DISK)
       - create a backup of all *.V4 files on your PC (recommented for Beta17!!!)
       - create a /SESSIONS directory if it doesn't exist yet
       - create a session subdirectory (8 characters maximum)
         if you name it "DEFAULT", it will be loaded after startup!
       - copy following files:
         MBSEQ_B1.V4, MBSEQ_B2.V4, MBSEQ_B3.V4, MBSEQ_B4.V4, 
         MBSEQ_S.V4, MBSEQ_G.V4, MBSEQ_C.V4
       - create a second session subdirectory
       - copy following files:
         MBSEQ_B5.V4, MBSEQ_B6.V4, MBSEQ_B7.V4, MBSEQ_B8.V4, 
         MBSEQ_S.V4, MBSEQ_G.V4, MBSEQ_C.V4
       - rename these files to MBSEQ_B1.V4 to MBSEQ_B4.V4
       - don't copy MBSEQ_HW.V4 (always read from root directory)
       - remove the copied *.V4 files from root directory, or move
         them to another directory for backup
       - unmount the SD Card on your computer
       - wait until MSD mode is disabled!
       - press EXIT, thereafter OPEN the session by pressing GP button 9

  o changed default track configuration to 256 steps/4 parameter layers
    since it's more useful in most cases

MIDIboxSEQ V4.0beta16

  o MIDI->Section Control: Octaves which are not taken for section selection
    can now be optionally forwarded to a configurable MIDI port.
    This saves you from adding a keyboard splitter to your MIDI keyboard, if
    you want to play a MIDI instrument from an unused keyboard zone.

  o fixed bug in live recording function (notelength sometimes not recorded correctly)

  o MIOS terminal functions have been added. Just enter "help" in the terminal
    which has been integrated into MIOS Studio 2

  o copy function now works correctly together with the section concept

  o Follow function now available as dedicated button and with key combination MENU+EXIT

  o the Follow Song option under UTILITY->Options has been removed. The selected
    follow mode won't be stored on SD Card anymore. Follow is deactivated after
    power-on and has to be manually enabled (e.g. by pressing MENU+EXIT)

MIDIboxSEQ V4.0beta15

  o Track sections which should be played can now be selected via MIDI
    Keyboard as demonstrated in

    Each group (G1/2/3/4) has a separate selection zone on the keyboard.
    Key C..B select section 1..12, the first key of the octave (C) plays
    the first section as usual, it has the same effect as if this feature
    is disabled.

    The width of a section depends on the track length.

    E.g., if the track length is set to 32, and if it consists of 256 steps,
    8 sections are available which can be selected with Key C/C#/D/D#/E/F#/F/F#/G

    It is recommented to activate the "Follow" function under UTILITY->OPTIONS
    when using this feature, so that the edit display gets automatically updated
    whenever the section is changed.

  o the MIDI configuration page has been overworked to handle the new parameters.
    Track sections can be selected from a dedicated MIDI Port and Channel.
    The keyboard zone assigned to the group can be changed, so that it's possible
    to merge groups (e.g. all 4 groups controlled from a single octave).

  o an individual section can be selected for each track in the StepView.
    Press & Hold StepView + SELECT button, then press the GP button of the
    appr. section.
    This feature is also nice for editing large tracks!

  o implemented CC#123 (All Notes Off) - it empties the note stacks if
    value 0 is received. Values > 0 will be ignored

  o bugfix for ALL button as reported by Gridracer

TODO for MBSEQ V4.0beta16
  o TODO: sections can also be selected with the BLM4x16 on the same way like
    with a keyboard. The currently active section is displayed by the LEDs.

  o TODO: sections can also be selected with the BLM16x16. In this case, we
    have individual selections for all 16 tracks.

MIDIboxSEQ V4.0beta14

  o prepared support for MBHP_BLM_SCALAR.
    The MIDI port can be configured in MIDI menu (MIDI->Misc.)

  o various minor bugfixes

MIDIboxSEQ V4.0beta13

  o pulsewidth of DIN Sync clock now definable in MBSEQ_HW.V4 file

  o Parameter/Trigger Layer selection can now be quickly incremented/decremented
    by pressing&holding Layer C button, and incrementing with Layer A button,
    resp. decrementing with Layer B button.

  o various minor bugfixes

MIDIboxSEQ V4.0beta12

  o Tracks can now be stored into/loaded from preset files on SD Card.
    This features opens some new possibilities:
    - you can store your favourite track configurations, melody lines, 
      drum loops, etc. in separate files to recall them later
    - you can prepare drum maps for different instruments
    - you can prepare CC setups for different instruments
    - you can share the files (which are stored in the preset/ directory)
      with other users
    - you can view and edit the files with a common text editor.

    The preset functions are available in the MENU->EVENT page

    You've to create a "presets" directory in the root directory of 
    your SD Card before using this feature (the DOSFS driver used 
    by MBSEQ doesn't support "mkdir")

MIDIboxSEQ V4.0beta11

  o paste function now only changes track partitioning if the track mode of
    target track is different. Other settings (number of parameter/trigger
    layers, number of parameter/trigger steps, number of instruments) won't
    be changed if track mode is equal.

  o bugfix for BLM_BUTTONS_NO_UI option

MIDIboxSEQ V4.0beta10

  o Tracks/Patterns/Songs can now be exported to a MIDI file.
    The appr. menu function is available under UTILITY->DISK->Export

  o a simple MIDI In/Out monitor page has been added.
    The page can be entered via MENU+MIDI->MIDI Monitor (GP 16 button).

    MIDI Clock and Active Sense events are filtered by default. The
    filter option can be changed by pressing SELECT in the MIDI Monitor page.

  o separated "pattern length" from "measure length" parameter in UTILITY->OPT menu.
    Pattern length is used for synchronized pattern changes, and measure
    length for the Synch-to-Measure function.

    The left encoder below the item allows to select 16 step wise, the right
    encoder and datawheel stepwise.

  o Paste/Clr behaviour option in UTILITY->OPT menu implemented now

  o HWCFG file option "BLM_BUTTONS_NO_UI" implemented now

MIDIboxSEQ V4.0beta9

  o If a sequence is already running, the MIDI file player doesn't cause a restart
    anymore. Instead in automatically synchs to the next 16 step based measure.

  o Track Event page: to trigger the Init function, GP16 has to be pressed for
    2 seconds (a message will be displayed to inform about this)

  o fixed various minor bugs

MIDIboxSEQ V4.0beta8

  o now your MIDIbox SEQ can play MIDI files, either exclusively or in parallel to
    the 16 sequencer tracks.

    MIDI files have to be copied into the /midi directory of your SD Card.

    To select a MIDI file, go to the UTILITY->DISK->PLAY page, and select
    the desired modes (Exclusive/Parallel and Loop on/off)

  o MIDI file import and export prepared in UI, but not implemented yet!

  o MIDI port used to send a SysEx dump now selectable in file list browser

  o fixed various minor bugs

MIDIboxSEQ V4.0beta7

  o a new label editor allows to enter track and pattern names so fast and easy
    like typing a SMS on a mobile phone. Use the first 10 GP buttons or encoders
    to cycle the characters (like on a telephone keypad), and the remaining
    buttons/encoders to select a character directly, move the cursor, delete/insert
    characters, selecting a preset (with the encoder) and to exit the editor.

  o implemented synchronous pattern change after x steps (x=1..256)
    This function has to be enabled in the UTILITY->OPT page.

  o implemented Follow Song mode. It has to be enabled in UTILITY->OPT menu.

  o a warning message will be print if Synch-to-Measure is enabled, and a 
    track length greater than steps per measure is selected.

  o CC number selected in Track Event and LFO Configuration page now has to be
    confirmed with GP button below the appr. item.
    A warning message will pop up to notify about this unusual data entry method.
    In addition, the value will be marked with '!' so long it doesn't match with
    currently active value.

  o fixed various minor bugs

MIDIboxSEQ V4.0beta6

  o now it's possible to send SysEx dumps stored on SD Card to MIDI devices.

    Preparation: create a directory called "sysex" on your SD Card, thereafter
    create subdirectories for each MIDI Device you want to use.

    For example:

    Now copy .syx files into these directories which should be sent to the
    devices later.

    Thats all! On your MIDIbox SEQ, change to the MENU->SYSEX menu, the
    devices will be displayed on screen. Select a device to browse through
    the file list. Select a file to send the dump.

    Note: currently .syx files are only sent to the Default port (selected in
    MIDI page). A "store .syx dump" function is planned for later releases.

  o Menu page shows the current sequencer position in measure.step.microstep

  o "About this MIDIbox": separated SD Card Info

  o fixed various minor bugs

MIDIboxSEQ V4.0beta5

  o overworked menu page selection (now uses new list browser)

  o added new info page "About this MIDIbox" (at the end of menu list) to
    simplify support.
    A lot of additional informations are sent to the MIOS Terminal when 
    an item (displayed at left page) is selected with a GP or the SELECT
    button. Use the datawheel or a GP encoder to browse through the list.

    MIOS Terminal is part of MIOS Studio, a command line tool for MacOS 
    available as well.

  o Length 128/256 quick selection won't be displayed anymore if track
    partition doesn't allow this number of steps

  o fixed various minor bugs

MIDIboxSEQ V4.0beta4

  o MBSEQ Parameters are controllable via NRPN messages from external MIDI devices now.
    See also doc/mbseqv4_cc_implementation.txt

  o these parameters can also be controlled via Internal Loopback (Bus1 Port).

  o Loopbacked CC Parameters are print in text format when edited

  o implemented MIDI Remote Keyboard function (note: MBSEQ_HW.V4 has been updated)
    See also doc/mbseqv4_remote_functions.txt

  o fixed various minor bugs

MIDIboxSEQ V4.0beta3

  o if global loop mode enabled, a "*LOOPED*" message will flash at the 
    right corner of the EDIT and STEPVIEW screen.

  o following handling has been added to realize a "smooth startup" for
    people who are in the progress of building their MBSEQ. The core is already
    running, they connect a SD Card but don't have LCDs (so that messages
    cannot be read):
      - if a SD Card without Banks/Songs/Mixer Maps is connected, the appr.
        files won't be created automatically anymore.
      - messages are print on the PATTERN/SONG and MIXER page to inform
        that files have to be created from the UTILITY->DISK menu
      - in the DISK->UTILITY menu you will find a special option at the left
        side which allows to start the formatting process (in fact, the SD
        Card won't be formatted, but some files will be created)
      - there is now a nice progress bar which informs about the state
        so long formatting is in progress

  o CLEAR button has to be pressed for 2 seconds before action is triggered

  o fixed BLM inversion mask configuration

MIDIboxSEQ V4.0beta2

  o Song page got a copy/pase/clear/insert/delete function for song steps.
    Press the SELECT button to select the utility function

  o Copy/Paste/Clear button can be used in song page as well

  o Song/Phrase mode not switched via SONG button anymore (this handling
    is an artifact from MBSEQ V2/V3)
    Instead, the mode can be changed with GP encoder #8 or #9

  o a 16 step selection pattern for the ALL function is now available
    (only selected steps will be touched by the ALL function).
    It can be changed by pressing the SELECT button in EDIT page.

  o the 16 instrument labels of a drum track can be edited now

  o a nice graphical logo is now print during startup

  o lower CPU load if no SD Card connected

MIDIboxSEQ V4.0beta1

Initial public release.
Short list of changes:
  o uses the new MBHP_CORE_STM32 module (ARM Cortex M3 based derivative)
  o firmware completely rewritten in C - it can be optionally emulated 
    under MacOS
  o patterns/songs/grooves/configs/etc. now stored on SD Card in a FAT32 
  o USB MIDI natively supported, MIDI events are sent more than 100 times 
    faster to a DAW/virtual synth
  o two "common" MIDI IN and MIDI OUT ports, up to 8 additional MIDI OUT 
    ports can be added with MBHP_IIC_MIDI modules
  o track length increased to 256 steps
  o track memory can be partitioned, e.g. 64 steps and 16 parameter layers, 
    or 256 steps and 4 parameter layers. Each track provides 8 trigger layers
  o resolution increased to 384ppqn (16 times faster than common MIDI clock)
  o new MIDI event scheduler concept priorises and sorts queued MIDI events
  o new parameter layer options like "Pitch Wheel", "Roll" and "Probability"
  o special drum mode for easier editing of percusive patterns
  o additional chords (now: 32 in Major/Minor scale)
  o new track progression parameters like "Interval/Repeat/Skip"
  o groove templates can now be customized and stored on SD Card
  o Echo Fx with variable number of repeats, damp, tempo change, note 
    incrementer (can be forced to scale!)
  o LFO Fx with different waveforms, synchronized to track clock, step based 
    selection of period and reset, assignable to Note/Velocity/Length
    + separate CC with definable ppqn resolution
  o value range Limiter Fx
  o Loop Fx (also nice for editing)
  o overworked realtime record function with better quantisation
  o hardware configuration file now read from SD Card. No need to recompile 
    the firmware on changes.

Wishlist for future features

  o SysEx librarian, recording and dumping function for external Synths or 
    other MIDI gear
  o finish the remote access function, which allows to control multiple
    instances of MBSEQ (either running on MBHP_CORE_STM32 module or in
    simulation) from a single CS (partly working, can be enabled in the
    OPT menu, but not very user friendly yet)
  o allow to switch between different sections of a track (A/B/C/D function
    like known from MB808)
  o "Preloading steps" as proposed by Gridracer:
     Layer A is already active-> I press it again-> LED goes off or starts 
     blinking. I change the note numbers of the steps without setting them, 
     (audience hears nothing) -> I push Layer A again->  LED is On again. 
     Now I can set the new steps which will now play the intended
     notes right from the beginning.
  o SysEx dump for patterns/songs

Additional input from vcfool:

>> [/quote]
>> Yes, I know I can do it like this, but...

>> Then I have to make a special cable to route that Gate output to a DIN5 (ok, i already have the cable, ok).
>> But most important it makes the Clock output useless in most situations if you use grooves (and I do love grooves).
>> I use the Clock output not only for the DIN-Machines but also on my modular too. So I'd love to have this implemented. I don't know how much coding this implies. I feel a little bad asking for things ......... of course ultra-low priority if any.

TK: low priority


>> -AOUT Gates do not make "Legato" correctly. --> Needed to detail...

TK: TODO... (will be some work that hasn't been done yet)


>> -Changing ALL Length is odd ... more explaining to do ....

>> -When changing the Length value of ALL notes it would be nice that only the actual inserted (Gate ON) Notes would chnage it's value. The issue I find is like this:
>> INIT a track to get C3 quarter notes at steps 1,5,9,13. We can use this as an example. Press ALL. Increase the Length value. Once it has reached the first 16th note, first Glide, all the notes will be togheter as the empty notes also got the Length increased.
>> I would like to be able to continue increasing the Length of the second 16th note (steps 2,6,10,14) to reach for a 8th note duration, and so on.
>> -If I am making myself clear...  with the actual ALL concept, I know this would probably be hard to code, like the Fast button-changing Octaves suggestion I made sometime before.
>> -Also, I found myself several times wanting to change the Length and Vel. and moving the Encoder won't do anything. I needed to go to Event page and moving the Parameter Layer Assignement (Vel. -> Whatever -> back to Vel.) would make it possible to edit again. I still haven't found the exact things causing this, to know how reproduce it.


>> SYSEX Files
>> -Problems dumping big files (64k of AKAI S612 sample data) over IIC Outs, works fine one the Core OUTs, but LCDs show nothing and SEQ seems frozen. Tried with the SEQ playing, just for fun: it will Stop, and then Continue when the Dump is sent. 
>> -Sending the same file from a computer (MIDI-OX) to the MB-SEQ USB1 IN, and routing it to a Core or IIC out, would not work correctly (MIDI TimeOut Protocol). --> GM-5 will work flawlessly here, not a PC problem.
>> -Also tried real (not-USB) MIDI, using a SySex editor on the ATARI ST. ATARI OUT -> SEQ IN2 -> routed to OUT2 -> S612. This won't work either.
>> -Would be nice if the OUT used to send the files for 'each' Sysex folder could be remembered by the SEQ. For a really intrument-ready folder.
>> -Scolling through the .SYX files with the DataWheel, makes the PAUSE LED to turn ON (when reaching the ends of the page). Trigger Layer C LED blinks too. This also happens when browsing .MID files in the MIDI folder.
>> -Note: I never experienced a problem with smaller files (6 bytes of FX data to a GM module) doesn't cause any trouble, and are sent with the SEQ running and no hicupps whatsoever... and using both Core and IIC outs caused no problem at all.
>> -I can send the files if you want to test on them.

TK: I know the reasons. Some can be solved, some others not (like that the sequencer is stalled on large SysEx dumps)
Technical answer: there is only one Mutex for all MIDI output ports.
Multiple Mutex (semaphores) will decrease the general performance

>> About SysEx Files:
>> Let me make myself clearer.
>> -I don't expect the SEQ to be playing while sending those big sample data files. All the mentioned tests were done with the SEQ stopped. Only tried once while playing, just to see what happened.
>> -I just remarked the fact that, with the SEQ stopped, sending the file won't work on IIC OUTs. Only works on the CORE OUTs.
>> -The LCD could show "Sending..." or something, so you know the SEQ hasn't crashed or anything.
>> -The actual "xxx bytes Sent" message appears correctly at the end. And BTW, it would be nice that it would not appear over the files, because it takes so long to disappear and when sending small .SYX files (while the SEQ is playing, jamming with synth values on-the-fly) there's this time when you won't see the files in there. So maybe using only the upper LCD lines...


>> I have a question regarding the arpeggiator (and transposer)
>> I noticed that the arpeggiator (and transposer) behave different when they are contorlled from external eg. keyboard or from an internal track:
>> - If the contorl notes come from external, the settings HOLD and RESTART work as they are described in the manual
>> - If the contorl notes come from an internal track, the arpeggiator (and transposer) always behaves like if HOLD is ON and RESTART is OFF,
>> no matter to which value they are actual set.

TK: the handling of loopback tracks differs from normal tracks. MIDI Events are sent
immediately to the transpose/arpeggiator function instead of using the scheduler, so that
note changes take place immediately and independent from the track number before new
MIDI events are scheduled.
Disadvantage of this method: note off events won't be generated, accordingly the gatelength
won't be considered and HOLD/RESTART of transposed tracks won't work as expected.

Possible solution: gatelength counter for note off events, only used for loopbacked tracks.
Problem: how should polyphonic loopback tracks be handled?
It could be sufficient to call SEQ_MIDI_IN_ResetTransArpStacks(<bus-number>) depending on
the gatelength


 would it be possible to get a "tempo" button just in the way of scrub? Just a shortcut to the bpm menu and selecting the current speed as long as it is pressed? This would be very cool for live tempo fades ;-) (i am aware of the very nice tempo preset button and page)


in the fx section , theres the humanizer which now can "randomize" notes, vel/cc and length...but since the whole right screen is empty, wouldn´t it be cool to have the trigger layer "humanized" also?...maybe with a percentage-value like probability...
so it would be possible to have some nice variation with accent, slide , rolls, random value etc... each with it´s own amount...?! 

FFW: Für den Humanizer könnte man rechts im Display die Möglichkeit einfügen,
den / die CC´s auszuwählen, auf welche sich der Humanizer beziehen soll.


It would be usefull to have a mixer page to send also relative de/increment values.

FFW: Man könnte bei der Global-Loop FX Funktion im rechten Display eine Option anbieten,
welche es ermöglicht, den Loop quantisiert ein-/aussetzen zu lassen.
Also zb der Loop setzt, nach Aktivierung (drücken des "on" Tasters) auf 1/8 Takt etc. ein.

Has the possibility of routing a track output to another tracks input ever come up?

Alex:  I'm wondering if being able to control AOUT tracks with the LRE8x2 (MBNG) is possible yet? 
I have my ssm2044 boards hooked up to the AOUT_NG, and would like to use encoders to control cutoff and resonance through NRPN messages.

SAVE page, name entry: usability wise, it would be useful if pressing the <> button (GP#12) toggled cursor position between the first character of the category and the first character of the name.
MIDI Remote Control function:
Here's an idea to extend this:  It's really great to be able to quickly set CC values with a midi controller potentiometer.  It's so quick and easy to get the value to where you want it - much faster than an encoder.  It would be great if you could set all the parameter layers this way.  If the SEQ provided external CC controller numbers that were assigned to "adjust parameter layer 1", "...2", "...3" ...16 for the currently held step, then you could use an external midi controller to easily adjust all parameter layers for the currently held step without having to wade through the menus.
For example, you could set up a Korg nanokontrol (has 8 faders and 8 potentiometer knobs) so that each fader and knob controlled one parameter layer - so one fader would control velocity, one length, probability, etc...  Depending on how you initialized your track.  Hold a step, move some faders/knobs on the nanokontrol to quickly adjust parameter layers.
Some users might not want external faders/knobs to be able to change values in note or chord parameter layers, so maybe an option could be provided to enable/disable external control of chord and note layers via CC
...and to extend the idea even further:  The SEQ could also provide external control CCs for the trigger layers, so the trigger layers could also be quickly enabled and disabled from an external controller when a step button is held.
You could even activate the LED indicators on the nanokontrol or other midi controllers with LED button indicators by sending MIDI values >0 (anything >= 1 works on most, 127 is required on some controllers, some controllers with multicolor leds require specific values to light certain colors - sending a 1 would be a good default for the "on" state) out from the SEQ on the CC #s for the trigger layers that are active, and sending 0's out to the CCs that are inactive.  This would light the LEDs on a lot of commercial controllers without any further programming on the SEQ.  So the LEDs would toggle on and off to indicate the state of the corresponding trigger layer.
For the nanokontrol2, you have to use the korg software to set the LED control to external.  Then, sending a 0 on the right channel to the MIDI CC assigned to a button will turn the LED on that button off, sending a 1 will turn it on.
With USB Host working on the STM32f4 core and this feature implemented, a nanokontrol would be a really cheap way to extend the functionality of the SEQ - I can imagine a lot of other uses for a nanokontrol in other modes on the SEQ as well.  Lots of buttons and faders on a nanokontrol for ~$60.
Here's the Nanokontrol's midi implementation/ parameter guide -
This could also work on a keyboard with CC-assignable knobs and faders, or any other MIDI controller with assignable controls, of course.
Provide trigger layer function for Random Velocity and CC
BLM enhancements:

- round step buttons along the top light in dim yellow to indicate which steps in the currently visible measure have notes set? and
- when ALT is held (to switch octaves), round track buttons on the right side light to indicate which octaves have notes set?
- copy/paste using the top row of step view buttons: ALT+step button copies that measure, keep holding ALT and press another step button to paste the copied steps into the second step view.  Keep holding ALT and press a third, 4th, 5th, etc. step button to paste the copied steps into additional step views.  Release ALT without pressing a second step button to cancel out without pasting.

Wishlist for MIDIbox SEQ V4 Plus

V4 Plus will require a STM32F4 core which offers much more memory.
Accordingly, resource hungry features could be implemented.

Here a list:

- Expression Layer:

- Audio metronome function

- allocate some memory to sort the directory view instead of loading directly from SD Card

- allow to define delays based on ports & channels instead of only the port.

- MIDI filter
