MIDIboxSID V2.044

~~~~~~~~~~~~~~~~~

   o This version got an improved rotary encoder handling.

     Please update to MIOS V1.9h before uploading the application, otherwise the improvements

     won't be effective.

   o swapped behaviour of ENC speed control again, so that encoders are at fast speed

     by default, and slow if SHIFT button pressed.

     This behaviour can now be alternated in your setup_*.asm file by changing

     the DEFAULT_SHIFT_SPEED_CONTROL_MODE option

   o implemented special encoder testmode which can be enabled with

     DEFAULT_TESTMODE_ENC_SPEED in the setup_*.asm file

   o envelopes are now released properly when a note is played via the SysEx editor

     (or with the PLAY button)

   o added new "SuperSaw" detune mode which has been created by Lis0r.

     In distance to the normal (legacy) mode, results are much better especially on

     higher detune values!

     The detune mode (DtM) can be selected in the OSC page for lead engine patches, and

     in the O23 page for bassline patches.

MIDIboxSID V2.043

~~~~~~~~~~~~~~~~~

   o fixed NRPN handling for Multi patches

   o implemented CCs for Bassline/Drum/Multi Engine

     See doc/mbsidv2_cc_chart.txt for available CCs

   o display updated when the patch name has been changed from external

MIDIboxSID V2.042

~~~~~~~~~~~~~~~~~

  o new SysEx commands to support the Lemur Editor

  o MIDI Clock is now optionally sent with the "Out" option of the Ensemble Clk page.

  o default encoder mode is "DETENTED3" now, since it works better for most encoders

    available on the market

  o swapped behaviour of ENC speed control: encoder now at fast speed if SHIFT button is pressed

MIDIboxSID V2.041

~~~~~~~~~~~~~~~~~

  o corrected sysex handling for MIOS Studio SysEx Librarian

MIDIboxSID V2.040

~~~~~~~~~~~~~~~~~

  o fixed SysEx patch write issue which happened when patches were received

    with the common format (e.g. preset patches)

MIDIboxSID V2.039

~~~~~~~~~~~~~~~~~

  o LFO MIDI Clock Sync has been overworked, it now supports 32 different

    rates from 16 bars to 1/32 notes including triple and dotted delays!

    If the CSn flag enabled the available rates are:

    0=LFO disabled, 8=16 bars, 16=14 bars, 24=12 bars, 32=10 bars,

    40=9 bars, 48=8 bars, 56=7 bars, 64=6 bars, 72=5 bars, 80=4 bars,

    88=3.5 bars, 96=3 bars, 104=2.5 bars, 112=2 bars, 120=1.5 bars,

    128=1 bar, 136=1/2., 144=1/1T, 152=1/2, 160=1/4., 168=1/2T,

    176=1/4, 184=1/8., 192=1/4T, 200=1/8, 208=1/16., 216=1/8T,

    224=1/16, 232=1/32., 240=1/16T, 248=1/32

    Note that in MIDI Sync mode, the LFO Delay won't work because

    the appr. resource is used as MIDI clock counter.

  o current bank and patch number won't be changed anymore on direct RAM

    access via SysEx

MIDIboxSID V2 RC38

~~~~~~~~~~~~~~~~~~

  o optimized MBNet Handler for fast external access to SID registers

  o added DEFAULT_CC32_FILTER switch to setup_*.asm - it filters CC#32 for

    programs which send this CC always together with CC#0 on bank changes

  o support for "extended SysEx dump" - see also mbsidv2_sysex_implementation.txt

  o filter mode/channel and waveform flags can now be optionally passed to

    J5 (configuration has to be done in setup_*.asm file)

  o (only for Multi Engine): "W+16" flag - waveform can be changed from

    offset +16 of the wavetable, in combination with another parameter

    (such as #249), it's possible to control pitch and waveform from

    a single WT track

MIDIboxSID V2 RC37

~~~~~~~~~~~~~~~~~~

  o SW based feedback loops won't lead to endless repeated replies

MIDIboxSID V2 RC36

~~~~~~~~~~~~~~~~~~

  o Bassline engine: detune parameter now mapped to Parameter #003

  o a table based calibration table is now provided for the SID filter.

    It has to be adapted under src/sid_filter_table.inc and can either be

    uploaded together with the firmware build, or separately if by uploading

    "sid_filter_table.hex" after the "make" command (type "make sid_filter_table"

    to build only this file)

    The table can be used to compensate technology related non-linearities

    of the 6581 R-2R DAC

  o various minor bugfixes

MIDIboxSID V2 RC35

~~~~~~~~~~~~~~~~~~

  o modulation source "KEY" now uses current frequency instead of key number

    to consider frequency sweeps correctly

  o bugfix for "jump to page" (empty page if current item position outside new page)

  o bugfix for knob page (min/max value modified Pa1 if multiple SIDs selected)

MIDIboxSID V2 RC34

~~~~~~~~~~~~~~~~~~

  o fixed race condition in SusKey portamento function

  o Note Off keys which are not in the note stack are ignored now

  o implemented CC#123 (All Notes Off)

    Complies to MIDI spec. Means: only CC#123=0 will unplay all notes,

    all other values (1..127) are silently ignored

  o new wavetable control function "Key" allows to select a wavetable

    step with the currently played note inside the given Begin/End range.

    E.g., with Begin=0x00, End=0x7f, KEY=on, Par=200 you are able to

    define different ENV1 Decay parameters for each note.

    There are much more usecases of course (e.g. different LFO values,

    different waveforms, Sync/Ring enable/disable in certain keyranges)

    - be creative :)

  o Arpeggiator "Easy Chord" function now active in default Lead/Bassline/Multi

    patch

  o sammichSID: F2 button now jumps to Knob page by default (especially

    nice for bassline patches, for other engines the knob assignments

    are mostly not preconfigured)

  o Multi Engine: Knob parameter #6 and #7 now allow to control CutOff

    frequency of left/right channel SID separately. Note that this isn't

    consistent to Lead/Bassline assignments, but unfortunately there is

    no other possible solution.

  o filter page now allows direct L/R channel selection

  o the full control surface now handles the first press of Osc Select,

    Env Select, LFO Select and Filter Mode/Channel Select as a

    "jump to page" function if that page was not displayed, and

    thereafter, function as a "change selection" function. Thus

    if you are not on the LFO page, pressing LFO Select jumps to

    LFO page, and then pressing it again will change the selected LFO.

  o this is the christmas edition, therefore the Matrix LEDs are flickering

    during startup ;-)

MIDIboxSID V2 RC33

~~~~~~~~~~~~~~~~~~

  o built for MIOS V1.9g (or higher) to support new encoder types.

    Rotary encoders won't work with older MIOS versions!

    Note that MIOS only has to be updated on the master SID, as encoders

    are not connected to SID slaves anyhow.

  o a new LED matrix visualisation mode for sammichSID has been added

    which is selected with DEFAULT_LEDMATRIX_MODE 2

    - Lead and Bassline engine: 6x8 LEDs show VU meters for OSC frequency

    - Multi and Drum engine: 6x8 LEDs show animated VU meters for OSC triggers

    - ASID player mode: 6x8 LEDs show animated VU meters for OSC triggers

  o animated VU meters are a bit faster now

  o a special configuration file and prebuilt binary for sammichSID

    is now part of the release package -> setup_sammich_sid.hex

MIDIboxSID V2 RC32

~~~~~~~~~~~~~~~~~~

  o fixed strange Oct display output in Bassline Sequence Editor

  o added "DEFAULT_ENABLE_UPPER_WAVEFORMS" switch to setup_* files to enable the

    selection of additional waveforms for SwinSID

  o overworked Meter display mode in Bassline Mode (enjoy the effect! :)

  o changed behaviour of Play button: now it plays all SIDs regardless if they

    are selected or not.

    Dedicated SIDs can be played by pressing & holding the appr. SID buttons

    before pressing PLAY

MIDIboxSID V2 RC31

~~~~~~~~~~~~~~~~~~

  o fixed storing ensemble in internal EEPROM if no BankStick selected

  o the ensemble stored in internal EEPROM (previously called E001) is now called EInt

  o the patch stored in internal EEPROM (previously called [A-H]001) is now called PInt

  o EInt now automatically selected after startup if no ensemble BankStick connected

  o E002 now automatically selected after startup if EInt was selected before

  o fix for communication with Rutger's SysEx editor: mod matrix direct assignments

    are handled correctly now in stereo edit mode

MIDIboxSID V2 RC30

~~~~~~~~~~~~~~~~~~

  o fixed OSC button behaviour (OSC selection corrupted on page changes)

MIDIboxSID V2 RC29

~~~~~~~~~~~~~~~~~~

  o fixed CC#07 (now controls volume as intended)

  o for 4x20 LCD: MIDI channels and Engines of selected ensemble are displayed at upper line

  o OSC button now cycles between 1--, -2-, --3 and 123

  o added optional CS_MENU_BUTTON_Arp function, which can be assigned to a button in setup_*.asm

MIDIboxSID V2 RC28

~~~~~~~~~~~~~~~~~~

  o fixed arpeggiator note handling bug

  o arpeggiator: the previously hardcoded "experimental arp behaviour" switch is now

    available as software controlable switch called "Easy Chord".

    It has to be enabled in the ARP menu ("Esy" flag)

    Difference compared to normal chord entry: depressed keys will still

    be cylced by the arpeggiator until a new key is pressed.

    This feature is especially useful when slow arpeggios are played, since

    it avoids unintended "long notes" on chord changes.

    It is not useful if you intend to play a voice like a common lead instrument,

    which should turn into a fast arpeggio when more than one key is played

    (in this case, ensure that the "Esy" switch is disabled)

  o fixed drum model handling (listen to the drum patches again - they sound much better now :)

  o preliminary support for parameter access via 7bit CC

    (only available for Lead Engine yet)

MIDIboxSID V2 RC27

~~~~~~~~~~~~~~~~~~

  o Super Poly voice queue now handled centrally from master.

    Slaves notes are triggered via MBNet

  o SPV value now changed simultaneously for all slaves

    It can only be changed if master SID selected

  o PLAY button now plays a chord in superpoly mode

  o Mod matrix changes forwarded to all selected SIDs

MIDIboxSID V2 RC26

~~~~~~~~~~~~~~~~~~

  o various improvements for Super Poly Mode and SysEx distribution via CAN

MIDIboxSID V2 RC25

~~~~~~~~~~~~~~~~~~

  o improved "SusKey" (fingered portamento) handling

MIDIboxSID V2 RC24

~~~~~~~~~~~~~~~~~~

  o voice allocation of multi engine working again

  o Lead engine: MdW (ModWheel) and Key modulation source now provide a value in

    positive range only

  o overworked oscillator pitch handling: now completely linear frequency

    calculations.

    Advantages:

      - modulation frequency (e.g. LFO vibrato) independent from oscillator frequency

      - accurate filter key tracking

      - the O2A option (forward pitch to AOUT) doesn't result into out-of-scale

        SID frequencies anymore

  o the presets under presets/v2_vintage_bank.syx have been overworked according to

    the new osc frequency handling

MIDIboxSID V2 RC23

~~~~~~~~~~~~~~~~~~

  o finetune is working properly again

MIDIboxSID V2 RC22

~~~~~~~~~~~~~~~~~~

  o "menu labels" (activated if DEFAULT_LCD_LINES >= 3) now completely implemented

  o added keyboard transpose function for bassline sequencer. MIDI channels and

    keyboard zones have to be configured for L/R bassline separately with

    ensemble instrument 3 and 4. The transposer uses C-3 as base note.

    Example configuration:

    Ins1 Chn 1 SpL C-3 SpU B-3 Trn 0     L Bassline sequence selected with key C-3..B-3

    Ins2 Chn 1 SpL C-4 SpU G-8 Trn 0     R Bassline sequence selected with key C-4..

    Ins3 Chn 1 SpL c-2 SpU B-2 Trn +12   L Bassline sequence transposed with lower keys until B-2

    Ins4 Chn 1 SpL c-2 SpU B-2 Trn +12   R same as for L

    "Trn +12" is required in this setup to compensate the octave range of the transposer

    (base note C-3 is outside the selected keyboard zone c-2..B-2)

  o bassline and drum sequences not stopped anymore on patch changes

  o random generator for bassline O23 settings

MIDIboxSID V2 RC21

~~~~~~~~~~~~~~~~~~

  o added "Log" flag to ENS->FIL menu: cutoff frequency converted through log function

    to achieve better linearisation of 8580 filter

  o Filter Keytracking parameter now also available for Lead Engine, the scaling has been slightly

    changed, so that the maximum value 255 leads to 1:1 tracking (e.g. if 8580 Log function activated,

    or an external filter is connected)

  o added "DOR" flag to the ENS->SID menu: Disable automatic Oscillator Reset during patch change

    could also be called DAORDPC flag ;-)

  o MB-6582 setup: swapped page up/down button, added Inc/Dec button function

  o support for 4x20 LCD has used for MB-6582: DEFAULT_LCD_LINES and DEFAULT_LCD_LINE_Y* can

    be configured in the setup_*.asm file

  o MB-6582 screen now centered at 2nd and 3rd line

  o if DEFAULT_LCD_LINES >= 3, the name of the menu will be print at the upper line

  o if DEFAULT_LCD_LINES >= 4: the value of the currently edited parameter will be displayed

    as horizontal bar graph at the lower LCD line

    TODO: display bidirectional parameters like "depth" with a left/right splitted graph

    TODO: update when a new OSC/Channel/SID is selected

  o the "blinking LCD cursor" which was set to the selected parameter position is

    disabled by default now (DEFAULT_LCD_PRINT_CURSOR set to 0), since it clashes with

    the horizontal bar graph output routine

  o added experimental features to bassline engine:

    - new menu page O23 which allows to use OSC2 and OSC3 as slave oscillators

    - waveforms of slave oscillators can be selected separately

    - individual sync and ringmod flags

    - individual octavewise transpose

    - individual pulsewidth

    - optional static note (decoupled from master osc) for nice sync/ringmod effects or chords

    - phase offset

    - detune

    - TODO: Knob assignments and maybe more functions

MIDIboxSID V2 RC20

~~~~~~~~~~~~~~~~~~

  o Multi Engine: arp handler working properly again

  o Lead Engine: ENV encoder section working properly again

  o increased startup delay, so that slave cores will be found even if no BankStick connected

MIDIboxSID V2 RC19

~~~~~~~~~~~~~~~~~~

  o Enhancements for SysEx Editor

    (see also doc/mbsidv2_sysex_implementation.txt)

    - introduced <WOPT> function which allows to change parameters of

      multiple voices with a single SysEx command

    - introduced <sids> selection which allows to access slave SIDs

      via master SID (command 0C 00 <sids>)

    - added SysEx command for all notes/sequences off (command 0C 08)

    - added SysEx command to play the current patch (command 0C 09 [<ins>])

      Note: for proper handling of <ins>, separate keyboard zones or MIDI channels

      for multi instruments are currently required - this is no bug,

      but just an imperfection (I was too lazy to overwork SID_PATCH_NotesOn yet)

  o parameter assignment/patch/bank selection: "big message" now displayed

    immediately when menu item has been selected

  o The "note off" function of the SHIFT menu now works as "Note On/Off" (called "Ply")

    This function is intended as replacement for the optional Play button

    Patch will be played/stopped on all selected SIDs

  o Removed button combination "SIDx+MENU" (which was previously used for Play function)

    This combination could get a different purpose on future

  o LFOs and ENVs of right channel bassline working properly again

  o AOUT_LC driver now supports 12/12/8 resolution (requires 4 combined 74HC595)

MIDIboxSID V2 RC18

~~~~~~~~~~~~~~~~~~

  o modulation matrix: comparison operators >, < and = now return 0 instead

    of full negative value if comparison is false

  o changed SusKey handling, so that it also works in Mono mode (previously

    it was only working in Legato mode)

  o SusKey and Legato flags now accessible in Bassline CFG menu

  o Individual Attack/Decay/Release Curve assignments now accessible in

    Multi/Bassline ENV menu

  o Trigger Matrix: since the BPM clock generator concept has been changed in

    one of the previous releases, we now have a Clk/6 and Clk/24 trigger instead

    of Clk/4 and Clk/16

  o LFO and ENV MIDI sync working properly again

  o portamento omitted after patch change when first key is played

MIDIboxSID V2 RC17

~~~~~~~~~~~~~~~~~~

  o switched from MPASM to gpasm

    code now under version control (SVN)

MIDIboxSID V2 RC16

~~~~~~~~~~~~~~~~~~

  o "ENV Misc" layer added for MB6582 Control Surface

  o SIDPlayer: lower line now always cleared when new LCD message

    is sent by host

  o changed encoder speed behaviour: values incremented fast by

    default now. Incrementer is slowed down by pressing the SHIFT button

    (previously it was the opposite behaviour)

MIDIboxSID V2 RC15

~~~~~~~~~~~~~~~~~~

  o improved FIP function (linear interpolation of filter cutoff) - it

    is working now the same way as implemented in MIDIbox CV

  o F2A and V2A flags moved to new storage position in ensemble - old

    ensemble setups (where F2A and/or V2A was set) have to be adapted!

  o added new AOUT forwarding functions:

     - P2A (Pulsewidth-to-AOUT)

     - K2A (Key-to-AOUT)

     - O2A (Oscillator Frequency-to-AOUT)

    Channel assignments have to be adapted in setup_*.asm - all channels

    are disabled by default

  o added functions to forward the 6 gates/slide/accent signals to the

    digital outputs at J5. Assignments have to be configured in the

    setup_*.asm file.

    Note that DEFAULT_J5_FUNCTION has to be set to 3 in order to

    enable the digital output function of CORE:J5

MIDIboxSID V2 RC14

~~~~~~~~~~~~~~~~~~

  o BankStick write via SysEx now gracefully aborted if only 32k BankStick

    is addressed and patch number >= 065

    SysEx error number 0x11 ("BankStick too small") will be returned in this case

  o the "send dump" function of the "shift menu" now sends the edit buffer

    of the selected SID, which also includes the corresponding device ID.

    BankStick content won't be overwritten if such a dump is sent back.

  o menu page automatically changed to the previous selection if SID master

    or slave selected which is running with a different engine

MIDIboxSID V2 RC13

~~~~~~~~~~~~~~~~~~

  o multi engine: improved approach for routing LFOs to filters (only

    LFO of last assigned voice will be used for more predictable results)

  o reduced intensity of LFO pitch modulation for multi and bassline engine

    (Lead engine: intensity can be reduced by decreasing the depth

    of the modulation path)

  o 8 external switches can now be connected to

     - DOUT shift register (-> DEFAULT_EXT_SWITCH_DOUT != 0)

     - port J5 of the core mode (-> DEFAULT_J5_FUNCTION == 3)

    The switch states are stored in the patch structure, and

    can be accessed via Control Surface (EXT menu) or via Parameter Change

    (NRPNs/Knobs/Wavetables)

  o support for dumping ensembles via SysEx

  o the SysEx structures are now completely documented under

    doc/mbsidv2_sysex_implementation.txt

MIDIboxSID V2.0 Initial Beta History (RC13)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   o created patch structure for Lead engine

   o removed old sound engine, the new one will be built up from scratch

   o overworked control surface handler - now we can control left and

     right SID channel separately (or together)

   o press and hold LINK button to select the SID channel (left/right) with GP button #1

   o this menu also allows to send a patch via SysEx

   o new patches can now also be received - this is important during

     development phase to store/restore sound patches via MIDI-Ox

   o Portamento effect implemented - "normal" and "constant time glide" CTG

     CTG can be selected in the OSC menu (PMd item)

   o A third portamento effect implemented: Glissando (PMd item: "Gls")

   o SusKey and Legato implemented (-> CFG menu)

   o LFO implemented - in addition to Sine/Triangle/Saw/Pulse/Random

     now also "Positive" Sine/Triangle/Saw/Pulse is available - they

     can be inverted with negative depth

   o menu items with toggle function now never go into "entry" mode

     where parameter has to be modified with datawheel - this is for

     faster usage

   o implemented modulation matrix:

     - there are 8 modulation paths

     - each path has two sources: ENV1..2, LFO1..LFO6, Constant 0-127 - much more will be added later

     - an operation parameter is available for each path:

       SRC1 only, SRC2 only, SRC1+SRC2, SRC1-SRC2, SRC1*SRC2, XOR, OR, AND, MIN, MAX, 1<2, 1>2, 1=2)

     - a depth parameter is available for each path

     - paths can be routed to Pitch Voice 1/2/3, Pulsewidth Voice 1/2/3,

       Filter and Volume of left/right SID separately

     - in addition they can be routed to 2 individual targets

       LFO1-6 Rate, LFO1-6 Depth

       More (e.g. ENV parameters) will be added later

     - Target 1/Left Channel and Target 2/Right Channel subpath can

       be inverted for simple stereo effects

   o added pulsewidth as modulation target

   o ENV implemented - it provides the parameters

     Attack1/ALevel/Attack2/Decay1/DecayLevel/Decay2/Sustain/Release1/

     ReleaseLevel/Release2 + Curve for Attack/Decay/Release phase

   o added filter as modulation target

   o filter of both SIDs now calibratable, settings stored in internal EEPROM

   o mod matrix + meter display working

   o init patch function implemented (press & hold LINK button)

   o random function implemented (press & hold LINK button)

   o added LFO Rate and Depth as modulation target

   o the sound won't stop anymore if a note is played during the

     patch is changed/initialized/randomized - instead, the new sound

     will be played

   o support for slave SIDs (access via MBNet)

   o new operations: 1<2, 1>2, 1=2

   o added Volume 1/2 as modulation target

   o Note, LFO and ENV delay implemented

     LFO delay and phase only takes effect when sync flag set (not freerunning)

   o LFO oneshot mode implemented

   o implemented global clock generator

     Since there is no free timer resource, it's realized as a clock

     divider, which is incremented on each update cycle (819.2 uS)

     A clock event will be trigger each time the clock divider value

     has been reached.

     Div=1 -> event all 1*819.2 uS

     Div=2 -> event all 2*819.2 uS = 1.6 mS

     Div=3 -> event all 3*819.2 uS = 2.5 mS

     etc...

   o optionally the clock generator can be used as MIDI clock receiver

     (Mod: Slv) - the MIDI clock can be divided as well

     Div=3  -> event all 32th notes

     Div=6  -> event all 16th notes

     Div=12 -> event all 8th notes

     Div=24 -> event all 4th notes

     etc...

   o "Mod: Auto" not implemented yet - should switch automatically to

     slave mode when a MIDI clock is received

   o implementation of Arpeggiator has started

     it is located in a separate menu now

     each voice has its own arpeggiator with own parameter sets (!)

     it's clocked by the global clock generator

     Spd divides the global clock again

     GLn (Gatelength) defines, at which clock between 1 and Spd the

       gate will be released

     Rng defines the octave range

   o Arp: added Up/Down/U&D/D&U/UD2/DU2/Random direction

   o Arp: added Sorted mode

   o Arp: added Hold mode

   o Arp: added "sync divider" mode

     - if disabled, the clock divider will be reset with a new chord, so

       that the arp starts immediately - perfect for live playing

     - if enabled, the clock divider won't be reset, so that it is always

       in synch with the global clock generator - perfect for MIDI slave mode

   o "Constant Arp Cycle" implemented

   o Velocity, Aftertouch, PitchBend, Keynumber, Knob #1-5 now

     available as modulation source

   o Knobs controllable via CC

     - Knob #1 assigned to CC#1 (ModWheel)

     - Knob #2-5 assigned to CC#16-19

   o Modulation parameters for Knobs (and Velocity=K#V,

     Aftertouch=K#A, PitchBender=K#P) are set within the Min/Max

     boundaries, which can now be edited in the new KNB menu page

     Note that sweeps from -128..127 and 127..-128 (swapped) are

     provided

   o Knob#1-Knob#5 now controllable directly from the CS Step C

     with the 5 rotary encoders of the oscillator section (select

     "Assign" layer)

   o removed "Balance" parameter, as it is redundant

     Can be realized with:

     MOD SRC1:K#1 In1:*, In2:o, Dep:127, Vol: L/R

   o support for AOUT/AOUT_LC

     - offset values (12 bit, 000-FFF) can be configured in new EXT menu

   o note: EXT (external) could also be read as "extension", because it

     the 12bit values could also be used for different purposes ("custom

     values")

   o implementation of trigger matrix

     It consist of 16 sources and 24 targets

     Sources are:

       Note On, Note Off, ENV1/2 Decay Phase, ENV1/2 Sustain Phase,

       LFO1-6 Period, Clock, Clock/4, Clock/16, MIDI Start

     Targets are:

       OSC1-3 L/R Gate (6 targets), ENV1/2 Attack, ENV1/2 Release,

       LFO1-6 Restart, Wavetable 1-4 Reset, Wavetable 1-4 Step

   o Trigger matrix connections can be configured in new TRG menu

   o Note that old patches have to be adapted the following way:

       - Note On: all 6 gates and ENV1/2 attack phase have to be assigned

       - Note Off: all 6 gates and ENV1/2 release phase have to be assigned

       - MIDI Start: ENV1/2 Attack and LFO 1-6 have to be assigned

       - the formerly LFO sync flag has now a new location in the trigger

         matrix. It has to be assigned in the Note On source. This can

         also be done from the LFO menu (shortcut for this TRG matrix connection)

   o Example 1 - LFO Chain:

     Assign all LFOs to OSC Pitch

     All LFOs in Oneshot Mode

     Use different LFO rates and depths

     Enable following Trigger connections:

        Note On->L1

        L1P -> L2

        L2P -> L3

        L3P -> L4

        L4P -> L5

        L5P -> L6

        L6P -> L1

   o Example 2 - ENV Retrigger via LFO1:

     Assign ENV1 to OSC Pitch

     Disable the Note On -> E1A connection

     Enable the LFO1 -> E1A connection

     Try different LFO1 rates and ENV A/D/S rates

   o Example 3 - Note Retrigger via LFO1:

     Enable the LFO1 -> O1L and O1R connection

     Try different LFO1 rates

     Try different OSC ADSR values (e.g. A=8, D=5, S=0, R=0) - remind the ADSR bug! :-/

     Try also different Delays between Left and Right SID

   o Example 4 - Simple ENV loop:

     Enable the E1S -> E1A connection

     Now ENV1 will loop between the attack and sustain phase

  o new button functions:

      - Link button now controls SHIFT function (and displays CFG page)

      - CC button now used as Page Up function (increments OSC/LFO/ENV/MOD/TRG/KNB depending on menu)

      - Edit button now used as Page Down function (increments OSC/LFO/ENV/MOD/TRG/KNB depending on menu)

      - Page Up/Down + datawheel (main encoder) allows to change the page via encoder

      - CC can be activated by pressing SHIFT+CC

      - Edit can be activated by pressing SHIFT+EDIT

      - SHIFT+E1/E2/L1..L6 button branches to the Envelope/LFO menu

  o SHIFT button now increases the speed of rotary encoders

  o added phase offset synchronisation feature

    Phases of the oscillators can be shifted in 0.4% steps!

    There is only one global phase available, which can be configured

    in the OSC menu. If != 0, the value specifies the phase offset

    between OSC1->OSC2 and OSC2->OSC3

  o added F2A (Filter to AOUT) function which allows to forward

    CutOff/Resonance to 4 AOUT channels (assignments are defined in setup_*.asm)

  o implemented knob parameters:

    - list of parameters can be found in mbsidv2_parameter_chart.txt

    - note that some parameters are not really suitable for live

      control - the table has been prepared for the WT handler, which

      will use the same parameter set

    - two different parameters can be assigned to a knob

    - the LCD shows the parameter in long format when the assignment is changed

      (selecting the item with a button does not already show the long format.

       I tried this, but the behaviour was too confusing... - you need to move

       the encoder to see the purpose of the value)

    - the handler automatically scales the knob value to the range of the

      target parameter. Regardless if a 4bit or a 12bit value should be controlled,

      the whole knob range from 0..255 will always be used

    - in addition, the knob range can be scaled a second time from a

      min to a max value

    - The formula:

         resulting parameter value = scale1(scale2(knob value))

      where scale2() scales over the specified min/max range

      and scale1() scales over the parameter range

    - Sounds confusing? Try this: Min=104, Max=152, Pa1=36 (Transpose OSC123)

      This will modify the 7bit value transpose from -12 to +12 notes

      (*2 because it's transposed from a 8bit value)

      Resp.: 128 +/- (2*12)

    - note that knob changes are non-destructive!

      This means: changing a parameter will not change the original value.

      Accordingly the value visible in the CS menu will stay the same.

      This is especially required to ensure, that changes made with knobs

      are really temporary and won't be stored with the "patch save" function.

    - OSC/Filter parameter changes are always applied on both SID channels.

      Offset calculations are done separately

    - TODO: "reset original value" function, accessible from the CFG menu,

      to remove the offsets from the original parameter values

  o implemented wavetable handler:

    - there is a WTC (Wavetable Configuration) and a separate WTE

     (Wavetable Edit) menu for easier navigation

    - it is possible to jump from WTC to WTE and back (last menu item)

    - WTC provides four different wavesets.

      You can specify a parameter, SID L/R, Speed (Clock Divider for

      clock events coming from the trigger matrix),

      begin, end and loop position (with optional oneshot mode) within wavetable

    - WTE allows to edit the wavetable like known from MBSID V1

      Even Notes and ARPs can be played :)

    - WTE value display can be changed between Hex/Dec view

    - wavetable values are forwarded to MOD matrix as additional sources

    - the wavetable pointer can be optionally controlled from the

      modulation matrix. For this, the "MOD" flag has to be set in

      the WTC menu. In this mode, the clock divider and loop pointer

      don't play a role anymore. WT1-WT4 are available as modulation

      target, the pointer is swept between the begin and end range.

      Try to control the position with a LFO or an Envelope or the

      velocity, and have fun! :)

  o there is now a new random generator menu which allows to randomize

    different sections of a patch separately

  o LFOs and ENVs can now be synchronized to the global clock (CSn flag)

    This clock is quadrubled to achieve better resolutions when it is

    synchronized to MIDI

    With Div=3, the LFO/ENV will be clocked 4 times for each 32th note,

    8 times for each 16th, 128 times for each measure...

    There are predefined rates for MIDI clock synchronisation, which

    can be selected in the LFO page when CSn is enabled

    They are starting at rate=245:

    64/1, 32/1, 16/1, 8/1, 4/1, 2/1, 1/1, 3/4, 1/2, 1/4, 1/16

  o BankStick support

    a 64k BS can store 127 patches, a 32k BS only 63 patches

    The BS size will be detected automatically during formatting

  o a "detune" parameter has been added to the CFG menu. It

    modifies the finetune of all oscillators

  o added GAE (gate always active) function - once set, the gate

    will never be released anymore. Instead, the voice volume has

    to be lowered externally or with a filter

  o added ABW (ADSR bug workaround) flag

    It adds an additional delay before the gate is activated.

    During this time, the ADSR registers are zeroed to ensure that

    the envelope has reached its final level before it will be

    triggered again.

    If you still notice ADSR hickups with a special configuration,

    just increase the ADSR delay in the OSC menu

    Note that the delay needs to be compensated from your sequencer.

    This feature is experimental and not suitable for live playing

  o the Env Ctrl button doesn't change the menu anymore

    so that the 5 rotary encoders of the ENV section can be used to

    change the currently visible menu items on a more confortable way

  o added V2A (Volume to AOUT) function which allows to forward

    the modulated volumes to 2 AOUT channels (assignments are defined in setup_*.asm)

    The internal volume is set to maximum if the V2A switch is enabled

  o added ARP oneshot mode

  o pitch (controlled by pitchbender) got a special parameter number: 80 dec, 0x50 hex

  o slave cloning function implemented

    press and hold the MENU button during boot to transfer the firmware

    of the master to all slaves via the CAN interface

    This procedure takes ca. 30 seconds, some messages will be print

    on screen (if not, something is wrong with the MENU button detection -

    please inform me in this case)

  o preparation for multiple engines: separated SID_SE and CS_MENU_TABLE parts

  o started with multi engine

  o implemented ensemble functions, so that different channels and

    keyboard splitzones can be assigned to multi channel instruments

    an ensemble contains for each master/slave MBSID:

    - Bank/Pattern/Flags (like V2A, F2A)

    - Global Clock Generator settings

    - Filter calibration values (Min/Max) for left/right channel

    - the setup for 6 instruments (channel, splitzone, transpose)

  o the new ensemble menu page can be entered from the main menu:

    - press the leftmost select button below the LCD to enter ensemble menu

    - press any other select button below the LCD to enter the patch menu

  o up to 128 ensembles can be stored in a BankStick (only 32k allocated,

    so it doesn't matter if a 32k or 64k BankStick is used)

  o first beta release :)

  o there is now a S&H (Sample & Hold) operator available in the

    modmatrix which samples SRC1 whenever SRC2 changes from a negative

    to a positive value

  o an incoming patch or bank change request doesn't update the

    the patch anymore if it was already selected before. This is to avoid

    "glitches" when a sequencer sends a program change shortly before

    a note is played.

  o the "Knobs" are sending CC values now when the CC function is

    activated (press SHIFT + Page Up/CC Button to toggle this mode)

    Other parameters are still not sending CCs over MIDI, as NRPNs

    are not implemented yet (low priority)

    The CC numbers are 1 for Knob #1 (Modulation wheel), and 16/17/18/19

    for Knob #2-#5 (GP values)

    In addition, Knob #P sends Pitchwheel Events in CC mode

  o support for analog inputs (J5:A0..A4)

    This feature has to be enabled in the setup_*.asm file by setting DEFAULT_J5_FUNCTION to 1

    Conversion results of the analog inputs are directly passed to the knob handler.

    This generic approach has the advantage, that it is possible to control 5*2 parameters

    within a specified Min/Max range, and that in addition the analog values are available

    as modulation source within the modulation matrix (K#1..K#5)

    The feature behaves differently on master and slaves:

    Master: analog inputs are forwarded to the selected SIDs - use this

            option as replacement for rotary encoders, or for adding

            analog control elements like pots/faders/joysticks to your CS

    Slave: analog inputs are only handled internally - use this option

           for modulation with analog signal generators

  o added "Notes Off" function to the SHIFT page (replaces Random

    function which has a separate menu page anyhow)

  o implemented bassline engine

  o support for AOUT_NG module

  o integrated support for ASID protocol, which has been originally

    developed for the SIDstation to replay .sid files.

    (see also http://www.midibox.org/forum/index.php?topic=2038.0)

    Only the master core (Device ID 00) will play SID tunes!

    Nice visual effect: the LED matrix of the CS shows three animated

    meters whenever a gate flag of an oscillator is set.

    SID player mode is automatically enabled once an ASID stream is

    received. It can be exit by stopping the player on the PC, and

    pressing the MENU button

    Unfortunately it turned out, that there is currently no SID player

    available which can replay .sid files properly via MIDI.

    - SIDplay (http://www.d.kth.se/~d93-alo/c64/spw/sidplayw.html)

      Perfect integration, but plays tunes too fast under WinXP.

      Works fine under Win95/Win98/WinME. Not tested under Vista

    - ASID (http://www.sidstation.com/sidsupport.php)

      Crashes under WinXP once the tune should be played

    - ASID XP (http://www.sidstation.com/files/asid_xp_1.0.zip)

      Tunes played correctly, but the MIDI stream is corrupted at

      the very beginning when the player is started. Accordingly the

      sounds are not properly initialized.

    Workaround: start a tune with SIDplay (for proper sound

    initialisation), thereafter play it with ASID XP

  o resonance now editable with 8bit resolution (only applicable for F2A option)

  o implemented global BPM generator, which replaces the global clock divider

    for more consistent clock handling

    Now it doesn't make a difference anymore, if MBSID receives a

    clock at a certain BPM, or if it generates it internally

  o support for sustain CC#64 (if CC value >= 0x40, notes will be

    held, with CC value < 0x40, notes will be released)

    Currently only supported for lead engine!

  o drum engine implemented

  o meter mode now also supported for multi/bassline/drum engine

  o superpoly function implemented for lead engine (experimental!)

  o various improvements for drum sequence editing:

    - cursor now controlled with encoder

    - the "<" function has been replaced by a rotate function, which

      allows you to scroll the pattern left/right

    - the ">" function has been replaced by a direct shortcut to

      the DRM menu page - the instrument number will be set

      automatically according to the selected track

    - the mod target buttons (named with E1/E2/L1/...L6) now

      change to the track editor, and select the appr. track (1-8)

  o implemented MIDI Clock Master/Slave Auto Detection

  o bassline/drum sequences now stopped when a MIDI Clock Stop

    event has been received

  o bassline/drum sequences now started when a MIDI Clock Start or

    Continue event has been received

  o improved "play button" function (e.g. only selected instruments

    played, selected drum is triggered, etc...)

  o support for "Sync" button (it just jumps into the ENS->CLK

    menu for Master/Slave/Auto mode and BPM selection)

  o support for full parameter access via NRPNs

    see mbsidv2_parameter_chart.txt for details

  o possibilities to select a patch:

      - moving datawheel in main screen (as before)

      - using Page Up/Down button in main screen and patch main menu

      - selecting bank and patch in the ENS->SID menu

  o possibilities to select an ensemble:

      - pressing MENU + moving datawheel in main screen

      - using MENU + Page Up/Down button in main screen

      - using Page Up/Down button in ENS menu

  o ensemble can now be initialised with preset (-> go into ENS

    menu, press SHIFT button, select "Ini.Ens" option)

    Note that Patch and Bank settings won't be touched by

    this initialisation!

  o there is now a new EXT page within the ensemble menu which

    contains following options:

       - F2A (Filter-to-Analog): was previously located in SID menu

       - V2A (Volume-to-Analog): was previously located in SID menu

       - Iv1..Iv8: inversion of output voltage at channel #1..#8

  o added optional FIP option (Filter Interpolation) which smoothes

    CutOff changes. It is especially useful when CutOff is changed

    via CC (-> low resolution) to reduce the steppyness.

    The option is not useful when the CutOff parameter is modulated from

    a fast LFO or envelope (on the other hand: it produces interesting

    effects in such cases ;-)

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

MEMO:

  - in Bassline mode, CCs could control individual knob parameters for

    left/right channel by using the "current" assignment, and selecting

    the instrument (L-, -R or LR) via different sets of CC

  - a solution has to be found for bassline mode, how values changed

    via knobs should be properly forwarded to the edit patch storage

    for consistent value sets

    As this method has advantages and disadvantages (e.g. destructive

    changes in the edit patch are mostly NOT wanted!), maybe a soft-option

    could be provided (but I'm sure, that most people would disable it

    quickly once they noticed the disadvantages)

  - There is currently a "Notes Off" in the Shift menu which allows to

    turn off all notes of the selected SID(s)

    For more comfort, it could make sense to send this command too all

    SIDs independent from the SID selection

    In addition, a "Note On" (Play) command could also be placed into

    the Shift menu - but where? (maybe as replacement for Init Patch,

    as a patch can also be initialized by changing the engine)

  - drum engine mode: additional parameter for WT table offset?

  - individual copy/paste/clr function for drum instruments?

  - individual save function for instruments (for all engines)

  - selection of bank/patch within same screen in ENS->SID->Bnk/Pat page

  - if multiple SIDs with different engines are connected, the

    performed CS modifications (button/encoder turns) can result into

    a big mess. A fix isn't so easy (easiest but inconsistent solution: the

    master has to remember the engines of SID1..4 in order to decide,

    if a parameter is allowed for beeing sent)

  - theoretically it could be possible to modulate 8 of 256 sound

    parameters (which are normaly only accessible via knobs, WT or NRPN)

    from the modulation pathes (e.g. envelope or LFO source) by providing

    a special EXT -> Par (AOUT Value -> Sound Parameter) routing.

    Since 8 EXT values are available with 12bit resolution, this should

    be sufficient for most cases.

    The AOUT option wouldn't be available in such a mode...

  - the external switches could be optionally triggered by notes, or

    maybe better: reflect the gate of ENV1 and/or ENV2 which is used to switch

    between attack/decay/sustain and release phase

    This would be a quite useful function for external ADSR generators

    Problem: which possibilities are really required, how should it

    behave for the different engines, how should it be configured? Within ensemble?

  - a switch which disables the menu jumping when an encoder has been moved

    has been requested from multiple users meanwhile

  - a switch which swaps the encoder speed selection: slow by default, fast

    if SHIFT button pressed

  - add Display the state of OSC1 arp on a custom LED

    (pendant to CS_MENU_BUTTON_Arp button function)

  - The WT "key" control feature could alternatively start a (short) sequence

    instead of only selecting a single WT position.

    This would allow to embedd multiple WT sounds (e.g. drums) into a patch,

    and to select them with the note number (especially nice for multi patches)

Starting with a completely init ensemble, init patch... turn on arp for osc 1, sort on,

This continues in a strange way if you add more notes:

dir down, range 2, play C3 E3 G3 A3 => loop { C3 A3 G3 E3 C4 A4 G4 E4 }   (wtf?)

anyway... I was expecting that the range parameter is always positive octaves, i.e. you will get the notes repeated with a +12 semitone transpose, and if you happen to play notes more spaced than 12 semitones then I wouldn't expect it to do anything fancy to avoid a sequence which is not an ordered "note number"

i.e. dir up, range 2, play C3 C4 C5 => loop ( C3 C4 C5 C4 C5 C6 ) no problem for me ;-)

but when using down direction and range > 1, shouldn't it be the exact inverse of what you would get for up direction and range > 1?

when using bassline seq, if i sequence a c, it will run the first pattern ok.

So on a 16 step pattern on the md, i put a c on the first step, and a 4/4beat.

But if i say to the md roll on now on the 2 first step by changing the pattern lenght, the bassline seq continue is run even if the c is retrigerred which could be a cool thing, but can too do some desync if in fact i don't tell the md to re-go to 16 step perfectly in sync. So is there a way to force the sid seq to began at the beginnig of the pattern each time the c is trigerred???
