<H2>Supported features by MIDIbox SEQ V4</H2>

<P CLASS=INFO>MIDIbox BLM doesn't provide any intelligence to play sequences by itself, instead it only acts as a control surface enhancement for the host application such as <A HREF="midibox_seq.html">MIDIbox SEQ V4</A>. This means in other words, that all features are implemented at the host side.</P>

20
<P CLASS=INFO>Following BLM modes are supported by MBSEQ. You can switch between the modes by holding the SHIFT button while pressing an "extra column" button.
21
 
22
<UL CLASS=CL>
23
  <LI><B>Grid mode:</B> displays a 16 step view of the selected track. The usage depends on the parameter layer assignment:
24
    <UL CLASS=CL>
25
      <LI><B>Note Layer:</B> each 16x16 row will play a different note. The 16 notes per column are pre-selected based on the current scale (MENU+FX-&gt;Scale) to increase the octave range, and to simplify the entry of harmonic notes.<BR>
26
      <B>Important:</B> one note per step can be selected if the track only contains a single note layer (default). By adding more note layers in the MENU+Event page it's possible to select multiple notes per step for polyphonic sequences.
27
      <LI><B>Any other parameter layer</B> such as velocity/length/CC/PitchBender/Roll/Probability/etc.: each 16x16 column works like a VU meter.
28
      <LI><B>Drum Tracks:</B> each 16x16 row is assigned to a different note (drum instrument) as configured in the MENU+Event page.<BR>
29
          <B>Hint:</B> instead of drums you could also play a synth. Since each note can be predefined, you are able to create your own "scale" this way.
30
      <LI><B>Extra Column:</B> selects the track that should be edited. Push the button twice to mute/unmute a track.
31
      <LI><B>Extra Row:</B> selects the step view. Increase the track length to play more step views. Use loop mode or the section function to play only a single step view.
32
      <LI><B>Planned future enhancements:</B> pressing SHIFT+16x16 button should set accent, pressing SHIFT+extra row button should select the section that should be played
33
    </UL>
34
 
35
  <LI><B>Track mode:</B> displays a 16 step view of all tracks.
36
    <UL CLASS=CL>
37
      <LI><B>16x16 buttons:</B> set/clear a trigger.<BR>
38
      <LI><B>Extra Column:</B> selects a track. Push the button twice to mute/unmute a track.
39
      <LI><B>Extra Row:</B> selects the step view. Increase the track length to play more step views. Use loop mode or the section function to play only a single step view.
40
      <LI><B>Planned future enhancements:</B> pressing SHIFT+16x16 button should set accent, pressing SHIFT+extra row button should select the section that should be played
41
    </UL>
42
 
43
  <LI><B>Pattern mode:</B> displays the patterns of all 4 groups.
44
    <UL CLASS=CL>
45
      <LI><B>16x16 buttons:</B> each quarter directly selects the pattern of a group (up to 64 patterns per group)
46
      <LI><B>16x16 LEDs:</B> green: pattern is selected for next measure, red: pattern is played, yellow: pattern is selected and played
47
      <LI><B>Extra Column:</B> selects a track. Push the button twice to mute/unmute a track.
48
      <LI><B>Extra Row:</B> no function yet.
49
      <LI><B>Planned future enhancements:</B> pressing SHIFT+16x16 button should select the pattern synchronized to measure independent from the global "synch-to-measure" function.<BR>
50
            The extra row could select a song phrase (so that all 4 groups change to predefined patterns)
51
    </UL>
52
 
53
  <LI><B>Keyboard mode:</B> allows to play notes of the selected track "live".
54
    <UL CLASS=CL>
55
      <LI><B>16x16 buttons:</B> each 16x16 column will play a different note. Than higher the row, than higher the velocity of the played note. The 16 notes per column are pre-selected based on the current scale (MENU+FX-&gt;Scale) to increase the octave range, and to simplify the entry of harmonic notes.<BR>
56
      <LI><B>Extra Column:</B> selects a track. Push the button twice to mute/unmute a track.
57
      <LI><B>Extra Row:</B> sends a note to the transposer (starting from C-2, unscaled)
58
      <LI><B>Planned future enhancements:</B> pressing SHIFT+16x16 button should play&hold a note until the same column is selected again.<BR>
59
            Support for playing notes on drum tracks.
60
    </UL>
61
 
62
  <LI><B>Stop:</B> stops the sequencer
63
  <LI><B>Start:</B> starts/restarts the sequencer
64
</UL>
65
 
66
<P CLASS=INFO>Following extensions are planned for future releases:</P>
67
<UL CLASS=CL>
68
  <LI><B>Keyboard Recording mode:</B> live recording function
69
  <LI><B>Transposer mode:</B> direct access to all 4 Transposer/Arpeggiator busses
70
  <LI><B>Keyboard Split mode:</B> play two instruments with upper/lower half of 16x16 matrix (with reduced velocity resolution)
71
  <LI><B>Keyboard Track mode:</B> all 16 tracks can be played "live" with only a single velocity value. Will be nice for quick soundchecks.
72
  <LI><B>Loop mode:</B> all 16 tracks are displayed like in "Track" mode. By pressing one button the last step can be defined (restart at first step once this step has been reached). By pressing two buttons the sequencer will loop between the steps.
73
  <LI><B>Mixer mode:</B> direct control of CCs and program changes like in the MENU+Mixer page

<H2>Hardware and Connection to MIDIbox SEQ</H2>
78
 
79
<P CLASS=DESC>The MIDIbox BLM firmware is running on a <A HREF="mbhp_core.html">MBHP_CORE</A> module, and communicates with MIDIbox SEQ via MIDI. It's possible to add a third MIDI IN/OUT pair to the MBHP_CORE_STM32 module so that the original two IO ports can still be used for other connections.</P>
80
<P CLASS=DESC>Here a <A HREF="mbhp/mbhp_core_stm32_midi3_extension.pdf" TARGET="_blank">schematic for MIDI IN3/MIDI OUT3 extension</A>, here an alternative <A HREF="midibox_blm/blm_connector_mbseq.pdf" TARGET="_blank">schematic for a special BLM connector</A> which allows to power the BLM via a (strong) USB hub, or from the MBSEQ PSU (+5V/Ground connected to MBHP_CORE::J2, MIDI OUT3 connected to MIDI IN of MBHP_CORE module, MIDI IN3 to MIDI OUT of the MBHP_CORE module - take care for the polarities!)</P>

<H2>Virtual BLM16x16+X</H2>

<P CLASS=INFO>To establish the communication between MIDIbox SEQ and the BLM emulation, select an unused USB MIDI port (e.g. USB4) in the BLM application and in the MENU+MIDI menu of your MIDIbox SEQ V4:

94
 
95
<P CLASS=INFO><B>Important:</B> the BLM modes are normaly selected with the SHIFT button. Since it isn't possible to select two button functions with a mouse (if you don't own a touchscreen...), the SHIFT function can alternatively be activated with the space key of your computer keyboard. Due to an unsolved issue with Juce, you have to press any BLM button after startup to get the space key working!
