Does anyone know the pattern?
The "Play Mode" parameter C122 that allows you to switch into multi mode is part of page C, which unfortunately means it's only accessible via SysEx, not CC.
The same applies to C105, "Multi Program Change".
It’s obvious that the PC number is multi number.
What are MSB and LSB set to for the multi bank?
After experimenting a bit with my sequencer (Squarp Hapax), I’ve confirmed that once the Virus TI2 is in multi mode, sending a program change with the number of the desired multi+1 (the Hapax clearly uses base 0) selects the multi.
I disabled Program Change in each of the parts of the multi.
Just for reference:
Virus TI - SysEx - The SysEx pages have changed compared to Virus A/B/C.
https://www.musiker-board.de/t…ysex-bei-virus-ti.317840/ shows the response from Access on how to switch between modes via SysEx on the TI:
f0 00 20 33 01 10 73 40 7a 00 f7 switches to single mode
f0 00 20 33 01 10 73 40 7a 01 f7 switches to sequencer mode
f0 00 20 33 01 10 73 40 7a 02 f7 switches to multi mode
73 is page D btw, for Virus A/B/C it was 72 for page C. The rest of the SysEx command is the same.
Tested the command with SendMIDI and it works as expected:
