Confusion re: Sending SYSEX with L=1, L=2 ... L=16 to Access Virus C 'Multi' - MIDI Designer Q&A

Confusion re: Sending SYSEX with L=1, L=2 ... L=16 to Access Virus C 'Multi'

Controls MIDI Targets from: Other/Unlisted Maker
The quick question is: Is there a way to send 16 channel strips using their 16 respective MIDI channels (1 per strip) from MDP2 to my Virus C?

I'm putting the 16-track Virus C "Multi" mode to use on my Virus C. I intend to set 16 channel strips in a MDP2 layout which uses a host of SYSEX commands. These commands needs to be segregated to their respective MIDI channel. I'm designating L=x to each of the 16 midi channels.

The problem is I'm only able to control CH1 on the Virus C no matter what L is set to in MDP2. No matter what MIDI channel a channel strip's items are set to broadcast, the Virus C only responds to Channel 1.  I checked MIDI Monitor to ensure the respective MIDI CH is transmitted and it's not showing any channel but the L value is indeed being transmitted at the end of the SYSEX string.

JK to confirm but this is a known hug. What's the simplest possible configuration for me to reproduce the bug and prove when I have a fix?

MDP2 is sending the SysEx as programmed, but the board is not responding?  Relook at the Virus SysEx definition to see how you access the different parts - maybe the digit after the 7x.  SysEx is not "channelized" messages - you cannot arbitrarily append a channel value at the end.

Good heavens you are right. I missed the forest for the trees on this. Indeed the Virus manual discussed this and I completely forgot it is handled a different way. I'll come back with a breakdown for anyone's future reference once I get it nailed down. Or you can delete this question since I was operating on a flawed premise.

NP.   Not knowing the Virus, but a quick look at the manual, I suspect that the correct SysEx string is 00 20 33 01 00 72 L 20 V.  Looks like valid values for L are 00-0F and 40.  You can get the 00 .. 0F 40 using named ticks.

Indeed. It's working. Thank you.  00-0F are the 16 multi sections and 40 is in single mode.

Thanks Kenyon, rockstar as always. So there are no known bugs on sysex. Send right now?

As far as I am concerned it is working beautifully on VirusC multis. The issue was foggy brain on my part.

re: knowns bugs on Sysex - there are none on transmit.  The only bug is recognizing certain configurations of L and V on MIDI receive.  qa/9103 has the correct info.  The observations spreadsheet wasn't clear, now corrected.

Thanks, all clear now, much appreciated!
