Hi, so if you want to mute MSB 38, as you way, that would be MSB 37 for mute lp38. The way you have the NRPNs set for all channels is to set mute on when you release a button. Maybe you should set them for mute toggle? Maybe you have a soft button on your SQ5 set differently for those channels that may be interfering.
For Mute toggle from your controller, the message would be:
b1 63 00 b1 62 pp b1 b1 60 00
where pp is the MSB
I suggest you show your log window MIDI IN for CC5 and CC6 and also CC 37 and CC38 and compare the messages to see if your controller is sending the same format. (momentary vs toggle).
Also double check MIDI out to see if it getting the same message format. I see no reason that it shouldn’t if the incoming messages are consisent as the translator uses the same rules.
Otherwise, I can’t see anything wrong with the project file.
