Ray, not sure why this is happening. How are you making CC assignments on the CS-80V? Are you using the MIDI learn function? i.e. cmd or ctrl-clicking the on-screen control. There are a few CC numbers that CS-80V reserves and can't be assigned. It's unlikely, but possible that you chose them. The reserved CC's are 0, 1, 32, and 64. Also, CC assignments are separate for each of the 8 voices in MULTI mode. For troubleshooting your problem make sure the MULTI hatch is closed. That's all I can think of right now.
