OK - this is a weird one....
Any effect I put on the left channel (input/side), I can control via midi (in this case on/off). Any effect I put on the right channel (input/side), when I assign the controller, it "registers" and displays that Midi channel #26 is not assigned. However, the effect parameter (in this case on/off), doesn't change when I send the signal/press my controller.
I can move any effect to the left side and it works just fine. Move it back to the right side and it doesn't.
Also, MIDI controller #70 or #71 will randomly assign when I'm trying to add. There's no midi #70 or #71 with my setup. I have figured out how to trick the system when using the MOD interface (I put a pedal on the board and just let it assign to that pedal, then its "used" and won't get assigned).
Any idea what I'm doing wrong?
Thanks!
