Hello, just got my H90. Very cool despite my limited knowledge. 1. Can a program have the same effect on both A and B? 2. Can a CTL be configured for channel switching an amp? Thanks!
1). Yes. Series & parallel can give you wildly different results. Stacked, or isolated instances.
2). I haven’t tried it, personally. I could be wrong, but I don’t think it will do ‘relay’ switching. But if your amp accepts MIDI, I can see where you could ‘bind’ a switch to the amp with program or CC messages.
