Switching channels on Marshall JVM 410H using Midi;
Newbie here, I have searched other posts but can’t find what I need. I want to use my shiny new G System to switch between the 4 channels on the amp. I’m sure it can be done, and I’ve used a Tech 21 Mini Mongoose successfully with the amp so far. However, although I can get the G System talking to the amp I can’t get it to store and transmit the right commands consistently.
Any help very gratefully received!
