I have a Marshall JMP-1, TC Electronics G Major 2 with an ART X-15 Foot Controller. Try as I may, I cannot get these devices to change correctly. If I press button one on the ART, It puts Marshall on channel 31 and TC Electronics on 3. I've read manuals, factory reset, read online...I'm at a loss!
marshall jmp-1 midi help?
