Hello everyone. Here a new happy user of an FM9. For solos in songs I need to assign a button to simultaneously switch channels A and B on the AMP and A and B on the delay, which is what I normally change for soloing in my presets. It doesn't work for me to make a solo scene, as I use basic clean and dirty presets with various scenes of specific effects, so I need to be able to switch from channel A to B of the AMP and DELAY, and thus I would switch between rhythm and solo in ANY scene
