… I want to load a bank for each song via MIDI, and load variations for that song via the three H90 switches. Is this possible?
Does your MIDI device send MIDI CC messages? If so, I see a way using the Global Mapping Chart.
One CC (value 64-127) to Enter Back Mode, if needed. A pair of CC mappings for Bank Up & Bank Down (values at 64-127). Perhaps one more if you want to exit back out to Select Mode. Some combination of those – plus the 3 onboard switches – should get you there.
Mappable in the pedal System – MIDI -> Global Ctl , or the larger overview in H90 Control -> System -> External Control.
