Thanks for your reply!
I think MIDI Channels are set OK, given that if i plug OT directly to poly Evolver, program change works.(i Know that changing bank is a bit problematic)
So i guess i’m missing something in the A4 global midi settings?
Could you please tell me how did you set it? Thanks a lot
EDIT: I’m starting to think that the midi thru port of my A4 is f*ked up…
