Thanks for your reply. I am running version 1.32b.

Next to PRG CHANGE in the CONTROL IN menu, I have selected BASE. It still doesn’t receive program changes from the MPC. It has no problem receiving note data whether from the sequencer or the pads, track mutes via CC, tempo changes, transport signals, all work fine.

I don’t know the MPC very well, so it could be something on that end, but I’ve shuffled through every menu and scoured the manual and still can’t find anything that’s causing this.

I’m about to go from scratching my head to gritting my teeth. :-/
