Thanks, I think you might have misunderstood tho’. Do you know of a way for instance that you can have the midi going from OT to A4, then midi thru from A4 to Prophet, having both synced to the OT but only the Prophet receiving midi note data? That’s my predicament, the microbrute is receiving note data but the 1st drum track of the AR is also receiving note data which I don’t want.
