Hello. My goal is to have three voices (performance mode) layered on the keyboard and the fourth controlled by the Roland PK-5 foot pedal, presumably on a different MIDI channel. I’ve made myself crazy trying to make this work with Master Mode. I could make this a fourth part in the performance and limit the keys, but that will take away a part of the keyboard I need for one of the other parts. As sophisticated as this keyboard is, I remain confident this is possible, but I can find nothing that speaks to it. I did have an excellent article on Master Mode bookmarked that might have led to a clue, but it seems to have been removed forever.

Any advice or hint in the right direction is greatly appreciated!

Giant thanks in advance!
