That was a good attempt Wilkes, but not exactly. I am aware of the key mapping, but on my SC880, you can set two parts to the same MIDI channel and map them to different key zone. This differs from our XP's [LAYER] mode which will let you set some parts to one channel, but then you can't play the other [PARTS] individually.

The reason I would want to do this is so I could map a whole drum kit using parts 1 & 2 for example and play the combined kits on channel 1 & 2, since they would be on the same channel, I would be able to play them at the same time from the board.

Then I would use the remaining parts to build up a sequence. [Part 3] could be the trumpet and [Part 4] the Bass. It just sucks that because you use the crossfade parameter in a patch to map two tones to one key, that I have to lose the Toms or the Cymbals, Because of that, I can't play it like a full drum kit.

I think the only other option I have is getting a used Roland Octapad. The pads can individually be set to ANY channel and from there I could play two seperate channels at once with out having to go to Layer mode.

Any other suggestions guys?
