You have to remember, I am not very technical and am totally looking for simplicity, but to my knowledge, so far, I believe you can create splits and have the ability to 'swap' them and you can layer two voices only.(If anyone knows differently, please jump in and correct me). I don't think you can do multitimbral setups, but again, I may be wrong. BTW, Ben Allan, who is on this thread is a very good source for questions on this board.
