The FTP can't really work this way. It loads a new patch, and while doing it, it wipes out the previous one. Also, the patch changes are not instantaneous. If this is wrong, please correct me, but the one I tried couldn't do it. You pick a sound and play it. Then you pick another one. It was really set up with recording and transcribing in mind- and possibly playing live with a set order of sounds. I don't work this way, so I don't yet think the FTP will work for me. I hope someday it will, but right now the live use is a little clumsy.
