I do have the ins definitions for the QS6.1, although I'm not sure where I found them. I think you may be able to download them from Cakewalk's website.

A few other things come to mind...Make sure that GM mode is "OFF" in order to make bank changes on each track. And make sure MIDI Program Select is set to "ON."

Don't know if that solves the problem, but the tech support people at 800-5-ALESIS may be able to help as well.
