Yes, Bill, I can see how that would work. I do have several song setups where panel memory buttons choose different built in rhythms and composer rhythms, as well as voicing, at different places of the song or medley. I have 24 panel memory buttons to work with, and usually progress through them with a foot switch. But, I don't remember any that use totally different styles on the fly. My routine is to do a custom copy and move any custom style rhythm that I might be using to the composer, before I save to SD.
