Don, understand you need more a turnkey system because of your busy schedule. This is one time I have to just study and set up things. Might never play out again ???

I am very interested in the audio function (the kid is coming back in me ). If it will do what I want, I would take it just for that. The "next up" loop would allow almost anything (different chords, etc).

I keep reading and will be ready for the board next week.

Thanks for sharing your findings and thoughts. I'll do the same in time.
