Cass,
Finally gave up on it? I have a store demo 900 and await a new in the box unit when they arrive. Maybe I'd be interested in working something out with you. I just wish I could get my hands on the G70 for a week to see how it goes.
I'm especially interested in the piano & harmonizer, not to mention the great Roland styles.
I just don't know how much learning curve and easy it is for live play.
