Yeah it would be nice to have 4 variations. The 6 tracks don't really bother me too much, but of course more is always better. I think the board greatly needs the ability to record user styles. Just the ability to loop and overdub drum/bass/chord/pad parts would be great. That would then open up the other 6 tracks for solo work.

However, given that Casio has increased the number of sounds and styles (and improved the sound quality), and added more user sample memory without jacking the price is more than enough for this model. With those additions they could have easily jacked the price another $100.00 The 3700 will be sitting in my home before Thanksgiving I'll probably keep my 3500 for a midi controller or just an extra board.
