It takes awhile to get use to, but if you're willling to learn it - all the better. I've never ran out of polyphony and the keyboard action is excellent.
Effects are good and somewhat easy to use.
As far as factory extras, all you're going to get is some cheesy programs disks and some OK but limited style disks. Midi capabilities are all there and the pressure sensitive great. Only accessable through backing tracks. I would have spent the extra bucks for a true sequence for the i3 or a Roland. Anyone, I'm so ashamed to have this great potential of a keyboard that I don't let anybody know that it bit the big one.
