Donny's right - the Korg is gone.
It has wonderful sounds and the best harmonizer on board, but there are some major shortcomings that I won't deal with:
1)Still can't go between seq and arr without stopping
2)sounds mute when changing certain settings
3)erratic drum fills still creep in
4)Heavy, heavy, heavy
5)no patterns in multi pads in original O/S
6)Touch screen dependant - ouch

It's one of the best sounding boards I ever had, but it just doesn;t have the playability ( buttons-wise ) that Yamaha offers. I wish someone woulld step up to the plate here, but so far .... I have to play what's out there. The 3k is OK, but just barely cutting it for me. Sigh....
