Well, still can't take this to work until the audio ins work, but listening at home has confirmed that Korg really did a major upscale to sound and styles. They smoothed out a lot of rough edges, the backing patterns are so much more logical, but still have that Korg punch. Variations progress in a less frantic pace (much like Yamaha) The drums are Sooooooo good - sound like live kit. I get happier every time I touch it.
