Kawai (like Yamaha and Casio) made too many similar models. This one features "dynamic touch" (velocity sensitivity) but lacks up and down arrows for easier access to sounds found on previous models. It also doesn't have MIDI and only a 1/4" stereo headphone output (in addition to built-in speakers).
