I have to agree with Jamman. Granted there may be a few acoustic instruments that one would like better on the DGX, or Casio WK, but the Korg N-364 is a good synth. It has much more in depth editing than you'd find on a Casio WK, or Yamaha DGX. Plus you get a full 16 track sequencer that allows you to loop and overdub, plus assemble a pattern track, Neither the DGX or the Casio WK will compare to the sonic quality of the synth sounds found on the N-364. Plus the N-364 is built for road use as well. It has a much more solid construction compared to the other models mentioned. Also keep in mind that the N-364 shares one thing in common with the WK-3000. Only one (1) insert effect can be used per performance and song.
