My issues with the WK-7600 are no MIDI, and no control for chord memory or "sync stop." Once the style starts, the only way you can stop it is by triggering an ending, fade, or stop the style cold. I can't understand why this basic feature was omitted. Also the keys don't appear to be durable. I have seen a few of these with keybed failures in my local music store. Yamaha's entry-level models appear to be better built.

Casio KNOWS how to build a good arranger, but so far they haven't matched their effort of a decade ago with the MZ-2000. We'll see!
