Hi Linda, I asked Synthzone member friend Tapas who's at Naam right now, to please make a special stop at the Casio booth to checkout the WK-7500. He called me back to say it sounded like garbage, and nothing even remotely as good as the online video demos sounded. That said, this wk-7500 youtube promo never showed anyone actually playimg it live either. Deceptive promotion perhaps? Interestingly enough, symthzone member, Kabinosus, recently posted a similar very negative reaction as well, after having just auditioned it in a musc store.
