I agree in "the right road" remark Squeak. Even if I am nowhere near creating my own styles, and I just play for myself, (or make quick 4 note polyphony covers for my mobile)I liked the sounds (of course), I liked the layout of the various keys, (thank god the style variation keys were BIG) but yes, the "pops1" or "rock" something style is IDENTICAL to the No 027 style in the decade old CTK that I have. Others were too, I just don't rememeber their names
Anyway, as it was noted in a post here long before the HD crash, they (casio) seem not to be really interested or strategically looking into producing mid or high end keyboards. Everyone here says MZ was a right step but they just stayed there.
I'd drool over a 4 intro/variation/ending, more styles, USB quipped WK-4000.
Though I never got to play it, the key touch of the MZ on display felt different than the WK, the WK was a little stiffer. I liked it.
thanks for taking the time to read my posts.
