Trident, you are right the Roland Orchestral piano is good, but guess what?? The Roland Super Quartet is the best of the Roland soft synths..
Yesterday I tried the Casio WK3700, I couldn't tell any big differences over the WK3000 sounds..I was listening from memory, and did not have a WK3000 to compare at the store..

I did run across a style Jazz Combo3[I think] ..it seemed a little different than Jazz Combo on the WK3000..Very usable..

Jim , I am with you on the lack of mid range in the piano sounds...That is why I liked the Roland E-600 piano..

Guys,[KN guys] I think it is just what we get use to...I don't think the KN7000 piano is at the top of the list...I seem to recall a lack of dynamics with the tone/fullness[not loudness]..

There are many good piano sounds on our keyboards, tone wise, but across the board[range] is when they start telling the short comings..
