Anyone tried the prokeys 88 by m-Audio yet ? how is the action ? how are the sound samples (not just the piano) compared to other digital pianos like the Yamaha P-series. I like my P90 for the action and the piano, but now that i need decent strings, organs and rhodes, i'm disapointed in it. I don't want to always resort to a sound module when I would be fine with onboard sounds... but the rhodes espcially is to dry for me... i don't know how to describe it. Francis.
