thanks all. re the piano board: I haven't had the time to get too deep into it, but here are some answers:
the stereo pianos are marked as such. they're very different from the Live! Grand on the 9kpro itself -- there's a nice jazzish grand and several cool combinations, incl. one called Rhodygrand. of the pure pianos, none are as vivid (or reverby) as the Live Grand, but all are expressive.
the EPs expand greatly on the 9kpro's offerings -- there are several decent wurlis (alas, none that go as far as the Triton's VeloWurli) and a number of rhodes sounds, including the Dyno circa 1981 and 83. haven't gone beyond that, tho I did see a page loaded with clavinet sounds that looked interesting....
