If I understood correctly, you are searching for a digital piano. Well, me too... I posted here a request for informations, and many answered me with good advices I will study. People pointed me on the Yamaha Clavinova (which I can't buy, it costs too much for the quality I'm searching for and it's too big), the best models are very good but at a high cost: the Kawai P9000 (or MP9000, now I don't remember well) and the GEM PRO-2 are similar, but someone preferes the Kawai action.

Actually I know a bit about the GEM PRO-2: it has weighted action, 128 oscillators (128 voices) and 64 performances (voice-effects combos), a two-tracks, 45000 events sequencer, 64 built-in sounds with acoustic and electric pianos, organs, strings and basses, a MIDI in-out-thru and a serial interface to directly connect to a PC (for sequence downloads etc.). Also, it can connect to a pedalboard to be better used as an organ, you can tune all the keys one by one, it has a graphic 7-bnad equalizer: GEM engineers implemented some physical models (sympathetic string resonance, natural decay of the notes due to key release and a 16-level pressure sensor for the damper pedal, which makes it possible to use the 'mezzo pedale' and so on). And much more...

AFAIK the PRO-2 (with the professional pedals) does the job, don't know if others do (but it's at least possible!): the best I can say is, try all electronic pianos you can find and buy the best for you. Actually I'm not very convinced about the action of the PRO-2, but all the other things are really good, so I must still search for other options.
