MusiCo,
Well, mostly orchestrial sounds. And all Piano types. Strings are important to me, especially solo violin, cello.

I guess really the solo violins, strings, clarinets, sax, flute, oboe, all horns (I especially like french horns), upright bass, and all other orchestial stuff. Also, other sounds used in solo meleody.

I could care less if they took all the synth sounds out. Well, maybe that's an exageration.

I will be concerned about the sample quality, consistancy of sound and vibrato note-note on the entire instruments range. I will also care about the keybed feel as compared to my PA2. Even though that will not be a killer as 61 is not enogh for me and because of Yamaha's stubbord ness! I will have a 76 note MIDI board under it.
It sure will be interesting.
