Bachus, this post was not aimed at you....or Steve, or Russ, or Sam CA, or any of the KNOWN pianists in the group; we KNOW why you guys want a great piano/(s); for the same reason these durn guitar players (sorry Russ, Nigel, Eric, John C.) HAVE TO HAVE 8 gazillion guitars; it's their PRIMARY instrument and they want as many options as possible. Although we welcome your replies, this was mainly aimed at those keyboardist for whom piano is NOT their primary instrument. I believe Fran's answer came closest to the truth; we hold the piano up as the 'gold standard' and assume that the quality of the PIANO voice will probably reflect the quality of the other voices in the instrument. In any case, very interesting responses and another opportunity to peek into the mind of that mysterious creature, the keyboard player (and his sub-species, the arranger player

).

Either your a piano player or a arranger kb player...
No matter how good the piano is in an arranger kb, module or whatever
if you play it in a MIX of other instruments like a style, sequence etc...you will most definitely lose the true nuances of the piano. IMO Piano should be play as such, a solo acoustic instrument so the player can express all their talents when doing so which is beautiful when done properly...and the Piano is then showcased as it should be.
But MIX the piano sound with the band, style, etc,....
it's just another sound within the MIX and no one can really hear it's attributes vs a solo piano.
