Hi,

PSR900 (and 900 pro) has a expansion capatibility, and for example, onboard sampling RAM can be increased up to 65 Mb using pairs of conventional SIMMs.

I don't know if new PSR2000 has that capability also. If the answer is YES, will it open PSR2000's voices to the possibility of sounding exactly than PSR9000 -that has more MB for voices-? Then, will one of major differences between both kbs disappear?
