Flash RAM is going to change the game, albeit expensively, but Yamaha are still locked into their own
proprietary multisample format, no Akai import or Soundfonts etc., so the choice you get to fill it
will still remain in Yamaha's (so far) miserly hands. It is LONG past time Yamaha opened up their samplers
(Motif's have the same problem) to the largest sample collection out there.
I beleive the XF allows you to import samples and soundsets from your favourite VST's.
Can't those be tranformed to T4 format (if it isn't allready the same)
