Last night I was downloading and checking MP3 files from
http://www.purgatorycreek.com/. This site is where anybody need to check it before going to waste his money on Yamaha, Roland or Korg, etc. I mean all models. Last night I really disappointed about their sounds. I think they sound terrible. The only sound near to a piano was from Kurzweil models but even those not comparable with a Virtual Piano like Reason. I am using Reason Virtual Pianos for almost a year with my old Roland Synth as a midi keyboard. But I thought these new DPs from Yamaha/Roland can do the same. I was wrong. And I made my decistion. As long as I can not have an Acoustic piano, I am going to get a DP with good action. Connecting it to my computer and using it only as a MIDI keyboard. No DP from Roland, Yamaha, Korg sound even like a piano.
I really wonder why they only don't insert a laptop Main board into their keyboard and acquire licenses from Reason? In theory, it is not possible to create real sounds using Wave ROM less than 500MB. These models are using 64MB wave ROMs at most. Then what you can expect?
