Chas , I understand what you are saying...personally I think you are playing the weakest of the group..namely Triton and Motif...Try the RD700sx or the SRX card[SRX11..I think]..I think these are the best without going VST..Pergatory.com[piano test] will show you....

I also find a lot of acoustic pianos do not sound as good as some Roland pianos

BTW: Why did you guys ditch Hawaii and come back?...I have friends that moved there, and never returned....
I am looking for a good family in Hawaii to send my wife there...
