I have a Roland KR977 digital grand piano.  It has a pretty good piano, but I also like the electric piano sound and with the hex chorus.  
 
I called Roland to ask about a soft synth version of the tone generator in my piano.  They said cakewalk partnered with them to take over the soft synth market.
 
I know there is a Roland Sound Canvas soft synth.  Is there a soft synth for the KR piano series sounds?  Are the sounds in any existing soft synth by Cakewalk?
 
Particularly, I like the epiano sound (not a standard rhodes or Dx7 sound) and it sounds good with the hex chorus built into the KR977.  It's very expressive with the Kr977 keyboard.
 
Thanks
