[ To the best of my knowledge the Disclavier system is only available

[ It is not available as an aftermarket system in the US. You probably
[ are thinking of the PianoDisc system from PianoDisc/MSR.
Well, just for the record it is Disklavier and Yamaha does
not sell a retrofit kit in the US. I've heard that they sell
one in Japan but I've never seen one. The Disklavier is
available on all Yamaha pianos, I believe. Well, I
should say, Yamaha starts with their regular pianos
and builds the Disklavier unit into them.
