Disklavier

Edmond,
       The module I purchased in 1991 for my MX100A was a DOM-30, it worked 
with both Clavinova pianos and  Discklavier pianos.  DOM stnads for "disk 
orchestra module".  This module plays and records only DD disks.  I believe 
it can only record 11 tracks (piano on 1 & 2, 8 additional voices and 1 
rhythm track).  I recently upgraded to a DSR-1.  If you are interested in 
adding a module to your piano you but don't want to spend $800 to $1300 you 
might consider making me an offer on my old DOM-30.  I still have the users 
manual and can include the MIDI cables that connect to the piano.  The DOM-30 
connects to an external audio system by way of RCA plugs.
