Hi MMD'rs,  I have the opportunity to buy a Yamaha Disklavier.
It is a MK1 with the disk drive and controls located in a separate
box connected by a lead.

My limited knowledge of these pianos is that the MK1 can only play
Yamaha disks and the later models play other formats, like MIDI files,
and I would also like to be able to play scanned rolls (via WindPlay).
Is this the case and is there an upgrade available ?

Regards
