Disklavier

Good afternoon, everyone.

Carl, the standard Mark IV measures velocity on the normal MIDI scale  
of 0-127. All Disklavier Pros (from the Mark IIXG version to the Mark  
III and Mark IV), however, measure velocity on a scale of 0-1023. The  
extra bits of resolution are stored in various MIDI controllers  
(controllers which are otherwise undefined in the current MIDI spec).  
All of the extra MIDI data is transmittable over MIDI cables.

Regards,
