The purpose of creating PianoSoft Plus Audio CDs was to provide a  
simple medium for combining the MIDI data that drives the piano with  
real audio (singers and/or instrumentalists). The solution was to put  
the singers and instrumentalists on one audio channel of the CD and  
to encode the MIDI data as audio and place it on the other channel.

That scheme worked very effectively, and I don't believe that  
Yamaha's solution has compromised the MIDI data. In other words, the  
Disklavier plays the MIDI data in the same way that it would play  
MIDI data that is received over a MIDI cable.

Accordingly, there has been no need to try to change that scheme in  
the Mark IV.
