Yes, that's true for the CDs that have MIDI on one channel and audio on
the other ("PianoSoft Plus Audio"), but this thread is about the
"PianoSmart" system, in which the CD is a normal commercial audio CD and
the MIDI is stored separately on a floppy disk and synced to the CD
by the Disklavier control unit during playback.

Again, you're referring to the Pianosoft Plus Audio CDs. It *IS*
technically possible to decode and play these CDs on a PC; I have done
it for non-Yamaha (PianoDisc and Pianomation) CDs. I already gave your
contract programmer Dan quite a bit of advice on how to go about this
for your YAMplayer software (everything except the Yamaha analog MIDI
CD encoding itself, which you'll still need to figure out).
