Disklavier

I have copied both the original audio CD as well as the
companion PianoSmart floppy disk on my computer, and
they both work on all the DKVs I have tried them.
Although I have not tried the following experiment, I
really think it will work - I plan to take some MIDI
file, render it to a wave file and "burn" it to a CDR,
then record a PianoSmart accompaniment to a floppy
disk.  I expect it will work just fine.  As I have said
before, this is not all that hard.  Audio CDs have
track identifiers with digital readouts of the exact
times they appear on the CD.  PianoSmart uses the MTC
(MIDI time code).  When you put a CD into the Yamaha CD
player, then put in ANY floppy disk into the DKV with
PianoSmart, it will try to register the floppy with the
CD.

I once copied a software program CD and used the
holographic numbers near the hole for the "key" and it
worked!

What does NOT work with PianoSmart are audio CDs with
copy protection schemes on them.
