Disklavier

In using Yamaha's XG works, the instructions for using the Voice to Score 
function (p.24) state that this feature  only sort of works, and that any 
harmony will make it work even poorer.  It is clearly a monophonic wave to 
MIDI converter.

It is a lot easier to convert a monophonic audio wave to MIDI than a 
polyphonic wave to MIDI.  Monophonic audio is just one voice; i.e. singing, 
a flute, a guitar, etc.  Polyphonic wave files have more than one voice, 
like someone singing with a band accompanying them, or an orchestra playing. 
  As for piano playing, it more or less falls into the polyphonic category 
because of all the partial harmonics generated.  If you play the C below 
middle C, and record the audio, then convert it to MIDI, your piano would 
probably play the C below middle C (the note you played) as well as middle 
C, middle G and the C above middle C.

Thanks for pointing out this feature in XG Works!
