There are several softwareprogs to convert audio to midi
on the market, but they usually don't manage to do a proper
convert of more that one single voice at the time.
If you play a clean flute or piano etc, it's possible, but
there are no success with a music piece of many instruments
at once at the moment, at least as I have heard about.
