Greetings -- This responds to John Farrell's posting on converting
audio to midi.  Here is a link to an interesting article about recent
developments in this endeavor:

Also see http://www.zenph.com/recording.html.  Zenph Studios reportedly
takes old recordings, converts them to midi files and then re-records
them using a Disklavier for playback.  Unfortunately, no samples are
posted.

I visited John's web site today.  I had forgotten how excellent it is.
