Jim:

I read your message regarding piano roll to MIDI conversion.  You might be
interested to know that I have built the roll reader and translator programs
you proposed, pretty much along the lines you suggested.  The entire process
does a very fine job of translating piano rolls to MIDI.

If there are any rolls that interest you in particular,  I would be happy to
scan them for you and translate them to MIDI.  The resulting files are small,
and are easily transferred from one place to another by attaching them as
files to e-mail.

With best regards, I am

Wayne Stahnke
