In passing, Rex Lawson's Apple IIE program does just this.  As the
celebrity rocks at the keyboard, all the smudges come floating down on
screen !

Alas, he has written it for his own private Apple operating system which
updates the screen twice as fast, so you can't run it on a Windows Apple
II simulator.  It also displays a digest of the MIDI velocities at the
side, to assist with Duo-Art coding.  Rex is very cautious indeed about
ever doing a real-time auto transfer, because of the lack of any MIDI
standard for piano tone brightness.  As it is you have to tweak the power
even when you're playing back on an electronic instrument.

This might be the Achilles Heel of automatic conversion, in fact.  Steve
Cox of Laguna Rolls has done some sample rolls with literal power
transfers MIDI/Duo-Art.  Like all his rolls, they're beautifully
finished, but they sound like a very facile beginner.  (Since the timing
is accurate, they're entirely acceptable pedal rolls.)  But he uses
SeqWin plus a patented system he had specially written for him, not Rex's
program.  SeqWin does a "Piano Roll Mode" but like most of those sequencer
programs, the display is sideways.
