Hello everyone, In case anyone is curious about my 88-note piano roll
graph paper, I've attached a picture of it. It shows the beginning of
"Dance of the Rose Maidens" by Khachaturian.

The note squares are 1/8-inch long so that there is enough space for
the tracker bar to close for repetition. There are markings for bass
and treble Themodist holes, and a row for sustainer pedal holes.

A free copy of "Dance of the Rose Maidens" in MIDI format is available
to anyone who asks.
