This is my piano roll graph paper. It's configured for 88-note
players. It's 11-1/4 inches wide. It has indications for treble
and bass Themodist (snake bite) holes, and sustainer pedal as well.
The note holes are nine-to-the-inch (across) and 1/8-inch apart
(lengthwise) for sure repetition with trills.
It's perhaps slightly heavier than the piano roll paper used nowadays
by QRS and others, and it cuts very nicely with a sharp blade. The
printing is very precise.
Price is $4.50 for 30 feet of paper, or $12.00 for 100 feet, without
spool, plus a modest shipping and handling charge. For more
