List of QRS Apollo 15.25" Rolls, compiled by Troy Taylor

"Apollo Concert Grand" apparently was the name of the first mechanism designed to play music rolls
15.25 inches wide, perforated at 6 holes per inch, for 88 playing notes.

The label on the leader has no
catalog number and no mention of QRS.

Unknown roll series,
not for the Solo Apollo player system...

The "Solo Apollo" expression mechanism featured two separate pneumatic actions, one to play the Accompaniment
and the other to play the melody or Solo part of the song. The music roll also was 15.25 inches wide but it was
punched at 9 holes per inch, for 134 channels total to control the notes plus expression controls.
