The history of the development of Coinola machines and the O-Roll format can be found at https://www.rickcrandall.net/a-nickel-for-music-in-the-early-1900s-evolution-of-the-american-orchestrion/ . The O-roll was introduced in 1913. It features perforations for extra instruments plus a 24-note solo section for up to two added instruments such as orchestra bells, xylophone, violin pipes and/or flute pipes. The O-scale plays 78 piano notes including notes at both ends of the range not found in the other American formats that are important to jazz themes. Also the O-roll solo instruments (pipes, xylophone or bells) are connected to the highest 24 playing notes which leaves a good piano compass – almost 2 octaves above middle C – so that the piano plays accompaniment while the solo instrument(s) are turned on and the piano in the solo range is turned off.
The musical selection offered below was recorded on the largest Coinola ever made, the Coinola SO in the Rick Crandall collection. Its instrumentation consists of piano, mandolin effect, xylophone, open wooden flute pipes, metal violin pipes, bass drum, tympani, snare drum, cymbal, triangle, tambourine, Indian woodblock and a 15-inch Chinese crash cymbal.
The pump has a special “amplifier” pneumatic that raises the vacuum level and loudness of the percussion, especially effective with the crash cymbal. Two notes are appropriate about the setup of this particular machine. The wood block is set to operate with a single-stroke beater rather than a repeater. Also when the arrangement calls for pipes as the solo instrument, only the flutes play, whereas when xylophone and pipes are called for, the violins play with the flutes and xylophone so that the pipes can match the sound level of the percussive instrument.
