The Optigan (a portmanteau of Optical Organ) is an electronic keyboard instrument designed for the consumer market. The name stems from the instrument's reliance on pre-recorded optical soundtracks to reproduce sound. Later versions (built under license and aimed at the professional market) were sold under the name Orchestron.
Engineering work on the project began in 1968 and the first patents issued in 1970. The Optigan was released in 1971 by Optigan Corporation, a subsidiary of toy manufacturer Mattel, Incorporated of El Segundo, California with the manufacturing plant located nearby in Compton, California. At least one TV commercial from the era is extant, featuring the Optigan demonstrated by actor Carl Betz (best known for his role as the father on The Donna Reed Show). The Optigan was promoted in at least one Sears-Roebuck catalog. All rights to the Optigan, the disc format, and all previous discs were sold in 1973 to Miner Industries of New York City, an organ manufacturer who formed a subsidiary, Opsonar, to produce it. Miner had record sales for a time, in part due to Opsonar. However, sales declined shortly thereafter and production of the Optigan and its discs ceased in 1976.
The Optigan's playback system functioned much like the storage and reading of an optical soundtrack as was used in motion pictures, using a light bulb to energize a row of photodiodes on the opposite side of spinning, 12" diameter clear plastic film discs (officially referred to as "Program Discs") encoded with fifty-seven concentric optical tracks. The system then translated the analog waveforms on the disc to an audio signal. A flip-down door beneath the keyboard allowed access to the disc's loading area to the left of the unit and a disc storage area to the right. Program discs were loaded by simply sliding them onto the felt-covered platform; a V-shaped notch on the front of the panel aided in alignment. When power was applied and the front cover closed, a spindle engaged the center hole of the disc and a motor-driven idler wheel spun the disc on the spindle. The power switch itself was mechanically linked to the disc's drive system; lowering the front panel dropped the spindle and disconnected power to the instrument, allowing the program discs to be changed without the need to fully power down. A broad, flat, white plastic cleaning tool with a purple, simulated velvet cleaning surface was supplied with each Optigan to allow periodic cleaning of the photoelectric cell, located near the rear of the instrument.
