Optigan

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 looked like a scaled-down version of the electronic organs of the day. The various cabinet designs and their matching benches were simulated wood made out of a molded plastic the manufacturer dubbed "Temperite" and finished with matching speaker grille cloth and occasionally reverb units inside the unit. A mechanical reverb unit and cabinetry with genuine wood veneer were available as extra-cost options; the control for the reverb on units so equipped is located below the power switch. Non-reverb equipped Optigans feature a metal plate which reads "Stereophonic" in raised relief and which hides the unused opening. Reverb-equipped units had a slightly different plate which read "REVERB Stereophonic" affixed immediately to the left of the rocker switches and above the power switch. According to optigan.com, two piano bar prototypes were produced. The Optigan played in stereo through two solid state amplifiers with the right-hand keyboard assigned to the instrument's right channel and the chords and effects assigned to the left.
