The original Moog Taurus was a foot pedal-controlled analog synth with 13 foot keys and a five octave range, though it was primarily used for bass work. The Taurus was originally intended as a bass complement to the Apollo and Lyra keyboard synths in an ensemble set-up referred to as the Constellation. 

Two later versions of the Taurus were released, the unpopular and short-lived Taurus II (basically a foot-controlled Moog Rogue) which ended production after a two year run in 1983, and the Taurus III reincarnation of the original. Only 1000 specimens of the Taurus III were made in 2010, each one a fully analog faithful reproduction of the Taurus I. 

Years of Production: ca. 1974 -1981
