The Moog Taurus is a foot-operated
analog synthesizer
An analog synthesizer () is a synthesizer that uses Analogue electronics, analog circuits and analog signals to generate sound electronically.

. It was originally conceived as a part of the Constellation series of synthesizers. The initial Taurus I was manufactured from 1975 to 1981; a less popular redesign, Taurus II, followed from 1981 to 1983. Instead of a conventional keyboard, the Taurus uses an organ-style pedal board similar to the

spinet organ. This control method was chosen because the Taurus was intended to be played by foot while the player's hands played one or more keyboards, although it was often used by guitarists. While the original Taurus featured its own synthesis engine, the Taurus II was essentially the same as the
Moog Rogue. In 2010, Moog issued the Moog Taurus III which closely emulates the analog circuitry of the Taurus I, in addition to adding some modern features.

''. The band also used the Constellation on their subsequent tour, albeit without the Taurus pedal. However, the Constellation was never formally released. Instead, the Apollo synthesizer, designed by Moog's Director of Engineering, David Luce, was redesigned and greatly upgraded to the
Moog Polymoog, which was produced from 1975 to 1980; the Taurus I pedal, also designed by Luce, was released as a separate unit from 1975 to 1981. The Lyra synthesizer, designed by Robert Moog, was never commercially released.
William Alexander, an engineer for ELP, described the Lyra as "a

Taurus II
The original Taurus I was succeeded by the Taurus II, which was produced from 1981 to 1983. The Taurus II uses the same synthesis engine as a contemporary lead synthesizer, the
Moog Rogue. The Taurus II was controlled through 18 foot pedals,

and
pitch bend wheels, and a
CV interface. The synthesizer also increased the amount of timbres and effects available. However, the Taurus II had no patch memory or foot controls apart from the pedals.
Instead, the control panel was raised so that the player could manipulate it manually during performance.
A version of the Taurus II pedal board with CV & gate outputs and no synth module was available - the model 343C Taurus II Controller.
The value of the Taurus II did not appreciate as significantly as that of the Taurus I; in 2000, Mark Vail noted that the Taurus II was worth only about half as much as its predecessor.
In general, the Taurus II is considered to be inferior to the original model because of its different synthesis engine.
Taurus III
In 2010, Moog released a redesigned version of the Taurus called the Taurus III in a limited run of 1,000 units. According to Moog's creative head Cyril Lance, a reissue of the Taurus had been in high demand since his first convention with Moog, the 2006

's death.
In 2007, Moog CEO Mike Adams proposed that if customers could generate pre-order sales of 250 units, the Taurus would go into production. Work on designing the Taurus III, led by Lance, began that year after 250 units were pre-ordered. Production ceased in June 2012.
The Taurus III overlooks many of the changes made for the Taurus II, instead more closely emulating the original model. For instance, there is only one waveform available for the unit's two oscillators. Some features are added, such as
