The Moog Taurus is a foot-operated Moog Rogue. In 2010, Moog issued the Moog Taurus III, which, despite the addition of some features, closely emulates the analog circuitry of the Taurus I.

The Taurus is associated with progressive rock, and has been used by bands like Yes and Rush, among others.

The Taurus was originally intended to be part of a larger Moog Music synthesizer ensemble called the Constellation. In addition to the monophonic Taurus, the Constellation would have included two keyboards: the monophonic Lyra and polyphonic Apollo. The intention was that the Apollo and Lyra be played with both hands, while bass notes could be played by foot on the Taurus.[1] The Constellation configuration was used prominently on the 1973 Emerson, Lake & Palmer album Brain Salad Surgery. 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 was redesigned by Moog's Director of Engineering, David Luce, and released as the Moog Polymoog from 1975 to 1980; the Taurus pedal was released as a separate unit from 1981 to 1983. The Lyra synthesizer was never commercially released.[2] William Alexander, a roadie for ELP, described the Lyra as "a Minimoog on steroids".[3]

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, modulation 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.[4] Instead, the control panel was raised so that the player could manipulate it manually during performance.[5]

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.[6] In general, the Taurus II is considered to be inferior to the original model because of its synthesis engine.[5]

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 NAMM Show, shortly after Robert Moog's death.[7] 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.[8]

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 USB and MIDI support, a larger memory capacity, and velocity sensitivity. The Taurus III also adds an arpeggiator and an LFO.[5]

Synthesis model

The Taurus is monophonic, with two oscillators in its single voice. For the Taurus I and Taurus III, only one waveform was available: a distorted sawtooth wave.[5] The Taurus II introduced a second waveform, the pulse wave.[4] All models of the Taurus use a 24db/octave resonant lowpass filter. Although the early models did not include an LFO, the Taurus III has an LFO that can be routed to either oscillator pitch or filter frequency.[5]

Notable users

The Taurus is well known for its use by progressive rock bands, such as Pink Floyd, Led Zeppelin, Rush, Yes, and Genesis.[5][1] Other bands, such as U2 and The Police, have also used the synthesizer.[1] John Hackett was known for playing the foot pedals of a Taurus with one hand, while using the other hand to change the octave range.[5]

According to Moog Music, artists that purchased the Taurus III included Yes, Rush, The Black Keys, Animal Collective, Jean Michel Jarre, Weezer, and Dave Matthews Band.[8]
