Moog synthesizer

The Moog synthesizer ( MOHG) is a modular synthesizer invented by the American engineer Robert Moog in 1964. Moog's company, R. A. Moog Co., produced numerous models from 1965 to 1981, and again from 2014. It was the first commercial synthesizer and established the analog synthesizer concept.

The Moog synthesizer consists of separate modules which create and shape sounds, which are connected via patch cords. Modules include voltage-controlled oscillators, amplifiers, filters, envelope generators, noise generators, triggers and mixers. The synthesizer can be played using controllers including keyboards, joysticks, pedals and ribbon controllers, or controlled with sequencers. Its oscillators produce waveforms, which can be modulated and filtered to shape their sounds (subtractive synthesis) or used to control other modules (low-frequency oscillation).
