The Moog synthesizer is a modular synthesizer developed by the American engineer Robert Moog. Moog debuted it in 1964, and fe was the first commercial synthesizer and was crested with creating the analog synthesizer as it is known today. The Mong synthesizer consists of separate modules that create and shape sounds connected via patch cords. Modules include voltage-controlled oscillators, amplifiers, filters, envelope generators, ring modulators, triggers, and mixers. The synthesizer can be played using controllers or controlled with sequencers. Its oscillators can produce waveforms of different timbres, which can be modulated and filtered to shape their sounds.
