The Minimoog Voyager or Voyager is a monophonic analog synthesizer, designed by Robert Moog and released in 2002 by Moog Music. The Voyager was modeled after the classic Minimoog synthesizer that was popular in the 1970s, and is meant to be a successor to that instrument.
Like the original Minimoog, the Voyager has six sound sources. Five of these (three voltage-controlled oscillators with switchable waveforms, a noise generator, and an external line input) pass to a mixer with independent level controls. The mixed output of the sources is then passed through the voltage-controlled filter and a voltage-controlled amplifier, each of which has its own ADSR (Attack-Decay-Sustain-Release) envelope generator. The voltage-controlled filter can itself be made to oscillate, thus comprising the Voyager's sixth sound source.
In addition to features from the original Minimoog, the Voyager was designed to have a memory bank capable of storing 128 presets, a touch pad modulation control, dedicated low-frequency oscillator (LFO), two modulation busses (one controllable via the modulation wheel and the other with a foot pedal), two ADSR envelopes for filter and amplifier control, a pressure-sensitive keyboard, 14 voltage-control inputs, and MIDI input/output.
