Minimoog Voyager Rack Mount Edition
The Minimoog Voyager Rack Mount Edition Synthesizer is a monophonic (one note at a time) analog
performance synthesizer housed in a 5U Rack Mount Enclosure. The signal path starts with a bank of
three wide-range, high-stability voltage controlled oscillators, one noise source, and one audio
preamplifier for externally-applied audio signals. The sound modifiers are a dual mode filter module,
containing a dual Moog lowpass mode and a highpass/lowpass mode and one stereo VCA (Voltage
Controlled Amplifier). Modulation sources are two ADSR (Attack Decay Sustain Release) envelope
generators and one multiwaveform LFO (Low Frequency Oscillator).
The digital functions of the Voyager allow for storage of presets, transmitting and reception of MIDI,
and software upgrades via MIDI. The User Interface is a LCD display with variable contrast, +1/-1 and
cursor buttons for navigation, an Enter button for executing functions, and 3 Mode functions for
determining the operation mode of the Voyager. Master Mode allows access to Global Settings and
Utilities; Edit Mode allows access to Items stored as a Preset, and performs the Save function; Panel
Mode allows access to the presets and is the mode used for performance, as well as performance
related features.
Oscillators Module
Three wide-range, high stability VCOs (Voltage Controlled Oscillators) with continuously variable
waveforms.
•
Two FREQUENCY controls vary the frequencies of Oscillators #2 and #3 over a +/-7 semitone range with
respect to Oscillator #1.
•
Three OCTAVE selectors set the frequency ranges of the oscillators in six octave steps.
•
Three WAVE controls provide continuous control over the waveforms of the oscillators, from triangular,
to sawtooth, to square, to narrow rectangular.
•
1-2 SYNC switch synchronizes the Oscillator #2 waveform to the frequency of Oscillator #1, for dramatic
timbral effects.
•
3-1 FM switch provides linear frequency modulation of Oscillator #1 by Oscillator #3.
•
3 KEYBOARD CONTROL switch disconnects Oscillator #3 from control by the keyboard CV, enabling it to
function as a drone or a modulation source independent of the keyboard.
•
3 FREQ switch lowers the frequency of Oscillator #3 into the sub-audio range, enabling it to function as a
low frequency audio or modulating oscillator.
Mixer Module
Five-input mixer for combining the audio sources prior to filtering.
•
Five Input Level controls adjust the relative levels of the oscillator, noise, and external audio input signals.
•
Five Input switches enable the player to quickly switch individual audio signals in and out.
•
External Level LED enables the player to set the correct external audio signal level.
