The MINIMOOG' VOYAGER OLD SCHOOL has a hinged, multi-position panel and a solid hardwood cabinet. The power supply accepts any power voltage from 100 volts to 240 volts.
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 two Moog filters 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).Control devices include a 44-key keyboard with velocity and afterpressure outputs, pitch bend and modulation wheels, and many control/pedal input jacks.
Three wide-range, high stability VCO's (Voltage Controlled Oscillators) with continuously-variable waveforms.
* FREQUENCY controls (2) vary the frequencies of Oscillators #2 and #3 over a +/-7 semitone range with respect to Oscillator #1.
* OCTAVE selectors (3) set the frequency ranges of the oscillators in six octave steps.
* WAVE controls (3) 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 KB CONT switch disconnects Oscillator #3 from control by the keyboard, thereby enabling it to function as a drone.
* 3 FREQ switch lowers the frequency of Oscillator #3 into the sub-audio range, thereby enabling it to function as a low frequency audio or modulating oscillator.
Five-input mixer for combining the audio sources prior to filtering.
* Input Level controls (5) adjust the relative levels of the oscillator, noise, and external audio input signals.
* Input switches (5) 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.
Dual mode filter module includes dual lowpass and highpass-lowpass filtering. Dual lowpass mode consists of two Moog lowpass-resonant filters in parallel, one per output channel. Highpass-lowpass mode consists of Moog lowpass filter in series with a highpass filter.
* CUTOFF control sweeps the frequencies of both filters throughout the audio range.
* SPACING control sets the spacing between the frequencies of the two filters, over a +/-3 octave range.
* RESONANCE control adjusts the resonance of both filters, from none (pure lowpass response) to filter oscillation.
* KB CONT AMOUNT control sets how much the filters open and close as the player presses different keys on the keyboard.
* Dual Lowpass/Highpass-Lowpass switch selects between dual lowpass operation or highpass-lowpass operation.
The Envelopes Module generates two wide-range ADSR (Attack Decay Sustain Release) envelopes. The Filter Envelope sweeps the filter and is available for modulation shaping. The Volume Envelope shapes the overall volume.
* ATTACK controls (2) determine the attack times of the envelopes.
* DECAY controls (2) determine the decay time constants of the envelopes.
* SUSTAIN controls (2) determine the sustain levels of the envelopes.
* RELEASE controls (2) determine the release time constants of the envelopes.
* AMOUNT TO FILTER control determines how much the filter envelope will open and close the filter, from full negative (inverted envelope) to full positive (non-inverted envelope).
* ENVELOPE GATE SWITCH selects whether the envelopes will be triggered by the keyboard, on , or by an externally-applied gate.
Low Frequency Oscillator generates triangular, square, Sample & Hold, and smoothed Sample & Hold waveforms for use as modulating signals.
* RATE control sets the LFO rate over the range 0.2 Hz (one cycle every five seconds) to 50 Hz (fifty times a second).
* WAVE selector selects the Triangle, Square, S+H Stepped, or S+H smoothed LFO Waveform for use in the Mod Busses.
* RATE LED provides visual indication of the LFO rate.
Modulation Busses Module
Selects the sources, destinations, and shaping signals for the Mod Busses.
* SOURCE selectors (2) selects the modulation source from the LFO, Oscillator# 1, Osc. #2, Oscillator #3, Noise, or the MOD2 input (normalled to +5V (ON)).
* DESTINATION selectors (2) selects the modulation destination from all the audio oscillators, just Oscillator #2, just Oscillator #3, the filter cutoff frequencies, the oscillator waveforms, or LFO Rate.
* CONTROLLER selectors (2) selects the Mod Wheel, The MOD1 input (normalled to +5V (ON)), Velocity, Afterpressure, the Filter EG, or the Volume EG to control the output level of the modulation signal on that bus.
* AMOUNT controls (2) sets the maximum overall modulation amount for each bus.
* MASTER VOLUME control sets the overall level of the instrument's audio outputs.
* HEADPHONE VOLUME control sets the overall level of the headphone output.
* HEADPHONES jack: 1/4' tip-ring-sleeve phone jack for regular headphones.
Glide and Fine Tune Module
* GLIDE varies the speed at which the keyboard voltage changes, from instantaneous to several seconds.
* FINE TUNE adjusts the overall tuning of the instrument.
Player Control Interfaces
* 44 KEY KEYBOARD produces Pitch, Gate, Velocity, and Pressure control outputs.
* WHEELS: Pitch Wheel bends pitch over a range of up to +/-1 octave. Mod wheel controls the gain of the MOD WHEEL bus.
* GLIDE and RELEASE switches provide real-time on-off control over the glide and release functions.
Rear Jack Panel
These ten jacks have red nuts. They accept either expression pedals or control voltages, and control the following performance parameters:
* FILTER CUTOFF
* MOD2 - EXTERNAL MODULATION SOURCE
* MOD1 - EXTERNAL CONTROL OF THE PEDAL MOD. BUS
* SAMPLE AND HOLD IN
* ENVELOPES RATE
* LFO RATE
A footswitch or gateapplied to this input will reset the LFO waveform to the beginning of its cycle.
A footswitch or gate applied to this input will start the envelopes.
Sample and Hold Gate
A gate signal applied to this jack will trigger a new sample and hold voltage.
foot switch plugged into this jack will have the same effect as depressing the corresponding switch on the left hand controller panel.
KB CV/Gate Outputs
These jacks Output a 1V/Octave CV and a +5V gate control signals from the 44-note keyboard.
Mixer Ext In
Plug any instrument-level or line-level audio signal in this jack to combine with the oscillator and noise signals prior to filtering.
Mix Out/Filter Audio In
The output of the audio mixer appears here, before being fed to the filter. Normally, the Mixer output is bridged directly to the filter input. If you plug something into this jack, that breaks the normal connection. Using a standard insert cable (1/4" TRS plug to two 1/4" TS plugs) this jack can be used as an effects loop for external processing of the Mix before it goes to the filter.
Left(Mono) and Right Audio Outputs
The audio outputs are 1/4 " unbalanced outputs. The two output channels are summed to mono when only the left(mono) output is used.
The Accessory port delivers
the Control Voltage and gate
signals generated inside the Voyager to a standard DB-25
connector. This is designed for use with the VX-351 Voyager CV Expander.
The TNC Lamp Socket provides 12VDC for a gooseneck lamp.
The Voyager's power input accepts a standard IEC grounded power cable. The Voyager works from 100-250 VAC, 50-60 Hz. The Power consumption is 20 Watts, max.
