B. The Oscillator Section
The Oscillators are the main sound source of the Voyager. The oscillators in the Voyager are all analog
Voltage Controlled Oscillators, or VCOs. They feature a temperature regulation circuit that provides them
with excellent tuning stability. The VCOs can produce a total musical range of 8 1⁄2 octaves! In addition, the
frequency of oscillator 3 can be set to the sub-audio range (<20Hz) for use as a second LFO.

Oscillator 1 performs as a master oscillator to which Oscillator 2 and 3 are tuned. The timbres of the
oscillators are adjusted by their variable Waveform controls. In addition, there are switches for Oscillator
2 sync to 1; linear frequency modulation of Oscillator 1 by 3; Oscillator 3 keyboard control on/off; and
Oscillator 3 Lo or Hi frequency range. The frequencies of the Oscillators are controlled by a number of
sources. The main source is the pitch CV generated by keyboard or by MIDI Note ONs. A glide circuit can
be switched in between the Keyboard CV and the oscillators to slow the voltage changes between notes,
resulting in a glissando effect. The Keyboard CV then is mixed with the Octave switch CV, the Frequency
control (Oscillators 2 and 3), the Pitch Bend Wheel, the Fine Tune control, and the output of the Mod
Busses when the ‘Pitch’ destination is selected.
Oscillator Section Controls:
Octave:
Each Oscillator has a 6-position
OCTAVE
switch that selects the relative frequency range. To hear how it
works, turn off Oscillators 2 and 3 in the Mixer. Turn Oscillator 1 on and set its level to 5. Play a note on
the keyboard and rotate the Oscillator 1 octave switch clockwise one click – the note will rise an octave.
You can use this control to change the frequency range that the keyboard controls. The panel markings 32’
up to 1’ are octave standards based on organ stops. On the 16’ setting, MIDI Note number 93 is A440
(equivalent to the “A” key above middle C) .
