relative to Osc. 1. This allows more than one frequency to be played when a key is
pressed, or to get a very swirly sound when the oscillators are slightly out of tune.
Oscillator 1 does not have a frequency control because it is designed to serve as a
reference oscillator for the other 2 oscillators.
FINE TUNE
:
Fine tune control can be used to tune the Voyager’s oscil or – 2 semitones
for matching an external reference pitch.
WAVE
: Oscillator waveform control
The VCOs of the Voyager feature a continuously variable waveform control. The
legend on the front panel shows the pure waveforms that are available. They are
triangle, sawtooth, square, and rectangular. The waveform is morphed gradually
from one to another as the waveform control is rotated. Because the waveform is
voltage controlled, this can be modulated. This allows generation of some very
interesting timbral changes. By limiting the modulation between the square and
skinny pulse waveform, you can get pulse width modulation. Although the
waveforms can be set from the front panel individually for each oscillator,
modulation is applied to all three waveform controls simultaneously. When using
modulation, it is possible to make the width of the rectangular wave so skinny that it
becomes silent.
3 KB CONT
: Oscillator 3 Keyboard Control On/Off
The 3 KB Control switch, located below the oscillators disables keyboard control of
oscillator 3’s pitch when in the off position. By disabling the keyboard control of Osc.
3, you can use it as a drone, or as a modulation source whose frequency doesn’t
change with the key played.
In addition to turning off the keyboard control of
Oscillator 3, switching this to OFF increases the amount the Oscillator 3
FREQUENCY control changes Oscillator 3’s frequency.
3 FREQ
: Oscillator 3 Frequency range switch Lo/Hi
This selects Oscillator 3’s frequency range. When in the Lo position, Osc. 3 operates
as a subaudio sound source (clicks) or as a modulation source (LFO). When in the Hi
position, Osc. 3 operates with the same available frequency range as Osc. 2.

2 SYNC
: Oscillator 2 Synced to Oscillator 1
Oscillator Sync is an effect caused by resetting an oscillator waveform’s start point
with another oscillator (figure 18). The effect is noticeable if The Synced Oscillator is
a higher frequency than the Reset Oscillator. The main frequency heard is that of
the reset oscillator. As the frequency of the synced oscillator is swept, it reinforces
the harmonics of the reset oscillator. Depending on how applied, the effect can be
aggressive or warm and vocal. This effect is much more dramatic when Oscillator 2
is set to a higher octave than Oscillator 1.
