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 generates 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 through the Mod Busses 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.
1 à 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 more 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.
