VCO: Voltage Controlled Oscillators
There are two voltage controlled analog oscillators for
each voice on prologue. Oscillator Parameters include
theseingsfortheoscillatorpitch(OCTAVE,PITCH)
andthewaveform(WAVE,SHAPE).
WAVE switch [ , , ]
This sets the waveforms for Oscillators 1 and 2.
Square wave: This waveform has a sound that can be used to create wind instru-
ment-type timbres, electronic sounds, and imitate vintage video games.
Triangle wave: This waveform has less high end harmonic content than a sawtooth
or square wave, and so has a more round, less aggressive feel.
Sawtooth wave: This waveform is the most common analog synthesizer waveform,
and can be used to recreate anything from standard synth sounds to basses, brass,
and strings.
OCTAVE switch [2’, 4’, 8’, 16’]
The pitch of Oscillators 1 and 2 can be set in octave steps.
PITCH knob [-1200...+1200]
The pitch, or tuning, of Oscillators 1 and 2 can be set using steps of one cent.
