Retro Synth Sync oscillator controls
The synthesizer oscillators are used to generate one or more waveforms. You set the basic tonal
color with the chosen waveform or waveforms, adjust the pitch of the basic sound, and set the
level relationships between oscillators. The signal of one or both oscillators is then sent to other
parts of the synthesizer engine for shaping, processing, or manipulation. See Retro Synth lter
controls, Retro Synth amp and eect controls, Use Retro Synth modulation, and Retro Synth
global and controller settings.
Oscillator sync sounds are typically more aggressive than sounds generated with other synthesis
methods, making this engine most suitable for lead and hard bass instruments. The second
oscillator is resynchronized with the rst oscillator each time a note is triggered or each time the
waveform cycle of the rst oscillator restarts.
Sync oscillator parameters
•
Shape 1 and Shape 2 knobs: Rotate to choose the type of waveform that each oscillator
generates. The waveform is responsible for the basic tonal color. The oscillators output a
number of standard waveforms—noise, rectangular, sawtooth, and triangular.
•
Sync Modulation knob: Rotate to choose a sync modulation source, and to set the modulation
intensity. The centered (o) position disables all waveform modulation with the LFO or
lter envelope.
•
Vibrato knob: Rotate to set the amount of vibrato (pitch modulation).
•
Sync knob: Rotate to set the maximum amount of sync modulation. This makes the sound
more or less aggressive. Technically, this control changes the waveform start point of
both oscillators.
•
Mix slider: Move to crossfade (set the level relationships) between the oscillators (Shape 1 and 2).
