Retro Synth LFO and Vibrato
Retro Synth’s LFO (Low Frequency Oscillator) is a multiwaveform, polyphonic modulation
generator that modulates each voice, or note you play, individually. It can be used as a source for
multiple modulation targets.
Retro Synth also provides a dedicated Vibrato LFO for pitch modulation.
Although they are oscillators, LFOs are not audible—but their effects can certainly be heard. The
sole purpose of an LFO is to modulate other sound generating elements of the synthesizer.

LFO/Vibrato parameters
••
LFO/Vibrato tabs: Click to change LFO or Vibrato parameters.
••
Waveform display: Click the buttons at the top of the display to independently choose an LFO
or Vibrato waveform.
••
The sawtooth waves are suitable for bubbling, rhythmic effects.
••
The triangle wave is suitable for vibrato and other evenly-modulated effects.
••
The rectangular waves switch between two values, which is useful for stepping the oscillator
pitch by a fifth, for example.
••
LFO Sync button: Turn on to independently synchronize the LFO or Vibrato speed with the host
application tempo. Turn off to control the LFO or Vibrato speed manually.
••
Rate slider: Drag to independently set the maximum LFO or Vibrato speed.
••
Source pop-up menu: By default, your MIDI keyboard modulation wheel changes the LFO or
Vibrato speed (Rate slider). You can choose aftertouch or both aftertouch and your keyboard’s
modulation wheel to control the Rate parameter.
