Retro Synth modulation controls
Use Retro Synth modulation
Retro Synths Glide/Autobend, LFOs, and envelopes are known as modulation generators. These
modulation sources are used to control modulation targets, such as oscillator pitch or lter cuto.
The Volume Envelope is dedicated to control of your sound’s level over time. The Filter Envelope
controls the lter over time. See Retro Synth envelopes.
Retro Synths LFO is used as a source for multiple modulation targets. The Vibrato modulation
source is dedicated to control of oscillator pitch. See Retro Synth LFO and Vibrato.
Glide—also known as portamento—and Autobend are hardwired to control oscillator pitch. See
Retro Synth Glide and Autobend.
You should make use of all modulation options because they can help you to create
expressive performances.
If youre new to synthesizers and the concepts behind modulation generators, such as LFOs and
envelopes, see Synthesizer basics overview.

Modulate the oscillator waveform
The Analog, Sync, and Wavetable oscillator waveform shapes can be modulated by following
these steps. In the FM synth engine, you can modulate the FM or Harmonic amount (or both).
1 Move the control toward LFO or Filter Env. Positions further away from the centered (o) position
make waveform modulation more intense.
2 Adjust the controls of the LFO (click the LFO tab if the Vibrato is visible) and Filter Env sections.
See Retro Synth LFO and Vibrato and Retro Synth envelopes.
3 If you are using the LFO, select a waveform.
4 If the (LFO) Sync switch is turned o:
Adjust the Via Amount slider to the right of the waveform graphic to set the maximum
modulation intensity (the highest LFO speed).
Move your MIDI keyboard’s modulation wheel to change the LFO speed. If you don’t want
to use your keyboard’s modulation wheel, click the Via pop-up menu to assign a dierent
MIDI controller.
5 If you are using the Filter Envelope, drag the handles to set the attack, decay, sustain, and release
values. Drag the Velocity slider to set the maximum amount of envelope modulation by velocity.
