If you’re 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. In Logic Pro, move the control toward LFO or Filter Env. Positions further away from the
centered (off) position make waveform modulation more intense.
2. Adjust the controls of the LFO (click the LFO tab if the Vibrato pane is visible) and Filter
Env sections. See LFO and Vibrato and envelopes.
3. If you are using the LFO, select a waveform.
4. If the (LFO) Sync switch is turned off:
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 modulation wheel to change the LFO speed. If you don’t
want to use your keyboard modulation wheel, click the Via pop-up menu to assign a
different 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 sensitivity of envelope modulation
by velocity.
Use vibrato to modulate oscillator pitch
1. In Logic Pro, rotate the Vibrato knob to set the amount of vibrato (pitch modulation).
2. Click the Vibrato tab if the LFO pane is visible.
3. Select a vibrato waveform.
4. If the Sync switch is turned off, drag the Rate note to set the vibrato speed. If the Sync
switch is turned on, vibrato speed is controlled by the Logic Pro tempo. See LFO and
Vibrato.
5. If the (Vibrato) Sync switch is turned off:
Adjust the Via Amount slider to the right of the waveform graphic to set the
maximum modulation intensity (the highest vibrato speed).
Move your MIDI keyboard modulation wheel to change the vibrato speed. If you don’t
want to use your keyboard modulation wheel, click the Via pop-up menu to assign a
different MIDI controller.
