Retro Synth modulation in Logic Pro for iPad
Retro Synth Glide/Autobend, LFOs, and envelopes are known as modulation generators. These modulation sources are used to control modulation targets, such as oscillator pitch or filter cutoff.
Glide—also known as portamento—and Autobend are hardwired to control oscillator pitch. See Retro Synth Glide and Autobend.
The Amp Envelope is dedicated to control of the sound level over time. The Filter Envelope controls the filter over time. See Retro Synth envelopes.
The 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.
You can also use your keyboard modulation wheel, aftertouch, and velocity as realtime control sources. See Retro Synth global and controller settings.
You should make use of all modulation options because they can help you to create expressive performances.
If you’re new to synthesizers and the concepts behind modulation generators, such as LFOs and envelopes, see Intro to synthesizers.
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).
In Logic Pro, move the Shape Mod control to a position away from the centered (off) position.
Adjust the controls of the LFO and ADSR - Filter sections. See LFO and Vibrato and envelopes.
If you’re using the LFO, select a waveform.
If the (LFO) Sync switch is turned off:
Adjust the LFO Via Amount knob to set the maximum modulation intensity.
Move your MIDI keyboard modulation wheel to change the LFO depth. If you don’t want to use your keyboard modulation wheel, tap the LFO Via Source pop-up menu to assign a different MIDI controller.
If you’re using the Filter Envelope (ADSR - Filter), drag the handles to set the filter attack, decay, sustain, and release values. Drag the Filt Vel knob to set the sensitivity of envelope modulation by velocity.
Use vibrato to modulate oscillator pitch
In Logic Pro, rotate the Via Amount knob to set the amount of vibrato (pitch modulation).
Select a vibrato waveform.
If the Sync switch is turned off, adjust the Rate knob to set the vibrato speed. If the Sync switch is turned on, vibrato speed is controlled by the project tempo. See Retro Synth LFO and Vibrato.
If the (Vibrato) Sync switch is turned off:
Adjust the Via Amount knob to set the maximum modulation intensity.
Move your MIDI keyboard modulation wheel to change the vibrato depth. If you don’t want to use your keyboard modulation wheel, tap the Via Source pop-up menu to assign a different MIDI controller.
