Effect parameters
On/off button: Turn the effect section on or off.
Effect Type pop-up menu: Choose either the Chorus or Flanger effect.
The Chorus effect is based on a delay line, the output of which is mixed with the
original, dry signal. The short delay time is modulated periodically, resulting in pitch
deviations. The modulated deviations, in conjunction with the original signal pitch,
produce the chorus effect.
The Flanger effect works in a similar fashion to the chorus, but with even shorter
delay times. The output signal is fed back into the input of the delay line. This
feedback results in the creation of harmonic resonances that cyclically move through
the frequency spectrum, resulting in a sweeping, metallic sound.
Mix knob: Set the balance between the original and effect signals. High values result in
stronger effect processing.
Rate knob: Set the modulation speed of the effect.
Tip: Use Logic Pro effects if you need more precise control of chorus and flanging or
want to use both effects simultaneously.
Retro Synth modulation controls
Use Logic Pro Retro Synth modulation
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.
The Volume Envelope is dedicated to control of the sound level over time. The Filter
Envelope controls the filter over time. See Logic Pro 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 Logic Pro Retro Synth LFO and
Vibrato.
Glide—also known as portamento—and Autobend are hardwired to control oscillator pitch.
See Logic Pro Retro Synth Glide and Autobend.
You can also use your keyboard modulation wheel, aftertouch, and velocity as realtime
control sources. See Logic Pro Retro Synth global settings.
You should make use of all modulation options because they can help you to create
expressive performances.
