Logic Pro Retro Synth Table oscillator
The synthesizer oscillators are used to generate one or more waveforms. You set the basic
tonal color with the chosen waveform or waveforms, adjust the pitch of the basic sound,
and set the level relationships between oscillators. The signal of one or both oscillators is
then sent to other parts of the synthesizer engine for shaping, processing, or manipulation.
See filter controls, amp and effect controls, modulation, and global and controller settings.
Wavetable synthesis is useful for creating evolving textures and more clinical sounds. It is
well-suited for pad creation, basses, and sound effects. Despite the clean tone, wavetable
synthesis can also sound warm when combined with the right filter type.
Retro Synth also allows you to create your own custom wavetables.
Table oscillator parameters
Shape 1 and Shape 2 knobs: Rotate to choose from 100 waveforms, known as
Digiwaves. Digiwaves are very short samples of the attack transients of various sounds
and instruments. You can also choose the waves in custom wavetables.
Waveset pop-up menu: Choose a waveset, reverse the loaded wavetable, or create,
save, and delete custom wavetables. See Use the Logic Pro Retro Synth Waveset menu.
Shape/Formant button: Switch between shape and formant modes.
Shape mode: Choose waveforms from default or custom wavesets with the Shape
knobs.
Formant mode: Use the Shape Modulation knob to stretch or compress the formant
spectrum—a series of fixed frequency peaks—in the active waveform (chosen with
the Shape knobs). This is similar to grain compression in a granular synth.
Shape Modulation knob: In shape mode, choose a modulation source and set the
modulation intensity. In formant mode, stretch or compress the formant spectrum of the
active wave. The centered (off) position disables all waveform shape modulation with
the LFO or filter envelope.
This parameter is also available as the Wave Variation (Formant) real-time modulation
target. See Logic Pro Retro Synth global settings.
Vibrato knob: Rotate to set the amount of vibrato (pitch modulation).
