Pitch Shift, Presets and Automation
Turn on Enable in the Shift panel to activate these controls. Turn the panel off to hear pitch correction on its own.
| Control | What it changes |
|---|---|
| Transpose | Moves the corrected voice by up to 12 semitones up or down. |
| Formant | Moves vocal resonances independently of pitch by up to 12 semitones in either direction. At 0 st the shifter aims to retain the source resonances. |
| Shift Mix | Crossfades from the tuned original at 0% to the tuned, shifted voice at 100%. |
For an octave layer, choose Octave Double and adjust Shift Mix in the context of the track. Try −12 st for a lower layer. For a fully transposed voice, use 100% and start with Formant at 0 st. Use the editor's Bypass to compare against the dry vocal.
Factory presets
| Preset | Starting point |
|---|---|
| Natural | General vocal correction with a 24 ms Retune Speed. |
| Hard Tune | 0 ms Retune Speed at full Strength, with Flex and Humanize at zero. |
| Gentle | A slower 54 ms retune, reduced Strength and more room for pitch movement. |
| Octave Double | Pitch Shift enabled with +12 st Transpose and 38% Shift Mix. |
Presets adjust tuning and shift controls. Key, Scale, Vocal Range, A4 and your note edits remain selected when you change presets. The panel's dials can be edited after choosing a preset.
Save and automate in a host
Save the host project to recall the Audio Unit instance, including octave-specific note edits. For a reusable preset, use the host's plug-in preset feature if available. The standalone audition app is useful for testing settings before applying them in a session.
In hosts that expose AU parameters, use the host's automation lanes for controls such as Retune Speed, Strength, Transpose, Shift Mix or Bypass. For a key change, automate Key and Scale where the host supports those parameters and listen across the change. Per-octave keyboard edits are saved in the instance state. Use separate instances or tracks if you need different keyboard overrides in different sections and your host cannot switch complete plug-in states.
