Pitch Correction and Note Targets
Start with the song's Key and Scale. Chromatic makes all twelve pitch classes available, while Major, Minor and the other scale choices supply a smaller set of targets. Set A4 to match the reference tuning of the other instruments. The A4 menu offers common values, including 440 and 432 Hz. Hosts that expose the AU's Reference Pitch parameter can set it across 415–466 Hz.
Vocal Range sets the detector's working range. Try Auto first, then Low, Mid or High if the display keeps jumping octaves. If tracking drops out on the singer's lowest or highest notes, try a range that covers more of the take.
Shape how the voice moves
| Control | What it changes |
|---|---|
| Retune Speed | Sets how quickly the voice approaches the target, from 0 to 160 ms. Lower values reach the target faster. |
| Strength | Sets how far the voice moves toward the target. Lower it to leave more of the original pitch deviation. |
| Flex | Lets small deviations around the target pass with less correction. Raise it for more room around the center of a note. |
| Humanize | Slows correction on held notes. Raise it when sustained notes lose too much movement. |
For a light pass, start with Gentle or turn up Retune Speed from Natural. For a stepped effect, start with Hard Tune and set the scale before listening to slides and note transitions. Drag a dial to change its value, double-click or double-tap to reset it, or select the numeric readout to enter a value.
Edit individual notes
The tuning keyboard covers C1 through B6. Use its octave menu to jump to a register or scroll horizontally when the keys extend beyond the editor.
- Targets adds or removes a destination for correction. Remove C4 to send nearby notes to another eligible target while leaving C3 and C5 available.
- Ignore passes input that lands on that note through without correction at the plug-in's dry delay. An ignored note is also excluded as a target. Ignore E♭2 to keep that specific sung note while E♭3 can still tune.
- Link Octaves applies subsequent edits to the same pitch class across octaves. Leave it off to edit a single register.
- Reset Note Edits clears the keyboard edits and brings back the current scale's targets.
The amber highlight shows the correction target, the outline shows the detected input note, and blue identifies ignored keys. The pitch display also shows input frequency, correction in cents and a short correction trace. The target shown is the one used before any transpose. In silence or unpitched passages, Waiting for pitch is expected.
