How to use OmniPitch

Each blob is one note, at the pitch it is sung. The line through it is its pitch curve, its thickness its loudness; its colour shows its tuning against the voices around it: blue within 10¢, turning amber by 25¢ and red by a quarter tone (50¢) sharp or flat. Correct pitch… and double-click pull notes toward that same tuning, so a choir that has drifted stays together. Click a note to hear it on its own.

Tools (keys 1–7, or hold the right mouse button / `Q` and flick)

1 Pitch: Drag up or down by semitones, ⌘-drag for cents. Double-click snaps to the nearest semitone.
2 Modulation: Drag to scale the vibrato, 0–200%. Double-click flattens it.
3 Drift: The same for slow pitch wander (scoops, sags), keeping the vibrato.
4 Split: Click where a note should become two.
5 Time: Drag earlier or later. Double-click puts it back.
6 Volume: Drag up or down for ±dB. Double-click mutes.
7 Draw: Drag along a row to add a note the detector missed.

Duplicate: ⌥-drag a note or the selection.
Fix the list: Delete removes a wrong note, J joins the selected ones.
Correct pitch…: Pulls the selected notes (or all) toward the nearest semitone, in the tuning of the voices around them, and straightens their drift.
