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¢, amber beyond that, turning 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 1–9, or hold the right mouse button / `Q` and flick)

1 Pitch: Drag up or down by the steps of the key, Shift-drag by semitones, ⌘-drag for cents. Double-click tunes it to the nearest note in the key.
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 a note earlier or later. Drag one of its ends to make it longer or shorter at its pitch: its attack and release keep their speed and the held part stretches, up to 2.5 times. A note that meets it there follows, so a phrase stays whole (Shift: that end alone). Double-click puts the note back.
6 Volume: Drag up or down for ±dB. Double-click takes the note out (its separation is taken out of the mix, so a faint trace of it can remain), and puts it back.
7 Draw: Drag along a row to add a note the detector missed.
8 Formant: Drag up or down to move the note's formants (its timbre) up to ±12 semitones, keeping its pitch: brighter and smaller up, darker and larger down. The teal line through a note shows where its formants now sit. Double-click resets it.
9 Harmonics: Drag up or down to make the note brighter or darker (its harmonics tilted, its level kept). The Harmonics card shows each harmonic as sung, faintly: drag a bar to set that harmonic's level (drag across to draw a shape; double-click a bar to put it back), or choose Warm, Bright or Hollow. Double-click a note resets it.
Fine: Hold ⌘ while dragging with any of these for fine steps: cents, 0.01 st of formant, 0.1 dB, a fifth of the distance in time.

Notes

Select: Drag a box on empty space; Shift or ⌘-click adds one; ⌘A selects all. A drag on one edits them all.
Duplicate: ⌥-drag a note or the selection. ⌘C then ⌘V pastes copies at the playhead; ⌘D doubles the selection an octave up, ⇧⌘D a third up in the key.
Nudge: ↑ ↓ move the selection a step of the key (Shift: a semitone, ⌘: 5 cents, ⌥: 1 cent); ← → 10 ms earlier or later (Shift: 50 ms); ⌥← ⌥→ move the notes' ends by 10 ms, ⌥⇧← ⌥⇧→ their starts.
Fine tuning: In the Note card, Fine is how many cents the note sits from the nearest semitone: drag it, or click any value there and type it (35c, -2, 442 Hz). Snap in the toolbar sets what a Pitch drag steps by: the key, semitones, or nothing. Tune to in the Tuning card chooses what in tune means: the voices around each note, or A4 at a frequency you set.
Fix the list: Delete removes a wrong note, J joins the selected ones.
Key: Guessed from the notes (Auto), or set it in the toolbar. Its notes are marked with dots on the keyboard, a larger one on its tonic. Notes are tuned to the key's notes, but one sung within 30¢ of a note outside it (a leading tone, a chromatic passing note) is taken as meant and stays there. Chromatic uses every semitone.
Solo: In the Detect menu, for one voice or instrument: a lead vocal, singers in unison, a bass line, a solo violin or sax. The voice is followed as a single line, and each note is that stretch of the recording itself, so nothing is separated and what lies between phrases (breaths, consonants) is never touched. Notes sets how readily a new note begins: to the right for trills and fast runs, to the left for fewer, longer notes; it applies to the phrases of the selected notes, or to everything with nothing selected. Sound says what the track is, which sets the pitches its notes are looked for between: Auto finds them from the recording, or choose Voice, Bass (a bass guitar's low notes are under any voice) or Instrument (anything, to a flute's top); the notes are found again, and notes found as they were keep their edits. With Consonants on, an s or a t inside a note's stretch stays as recorded when the note is tuned, and keeps its length when the note is stretched. Select all and use Correct pitch… to tune a whole take.
Sibilants: With the Sibilants tool (0), drag a note up or down: its s, t and breath sounds (whatever in it has no pitch) get louder or softer, its sung part left exactly as it is. Down to the bottom takes them out; double-click takes them out or puts them back. Or set Sibilants in the Note card. Best on Solo tracks, where each note is the recording itself; in a choir's separated notes there is little of them to reach. A dotted line under a note shows its sibilants are changed.
Fades: With the Volume tool, drag a note's start or end sideways: it fades in from silence, or out to silence, over that long (the blob tapers to show it). Or set Fade in and Fade out in the Note card. A fade needs no pitch shifting: it is exact.
Transitions: Where one note is sung straight into the next, drag the join sideways with the Drift tool, or set Transition in the Note card: the pitch slides from one note to the other over that long, as a smooth glide, in place of the slide as sung. Longer for a portamento, shorter for a cleaner change. 0 is as sung.
Level: In the inspector: evens out the loudness of the selected notes (or all), by the amount: each note's Volume moves toward the typical loudness of its track (or of every track, with Each track to its own level off), measured on the note as sung. Muted notes stay muted. Each release is one undo step.
Tighten entries: In the inspector: pulls notes heard together (within 120 ms) toward one time, by the amount: Together meets in the middle, Grid quantizes to a tempo. On the selection, or every note.
Correct pitch…: Pulls the selected notes (or all) toward the nearest note in the key, in the tuning of the voices around them, and straightens their drift. It tunes the pitch each note holds, not its average, so a scoop into a note doesn't pull it off; a note that holds one pitch and then another is split where it moves, and each part tuned.

Tracks

Several recordings: Open several files at once, or Add tracks… in the Tracks card: each is a track, and every note of every shown track can be selected and edited together, by every tool and by Correct pitch and Tighten entries. In the plugin, every OmniPitch on the song's tracks shows here, each where its take sits in the song.
Show, mute, solo: In the Tracks card: the eye shows or hides a track's notes (hidden, they are left out of the selection and the macros); M and S mute and solo it for listening. Click a track's name to select its notes (Shift adds them). C colours the notes by track; an amber or red edge still marks a note off pitch.
Follow a track: Tighten entries, Follow: the selected notes (or all shown) move toward the entries of the track chosen, which stays as it is: a ragged ensemble tightened to a lead or a guide track.

Listening and moving around

Play: Space. Click the ruler or waveform to jump. In the plugin, Space starts the song; with it stopped, the play button or a click on the waveform plays the tracks here from that point, edited, through the plugin (Space or the button stops it). E switches original / edited, A turns hearing notes on and off.
Undo, redo: ⌘Z, ⇧⌘Z (or ⌘Y). The History card lists every step: click one to go back, or forward, to it.
Scroll: Pans; ⌥-drag pans too. Pinch or ⌘-scroll zooms in on the pointer, time and pitch together. Scrolling over the ruler zooms time alone; ⌥-scroll (or Shift-scroll), or scrolling over the piano keys, zooms pitch alone.
Piano keys: Click a key to hear its note, in the tuning of the voices around the playhead: a starting note.
Loop: Drag along the ruler to loop that stretch; L turns the loop on or off (with none yet, around the selection).
Zoom: + − zoom time, ⌥+ ⌥− pitch; the sliders under the roll do the same. Z zooms to the selection; hold Z and drag a box to zoom to it. F fits everything, ⇧Z goes back to the view before. Drag the waveform down to zoom in and up to zoom out (sideways pans). In the overview, drag the frame's edges to take in more or less. Zoomed far in, each row shows a dashed line where a note is exactly in tune.
Follow: The button beside Fit: whether the view keeps up with the playhead. Home and End move the playhead. I shows or hides the inspector.
Your own audio: Drop a file on the roll, Open one (⌘O), or Record (R). Set the detector first: Voices for singing, General for instruments.
