The window has four bands and no sidebar: a row of things you press, a caption of things that describe the take, the roll, and the chain with a column under it for each effect that is switched on. The split is deliberate. The header is only verbs, the caption under it is only nouns, and once you have noticed that, you can find any control in the window by asking whether it acts on the take or describes it.
What you'll learn
- The four bands of the window and what belongs in each
- Every control in the header, and why the fill moves between them
- The take bar, and which parts of it only appear when they can do something
- The five things the piano roll draws that a normal piano roll does not
- The chain row, and what a slot's number and headline mean
- Every keyboard shortcut, and when the plugin hands a key back to your DAW

3.1 The four bands
From the top:
- The header. Things you press, grouped by what they act on: start a take, hear a take, send it to Song Cage. Plus the licence pill on the right.
- The take bar. Things that describe the take: which take, tempo and anchor, key and octave, what is going out to the track. Plus the tools for correcting a note, which appear only while a note is selected.
- The roll. The take drawn as notes, with the chords above it and a pitch axis that knows the key.
- The chain. Thirteen slots in a row that wraps, with an open strip below for each one that is on.
The window has a 720px minimum, and everything fits at that width with nothing hidden and nothing shrunk. Under 860px the brand keeps its mark and drops the words, because your DAW is already printing "Melody Rack" an inch above them.
3.2 The header
Sing
The one filled button in the window. Press it and you get counted in, then the microphone opens.
The fill moves to whatever will stop the current noise. At rest Sing wears it. While recording, Sing becomes a red Stop. While the local preview is playing, Stop wears it and Sing drops to an outline of itself, still one click away but no longer the thing your hand goes to. This exists because reaching for the big coloured button to stop playback and recording over the take instead is a real thing that happened.
While counting in, the button shows the count and pressing it cancels.
Two small controls sit beside it and describe what Sing is about to do:
- The count-in, cycling through
1 bar in,2 bars inandno count. - click, a metronome through the count-in and the take.
Both go inert while your DAW is rolling, and say why: the take is then timed to the host's bars and the host has a metronome of its own, so a second click out of a second device is worse than none.
Keys and Import
Keys records from a MIDI keyboard or from a clip already on the track, with the same count-in and the same grid. It is not gated on the microphone: a DAW that will not give the plugin a mic still routes MIDI.
Import opens a panel with three ways to bring in a recording you already have: a file, your phone by QR code, or your Song Cage inbox. Dropping an audio file anywhere on the window does the same thing. See Chapter 4.
The reference note
Once there is a take on the roll, a small tuning control appears beside the count-in: press it and you hear a note to pitch against before you sing. It is made inside the plugin rather than by the instrument on the track, so it is always exactly in tune. Before the first take, the same thing is available as a keyboard drawn on the empty stage, which is the moment somebody is actually sitting in silence about to sing.
Play and loop
The plugin's own transport, drawn as a triangle and a square. It exists because hearing a dial move used to mean rewinding your DAW to bar 1 and rolling it, and a plugin cannot move the host's playhead in any desktop format. Same MIDI, same instrument on the track, the plugin's clock.
loop repeats the take while it plays here. Clicking the roll's ruler parks a cursor and playback starts from there instead of the top.
Both are disabled while your DAW is playing, because then the host owns the transport.
Send to Song Cage
One press files the whole take in your Song Cage inbox as an idea: the melody through the rack, every part the rack made as its own take, the progression as the idea's chords, and the key, tempo and metre. See Chapter 10.
The licence pill
On the far right: trial · 9 days left during the trial, and pressing it opens checkout. It disappears once the plugin is licensed.
3.3 The take bar
Five groups, and the spacing says which is which: the gap between groups is three times the gap inside one.
- Which take. Numbers 1 to 5 for the takes the plugin is keeping, with the current one lit. Each carries its own delete, plus copy and flatten. See Chapter 5.
- When. Tempo (typed, when the plugin has no host to read one from) and the anchor, the bar of the song the take starts on.
- Where in pitch. The key row, and the octave buttons that move the whole output up or down after the rack has run.
- What goes out. Two counts,
N sungandN made, in the two lane hues. Terracotta is what you sang, teal is what the rack made, and this is the only place in the window that says so in words. Each count is also the mute for its channel: lit while it goes to the track, dim while it does not. - What you can do with it. The drag handle, Undo, and, while a note is selected, the fix tools.
The fix tools take the drag handle's slot the moment you click a note and give it back when you press Escape, so the bar stays one line at any width.
3.4 The roll
The roll draws five things an ordinary piano roll does not, and each of them answers a question this window kept provoking.
The sung pitch curve
A line through the note blocks showing the actual pitch you sang, frame by frame. Everything downstream reads it; Expression writes it out as per-note bend.
The chords
A row above the notes showing the progression the rack worked out from your melody, so you can see which harmony a correction was made against. Every bar in that row is a place to write a chord yourself: click a chord, or the dim + on an empty bar, and a field opens. See Chapter 6.
The correction marks
Every note In Key moved is drawn against where you sang it: a dashed rule at the sung pitch, and a riser up to the block. Without this the roll showed a note at a pitch nobody sang, drawn identically to one they did, with the sung line running neatly through the middle of it.
Rest on a note and the roll says which of In Key's three questions decided it, with the number to check it against: In Key · up 1 semitone / into C major · sung 43 cents off, a detector guess, or In Key · kept / outside C major · sung 4 cents off. You meant it.
A bright edge on a held note
A note you are holding by hand (see Chapter 7) carries a bright edge down its front. It is an edge rather than a fill, because two blocks at two pitches is a drawing of a chord.
A pitch axis that knows the key
Every row is named, the tonic strongest, the other six in plain ink and the five outside the key dim. So the gutter is not only a ruler: it is a picture of the frame In Key and Harmony are correcting against, and a note on a dim row is one those slots are about to have an opinion on.
The ruler
The strip at the top of the roll is the transport's. A click parks the play cursor on the nearest beat. Dragging either end of the take changes its length: growing is only a setting and the notes stay where they are, shrinking puts the notes outside the edge out of the take without deleting them, drawn washed back until you drag the edge out again. Dragging the take sideways moves its anchor.
When the bar lines are drawn dashed, the grid is a ruler rather than a promise: the take was imported, or recorded through a fallback audio path that cannot honour a start time, so nothing counted it in. It is telling you the truth rather than sitting quietly on a wrong grid.
3.5 The chain
Thirteen slots in a row that wraps rather than scrolls, so all of them are on screen at every window size. Click a slot to switch it on or off; drag it along the row to change the order. With a slot focused, Alt with an arrow moves it one place.
Only the slots that are on carry a number, so the row states the order of the patch you actually have rather than numbering a menu. Under each live slot is the one setting worth printing: 40% on Feel, 3rd above on Harmony, 2 bars on Chords.
Some slots say what they are waiting for, in the same place:
- needs a key on Chords, In Key and Harmony. A progression is a set of degrees in a key, "a third above" is a number of scale steps, and In Key has nothing to pull a note toward.
- needs Chords on Arp. An arpeggiator arpeggiates a held chord, and the chord track is the held chord.
- needs a second take on Morph, which walks between two of them.
Under the row, each slot that is on opens a strip: its controls as dials, packed into columns, in the effect's own order. A control the effect is not reading right now is hidden rather than shown doing nothing. Chapter 8 is every strip in full.
A fresh plugin has only In Key on, and the rack starts with no key, so In Key is a no-op. The window gives your take back exactly as you sang it until you ask for something.
3.6 Keyboard shortcuts
| Key | What it does |
|---|---|
| Space | Stops whatever the plugin has running. Plays the take when nothing is. |
| R | Sing. Cancels the count-in, or stops a recording, if one is running. |
| K | Keys. Same ladder as R. |
| 1-5 | Put that take on the roll. |
| ↑ ↓ | Nudge the selected notes in pitch by a semitone. This also pins them. |
| ← → | Nudge the selected notes in time. |
| S (held) | Sing or play the pitch you want the selected note to be. It takes it when you let go. |
| H | Keep: hold the selected notes where they are, so In Key leaves them alone. |
| J | Join the selected notes into one. |
| C | Cut the selected note in two. |
| ⌫ | Delete the selected notes from the take. |
| Cmd+A | Select every note. |
| Esc | Put the selection down. |
| Cmd+Z | Undo. Also on the take bar. |
Two things are worth knowing about how these behave inside a DAW.
Space never starts a recording. Sing opens a microphone, and a key you can hit by accident should never do that. The asymmetry is the point: space makes things quieter, or plays back something that already exists. R and K do start one, because they are keys you go and find, and R is what every DAW already uses for record.
The plugin hands keys back to the host whenever it would not act on them: with any modifier held (Cmd-A excepted), while the caret is in a field, and, for Space specifically, while your DAW is rolling. A key claimed and then declined is a key swallowed for nothing, and a plugin window that eats the spacebar and does nothing with it is worse than one with no shortcut at all. An edit key is only claimed when its button is enabled, so with nothing selected, every one of them goes straight through to your DAW.
