How to: Prep your crate (Track Editor)
Real DJ software lives or dies on prep: you verify your grids and cues before the gig, and then every mix, set and live show builds on ground you trust. The ① Track Editor view (in the nav, right after Timeline) is Mixx Intelligence's prep station — a work queue over your whole analyzed library that shows, per track, what a human has confirmed and what is still the machine's guess.
The one distinction that matters everywhere:
| Color | Means |
|---|---|
| Green | You set it. A human placed this "1" (or these cues) and the engine treats it as ground truth. |
| Amber / gray | Machine guess. Usually right — but unverified. The mostly-wrong ones are YouTube rips with junk intros (channel idents, DJ tags, voiceovers) that rotate the detected grid. |
Amber isn't "broken". It's unchecked — and the whole point of this screen is to burn that list down on your own time.
The screen
- Filter chips — ⚙ Auto (needs prep) / ✋ Manual (done) / All. Auto is your work
queue; Manual is your trophy shelf.
- Progress — "42 / 839 prepped" top right. This is the number that grows as you work.
- Search — title or artist, filters the list live.
- Per-row status pips:
| Pip | Green | Amber | Gray | |---|---|---|---| | ① downbeat | you set the "1" | — | auto grid | | ⇄ cues | Mix In and Mix Out set | only one of the two set | no cues — the engine picks the window |
The loop
- Open ① Track Editor, stay on ⚙ Auto.
- Click a row — the full-screen grid editor opens (the same one used everywhere: waveform,
① Set Downbeat, Mix In, Mix Out, metronome on K, Space to listen).
- Set the "1" on the real downbeat; set Mix In / Mix Out if you want to own the window (see
guide 10 for the by-ear technique). Everything autosaves — there is no save button to forget.
- Hit ✓ Next unprepped ▸ (n left) — the next queued track opens instantly, previous preview
stops. This is the whole flow: listen, set, Next, listen, set, Next.
- When the queue is done you get the count back on the list, greener than you left it.
A track you prep here is prepped everywhere: the next prepare/rebuild of any mix containing it uses your "1" and cues automatically (a changed grid forces a fresh prepare — no stale audio). And if that track is sitting in the mix you have open on the Timeline right now, the clip slides instantly so you can hear the fix, and the ↻ Rebuild badge counts it — same as an inline Apply "1".
The ① badge on the Timeline
Every clip label on the Timeline now carries a small ① badge:
| Badge | Means |
|---|---|
| ① green | this track's grid is yours — the transition into it rests on a confirmed "1" |
| ① amber | machine guess (hover shows the detection confidence) — worth a listen |
Click the badge to open the inline transition editor for that track directly. One glance down the timeline tells you which transitions rest on verified ground and which are trusting the machine — so when a mix sounds off, you already know where to look first.
Two rules
- Green means a human confirmed it — nothing else. A track can carry an auto-detected
downbeat value and still be amber; the flag flips only when you set it. That's deliberate: it keeps "verified" honest.
- Prep beats firefighting. Ten minutes in the Track Editor queue after every import batch
costs less than hunting a rotated grid mid-mix later. The suspect tracks are almost always the rips with tagged intros — they float up naturally as everything clean gets confirmed around them.
