How it works

From raw archive to prepared library in three steps

Step 1 ~5 minutes

Point Metamix at your library

Add your archive folder and your Rekordbox XML export. Metamix mirrors both into its local database and reads the Rekordbox beatgrid for every track — the timing authority nothing in Metamix overrides.

Step 2 overnight

Analyze and tag locally

Queue the full library and let it run. Analysis runs on the Neural Engine, tagging on local models — a 20k-track library processes overnight in a resumable queue. Interrupted jobs pick up exactly where they stopped.

Step 3 ~10 minutes

Review, then write back safely

Review proposed cues and tags, adjust anything that isn't right, then approve. Metamix snapshots Rekordbox, shows you the exact diff, applies it, and audits every change. Don't like the result? One click undoes the whole batch.

The safety net

Will it overwrite my Rekordbox edits? No.

Your manual edits are sacred

Tracks where you've made manual Rekordbox edits are detected and blocked from automated writes. No exceptions, no "are you sure" — just never.

Every write is a diff first

Before anything changes, you see precisely what will be written — every cue, every tag, before and after — and approve it.

Everything is undoable

Snapshots before every write, an append-only audit log after. One click rolls an entire batch back.

Crash-safe by construction

Jobs are persisted before they run and recover cleanly after power loss, crashes, or forced quits — mid-track, not mid-library.
