Rekordbox Library AI Companion
Your library, finished. Crate Control fills in everything rekordbox is missing — genre, artist, artwork, BPM, key, moods, vocal components, a 1–10 energy score and auto cue points — and builds playlists of tracks that play well together, using AI that runs entirely on your Mac. You review every proposal. Nothing is written until you press Apply.
Free 14-day trial · $4.99 one-time, no subscription · macOS 13+ · notarized by Apple
Your library at a glance: what's complete, what the AI has covered, and one button that fills in the rest.
Crate Control reads your rekordbox library, matches tracks on Beatport and runs the AI analysis on your Mac — genre, artwork, moods, energy, cue points.
Every result lands on one review list — audition cues, zoom artwork, fix a genre, add or drop tags. Filter by what's pending; edit anything inline.
One click writes it to rekordbox — after backing up your database, restorable in-app. Only empty fields are filled; your edits and cues are never touched.
The Review list — every proposal in one place, one row per track. Nothing touches rekordbox until you press Apply.
Auto-tag genre, energy and key · set cue points on the beat grid · build playlists of similar tracks
A ladder of matching tiers, not one search: files bought from Beatport match by the store's own track id hidden in their tags; text search is length-verified and word-order aware; artist-less titles retry inside a BPM window with your library's key breaking ties. Genre, artist, label, release artwork, BPM and key — the wrong edit never gets tagged.
Open-source Essentia models score genre, moods (Party, Dark, Melancholic, Epic, Deep…), vocal components (Vocal / Instrumental, voice gender, instruments), situation and a DJ-style 1–10 energy — from the audio itself. No cloud, no tokens, no uploads.
Energy analysis snapped to rekordbox's own beat grid proposes hot cues — Intro, Build, Drop, Break, Outro — that land exactly on the downbeat. Audition each one on the built-in waveform player before a single cue is written.
Pick a track, a selection or a whole playlist and the similarity engine ranks your library by mood, themes, instruments, BPM (half/double-time aware), Camelot key, genre and energy — each match with a readable reason. Send the results to an existing rekordbox playlist or a new one.
Fix a title, pick a genre, add or remove tags, change a track's energy — right in the library grid. Every edit is staged, marked and revertable, and a tag-confidence setting (strict / balanced / open) re-tags the whole library instantly from the stored scores, no re-analysis.
Files with missing or wrong metadata are identified Shazam-style: an acoustic fingerprint looked up in the open AcoustID database recovers the real artist and title — even for unreleased mixes no store sells. Artwork falls back through four sources, ending at the cover embedded in the file itself and the iTunes catalogue.
Anything the matcher refuses gets a live candidate picker: Beatport's own waveform next to your file's, a two-minute store preview per candidate, lengths, BPM and key with agreements in green. One click writes the match. Tags land in My Tags, in Comments (Ambient, Deep // Warmup), or both.
Standalone mode analyses any folder of music — drag it in and Crate Control works out the BPM, key, beat grid and waveform itself, then runs the same AI passes and cue detection. The result exports as a rekordbox XML you can import. Your files are only referenced, never copied or modified.
The finished library — artwork, waveforms, BPM, key, energy and every tag on one grid, filterable by any of them. Click any field to edit it.
✨ Find similar — pick a track or a whole playlist and get your library ranked by fit, each match with a percentage and the reasons behind it.
try everything free for 14 days first
Browsing and the full AI analysis are free in both modes, forever. Applying to rekordbox, hot cues and XML export unlock with a 14-day trial — email only, no card — and after that with a one-time licence, no subscription. Nothing you analyzed is ever lost: it all applies the moment a key goes in. Licences work offline for weeks at a time, because gigs don't have wifi.
The licence key arrives by email the moment you buy.
Never. Everything Crate Control writes lives in rekordbox's own database — your files aren't touched, and the database is backed up before every Apply.
No — the AI models run entirely on your Mac. Matching sends only search text and acoustic fingerprints to the catalogues that answer them (Beatport, AcoustID, iTunes).
Nothing is written until you press Apply, and everything is reviewable and editable first. By default only empty fields are filled, so your own tags are never overwritten — and every write backs up the database first, restorable from inside the app.
It's a personal licence — use it on the Macs you own. There's no device lock to fight with.
