Features

Everything your DJ library needs.

Built from scratch for the way DJs actually work — not the way software engineers think they do.

Library & Search
2,600+ tracks unified from every drive and folder. Search instantly by artist, BPM, key, genre, or format. Filter by tempo range with a single click.
2,600+ tracks · instant results
Play History
Every session you've ever played. Read directly from your USB drive without Rekordbox — no sync, no export, no waiting. Plug in and go.
Reads PDB format natively
Recorded Sets
183 recordings. 275 hours. M13 identifies which session matches each recording by duration, then lets you save or copy the tracklist in seconds.
Auto-matched tracklists
All Formats
AIFF, MP3, WAV, FLAC. Including AIFF seeking support that nothing else gets right — no more jumping to the wrong position mid-track during previews.
AIFF · MP3 · WAV · FLAC · M4A
Library Locations
Every drive, every folder, one library. Add as many locations as you like — internal, external, archive — and M13 keeps them unified. Unplug a drive and those tracks are marked offline, not lost.
Unlimited folders · offline-aware
Crates & Sessions
Build a crate for a night, a room, a mood. Then save the whole working state as a Session — filters, scope, set in progress — and pick it up exactly where you left it, days later.
Save state · resume anytime
Scope
Narrow the entire app to one folder with a click. Search, filters, browsing — everything answers from just that crate of music. Clear it and the whole library is back.
One folder · whole app follows
Your Columns
Show what you use, hide what you don’t, drag them into the order your eye expects. BPM and key first, or artwork and folder — the table is yours, and it remembers.
Show · hide · reorder
Day & Night
Prep in daylight, play in the dark. A full light mode — Auto, Sun or Moon — with every colour re-measured so nothing fades on a bright screen. Even Ambient gets its own Sun look.
Auto · Sun · Moon
My Collection
Your personal music, right beside your DJ library but never mixed into it. Browse by artist or album, keep your ratings and play counts, and move a track across when it earns its place.
Two libraries · one app
Harmonic Sets
Every transition in your set is marked — same key, relative, one step round the wheel, or a clash. Arrange reorders the set in a click. Fix finds the track that bridges a clash.
Mark · Arrange · Fix
Brand Artwork
Stamp your logo on tracks with no cover, or replace a pool’s branding image. M13 spots pool artwork by finding it across different albums — you choose what gets replaced.

432hz Suite

The only DJ library
that knows how your
music is tuned.

Most of the world masters to A=440. Some of it doesn’t. M13 tells you which is which, shifts it live while you listen, and converts it permanently when you’re sure.

432 Hz A TUNED DOWN 31.8¢ OFF 432 440
01
Detect
M13 analyses each track and flags what it’s actually tuned to — so you know before you play it, not after.
02
Shift
Flip a switch and hear any track at 432 in real time. Pitch moves, tempo doesn’t. Nothing is written to your files.
03
Convert
When you’re sure, convert for keeps — new files, tags and artwork intact, originals untouched. Ready for the USB.
Ambient Mode

Press Ambient.
Your screen becomes
a living hi-fi console.

One keystroke hides the interface. What remains is the clock, the artwork, and the music. A screen worth leaving on.

How it works

From USB to tracklist in under a minute.

No Rekordbox required. No cloud sync. No subscription. Your data stays on your machine.

01
Open your music folder
Point M13 at any folder — a USB drive, a NAS, your local library. Or click "Scan from Rekordbox" to pull in every track Rekordbox already knows about, instantly.
02
Plug in your USB
M13 detects the drive automatically. It reads the PDB database directly — no export needed. Your play history appears immediately: every session, every track, in play order.
03
Match your recordings
Switch to the Sets tab. Every recording from your REC folder appears with its duration. Click "Match History" and M13 finds the session that fits — then you save or copy the tracklist.
04
Search, preview, tag, export
Search across your entire library by any field. Preview any track with accurate AIFF seeking. Tag sets with names and notes. Export a full catalogue to CSV whenever you need it.
