One-pass migration from Engine DJ m.db into Mixxx mixxxdb. Crates and folder-based browsing preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from Engine DJ to Mixxx normally means an XML round-trip: export from Engine DJ, hope Mixxx parses it correctly, manually rebuild crates and folder-based browsing, discover cues didn't translate. Engine DJ versions 2.x and 3.x changed the schema — tools written for one version often miss data on the other. And on the destination side: Mixxx supports its own crate format that doesn't map 1:1 with playlists — writers have to choose which model is the target.

Engine DJ and Mixxx speak completely different languages: Engine DJ m.db (Engine DJ libraries live on the player USB/SSD itself as a per-drive Engine Library folder, not just on the home machine) versus Mixxx mixxxdb (Mixxx is open source and free, so it's often the destination for DJs leaving paid apps — but the migration tooling around it is thin). XML export-import is the usual bridge — and it's lossy on both ends. MLD treats both formats as first-class, reads Engine DJ's structure natively, and writes Mixxx's native format directly, so crates and folder-based browsing survives and the target app doesn't re-import anything. A timestamped backup of each app's library is taken before any write.
Yes. MLD reads both libraries locally, so both apps (or at least their library files) must be accessible on the same computer. Nothing uploads anywhere — all scanning is local.
Yes. MLD reads playlist groups, smart playlists, history sessions and writes crates and folder-based browsing natively so the structure survives the migration.
Run Fix Missing Tracks for Engine DJ first. MLD scans your drives, matches moved/renamed files, and repairs links in Engine DJ before the transfer — so Mixxx receives a clean library.
Yes. Engine DJ and Mixxx libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the Mixxx to Engine DJ guide. MLD supports every direction between supported apps.
Yes. MLD tracks Engine DJ version compatibility and updates with each new release. See the changelog for the version matrix.
Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
