One-pass migration from djay Pro JSON library into Mixxx mixxxdb. Crates and folder-based browsing preserved end-to-end, format gotchas handled on both sides, nothing leaves your machine.
Moving from djay Pro to Mixxx normally means an XML round-trip: export from djay Pro, hope Mixxx parses it correctly, manually rebuild crates and folder-based browsing, discover cues didn't translate. djay Pro syncs library data through iCloud on Mac, which means the canonical library may live in a hidden iCloud Drive folder rather than the local app support folder. 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.

djay Pro and Mixxx speak completely different languages: djay Pro JSON library (djay Pro integrates tightly with Apple Music and Spotify streams alongside local files — tracks that came from a stream have no portable file path) 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 djay Pro'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 playlists and collections and writes crates and folder-based browsing natively so the structure survives the migration.
Run Fix Missing Tracks for djay Pro first. MLD scans your drives, matches moved/renamed files, and repairs links in djay Pro before the transfer — so Mixxx receives a clean library.
Yes. djay Pro and Mixxx libraries are both copied to timestamped backups before any write. Rollback is always one folder away.
Yes — see the Mixxx to djay Pro guide. MLD supports every direction between supported apps.
Yes. MLD tracks djay Pro 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.
