cdj

The bridge between Pioneer CDJs (Pro DJ Link) and apps that play along with them: a Mac menu-bar app and a Linux tray app, built on Deep Symmetry's DJ Link research

Update rekordbox 6/7 playlists in place from M3U/M3U8 – only changed tracks, keeps cues & beatgrids, no full USB re-sync. macOS & Windows CLI + drag-and-drop.

Batch-fixes embedded MP3 album art so covers display correctly on car stereos, USB players, and DJ gear. Resizes to 500px and converts PNG covers to JPEG. Built for Pioneer, works with most players that read embedded art.

Download best-quality audio (YouTube / YT Music / SoundCloud), transcode to FLAC, and tag it — a DJ crate builder that runs as a oneshot container on a Raspberry Pi.

Copy the playlists on your rekordbox USB to a folder on your computer — every playlist becomes a folder with its songs. Adds new songs only, never overwrites. Mac & Windows, runs in your browser.

Your music library on a USB stick every Pioneer/AlphaTheta deck reads natively — no Rekordbox. Analysis, beatgrids, cues, waveforms, artwork, both device database formats.

Il programma rimuove l'autore dalle canzoni (se il formato è come segue: `AUTORE - TITOLO`) semplificado la visualizzazione del titolo da alcuni dispositivi come lettori musicali con display limitato come quelli da DJing datati.
