A ready-to-play rekordbox USB for your XDJ-RX3
The XDJ-RX3 gives you the CDJ layout without the laptop — as long as the USB is prepared right. Alpha does the preparation: it analyzes your music, sequences it harmonically along the arc you choose, and writes the rekordbox library the RX3 reads straight from the stick.

What Alpha writes for the XDJ-RX3
Alpha writes a full rekordbox USB the player reads directly: the classic export.pdb library every CDJ and XDJ has read for years, the newer encrypted exportLibrary.db the latest players prefer, the per-track analysis files with beat grid, cues and waveforms, album artwork, and the audio under Contents/<Artist>/<Album>. No rekordbox software is needed anywhere in the chain — the stick plugs straight into the gear.
The beat grid is built from the interpreted BPM, so tracks arrive beat-ready and the player does not re-analyze anything. One limit to know: Alpha writes one constant beat grid per track, so tempo changes inside a track are not modelled.
The RX3's 10.1-inch touchscreen browses the rekordbox library on the stick — which Alpha writes in full: both database formats, beat grids, waveforms, artwork and your playlist in set order. Two USB ports mean two DJs can each bring their own Alpha-prepared stick and hand over without a pause.

Good to know on the XDJ-RX3
- Two USB slots: back-to-back sets work with two prepared sticks side by side — each DJ browses their own library.
- The RX3 reads FAT32, exFAT and HFS+ — but firmware update files still have to come on a FAT32 stick.
- The RX3 re-analyzes nothing; Alpha's beat grids and waveforms load instantly from the ANLZ files.
- rekordbox export is a new target — please confirm it on your own gear before a gig.
Common questions about the XDJ-RX3
Do I need rekordbox installed to prepare a stick for the XDJ-RX3?
No. Alpha writes the rekordbox library and analysis files itself — the RX3 reads the stick exactly as if rekordbox had exported it.
Can two DJs use both USB ports with Alpha sticks?
Yes — each port reads its own rekordbox library independently, so two prepared sticks make a seamless handover.
What drive format does the RX3 want?
FAT32, exFAT and HFS+ all work for music. Keep a FAT32 stick around anyway — firmware updates only load from FAT32. Alpha writes onto the stick's existing filesystem and never reformats.
Does the RX3 have an SD card slot?
No — unlike the CDJs, the RX3 is USB-only. Both ports read the same rekordbox library Alpha writes.

Every feature is in the free download — analysis, harmonic sequencing, loudness matching and the rekordbox USB write. It stops after 10 tracks, which is enough for one real set on your own stick. After that it's €30 including VAT, once. No subscription.
