What you need
- Players and mixer by cable on one switch, router or the DJM’s LINK sockets. See setups compared.
- Tracks on a USB stick or SD card exported with rekordbox (export mode, tracks analysed).
- Every player its own player number: on the player *Utility → Player No.*
- No rekordbox on the computer that runs LJ Link.
Step by step
Connect all players, the mixer and the computer by cable. Switch Wi-Fi off on the computer.
Check the player numbers: 1, 2, 3, 4, each only once. The mixer channel of each player should match its number, otherwise ON AIR shows the wrong deck.
Start LJ Link → Search automatically. Within a few seconds every player appears, the mixer shows up in the Mixer tab.
Load a track. Title, cover and waveforms arrive; with several players this can take a few seconds.
Info
LJ Link joins the network as a virtual player with its own number, like other Pro DJ Link programs do. It only listens and sends no sync, master or tempo commands.
Limits of Pro DJ Link
- Faders and EQ: no DJM sends them. The blue bar only shows on air or off.
- ON AIR also needs sound at the master output and matching channel numbers.
- Position on NXS2 and older: they report only between beats. LJ Link runs them at their pitch, so the waveform moves smoothly; after a cue or loop there can be small jumps. Scratching is shown only roughly.
- Streaming tracks (Beatport, SoundCloud, TIDAL …), CDs and never analysed files have no waveform data.
- CDJ-3000 with new firmware: if a stick from an older rekordbox shows no waveform, export it again with rekordbox 6 or 7.
Problems
A player appears twice
- Wi-Fi and cable in the same network: switch Wi-Fi off.
- Two players with the same number, or LJ Link started twice.
- Virtual adapters (VPN, Parallels, VMware, Docker): switch them off.
“No track loaded” or no waveform
- Update to LJ Link 1.4.1 or newer.
- Track from a rekordbox export? Streaming and CD have no data.
- rekordbox on this computer? Quit it.
Yellow note “Beat port 50001 is in use”
rekordbox, Beat Link Trigger, SoundSwitch or a second LJ Link listens for beats. Close it and search again. Until then positions are estimated.
