LJ-LinkVJ-Link and LJ-Link
The DJ's music drives the visuals.
LJ-Link is the sister project: it reads Pioneer CDJs (Pro DJ Link), Denon Prime (StageLinQ) and Serato and shows the lighting jockey every deck with waveform, cues and BPM. VJ-Link takes from it what the visuals need, so lights, visuals and music run in one beat without anybody tapping.
What VJ-Link gets from LJ-Link
| Data | What VJ-Link does with it |
|---|---|
| Tempo and beat phase of the master deck | the clock of all visuals, effects, strobes, loops and transitions; the beat lands exactly on the kick |
| Phrase changes | scenes with “next on phrase change” move on when the track changes its part (Auto on) |
| Track change | shows the Now Playing lower third for 8, 15 or 30 s |
| Title, artist, cover | the clip Now Playing (empty in LJ-Link's privacy mode) |
| Waveform and position | the clip DJ waveform, scrolling like on the player |
| Bass, mids, highs | drive audio visuals and modulation without a microphone |
Back to LJ-Link VJ-Link reports its scene, blackout, master, BPM and tempo source; Open LJ-Link under CONNECT opens LJ-Link's web interface.
Connecting
Nothing to set up: VJ-Link finds LJ-Link on the same computer and in the network by itself (Bonjour) and connects. The LJ-LINK pill at the top turns green, CONNECT shows the decks. Only if LJ-Link runs in another network, enter its address or address:port under CONNECT → LJ-Link.
| LJ-Link | What works | Status |
|---|---|---|
| 1.7.7 | everything: tempo, beat phase, phrases, decks, titles, waveform | Tested |
| older | through its web interface: tempo, decks, titles, track changes; no beat phase and phrases | Built |
Scenes on the phrase
Build your scenes (for example Intro, Build, Drop, Breakdown).
Pencil on each scene → Afterwards: next on phrase change.
Switch Auto on. Every time the DJ's track starts a new phrase, VJ-Link moves on to the next scene, with the scene's own transition.
Tip
The desk can take over at any time: a scene from the desk or a pad wins, Auto goes on from there.
Club rules with Auto
With Auto on, VJ-Link also follows these fixed rules from the master deck: chorus → scene named „Drop“, up → „Build“, down and outro → „Ambient“, hot cue C → strobe for 4 beats, loop on → effect 1 of layer 2 to 80 %. A rule only fires if a scene with that name exists. With Auto off, the desk alone decides.
