Pro DJ Link · MIDI · OSC · Art-Net · sACN · Ableton Link

Wire the booth to everything else.

The players are already broadcasting beats, track loads, cues, phrases and master status across the LAN. Sync Latch listens, and turns any of it into MIDI, OSC, lighting and clock — through a trigger graph you draw yourself.

How it works

From a beat on the network to a cue on the rig

Sync Latch reads the Pro DJ Link traffic already on the LAN and normalises it into one typed event stream. Nothing is patched into the players, nothing is installed on them, and no cable leaves the booth that was not there before.

Capabilities

A show controller that starts from the music

Every part of it is built around the same event stream, so a rule that fires a MIDI note and a rule that runs a lighting chase are the same three nodes with a different action on the end.

Live Pro DJ Link

Players and mixers discovered on the network, with beats, tempo, track loads, memory and hot cues, rekordbox phrases and master status normalised into one event stream.

Visual trigger graphs

Wire an input to a filter to an action and watch it fire. Several graphs per project, each armed on its own switch, and a simulate control that proves a chain without a deck in front of you.

MIDI, OSC and HTTP

Notes, CCs and OSC messages with typed arguments, including ready-made address trees for Resolume and grandMA3, dispatched through a router that validates every action before it leaves.

Lighting that follows the music

Fixture profiles, patching and groups, scenes and chases, and live Art-Net and sACN output. Import a real patch straight from a grandMA3 over MVR-xchange.

Clock, Link and timecode

Publish the master deck's tempo as an Ableton Link session for the rest of the network to follow, and generate SMPTE over LTC, MTC, Art-Net or TCNet from the same clock.

Play history and remote view

Every played track recorded and exportable as CSV or JSON, and a read-only web view of the current state for anyone on the network who needs to watch rather than touch.

Pricing

Pick the tier that matches the rig

Free is not a demo. Live Pro DJ Link ingestion, the deck monitor, the graph editor and an outbound Ableton Link session are all in the base entitlement — the paid tiers open the outputs and lift the rule ceiling.

Free

The whole signal path, three rules deep

£0/ month

Live Pro DJ Link ingestion on real CDJs, the deck monitor, the graph editor, and an outbound Ableton Link session. Nothing about the input side is held back.

Download Sync Latch

One installer per platform, and the free tier is the same binary — activate a licence when you need the paid outputs, not before. A published version is never rewritten in place, so the file you download today is the file you can verify tomorrow.

Pro DJ Link capture on Linux needs libpcap; the .deb and pacman packages declare it as a dependency.
