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
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.
CDJs and mixers discovered on the LAN
Inputs, filters and actions you wire yourself
Validated, gated, dispatched in priority order
MIDI, OSC, Art-Net, sACN and Ableton Link
Capabilities
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.
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.
Wire an input to a filter to an action and watch it fire. Every graph in a project is a tab with its own arm switch, and a simulate control proves a chain without a deck in front of you.
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.
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.
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.
A read-only web view of the decks and the night's tracklist for any phone on the network, transparent overlays of the waveforms and the graph firing for a video mixer, and every played track exportable as CSV or JSON.
The editor
Trigger Graphs takes the whole window: the project's graphs as tabs along the top, the canvas under them, and the trigger events and output monitor folded along the foot until you want them. It answers the moves node editors have made familiar.
Each graph in a project is a tab along the top with its own arm switch. Click a tab to edit that graph; right-click it to rename, duplicate, group or delete it.
Right-click
A node's settings are fields on the node, edited where it stands, with any problem it has marked on it. Fold it down to its title and ports once it is set.
Alt+C
Double-click empty canvas and type to add a node where you clicked. Drag to box-select, pan with the middle button, and right-click anything for the actions that fit it.
Double-clickRight-click
Take a node out of the chain and leave it wired: whatever reaches it passes straight on, until you put it back.
Ctrl+B
Pack a run of nodes into one, with the wires that crossed its edge as its ports and the settings you choose shown on it. Save it to the library and drop it into any graph.
Ctrl+G
One press lays the graph out left to right, every wire level from port to port and nothing overlapping, and frames it clear of the canvas's own controls.
Pricing
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.

Planned — specified in the licensing model, not yet shipped. Nothing on this page is sold on it.
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.
