Helm DJ

Helm DJ is a desktop app for macOS and Windows. It listens to ProDJ Link on the local network and maps deck state onto the rest of the rig.

Note

Product docs will be migrated here from the existing per-product docs.

What it does

• Reads ProDJ Link — per-deck position, BPM, track metadata.
• Writes LTC and MTC (CoreAudio native on macOS).
• Writes MIDI.
• Per-deck timecode routing with L/R channel split.
• Fires cues on deck state: on-load, on-play, on-air, off-air, timeline.
• Track migration — duplicate, import, copy track data.
• Auto-updates via Tauri + Cloudflare Worker.
