THE PITCH

Every phone in the venue, lit in lockstep with the show.

Pulse is a realtime crowd-lighting platform for live events. Audiences open a URL — no app install — and their phones become a single, addressable pixel grid that the operator (or the lighting console) drives in sync with the music, the speech, the moment.

Hundreds of synced phone torches, colour washes, strobes, branded reveals and timecode-locked light cues — all from a single phone-first operator console.

HOW IT WORKS

Three moving parts. No infrastructure on the venue side.

Operator → Pulse server → Audience phones, with grandMA3 integration

Operator — phone-first GUI. LIVE tab for busking, PROGRAMMING tab to build cues, SHOW tab for timecode + standby + countdown takeovers.
Pulse server — multi-tenant Node.js + Socket.IO. Per-event keys, per-event feature flags, audience analytics built in.
Audience — one URL. Phones join a live socket room and react instantly to whatever the operator fires.

NEW · grandMA3 INTEGRATION

A single GO fires both worlds.

Drop a one-file Lua plugin into your Pulse plugins folder and any cue command line can fire a Pulse cue alongside the lighting cue.

Lua "PulseFire('drop')"

Phones flash red, lasers fire, audience gasps. Same beat. Every time.

WHERE IT FITS

Built for live events that already think in cues.
