Show Design Software

Compose your haunt.
Down to the millisecond.

A browser-based timeline for haunted attractions. Design scenes where multiple skulls talk, DMX lights shift, fog fires on cue — then push the whole show to your Vox Master with one click. No laptop required at showtime.

What it does
🎙️

Automatic jaw sync

Drop a .wav file onto a skull track. Vox Composer reads the waveform and builds jaw keyframes from the audio automatically — no manual work.

📡

Vox-Link wireless

Sub-millisecond sync to every remote. No router, no infrastructure. Works in barns, warehouses, and outdoor haunts with zero setup.

💡

DMX, relay, and pixels

Every output on every device gets its own timeline track. Lights, fog, relays, NeoPixels — all firing at the exact millisecond you placed them.

🔌

Plugin architecture

Add WLED, Home Assistant, OSC, projector control, or any custom integration. Open plugin spec means the community can build what you need.

✈️

Works offline

Designed your show at home? Vox Composer caches itself as a PWA. Open it in your warehouse with no internet and it works exactly the same.

🔁

Push media to remotes

No manual SD card copying. Sync your show's audio files directly to each skull remote over WiFi from inside the app.

Your hardware never depends on our server

Vox Composer is open source. If REHMLIGHTS ever shuts down, you can run it locally on your own machine — forever. The Vox Master can also host a basic show management portal on your local network, so your haunt keeps running no matter what. One price. No subscriptions. No lock-in.
