LeTissier Design & Media — independent studio, Ireland
Open-source software for live production — lighting control, realtime visuals, LED walls, crew comms, and the signal path between them. Built for festival conditions, free on GitHub.
The studio’s current work, laid out like the patch sheet it would live on. Every channel is open source — follow a row to its product site or straight into the code.
The look engine for Resolume
Sits between Arena's clip grid and the lighting network. Looks fire from clips, effects follow the BPM, and a Rust core renders it all to Art-Net at 40 Hz — with 2D/3D previz and native MIDI, so it keeps running with the window closed.
Generative visuals, played live
A native Rust + wgpu instrument for VJing: morphing geometry, strange attractors and live point clouds run through cosine palettes and a feedback chain, published zero-copy over Syphon and NDI — driven by OSC, MIDI, audio analysis and a node graph.
Crew comms in one box
Offline-first communication for temporary events: channels, DMs, files and push-to-talk voice, plus patch-sheet and lighting modules — served from one box on your own Wi-Fi with zero internet dependency. Messages queue in an outbox and survive dead phones, roaming and reboots.
Codec damage as an instrument
Datamosh for Resolume as native FFGL plugins — an effect and a mixer that estimate motion in real time and break it on purpose: melt, bloom, pixel drag, and a Damage group for getting it wrong beautifully. Signed, notarised installers for macOS and Windows.
Faces to NDI, live
Points a camera at a crowd, finds and follows faces, and streams the result to your vision mixer over NDI — stable track numbers, optional expression labels, a browser control panel. Detection only: it never identifies anyone and stores nothing.
Speaking NovaStar
How NovaLCT and VMP actually control NovaStar LED processors — a documented protocol investigation, plus the working control layer a third-party app needs. Operators work in named screens, not IP addresses, and a blackout confirms before it sends.
Patch sheets, local-first
CRDT patch sheets for live production — channels × artists on any phone or laptop, fully offline, merging without conflicts whenever a relay appears. Since folded into Crewbox as its patch-sheet module; the original still stands alone.
Folded into CH 03 — Crewbox
Classified, for now
First commit landed August 2026. A name, a licence and a hunch — the newest thing on the bench. Watch this channel.
The reasoning behind the tools — what a show needed, what broke, and what shipped. Entries cite the actual pull requests and releases, so the record stays checkable.
LeTissier Design & Media builds software for the places where software usually gives up: festival sites, temporary networks, front-of-house at 2 a.m. Everything on the patch above exists because a show needed it — then got documented, signed and released, because the next crew shouldn’t have to solve the same problem twice.
The studio takes commissions across the same territory: show tooling, plugins, control systems, design and media for live events. If it speaks DMX, NDI, OSC or MIDI — or should — it’s in scope.
Every studio needs one. Ours is WebGL: a three-chapter camera ride around a floating sculpture, built with React Three Fiber. It follows your pointer, respects reduced motion, and goes easy on phones.
Commissions, collaborations, support on any of the tools above — or a rig that needs something that doesn’t exist yet.
