Scripted special effects & pyrotechnics

Sensors, pneumatic mechanisms, pyrotechnics,
water effects: hyper-interactivity.

At Chronix, a special effect is never gratuitous. It heightens an action, supports a narrative moment or reacts live to a gesture — from the audience, an actor, a mechanism. That philosophy is what we call hyper-interactivity.

From real-time interactivity — sensors, triggers, synchronisations — to scripted pyrotechnics, water-soluble confetti and water effects: every effect is designed and developed by our own team and operated by us, in strict compliance with safety regulations, so that the technology disappears behind the emotion.

Our signature

Our hyper-interactivity: what nobody else does quite the way we do.

Hyper-interactivity is the technical spontaneity we create between theatrical actions (a gesture from an actor or from the audience, the sensing of a mechanical action) and their technical consequence (sound effects, lighting effects, mechanisms).

We call these actions "augmented actions": augmented by technical means. And it is through hyper-interactivity that these effects heighten the action — the technology feels so natural that the audience never notices it.

"When the technology disappears behind the emotion, we know we have won."

Our special effects & pyrotechnics

All our families of scripted effects

Interactive effects, pyrotechnics, water-soluble confetti, water effects. Designed and developed in our workshop, integrated into your control system via Art-Net/DMX, OSC or MIDI, and operated by our team on site.

Sensors and triggers

Passage, proximity, gesture, contact and motion sensors: we design and build the sensors specific to your project in-house.

Scripted pneumatic mechanisms

For theatrical effects that require physical movement: slamming doors, objects that move, mechanical surprises synchronised to the script.

Synchronised sound effects

Quadraphonic or multipoint audio, real-time triggers, integration with sound control systems (OSC, MIDI, digital audio).

Scripted lighting effects

Native integration with lighting control systems (Art-Net/DMX), dynamic variations linked to the sensors or to the run of the show.

Sensors for stage weapons

For live performances using stage weapons (blank fire), we have developed a sensor that synchronises effects (lighting, sound, pyrotechnics) with the firing. The illusion of a real shot.

Synchronised firing

Stage effects coordinated with the music, with the actors' gestures or with the run of your event. Art-Net/DMX synchronisation for perfect integration with your control system.

Water-soluble confetti

Water-soluble confetti cannons — handheld or as confetti machines — that dissolve instantly in water. Ideal indoors, on protected sites or for eco-friendly events.

Water & smoke effects

Water jets, misting systems, scented or coloured smoke: for carefully crafted atmospheric moods. Can be combined with lighting effects to enrich the image.

Conditions and safety

One obsession: safety

Regulatory framework

Every one of our pyrotechnic services is subject to a prior safety study.

Every one of our pyrotechnic services is subject to a prior safety study, to a declaration to the authorities where required, and is operated by our licensed team.

For safety reasons, our pyrotechnic services are not available for hire alone — they always include our team on site.

Case study

Le Village Hanté 2025

Halloween 2025 · Le Pays des Sources

A trail triggered by the visitors.

For this Halloween trail created for the Communauté de Communes du Pays des Sources, Chronix deployed a sound + light + effects + pneumatic mechanisms installation synchronised with the visitors as they passed through.

Each scene is triggered in real time, creating a progressive immersion in a horror atmosphere. The audience never perceives the technology — they simply live the experience.
