Hexa documentation

Hexa is a browser-based, audio-reactive visual synthesis tool for live performers. It stacks shader effects on top of looping video inside a single canvas, driven in real time by the music.

These docs cover how the system works and the building blocks you compose into a show.

Where to start

• FX layers — every effect, searchable and filterable by category, with icons, previews, parameters, and audio behaviour.

Core ideas

• Effects run as a chain. Each effect sees the output of the one before it, so order is part of the look.
• Most controls are audio-aware. A resting Base value, an Audio depth that the synced band pushes on top, and an optional Trigger that fires on hits.
• Scenes and playsets are savable. Build a chain, save it, recall it live.
