Shader

A Shader element runs a live GLSL fragment shader — generated, animated visuals rendered on the GPU. Use it for VJ backdrops, motion graphics, plasma and particle effects, and audio‑reactive visuals that move to the music.

Add it: Add Element → Shader…, which opens the Shader Editor.

The Shader Editor​

The editor lets you start from a bundled preset or write your own code:

  • A preset list of ready‑made shaders (neon kaleidoscopes, cosmic plasma, cyber grids, particle swarms, audio VU bars, and more). Selecting one loads its code.
  • A code area where you can edit the GLSL or paste your own fragment shader.
  • Compile / Preview to render the shader live so you can see it before adding it.

When you accept, the shader becomes a card that renders continuously on whichever deck it's fired to.

Audio‑reactive shaders​

Shader cards have an extra audio‑in port. Wire a sound source into it — a clip's audio or a Master Audio Input (microphone/line‑in) — and the shader receives a live audio spectrum it can react to. Several built‑in presets (the "audio pulse", "VU bars", and "reactive wave" shaders) are designed to pulse and move with the sound.

See Audio nodes for how to wire audio into a shader.

What it can do​

  • Generate endless looping visuals with zero source footage.
  • React to live audio for music‑driven backdrops.
  • Transform and position on a canvas, or run full‑screen as a background under other layers.
