Liquid LSD

Liquid LSD is open-source VJ software for real-time, audio-reactive visuals. It drives generative shaders and procedural geometry from a live audio feed, runs everything through an analog-style modulation matrix, and gives you a fast keyboard-driven performance interface for playing it live.

It's in active beta — the core workflow is solid and usable, and the docs here aim to help you get comfortable with it as quickly as possible.

Getting your bearings? Your Workspace explains the layout, the four decks, and how everything connects.

User Guide

  • Your Workspace — The layout explained: four decks, the mixer, signal flow, and the two main modes.
  • Visual Sources — The built-in generators (Mandala, Icosa-Dodeca, Gyroid, and more), the FX chain, feedback loops, and how to load your own ISF shaders.
  • Modulation — How to wire audio, LFOs, sequencers, and MIDI to your visual parameters using the CV grid.
  • Presets & Library — Saving and loading presets, building setlists, the Auto-VJ queue, and MIDI mapping.
  • Output & Recording — Sending video to projectors and other apps, recording your set, and exporting high-quality renders.
  • Performance Controls — MIDI and OSC/TouchOSC hardware control mapping, the trackpad performance surface, custom notes, and tooltips.
  • Hardware Control — which controller path to use: the Midi Fighter Twister, other MIDI controllers, or OSC/TouchOSC, with quick starts.
  • Macro Controls & the Perform View — Assigning targets to macro knobs with Learn Mode, and performing with the 4×4 macro knob matrix and Edit.
  • Web Broadcast — Live-streaming visual parameters to a browser-based visualizer. (Experimental — requires a relay server.)
