Fantasynth is a real-time 3D visual instrument. It is built for musicians, visual artists, and performers who want to mix beat-synchronized visuals live.
The project explores what a visual instrument can be when there is no install, no plugin, and no license to manage. Open a URL and play.
Compositions are plain JSON. Shaders are GLSL. The system is designed to be hackable and shareable.
Fantasynth is made by HelloEnjoy, a small studio working at the intersection of music, code, and visuals.
Fantasynth is free to use and non-commercial. There is no signup, no account, no telemetry. Visit live.fantasynth.com to launch the instrument, or read the documentation to learn more.
