Live Coding — Strudel

What is Strudel?

Strudel is a live coding music environment that runs entirely in your browser. Write patterns in JavaScript-flavoured syntax, hit Ctrl+Enter and it plays. Change the code while it runs — the music changes instantly. No install. No setup.

It's the browser port of TidalCycles — the live coding language built for exactly this kind of DnB / acid / club music. Perfect for KentSt.FM jingle sketching, pattern experimentation and general sonic mischief.

Patterns below open in a new Strudel tab with the code pre-loaded. Edit live. The College of the Rats recommends headphones and a beverage.

Strudel live editor — edit code and press Ctrl+Enter to play · powered by strudel.cc
