About Sonic Pi

Sonic Pi turns writing code into a way of making music. You type short programs that play notes, chords, samples and synths, then change them while they run, which makes it usable both as a composition tool and as an instrument on stage. It was created by Sam Aaron and is widely used in schools to teach programming through music, but working musicians and DJs also use it for live-coded sets. The syntax is simple and Ruby-like, with live loops, built-in effects, scales and a large set of documented synths. The desktop app can talk to other gear and software over MIDI, OSC and Ableton Link, and handles low-latency audio through your audio interface. A newer web version runs in the browser, though with fewer connectivity features than the desktop app. Sonic Pi is free and open source, with no paid tier, and runs on Windows, macOS and Linux as well as the web. It is the friendliest starting point among live coding tools, while pattern languages like TidalCycles suit people who want denser, more abstract rhythmic code.

Best for: Students, teachers and musicians who want an approachable way to compose and perform music with code.

Pros and cons

What works

  • Very beginner-friendly syntax with a built-in tutorial
  • Live loops let you change music while it plays
  • MIDI, OSC and Ableton Link support in the desktop app
  • Free and open source on every major desktop OS

Why people leave

  • Web version lacks OSC, Ableton Link and low-latency audio
  • Not a replacement for a DAW's mixing and arrangement tools
  • Pattern-heavy styles are terser in TidalCycles or Strudel
