Welcome to SuperCollider!

Build Status Appveyor | Join us on Slack

SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It is free and open source software available for Windows, macOS, and Linux.

SuperCollider features three major components:

  • scsynth, a real-time audio server, forms the core of the platform. It features 400+ unit generators ("UGens") for analysis, synthesis, and processing. Some of the audio techniques it supports include additive synthesis, subtractive, FM, granular, FFT, and physical modeling. You can write your own UGens in C++, and users have already contributed several hundred more to the sc3-plugins repository.
  • sclang, an interpreted programming language, controls scsynth via Open Sound Control. You can use sclang for algorithmic sequencing, connecting your app to external hardware including MIDI controllers, or writing GUIs and visual displays. sclang has a stock of user-contributed extensions called Quarks.
  • scide is an editor for sclang with an integrated help system.

SuperCollider was developed by James McCartney and originally released in 1996. In 2002, he generously released it as free software under the GNU General Public License. It is now maintained and developed by an active and enthusiastic community.

This README is the first help for anyone new to SuperCollider. There are many good resources available for learning SuperCollider, with up to date links from the site listed above, including links to forums and mailing lists.


SuperCollider consists of three separate components:

  1. scsynth or supernova - audio engine (the "server")
  2. sclang - programming language runtime interpreter including Qt graphical user interfaces
  3. IDE (integrated development environment) - an editor for writing code and running supercollider

To begin using SuperCollider, you usually start up the IDE:

  • on Mac OS this is
  • on Linux and Windows, this is the scide executable

You can get further help by using the IDE's integrated help, a system which can be invoked via the "Help" menu or using the key combination Ctrl+D (on Linux, Windows) or Cmd+D (on Mac OS). In the Help menu, you will also find an action that will take you directly to the help page on using the IDE.

When starting the SuperCollider IDE, the audio server is not started automatically. You can start it using the "Language > Boot Server" menu action, or using the key combination Ctrl+B (on Linux, Windows) or Cmd+B (on Mac OS). This is just to remind you in case you're impatient and can't understand why you're not immediately getting sound.

We suggest you proceed by reading the tutorials available in the help system. Please note that some help pages are not up-to-date with the latest development of SuperCollider, especially when mentioning the code editing environment. Regarding this, it is best to refer to the help page specifically about the new SuperCollider IDE.

Also, please explore the IDE menus, which will let you discover a lot of the functionality of the coding environment.

We hope you enjoy SuperCollider; please get involved in the active community!
