The media-sound/supercollider package provides three binaries:

  • sclang, the interpreter for the SuperCollider language. An interactive session can be started from the command line via sclang; a server can be started via sclang -D.
  • scide, the IDE. An introduction to its use can be found in the " Getting started with SC" tutorial.
  • scsynth, a SuperCollider synthesizer.

There are no man pages for these binaries, but command-line options for sclang and scsynth can be listed by passing the -help option to either.


Although SuperCollider provides an Emacs Lisp interface to the SuperCollider system, via the inclusion of scel, scel has not been updated since September 2021. Additionally, the sclang-extensions Emacs package, available via MELPA, has not been updated since May 2016, and is listed as unmaintained. Both might or might work adequately, depending on system configuration and use-case. In particular, note that starting an sclang server via sclang-start might result in issues, due to the command-line options -iscel being hard-coded in sclang-interp.el.

To make scel available in Emacs:

(add-to-list 'load-path "/usr/share/emacs/site-lisp/SuperCollider/")
(require 'sclang)
