Other Libraries

cl-patterns is a music sequencing library for Common Lisp. It is heavily inspired by the Patterns system in SuperCollider, but aims to improve upon it. A few notable differences are:

• More consistent argument order. SuperCollider patterns:

  Pseq(list, repeats)
  Pstutter(repeats, pattern)
  

  cl-patterns:

  (pseq list repeats)
  (pstutter pattern repeats)
  

• More introspectable and configurable.
• Differing terminology: a SuperCollider pattern generates a Stream of results, while a cl-patterns pattern generates a pstream of outputs.
• cl-patterns supports additional backends; for example, it can be used with SuperCollider/cl-collider, but it can also be used with Incudine.

See cl-patterns' sc-differences.org for more ways it differs from SuperCollider's patterns.

Incudine is a music and digital signal processing programming environment for Common Lisp. It is similar to SuperCollider in that it is a real time audio synthesis server with a large feature set, however it also differs from SC in several ways. Here are a few examples:

• Designed from the start to be used with Common Lisp.
• Allows user-definable "virtual UGens" to be written in Common Lisp. cl-collider supports "embeddable synthdefs" functionality, which is similar.
• Differing terminology: for example, what SuperCollider calls "SynthDefs", Incudine calls "DSPs".
• Built-in LV2 (Linux audio plugin) support.
• Built-in LADSPA (Linux audio plugin) support. SuperCollider requires the sc3-plugins package to be installed for this.
• Built-in FluidSynth (soundfont) support.
• GPL 2.0 license instead of GPL 3.0.
