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.
