A SuperCollider client for CommonLisp.
It is an experimental project, so changes to the API are possible.
- tempo-clock on cl-collider
- cl-collider on Windows10
- Tutorial - Due to API changes, this video is deprecated. A new tutorial video is coming soon.
- Live Coding Demo 1
- Live Coding Demo 2
- SuperCollider - compatible with 3.9 and 3.8.
- Quicklisp
- ClozureCL or SBCL or ECL
If you have your own additional libraries, please report me. I will add here.
- sc-extensions - extension library
- cl-patterns - patterns/sequencing library
- package:
sc,sc-user(use this package) - named-readtable:
