I’m writing a SuperCollider program based on Xenakis’ description of granular synthesis in Formalized Music. My program has a graphical interface very similar to UPIC. The working title for this program is GrainPIC. This piece is generated by a prototype of this program and is a proof-of-concept. Xenakis envisioned cloud synthesis with only sine wave grains, so the prototype only supports sine grains, however, I expect to change this shortly.
