I recently started these videos on Supercollider in order to share some of my design recipes. If you interested: here are the links to first three:
Pulsar synthesis with GrainSin
FM: N modulators, 1 carrier
Pulsar synthesis with GrainFM
These tutorials are not beginner level. It’s assumed that viewer knows basics of SuperCollider language. Not an academic style, put from a musician’s point of view with connection to musical application. Hope they will be usefull.
