SuperCollider Wrapper for Blender's Custom Python Nodes. License: GNU GPL 3.
SoundPetal is a thin wrapper around SuperCollider 3 Ugens. Most of the node UIs are inherrited from the SoundPetalUGen SuperClass. Ugen classes are defined by succintly passing their name and arglist to core.node_factory.make_ugen_class.
Certain nodes are not generated this way, like in, out, and Make SynthDef, these have dedicated node Class definitions because their UI interface is sufficiently different.
