Snare 02
The signal follows 2 parallel paths.
Path 1: Noise to VCF, to VCA-A.
Path 2: The oscillators bypass the VCF, going from the ring mod to the LFP, and then bypass the VCA, going to main 2.
Envelope A modulates oscillator 1 FM. This simulates the pitch sweep effect created when a snare’s heads stop vibrating at different times.
