Glycerin is an FM Synth created within Ableton's Sampler instrument using waveforms by Adventure Kid. I tried to cram in as many features as I could while still keeping it somewhat simple without losing expression. Glycerin is all about having fun and weird experimentation! It can do quite a lot so have an open mind!
Glycerin comes in two flavors (I and II). I uses linear envelopes while II uses sloped envelopes.
