Envelope Generator
Version 0.1 from September 2020
Here’s the first Envelope Generator (ADSR) that I built for my drum machine project. It’s based on “The Fastest Envelope in the West” by René Schmitz which is comparably easy to build and works awesomely! I modified and extended it a bit for my purpose (changed R and C values and added some peripherals).
Features
- ✅ Full stack envelope (attack, decay, sustain and release)
- ✅ Manual trigger
- ✅ 2 outputs (for e.g. VCO pitch and VCA)

Improvement Potential
Sustain is probably not 100% stable. You can hear it a few milliseconds after the tone starts (pitch goes down). Fortunately that’s not a show stopper for my drum machine project, because I mostly just need some decay and release.
