AR Envelope Generator

+/-12v 9v analog

This was the first envelope generator I’ve built. It has attack and release controls.

My demo:

Schematics

This was originally based on Nathan Ramsden’s OpAmp AR build.

Schematics for the AREnvelopeGenerator

This version of my schematics is from my latest prototype which uses +/-12V power, but originally I built this for 9V and GND. Swap out 12V with 9V and -12V with GND. It should work just fine.

Let me know if you’ve built it! Tag me on IG @benjiaomodular.
