GHz Labs - Quad AR Envelope Generator

A simple analog quad AR envelope generator. With gate inputs, attack and release controls. Two of the inputs are normalised together to conveniently generate multiple CV outputs with the same gate input. Can be utilised also as a slew limiter or envelope follower.
Each channel can be configured to have a different overall response length by using various capacitor values.

Easy to build, 0805 components great for SMD beginners.
