Collude

Envelope follower & amp

discontinued - replaced with https://www.nonlinearcircuits.com/modules/4hp-envelope-follower

A fairly straightforward envelope follower and an amp circuit giving up to 20X signal gain. It means you can connect a guitar or microphone to your synth and generate a gate, an envelope and the audio signal at standard synth voltage levels.

The envelope circuit has a 'response' pot which actually greatly increases the gain on the envelope and is useful for very low level signals, there is a trade-off of some distortion on the envelope at high gain settings.
