Collude - Envelope Follower PCB | NonLinear Circuits

This module is a fairly straightforward envelope generator (based on the Electronotes design) and gain stage.

The gain stage can be set to increase a signal’s amplitude from 2X up to 20X. This allows signals from guitars or microphones to be ramped up to levels suitable for processing in a modular synth.  The envelope follower has been designed to have a somewhat ridiculous amount of gain so that very low level signals can be used to form much larger envelopes than they should, there is a trade-off when using this function as the envelope is quite jittery and dirty (over-sensitive), this is not necessarily a bad thing. For normal use, say with a guitar, the respond pot would be kept quite low.The gate pot controls the comparator threshold level; use this to get gates as wide or narrow as you wish in response to the incoming signals.
