Here we can see one of the prototype Envelope Follower circuit boards designed recently. The aim of this project is to produce a single Eurorack module with seven separate envelope followers, this module will collectively allow each individual Guitar string to produce an separate Control Voltage (CV). These CV's can then be used to modulate Oscillator tuning, LFO rates or Filter Cut-off Frequencies; turning an almost standard Guitar into an expressive synthesis controller. The circuit was designed with accuracy and broad scope of application in mind, meaning it will also work with Line Level signals if required. Attack time is adjustable as is output gain; Couple this with some band pass filters and some interesting things will ensue...
There are quite a few Eurorack modules in the works at the moment but this one I'm pretty proud of. Updates will follow (pun intended) as things progress...
