Module number 3 in the Erica Synths EDI DIY range is the EG Envelope Generator with optimised controls and looping. Comes with a complete build guide and will teach you how an envelope circuit is designed.
EDU DIY EG
While we’re waiting for the arrival of the EDU DIY case Erica Synths has decided to let us get on with the next module; the Envelope Generator. Envelopes are a vital part of any modular system as they give us a way to change voltage over time. They can be used to control the volume through a VCA or how a filter cutoff moves with every note and in fact, the EDU system is designed to run with two envelopes so you should probably buy two EGs.
As with the other modules in the range they come with detailed videos and a manual that opens up the concepts and dives into the circuit design. First, you learn a bit about the concepts and then you start to put those ideas into practice on a breadboard before finally soldering the kit together into a fully functional (hopefully) module.
There are 9 modules in the range that Erica is releasing every 4-6 weeks. So far we’ve had the VCO and VCA. I’ve been live-streaming my builds of them in the hope that we can tackle the sometimes complex and challenging subject matter together. It’s been completely brilliant and I feel I’ve learned so much more than if I was just building the kit.
Designed by Erica Synths and Moritz Klein the whole system will take you through a course in Eurorack module design and understanding synthesis.
The EDU DIY EG kit is available now for €55.
