Erica Synths & Moritz Klein have introduced the mki x es.EDU VCA, a simple, but efficient dual VCA for your Eurorack system.
The EDU DIY VCA has DC-coupled inputs, so you can use the VCA both for audio and CV signals. Inputs of the second VCA are normalled to the first one, which lets you split the audio signal to both VCAs, or control both VCAs with a single CV.
A 60-page build manual explains the electronics behind the module and provides step-by-step build instructions.
The mki x es.EDU VCA is one in a series of 9 DIY kits that are designed to let you build a fully-featured modular monosynth: a sequencer, a VCO, a wavefolder, a noise/S&H module, a mixer, a VCF, an Envelope generator, a dual VCA, and an output stereo mixer with a headphone amplifier.
Pricing and Availability
The EDU DIY VCA is available to pre-order for €55.00.
