The VCO is an analog voltage controlled oscillator with a wide frequency range and 8 trackable octaves. It uses the Curtis CEM3340 reissue chip, which is famous for its outstanding sound quality. This kit is already partially made; the logic board (included) is pre-built, so the only board that needs to be soldered together is the control board.

DIY VCO kits and PCB's for your modular synthesizer in Eurorack and other formats!

The mki x es.EDU VCO is the first educational DIY kit in this series. It is an analog sawtooth-core oscillator with a reasonably accurate volt/octave tracking, made from just a handful of basic components. It features sawtooth and pulse outputs as well as 1V/oct, FM, and PWM inputs.

Build it from a kit! This Voltage-Controlled Oscillator is based on the Curtis CEM3340 IC. The boards are available fully-assembled or in kit format. Can be used as a standalone board, put in an enclosure, or mounted behind a modular synthesizer panel (a Eurorack-format panel is available from us, or create your own).

Build North Coast's complex VCO kit for a journey to the East or the West, or bring it home as a stable foundation for any Eurorack. The module contains two triangle-core VCOs, each with four waveforms and Eurorack-standard V/octave pitch CV.
