Simple VCO – First prototype

Simple VCO, ,

Following the Simple LFO module, here comes the Simple VCO.
It’s a very stripped down version of the Formant VCO, modified and adapted to the Eurorack format.
This circuit is also present in the VCO section of the DM77 Drum Module.


The Simple VCO is 1V/Oct capable. In order to reduce the number of parts, only one waveform output is available.
The result is a super simple module, easy to build, to understand and maintain.
