voltage controlled oscillator
this is the Erikasynths Build of the Moritz Klein ‘shapes’ VCOI built it and it tracks okay I’d say. I used superglue on the transistors and 4 layers of shrinkwrap around them. I’m happy with it so far. Link to original project page: Here
This VCO has two oscillators. They can be tunes seperately. The theid knob is for changing the waveform (noise, saw, tri, sine, square) It takes a 1v/Oct signal for the pitch and has an octave switch to set it one octave higher or lower.

This Mozzi based Arduino VCO sounds really great. Link to the original project page: Here Hagiwo’s code: Important to note is that you’ll need the MOZZI Arduino Lib to get this to run. #include <MozziGuts.h>#include <Oscil.h>#include <tables/cos2048_int8.h> // table for Oscils to play#include <mozzi_fixmath.h>#define CONTROL_RATE 256 // Hz, powers of 2 are most reliableOscil<COS2048_NUM_CELLS, AUDIO_RATE> […]
I did a bit of tinkering on this one but sadly didn’t document it too well. For now this was my starting point and I’m sure it is not far away from my final build. The Mod input makes it a pretty freaky FM kinda VCO. Have fun with it. Link to CuSis Youtube Video […]
This AS3340 VCO build has everything you can possibly need from a classic analog VCO (imho). I used a verified stripboard layout and the electrosmith submodule: Link
