As I needed to build an amplifier circuit for the synth project, I decided to breadboard the VCO in order to better design and test out the circuit. After getting the amp working I was curious to try out one of the other modules so I assembled the VFC to see how it worked.

Here is a short video of it in action. Very impressed with the quality of the sound, even though I’m playing through a crappy speaker. The wave form looks perfect. Very impressed indeed:

Can’t wait to get this thing built.
