Little Boxes Part 10: Filter (VCF)

My latest little box is a voltage controlled filter (VCF). I adopted and adapted a circuit I found on the electro-music forum (). My version has cutoff and resonance but I ditched the cv control. It runs from a 9 volt battery and lives in it's own little box. In the video I give you my (slightly) modified circuit diagram and the strip board layout I used. I also demonstrate some of the sounds you can create using the filter with other little boxes and my Project XII diy modular analogue synth.
