State Variable Filter – CMOS version

This SVF is built using a cd4069 CMOS IC and I have to say I was relly blown away by the sound. Super easy build. Found it on Lauri’s Channel on YT.

sadly I had no more space for the Bandpass output *sadsynthnoises*
Don’t forget to ground the inputs and outputs also all ICs like 100nF caps to ground at the power pins 😉
