This is one of the most built filters and one of my most hated builds ever. I once bought waay too cheap 13700s on AliExpress and tried to build several VCAs and VCFs with them (FIVE!!!} and NONE of them WORKED. Then I gave up on OTAs. Months later I thought I’ll give it another […]
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.
I always wanted a couple of filter designs in my modular and this one takes up near to no space and works fine imo. Original project page: Here
I can tell you this VCF is one dirrty VCF. It works but you can’t even compare it to any MS-20 build. But it has a ton if resonance. This is the original post: Here
Like the others here’s the link to the electrosmith submodule page: Here The VCF has a cutoff and a resonance pot as well as cutoff and resonance CV jacks and the signals can be attenuated. Two signal inputs and one output make it a really versatile lowpass filter imo.
