[sdiy] Hex Inverter VCF Idea

[adam at hoodmusic.net]

I found this idea for a 4-pole VCF with VC resonance and a VCA on the
output in one of my old note books. It uses 2 hex inverters, one for the
4 stages of the VCF and the VCAs for the resonance loop and output VCA,
and the other hex inverter is used as six FETs to very the resistance of
of each stage of the VCF and the VCAs. It is just a rough drawing, and
is far from a working filter. I wanted to know if it had any chance of
ever working before I started trying stuff ut in the real world.
