YUY0 - CMOS based Raw Modular analog sound machine

🎛️ Here's another jam with my full CMOS DIY modular synth I'm planning to keep developing it and hopefully put it up for sale soon. I'd love to know if any...

Randomly stumbled on this today - a proto board CMOS synth demo. Sounds pretty good for a bunch of CD4xxx ICs !
