2164 Quad Exponential VCA

Maker	DIY Synth Manila
Type	Quad exponential VCA on the AS2164 with normalled signal and CV chains and a mix output
Mounting	Through-hole
Width	—
License	Proprietary (Licence marked "none yet" on this repo)
Difficulty	🌡️ Medium through-hole

Signal input 1 cascades to any unpatched input and CV 1 cascades likewise, so one CV can open all four channels. A jumper switches output 4 between VCA 4 and the mix. STL for a 3D printed panel is included.
