from aleksei:
"This is hi-quality Quad VCA-Mixer. I used maybe best available VCA chips THAT2180 and OPA2604 in audio chain, TL074 for CV.
4 identical VCAs and mixer to mix channels in pairs and all together, each channel has separate out too.
VCAs feed both AC or DC sinnals.
Responce curve is in the middle between exponential and linear. Normalized to 5V and attenuated by LEVEL pots, CV INs control VCAs gain."
