This project is a dual voltage controlled amplifier. It has one signal input with level adjustment, two CV inputs (one with level control), and one control for initial level. The VCA is based on the ASM-1 VCA.
Unfortunately there are no building instructions for this module, but at least you'll find the schematic, some photos, and some comments.

Yet under construction.

That's it! Have fun and attenuate!
