The Expert Sleepers ES-2 CV/Audio Interface is a Eurorack module designed for use with software such as Expert Sleepers Silent Way. It takes as inputs CVs from your analogue synths/effects on 3.5mm jacks, and outputs audio signals on 1/4″ jacks which you connect to your computer audio interface. You then use the Silent Way CV Input plug-in to interpret the audio signal and output CVs in your DAW for recording, processing etc.

This module is avalailable in 2mm orange painted aluminium.
