As discussed previously, I made some notes on how to configure several Expert Sleepers hardware and software modules for Ableton Live. [PDF]
The relevant modules are the ES-4 (out of production -- prematurely, IMHO), the ESX-8GT gate expander, and the ES-3.
This post is a message in a bottle for any lost soul who is trying to make the gear work as it does in the videos. The PDF is a work in process as I continue to pick up new info-scraps on the modular synth forums.
