The Expert Sleepers ES-8 is a USB 2.0 class-compliant audio interface in a Eurorack module, with DC-coupled inputs and outputs that can be used for both CVs and audio. As such it is directly compatible with all popular computer-based CV generation software (e.g. Silent Way, Max/MSP, Reaktor, CV Toolkit, zMors, etc.) as well as audio and CV processing iOS apps.
The ES-8 also has ADAT inputs & outputs. This could be used for example to expand the output count via an Expert Sleepers ES-3 and/or ES-6, or to connect a traditional audio interface to add, say, mic preamps or 1/4″ line outputs.
An expansion header allows connection of an Expert Sleepers ES-5, to which in turn you can connect our gate, CV and MIDI expanders.
The ES-8 has a high quality internal clock, and it can optionally sync to the clock from the input ADAT signal.
Basically this thing is like the Babelfish from Hitchhikers Guide and will let you communicate with ANYTHING. Madness.
