ES-8 USB Audio Interface

Expert Sleepers ES-8

The Expert Sleepers ES-8 is essentially a USB 2.0 interface built into a Eurorack module. It features DC coupled ins/outs that can process both CV and audio signals—meaning it is compatible with CV generation software like Silent Way, Reaktor, Max/MSP, zMors, and CV Toolkit. It is also compatible with CV generating iOS apps. 

If all this wasn’t enough, the ES-8 also features ADAT ins/outs, meaning it can connect directly to an audio interface for extra pre-amps or 1/4” outputs. There’s also an expansion header that links the module with the ES-5, which can then be connected to Expert Sleepers’s CV, MIDI, and Gate expanders. 

In addition to its pristine internal clock, the ES-8 can also sync with clock signals sourced from the ADAT signal.
