Expert Sleepers ES-9

The Expert Sleepers ES-9 is a full-fledged audio interface in Eurorack format, making it easier than ever to connect your computer to your modular synthesizer. Best of all, some niceties unique to the ES-9 make it capable of even replacing your traditional audio interface—so gigging with the ES-9 is an ideal way to lighten your load and decrease the headache of setting up an interface for live performances.

Like its older siblings, the ES-9 is a DC-coupled interface ideal for sending audio and CV information between a modular synthesizer and a computer. Simply plug it in via USB and use it like any other interface; it's class-compliant as well, so no special drivers are needed to get it up and running. It offers a total of fourteen DC-coupled, Eurorack level inputs, and eight DC-coupled outputs—meaning that it could easily become the hub for multitracking your synth, for routing CVs, and much more.

The ES-9 also provides special facilities absent from prior members of the Expert Sleepers family. Most important among these are a pair of line-level main TRS outputs and a headphone output with dedicated volume control, making it easier than ever to create a unified live setup with your modular synth. With all of these new features, ES-9 is sure to become a staple of countless modular synth setups.
