Expert Sleepers ES-10 – ADAT Audio & CV Interface

The Expert Sleepers ES-10 is a streamlined yet powerful ADAT-based audio and CV interface designed for Eurorack systems. Building on the legacy of the ES-3, ES-6, and ES-7, the ES-10 combines the functionality of all three into a compact 12HP module with modern upgrades.

It features eight DC-coupled inputs and outputs, allowing you to send both CV and audio between your modular system and your computer via ADAT. With selectable modular or line-level input modes per channel, it offers flexibility that makes it equally useful in live and studio setups. Whether you’re routing envelopes, LFOs, pitch CV, audio, or automation from your DAW — the ES-10 handles it with precision.

Inside, the ES-10 uses high-end AKM "Velvet Sound" converters, delivering improved audio fidelity compared to earlier models. And while it doesn’t use USB, the reliance on ADAT optical makes it a perfect fit for anyone with an audio interface that includes ADAT I/O — no drivers, no fuss, just plug in and go.

If you need to expand further, the ES-5 header opens up the system to additional gate, CV, and MIDI expander modules, continuing Expert Sleepers’ tradition of modular flexibility. It’s an ideal solution for anyone looking to seamlessly integrate analog and digital environments without sacrificing space or sound quality.
