Critic Reviews

Expert Sleepers ES-9 review | MusicRadar

musicradar.com

The Expert Sleepers ES-9 is a modular interface that excels in providing extensive audio and CV connectivity, making it a versatile addition for any Eurorack setup. With a total of 16 channels, top-notch 24-bit audio quality, and USB-C convenience, it transforms how musicians integrate modular synths with DAWs like Logic and Ableton.
