Expert Sleepers

Expert Sleepers is a British maker of Eurorack synthesiser modules and music software. Its range includes audio interfaces, MIDI and control-voltage interfaces, multifunction processors, oscillators and amplifiers, serving musicians who work with modular synthesis and computer-based production.

The brand is known for connecting modular systems with computers and other electronic instruments. The ES-9 provides USB audio interfacing in Eurorack format, while the FH-2 handles MIDI-to-control-voltage conversion. The disting family offers multiple processing and synthesis functions within individual modules. Other products include the Lorelei oscillator, Persephone VCA and USAMO, which generates MIDI output from an audio signal.

Expert Sleepers occupies a specialist position in the electronic-instrument market, with both small expansion modules and more substantial interfaces and processors. MyGear currently lists 26 products in stock at partner retailers, with listed prices ranging from £43 to £10,000. This catalogue-wide range covers different product types rather than a single comparable class of instrument.
