Mint

  • Expert Sleepers ES-8 Eurorack USB audio interface.
  • Not a normal audio interface. This lives in the rack. Modular talks straight to computer. Computer talks straight to modular.
  • 12-in / 16-out total interface architecture. Big routing brain. Not tiny MIDI-CV drip-feed.
  • 4 analog inputs. DC-coupled. Take modular audio or CV back into the DAW.
  • 8 analog outputs. DC-coupled. Send CV, gates, clocks, LFOs, envelopes, pitch, modulation, or audio into the rack.
  • Approx. ±10V analog range. Built for modular voltage. Not weak line-level “maybe it works” control.
  • 24-bit conversion. Clean enough for audio. Precise enough for control. One box handles both.
  • 44.1 / 48 / 88.2 / 96kHz support. Standard studio rates, still modular-focused.
  • USB 2.0 class-compliant. macOS and iOS run without drivers. Windows uses Expert Sleepers driver.
  • ADAT input + ADAT output. Expand the system. Add more I/O. Connect to bigger studio rigs. Keep the module useful beyond one small rack.
  • Standalone ADAT mode. No USB needed. ADAT can drive the ES-8 outputs; ES-8 analog inputs can feed ADAT out.
  • Internal clock + ADAT clock sync. Runs alone or locks to the digital system.
  • 8HP / 50mm depth. Heavy routing power in tiny rack space.
  • Front-panel 3.5mm TS modular I/O. No dumb adapter mess. No desktop-interface cable jungle.
  • Best for hybrid modular rigs. Bitwig CV Tools, Silent Way, Max/MSP, Reaktor, VCV-style routing, DAW modulation, modular recording, feedback patches, sample-tight control.
  • This replaces workaround stacks. Instead of MIDI-CV box + audio interface + attenuator pile + clock patch mess, ES-8 gives direct CV/audio I/O in one Eurorack module.
  • Where typical interfaces stop at audio, this moves voltage. Slow CV, fast CV, audio-rate modulation, clocks, gates, and audio all share the same bridge.
  • Where typical MIDI-CV boxes quantize the whole idea down to notes and clocks, ES-8 opens the whole DAW as modulation hardware.
  • Why it hits different: most interfaces are studio tools forced near modular. ES-8 is modular infrastructure first — computer control, CV, audio, and ADAT expansion built into the rack.
