Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Expert Sleepers ES-8 USB Audio Interface Eurorack Synth Module.

Features and functionality

  • The ES-8 works seamlessly with VCV Rack and can function as a virtual mixer, offering flexibility in sound manipulation.

    Source
  • The ES-8 must be chosen as the audio interface in Bitwig to send/receive CV signals, limiting the use of other interfaces without additional setup.

    Source
  • The ES-8 offers 8 outputs and 4 inputs, which can be limiting for those needing more inputs for extensive multitrack recording setups.

    Source

Software and compatibility

  • Compatible with Python's PYO library, allowing specification of DC voltage and oscillators from the command line.

    Source
  • The ES-8 can be used as an expander with interfaces that have both ADAT in and out ports, essential for signal routing.

    Source
  • On Mac OS, users can create an aggregate device using Audio MIDI Setup to use multiple interfaces, a feature not natively available on Windows.

    Source
  • The ES-9 uses TOSlink connectors for SPDIF instead of ADAT, which may limit compatibility in setups expecting ADAT support.

    Source

Setup and maintenance

  • For non-Eurorack instruments like guitars, using a level shifter is recommended to manage input levels effectively.

    Source
  • The OPTX's high-pass filter on inputs enhances sound quality for audio but may distort slow-moving voltages, affecting CV use for pitch.

    Source

Use cases and applications

  • Ideal for users wanting to integrate modular synths with Ableton without requiring additional interfaces for MIDI to CV conversion.

    Source
  • When paired with interfaces like the UAD Apollo Twin, the ES-8's ADAT connection is crucial for maintaining audio output through the main interface.

    Source
  • For integrating guitar or vocal inputs at modular level via Babyface, the ES-8 can effectively handle this task when paired with the right setup.

    Source

Comparisons

  • Unlike the ES-9, the ES-8 is more suitable for those prioritizing space, as it consumes less HP in a Eurorack setup.

    Source
  • The Boredbrain OPTX, in contrast to the ES-8, provides 8 inputs and outputs over ADAT, making it suitable for tracking multiple stereo or mono voices.

    Source

User experience

  • Some owners plan to upgrade from ES-8 to OPTX due to its compact 8HP size and better input/output capabilities for recording purposes.

    Source

Build quality

  • Owners report noise issues on the OPTX's 8th input and lack of DC coupling on inputs, affecting its use for precise CV applications.

Expert Sleepers' ES-8 bridges the gap between modular synths and computer-based DAWs with its seamless USB interface, offering flexibility for audio, CV, and timing signal integration. While its versatility is a boon for those deep into modular setups, the lack of initial PC support and reliance on ADAT interfaces might deter some users. The ES-8 is ideal for those wanting to incorporate modulation and sequencing software into their modular synths, potentially saving costs on additional hardware. However, the setup can be complex, demanding a learning curve that might not suit everyone. Overall, a niche but powerful tool for dedicated modular enthusiasts.

Expert Sleepers ES-8 review | MusicRadar

musicradar.com

The Expert Sleepers ES-8 is a niche powerhouse for modular synth enthusiasts using OSX, offering seamless integration with DAWs through its class-compliant USB connection. Its standout feature is the impressive CV range of ±10V, making it a robust choice for modular setups. However, its Mac and iOS exclusivity limits its audience, and the lack of clear labeling on inputs and outputs may confuse users. Additionally, the sparse online manual doesn't aid in easing the learning curve. While it's not the most versatile for non-modular tasks, for those deep into modular synthesis, it's a compelling offering with room for expansion.
