ES-5 (ES-3 Expander)

Expert Sleepers

  • $ 15000

The ES-5 is an expansion module for the Expert Sleepers ES-3 Lightpipe/CV Interface.

It piggybacks on one of the ES-3's stereo channels to provide eight gate/clock/sync/MIDI outputs on the ES-5 itself, plus further expansion headers to connect up to six expansion modules e.g. the ES-4 Gate Expander.


  • Panel width: 4HP
  • Module depth: 49mm
  • Digital input: connection from ES-3 module
  • Analogue outputs: 8x 3.5mm jacks, DC-coupled
  • Output voltages: 0V/5V
  • Indicators: LED per channel
  • Expansion
  • 6 headers for connecting expansion modules e.g. the ES-4 Gate Expander
  • Current draw: TBC

    The front panel is drilled for both Doepfer and Analogue Systems mounting holes (using a 'slot' rather than a single round hole). The power connector is a Doepfer standard 16 way IDC, with -12V furthest from the top of the board.

    Note that connection to the ES-3 is by a simple plug-in cable for the ES-3 mk2 only. The original ES-3 requires some soldering to add the required connections.

    For more detail, please see the user manual.

    Software Requirements:
    Unlike the ES-3 itself, the ES-5 requires particular software in order to generate meaningful output signals. Currently, the only such software is the 'ES-4 Controller' plug-in, part of Expert Sleepers Silent Way.

    Silent Way is available in AudioUnit and VST formats for Mac OS X and Windows. Use of Silent Way therefore requires a compatible host application (DAW). For Pro Tools users, Silent Way is known to work with the FXpansion VST-RTAS wrapper.

    A Silent Way licence is not included with the ES-5 - however, the ES-5 Controller plug-in functions in a licence-free mode, so ES-5 users are not forced to buy Silent Way. Such users can than evaluate the rest of the Silent Way suite in demo mode.
