Expert Sleepers ES-5 mk3

The Expert Sleepers ES-5 mk3 provides eight clock/gate/MIDI/sync outputs for their ES-3 Lightpipe CV Interface module. Additionally, the ES-5 sports expansion headers that allow for the connection of up to six additional modules (like the ES-4 Gate Expander and ES-8 USB Audio Interface). 

ES-5 mk3 Features

  • 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-5 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.


  • Panel width: 4HP
