Pre-outs Eurorack Expander for the WMD performance mixer

An expander module for the WMD performance mixer that outputs channels 1-10 and main pre-fader outs on a separate 6hp breakout module.


Overview

An expander module for the WMD performance mixer that outputs channels 1-10 and main pre-fader outs on a separate 6hp breakout module.

Module output jacks:

  • Mono channels 1-6
  • Stereo channels 7-8
  • PM Channels 9-10 (Optional - disconnected if PM channels is not present)
  • Stereo out (effectively active multing the stereo outs on the Performance Mixer)

Contents

Use cases

Connect pre-fader outs from any PM channel to other modules,

  • e.g. a sound card such as ES-8, ES-9 or external USB mixer to record mixed channels
  • bus channels for bus FX
  • +other creative uses

A note on output phase

Channels 1-8 have inverted phase. This is a constraint of the underlying WMD Performance mixer hardware, and cannot be readily fixed in hardware without making the design much more complex.

The intention is that the phase of these channels should be inverted either in software or by an effect such as the “invert phase” filter available on the Expert Sleepers ES-9.

Channels 9-10 and Main outs (L&R) do not have inverted phase.
