Tested and Works Perfectly

-- Assembled Eurorack Module --

The MST Expressor allows you to use expression pedals with your modular, taking a “hands-off” approach to expand your control and creativity. It has two identical powered expression pedal processing units in one handy module, allowing you to do things such as:

  • Control volume with your foot
  • Attenuate CV or audio if no expression pedal is plugged in
  • Add positive or negative voltage with the flick of an ankle:
  • Sweep a filter cutoff
  • Transpose CV
  • Pitch bend
  • Direct audio volume control
  • Attenuate and expand external CV
  • LFO rate adjustment
  • Modulation amount control
And more…

  • Processes audio and DC signals
  • Two discreet expression pedal input channels (1/4″ TRS jacks)
  • External signal (audio or CV) input per channel
  • Precise output adjustment: attenuator/scale control per channel
  • 3-position switch select of +5V, -5V or 0V (mute) per channel
  • External input bypasses the switch voltage (the switch voltage and external input are not active at the same time, i.e. the voltage will not offset your input signal.)
  • Red/green LED per channel (red = positive voltage, green = negative voltage)
  • Compatible with passive TRS 1/4″ expression pedals, such as the M-Audio EX-P

  • Current draw: 28mA on +12V; 28mA on -12V
  • Width: 8HP
  • Module depth: 24mm
