"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...

Features:

- 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

Specifications:

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