"Transforms the analog resistance-based controller of your choice into a user-defined and shaped MIDI transmitting device."
      -- Brynjulf from Oslo, Norway


MIDI Expression devices are class compliant USB MIDI pedal interfaces. Pedal sensing technology built into each device automatically loads custom presets when various types of pedals are plugged in, allowing them to support a whole range of pedals with zero fuss. This functionality is enhanced by a preset editor application that gives demanding users all the control they need and exposes powerful features like pedal calibration, adjustable expression curves, and advanced processing modes.

Reasons to use MIDI Expression

  • You need an input that can handle a wide range of different pedals.
  • You want hands-free control of your music rig or DAW.
  • You want to put your collection of pedals to good use.
  • You need a compact and efficient pedal interface for your live performances.
  • You want to give your virtual piano all the pedals found on a regular piano.

If any of the above apply to you, I recommend spending some time checking out some videos and having a look at the manual to see if MIDI Expression is right for you.
