"Does the job well, works immediately."

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 that let you do more with your pedals.
