My use case it as a general purpose expression pedal to use alongside my Novation midi controller for various soft instruments (organ, synth and others).Physically the device seems robust enough, though looking more closely there is a plastic coupling, which I assume physically translates the rocker action to a linear potentiometer

Expression is quite a broadly supported midi dimension so it tends to work as a volume adjustment in most soft instruments without configuration

Maybe, but this is the 2nd M-Audio product to fail me in the past month
