Put the device as a midi effect before your instrument on a midi track.
Just monitor the midi notes in and check the midi notes out conversion. The midi channel is only indicated in a brief monitoring purpose (midi routing inside Ableton can be tricky).
Velocity is by-passed and stays identical from in to out.
Quick set the note received (send by your controler) you want to be converted and transmitted to the instrument. Eight converters are available, related to the typical hardware design of pads.
