I have a UR22mkII and a DrumPad (KAT multipad ktmp1) with a midi output 5pin. When I connect this to the Steinberg with a 5-pin cable, nothing happens in the DAW (LoopyPro). Have I connected it correctly?

I am not familiar with LoopyPro but the connection using a standard MIDI cable is pretty straight-forward. It’s either a setting in the Drum Pad, the OS or in the DAW that prevents receiving MIDI data.
