Trying to use a Nord Drum 3p to output MIDI to the Keystep then usb to comp

[Vaulsc]

I've got a Nord Drum 3p using a MIDI cable to output signal to the Keystep, which then plugs into my computer via USB. I can use the keystep as a MIDI controller, but can't get the Nord Drum 3p to control MIDI via the keystep.

Don't have a MIDI interface at the moment to put the Nord Drum 3p directly to the computer.

Any idea if this is possible or if there are settings/config needed to get this up and running?
