SMK25 MIDI Keyboard Connectivity Fix

My SMK25 MIDI controller refuses to speak to my Windows PC inside Cakewalk, even though the keyboard powers on and appears to be sending data. I’m looking for step-by-step help to isolate and resolve the connectivity issue so the SMK25 is recognised as an active MIDI input in Cakewalk by BandLab...
