Analog Lab without hooking up the Keylab MKII

I’m trying to use Analog Lab in my DAW (CAKEWALK) without taking the MKII. I have my guitar synth(GR-20) playing into MIDI inputs. I can select the inputs from m track, other synths work fine. Under the inputs listed in AL there are all Arturia controllers, factory, laboratory, generic 9 knows and generic 9 knobs and 9 faders. Isn’t there a way to control AL with generic MIDI? Thanks.
