Yes, Have Bome MIDI Translator access your nanoKontrol2 port directly. Then pass through any messages (via MIDI thru or translator) to a Bome Virtual Port and then in Gig Performer only enable the Virtual Port. On Windows only one application has access to a given MIDI port at given time.
Controller → MT Pro → Virtual Ports 1-9 (each going to a separate application)
Applications → Virtual Ports → MT Pro → Controller
