Hi there - as it's currently implemented, the Make Controller Kit only communicates via UDP...it doesn't open a socket for TCP communications. TCP is certinaly on the list, but hasn't been implemented yet.
I'm not familiar with LabView, so I'm not sure which other options might be available.
Well, not knowing much about LabView, I'm afraid I can't be too much more specific.
You might check how LabView sends its packets. There might be a bit of work involved to create a properly formed OSC message. Maybe try googling around to see if there's already a LabView OSC implementation out there?
