mixvibe Cross and the hercules mk4 MIDI mappings

I was watching this tutorial on MIDI mappings for the controllers and the guy is obviously using a mac and in the clip he picks his controller and then clicks this red button and he's using easily but i can't do it on my PC....so check out this clip and see if you know what i mean.
