AH and overbridge questions

I just got an analog heat, so far I am loving it as a hardware box.
On the other hand I seem to be getting nowhere with the overbridge or the audio streaming.
I mostly want to be able to stream the cue outs of my octatrack to ableton live and send pc messages from live to change the patches in the heat.
So far so bad.
I have a 13 inch MacBook Pro, live 9 and a motu 828 audio interface.
Any help is greatly appreciated.
