I only managed to get the coremidi connection working, but like others cannot get the touchosc bridge to receive midi data. The website is very unintuitive, and livecontrol does not function and so ableton live is rendered useless. I am able to get the Simple template to work, but only using coremidi. My advice to the creator is to address these problems and also create a more intuitive website, as this is not currently the case.
