You can already use TouchOSC : http://lab.millumin.com/tutorials/?name=touchosc
or Liine Lemur

I have actually been looking into the SDK and seeing if i can make a more full featured control than what is currently in the touchosc files, i will report here if i find any details of the osc impimentation that could use minor addition. if there is contextual data in the osc ping about the names of the parameters and values of isf files i think that is all i need.
i also had a very interesting idea about having the new ios11 ARkit and camera function as a rapid mapping adjustment dream tool: walk around the scene and tweak mapping details from spatially tracked nodes on the ipad.
it's already possible with touchosc
would prefer to have first a whole control threw OSC, would able the possibilities to make our own ipad Controller. But ++ for that idea.
