Tapage or is that just a mistake in the error it posts?
it's an error of the error.
A couple of lines above that error line in here it says:
noiseThreshold noise threshold, float: 0-0.0625, with 0.0625 being the highest noise thresh
Could you go back to the Trill/bar-visual
example and add this line
touchSensor.setNoiseThreshold(0.04);
before touchSensor.printDetails();
and then run and look at the GUI again? is the touch still there?
There is another parameter that could be useful "minimumTouchSize". Unfortunately this is not (yet) exposed by the Sc ugens, but it's mostly equivalent to filtering out on the Sc side all the touches that are very small (by applying a threshold to the touch size value).
Incidentally, the reason why I am referring you back to the C++ API for testing first is because that's the one we have tested, and so I wouldn't want that you'd be seeing errors in Sc that are due to the Sc interface. Let's get to the point where it works fine in C++ and then consider how to best have that done in Sc.
