It is moving, but so minutely I had to attach a debugger to confirm 
For pitch I think the problem here is that when it was thrown into Novelty we didn’t pause to think that the two dimensions are radically different scales, so the pitch output completely swamps the confidence in the similarity calculation.
In that oboe example, the jumps in confidence are pretty important as marking the transition between those otherwise quite stable multi-phonics. When I rescale the pitch channel internally, it behaves much (much) better. I’ll push that change in due course.
There’s a constant offset to the novelty output as well, which isn’t making me happy.
