We're talking about the impact one ? Cause indeed they say the impact one has a force data, but the contact one should only be contact or no contact i guess... I fear i'm never going to find out how to fix that -_-That doesn't sound right to me. I just hooked up a trivial experiment and, if the Slow Power Up setting is 0.0, the a free-standing keyframe (e.g. not on a timeline) instantly applies. The only way I can make that not the case is if I don't apply a full signal to the power socket. If I send a value less than 1 into the power socket, it interpolates, but if it's 1 or more, it is instant. Is it possible that the output you're getting from the impact sensor is not 0 or 1? It looks like the first value in the fat wire that comes out of the impact sensor is the 'impact' described as the force of collision. It seems to be binary for the 'touching' impact, but presumably not the others.
Anyway i just worked 6 hours on creating a music for the world 2. Dreams will kill your life.
