I´ve created a 3D visualized ball and want to rotate it faster, when the beat hits harder.

I dont know how you can stack up a value, in this case my x,y,z rotation.

I´m trying with time* and so on right now, but i just can get a steady movement.

My audio output can influence the rotation further, but this gets reset, when the output value goes down.


Sorry for my english, i hope you can understand my issue

Hard to say for sure from your description, but it sounds like you might need an integrator. It's not trivial to set up, but this might help:

Trapcode Soundkeys has an accumulating option for the output. It is essentially the same result as Dan's frame-by-frame method, if you convert the expression output to keyframes afterwards. I would recommend converting the expression to keyframes, otherwise you'll have to calculate the output every time you try to render the video. What I do, to keep the editable expression, is make a copy of the layer and hide it, then convert the copy, so that I can go back to the expressions if need be.
