Rotation to music expression?
Hey so i’m looking for an expression to make something rotate based on bass and treble null objects. Just to be clear, i’m trying to rotate 1 object based on my bass slider, and a different object based on the treble slider (so 2 objects total, only one expression needed i’m pretty sure, just change the “bass” variables to “treble” if i’m not mistaken)
I’m trying to make it rotate in one direction and then speed up and slow down based on how hard the bass or treble kicks in.
anyone got any ideas?

Some variation of the first expression in this section should do what you’re looking for:

It’s designed for time remapping, but it should work fine for rotation.
You’ll probably want to increase the value of mult (10 maybe?), and you may want to keyframe a steady base rotation value so that the expression adds the surges to that (although it would be pretty easy to build that into the expression as well).
