Solved-How to control the speed of a rotation

Hi, thank for the reply,

I mapped the value from 0-127 to 0-1.
I use WhichRotation because I made another rotation that is trigged by a drum.

I don't really care about the Deg/second, I just need to accelerate the rotation or decelerate it, then It's a visual performance, so I'll ajust the final speed.
