I experienced it twice in Live 10. I'm not sure how it happens but suddenly, the Gain goes down and the knob is rotating on it's own like it was having a spasm attack. Odd.
I simply added an instance of this before the L2 limiter on one project and on another, I actually put it in front of KClip.
If anyone else has experience something like this, I would interested to know that I'm not going crazy.
