Hello,
Nothing wrong here.
When you say the knob rotate, then do you mean it jump to max or that you can set it to any position but still have full output? If it's the first, then you might use a controller set to a relative mode, and that Mini V does'nt match that mode for the cutoff.
Also are you sure the hardware control knob is'nt broken? I assume you don't use the mouse to control the Cutoff.
if you afterall should have a application issue, then did you try to reinstall Mini V3?
