Artist Control knobs leave much to be desired

Is it just my Artist Control that has unsatisfactory knobs? As in, they are inconsistent and inaccurate when you are tweaking values? I.e., sometimes you turn a knob a small distance and it moves the value a certain amount. And then 2 seconds later, that same distance moves the value a much different amount. Or sometimes you move it a lot and the value barely moves at all. And this keeps changing. It makes them basically unusable.



Plus there are too many buttons to push simply to start using an eq or whatever you're going for... I need something better. Anyone else in this boat? I may have to get a Raven MTi or an S3 if they ever make one for PT (not venue version).
