Regarding knob UX, I just went through my VST plug-in collection to compare my implementation against theirs and found that each one is tuned a little bit differently and has somewhat different ideas. However there is a strong convention to use vertical axis movement only, while I am using both axes - so I will change that in the future to follow the convention, and also do some further tuning to make sure it feels OK on pointer configurations that aren't my laptop's touchpad.
There are a minority of developers that do a "rotate around center" knob as TheMeorch suggests, but it's actually much harder to work with as it makes the response to your movements less consistent.
