I use audio software a lot, and it is amazing how something which seems quite simple in concept, such as a circular volume button, can be so differently implemented via UX.

Every time I see a knob style button on any of my audio plugins UI, I have to think:

* Will the point at which I touch/click on the knob set the knob value to that position, or will it simply be the starting anchor at which I start moving the knob?

* Does this knob work by sliding up/down or in a circular fashion? Or accept both ways?

* How far away, or close to the centre, is the active 'hot spot' that allow me to control this knob?

* Does the knob dynamically display the value as I spin it? If so, where does it show that value and am I inadvertently blocking the display with my finger/cursor?

* Does the knob have the concept of velocity, whereby I can quickly spin it to the approximate value I want, then make tiny incremental adjustments to get the sound 'just right'?

All these tend to break the "don't think, just do" concept of a skeuomorphic interface.
