I've made my first knobs with circular response, and was very pleased
with the behave, like Thorsten points out, distance to the center is the
key therefor. jump-to-mouse is a no-go therefor, but that's thru for
any (audio) controller.

However, most users complain about circular response, so we've changed
it to linear behave.
Today, I mostly use the scroll-wheal to change values, . .
