One knob for which I can't think of a slider equivalent it the 'Alpha
Wheel'. You know, you can go on turning it through a full 360 deg. The
primary use for one from my point of view is in doing a surround pan,
placing a source anywhere in the circle around the listener. I set up
one in the Creamware Pulsar environment, and it worked pretty well - the
bigger the radius of the mouse movement, the more precision of movement
you got (and a wide radius is easier to control than a small one...).
One other aspect of knobs, apart from their familiarity to the user, is
that I think the assumption in most cases is that they are not supposed
to be used frequently or dynamically (my surround example
notwithstanding), but occasionally adjusted, as you would on a 'real'
desk. Sliders really come into their own when you have a row of them,
where the relative position of several is relevant, as it obviously is
for mixer channels. A knob is more visually effective where it is used
for a parameter with a central norm and a +- range.
