While generally not liking rotary control emulations, when I do come
across these I will only use ones with a linear action, the others I
find impossible to use effectively.

I would also suggest the enhancements that Rosegarden uses. The first is
the the action is in fact x+y / -x-y, so that either vertical or
horizontal movement works.

The second is that if you double click on the knob it pops up a spin
box that shows the numerical range, has up/down spinners and allows
direct numerical entry.
