Aaaaaarrrrrggghhhh - knobs. One of my pet peeves.
I actually wrote a knob GUI element for Pd, which normally only has
sliders. I see one good application for knobs: Visualizing things
that must not take up much screen space.
They also have the advantage of a more obvious centre position than a
slider, I believe they can be significantly quicker to read, although
not to edit, and they can be placed in meaningful groups more easily.
I think they're a much better GUI element than people give them
credit for.
Agreed, or can be. The exat implementation can make a great deal of
difference to the usability. One of the nice features is that you can set
controls more accuratly that sliders without using vast ammounts of screen
realestate.
The problem is knowing when to use them. Rosegarden
uses knobs for
all LADSPA port controls, and the results are not very satisfactory.
Jack-rack uses sliders for all LADSPA port controls, and IMHO the
results there are not satisfactory either, although they are
generally better. The ideal would be a mixture but I don't think the
host can reliably tell which should be which. I imagine the real
value of a custom GUI is in contextual and organisational details
like that. (Although I do think flashy graphics can be nice too.)
My guess is that, often, knobs are better for LOG scaled things and
sliders btter for linear. Just a rule of thumb though.
