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.

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.)
