did you include an extra dot for position reference in this ? would you 
mind posting your knob ?

and yes: this is actually a very nice and beautiful circle rendering.

but i also share alex' concern that it might be too "heavy" on PD's 
memory or the GUI if several of these knobs are present in a patch.

can somebody give a brief prediction whether this is a practicable 
approach in a patch with let's say 50 knobs like this ?

best
