First: In general I don't understand why the difficulties to fix problem 2
(continuos controls with certain meanings) should prevent us from solving
problem 1 (the enumerations) where Fons already suggested a perfect solution.
Moreover, as you already granted, problem 2 is less severe.
Usually the meaning of certain points is displayed in the port name (as in
the examples you mentioned). I don't know of any plugin where there are
more than 3 defined points, so the string won't be too long for this and
using just a slider control seems fine.

So, will that make it into the next LADSPA spec ?
