HINT_MOMENTARY, yes, I've been asking for it for months. They cannot be
aproximated by toggles (think of tap tempo or sync reset controls), and
are at least as important as enumerations, which can in most cases can be
aproximated by notes in the port label. I still dont think that listing
some hardcoded presets in an integer control port is a good way to have
presets. It screws up automation for one thing.

Which allready uses lrdf (at least the devel version does). And anyway -
enumerations are not a good way to solve that problem.

Could, but its far from neccesary.

Its not that LADSPA is missing combo slections, its just that thier not
labelled - users have to look in the docs. Momentary switches are just not
there at all.

All of the features missing from LADSPA seem neccesary to someone - but if
we add them all in the nwe will have a crappy and still incomplete plugin
format, just like VST or DirectX.
