This can be reasonably represented with the port groups extension so any
host can do the reasonable thing.

That said: Some other convention for "audio ports that are actually
controls" might be good, but I've basically been assuming that some more
powerful extension for 'CV' ports and such will come along anyway... and
audio/control rate polymorphism...  That dichotomy from LADSPA (and
consequent mess of different versions of the same plugins) really sucks.
It must die. :)
