Uhm, my messages have been exceptionally sloppy recently. Maybe I
should spend a few code-free days. ;) Anyway, I meant to write 'common
denominator approach'. As you said, finding a real c-d is impossible.
SuperCollider is a good example of how apps require different things
from the effect/ug interface. To resolve this problem, we (a) design
a plugin API with a fat interface (tries to fulfill all requirements),
(b) write multiple specialized APIs, or (c) a compromise API (=LADSPA).
These are all valid approaches, but we can't pursue them all at the
same time.
