It is the other way around for SuperCollider.
LADSPA plug ins are not capable of being SC plug ins because they may
allocate memory and do not guarantee bounded start up time. They also do not
generate sample accurate end time stamps which SC requires.
SC unit generators could probably be wrapped to work in LADSPA, but it would
probably be more useful to wrap SC patches rather than SC unit generators.
So LADSPA isn't a common denominator. I don't think there can be such a
thing.
