VAMP is not a realtime plugin API. Its designed for things that need
to do at least 1 pass over the data before deciding what to do.

DSSI was just a stop-gap measure introduced because LADSPA had no way
to support MIDI (and thus you cannot write a LADSPA MIDI-driven
LV2 represents some kind of version of the community's best-effort
attempt to define a better plugin API. It is hard to explain why LV2
is so superior because its rooted in a feature that actually makes it
quite annoying for anyone who isn't instantly convinced that endless
extensibility is the right goal. But it allows for more or less
anything, assuming that both parties (the plugin and the host) can
agree on it.
