Its firming up. Any LADSPA plugin with an equal number of inputs and
outputs should now work. I need to do more to get unusual plugins to work
and to optimise for common cases.

Currently ladspa control ports are mapped to GObject args so you can
introspect on what is available.

At the moment yes. I am also working on a seperate DynamicParams api which
will provide more multimedia-specific parameter behaviour than GObject args
can provide. In short it will provide the following:
- pluggable param types (probably based on GType)
- pluggable interpolators to create time-aware envelopes
- pluggable units-of-measurement (and unit converters)
- parameter update frequencies which can be non-constant and completely
independant of buffer frequency (this is optional and possibly not desired
for real-time)
