The list of default types is in the ontology file (ladspa.rdfs), but you can
just declare new ones in a file ships with the plugins, as in:

  <rdfs:Class rdf:about="&ladspa;SurroundPlugin" ladspa:hasLabel="Surround">
    <rdfs:subClassOf rdf:resource="&ladspa;Plugin" />
  </rdfs:Class>

eg. in swh-aux.rdf I declare SpectralPlugin and NotchPlugin, which I
needed, but aren't in ladspa.rdfs.

The nearest to Synthesiser is Generator, which is far from a good name.
The list of types was just hacked out by yours truely one afternoon, and
its both overspecified in some ways, and underspecified in others. It
could do with an overhaul.
