I'm not sure that all of this belongs in LADSPA (the Simple Plugin
Architecture). DSSI has support for presets, MIDI in, GUIs and some
support for polyphony (you can run several plugin instances as a
polyphony group with a single call to run_multiple() which lets you do
common calculations once).

About referencing: isn't the port index the common way to identify
LADSPA ports?
