Tom, I've never written a LADSPA plugin myself, so beware!
Would it be possible to move everything from tap_reverb_presets.h to rdf
presets?
It seems you'd have to pass all your filter data through ports.
But doing so one could create new filter presets without a recompile.
Does that make sense?
Control ports communicate single values only.
Could audio ports be used to transfer the filter data?
Hmmm, my guts tell me this is not 'LADSPA-ish'.
