so, does each midi note have its own parameter? or how else are you
encoding the data? obviously things like pitch wheel need to be passed

Well i was working on this type of host program, but for the plugin spec
im now using in amsynth. Obviously if LADSPA is really feasible for this
kind of thing, i'd want to get that working..
