I don't like having something this complicated in an extension that is
going to be required if you just want to write a simple synth with a
MIDI input. Is there really any need for adding and removing mappings
dynamically?
Definitely agreed.
Just passing an array in the LV2_Feature data would be
enough for me.
Simple is nice, but somewhat closed ended.
How about simply passing a function pointer which converts a string to
an int? (in a Feature struct so things can be added for a more advanced
symbol system in the future)
Easier on the plugin author to just call a function than have to
implement that search all over the place anyway.
