No, but if theres not 12 notes per octave then you dont need a twelve...
in 12tET were dealing with 12ths of octaves, so I dont htink the 12 will
be at all supprising.

Well, thats unavoidable for the general case. But, as we know the
converter for 12tET is trivial.

OK, fine, no host callbacks. The host could do implicit conversion though
it doesn't have to virtually insert a plugin. But this is probably a
per-host design decistion, it doesn't have to go in the API. Some users
(eg. me ;) will probably want to insert there own custom scale converter
plugins anyway.
