Well, it can be done with one form only, that will only make life
harder on those who don't want to truly understand non-12tET scales.

It may be messy if done wrong, but I strongly doubt anyone on the VST
list would agree that it is unnecsessary. They convinced me, at least.

It's not cleaner in any way, since for this to be useful, the plugin
has to figure out what scale it should ask about.
Again, there is no such thing as a single, global scale. If you
assume that, you may as well ignore anything about non-12tET
altogether.

Well, yeah - presets. Just like with any other plugins. A scale
converter is an *effect*, and deserves to be treated as such by the
API.
