Right.
Some plugins think in 1.0/note, and others in 1.0/octave. If you want
to connect them, you'll need "something" that expresses 1.0/note as
1.0/octave according to your scale of choice. Just as if you were
going to connect a MIDI controller to a CV synth.

You're missing that I'm not talking about 1.0/octave, linear pitch,

Changing it is totally pointless, since you'd still have note pitch.
Changing the "size" of one note is about as silly as changing the
"size" of one octave; that's my whole point. (1/12)/note for note
pitch *is* just as silly as 12.0/octave for linear pitch.
What I'm trying to say is that (1/12)/note
certainly doesn't look
nice in note oriented code, considering that there's *not*
nescessarilly 12 notes per octave:
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. ...and to
avoid both that *and* have 1.0/octave for linear pitch,
we have to do actual conversions whenever connecting these two
different kinds of controls.
Well, thats unavoidable for the general case. But, as we know the
converter for 12tET is trivial.
The only sensible way of doing that is by using
some form of
conerter plugins, IMHO. I definitely do not want to force host
callbacks into this.
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.
Exactly! :-)
