That's right. And someone earlier in this thread mentioned the idea of 
sending a Pitch Bend event before each of the alternate-temperament 
notes ...

And MIDI just has note numbers, I don't think it has any inherent idea 
that any given note number is an octave higher or lower than another. So 
a 4-note scale and a 24-note scale would be the same to MIDI.
