Problem with letting the host worry about it is that the host would
normally not understand anything of this whatsoever, since the normal
case would be that a sequencer *plugin* controls the synths. It would
be a hack.
As to API, all there is to it is the existence of a note_pitch hint
for pitch controls, that suggests that the value *could* be
interpretted as something else than 1.0/octave. If you want
1.0/octave throughout, just ignore it and think of any pitch control
you see as 1.0/octave.
