I think Aeolus does alternative tunings by essentially
recalibrating its
scale internally. It doesn't change the MIDI notes, though. So would a
synth using soundfonts be able to do the same thing? I presume a
soundfont contains at least one sample for each pitch, probably recorded
at a standard pitch (modern temperament) rather than some other tuning,
so how could such a synth change its scale?
That shouldn't really be any different from pitch bending, or playing
a soundfont where a sample covers more than one MIDI note. All of
these involve playing samples at some "wrong" pitch, and would happen
through some kind of resampling.
