It seems to me, that physical modeling would be put to good (or
better) use attempting to design new instruments, not necessarily
synthesized, that had wider ranges of sound available to them. Horns
with white noise valves, finger triggered mutes (with tremolo!),
strategically placed pickups on strings (pickups inside strings),
resonant chorus of strings on double-reed instruments; whatever.
Use all those things like parameters for lacquer, wood density, string
alloys, and so on to build instruments that can approach the
requirements of the modern composer whether EA or written/acoustic.
Violins do pretty well already, but L. Shankar's 10 string acoustic
electric with full orchestra range and resonators is one example of
something new. Although I doubt there was any physical modeling going
on in the design.
