Yes, it's a long way off.  I'm not intending to touch expressive
music performance at all in my PhD; rather, I'll make tools which
all humans to direct the computer's performance as easily as
possible.  (which may still not be very easy!)

The catch-phrase for this is "let machines do what machines are
good at; let humans do what humans are good at".  :)   Humans
aren't good at manually specifying physical parameters every 0.006
seconds, but they _are_ good at correcting the way that notes are
played (generally every 0.2 - 2.0 seconds, at least for monophonic
violin music).


As for other instruments: I'm hoping to get physical measurements
of a viola and cello during the summer.  It would be a blast to
work on other instruments (clarinet, oboe, horn), but that would
require physical modelling code for them.  At the moment, the only
open source code that I'm aware of for clarinet is STK... but as I
type this, I recall that although the STK string model uses an
algorithm from 1986, the clarinet one is 1998 or 2002.  So maybe
that's a feasible thing to investigate.
