OK. I know nothing about how to access Midi from Windows, so
hopefully someone else will be able to help there. But to
answer your most immediate question: yes, you can, if you
use ctypes (http://starship.python.net/crew/theller/ctypes/)
But it'll be a messy business trying to define all the
data structures etc., and I bet someone's already done
the hard work somewhere.

Have you tried the main Python list on comp.lang.python?
