It is not perfect but I think that it is usable. The note parsing is
more robust if
you're not interested in real time. Currently my code requires a bit of
look-ahead, so that the note is delivered to the application only when
the algorithm is sure that a new note or a pause is has begun. This may
require an amount of time equal to the minimum duration of a note.
Depending on your application this may or may not be a problem.
Could I have a look at your student's code?

Ok, I'll try this approach first, altough tempo tracking it not so easy.

Ok.

Auch... have to study lisp too?! :)
(BTW, another application could be a front-end for the Mutopia search
engine)
