Hi Atte!

I think the problem was that the event that broadcast in Zone.listen() 
is not the same one that InstrSine.listen() is waiting on.  I have 
attached a slightly revised version which seems to work here.  Most of 
the changes is in Zone.  For clarity, I also capitalized the class 
names and prepend some member variables with 'm_'.

I think this is a bug in chuck: sporking a member function from inside 
another function.  Sorry about that!  The work around is to spork a 
non-member function and pass it the appropriate data.  We plan to have 
it fixed soon.

Hope this helps!
