I assume that just pasting this line under

Stream_event *event = note_events_[i];

is not the whole deal (I tried this, it didn't work).

I'm sorry to say, but at the moment I am writing C stuff by looking at some
engraver files and copy/paste everything into my file that looks as if 
it could
work. That's not really satisfying, but I try to learn it that way.
