I forgot to tell you that the third dump line, which correspond to the 
key release, appeared *after* the undesired delayed note (I've kept it 
pressed about ten seconds).
So I think that the keyboard events are well interpreted by qsynth since 
I can play piano in a standard way: notes can ring as long as I want 
when I press/release the keys!
