Well the code works to generate "X" note heads. But the code doesn't
change the MIDI instrument on the fly. It's always the "acoustic grand"
in the ear. I replaced "synth drum" by "woodblock" and it works! I don't
understand why it didn't before.

But I don't need "synth drum", there is no matching MIDI instrument
anyway. I would need the sounds of knocking and tapping on the harp 
body. And I would like to set the instrument for the other notes to 
"harp" (MIDI channel 146).
