Reinhold, I didn't see you get an answer.

There are examples in the documentation for tweaks, which are how you get
something inserted in a 'NoteEvent.

I'm not sure if you wanted a way to get the CrescendoEvent inside the Chord,
as opposed to outside the chord.  I don't think you can put the
CrescendoEvent inside the NoteEvent.

HTH,
