As far as I can see the music events are recorded in try_music.  Which
method do I have to add to record property changes?  Sorry, I am not
so familier with lilypond internals.  Perhaps could you give me some
source files that I should read to get more info?

I read part-combiner, and I think it works as follows:
make-part-combine-music puts the events in noticed, and from there
it gets passed to the function determine-split-list.  That function
returns a list of moments and descriptions.  So I just need to change
the determine-split-list function.  Is that right?

Thanks,
Kristof Bastiaensen
