Hi, I am not sure of the function of Recording_group_engraver.  What
should I change, and how will it change the scheme code?
From looking at the c++ code it doesn't appear to do much.
If it records the time signature, then will it be added between the
other
events?


the Recording_group_engraver now records events. You could also record
changes to  properties.  The result is a vector, which is
read out from

  make-part-combine-music

(see scm/part-combiner.scm).


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?

Try process_music(). You will have to read the properties, check them against values in the previous time steps, and modify the data structure where events are stored to also contain property values.

source files that I should read to get more info?

Sure! They're in lily/*.cc  :)

In all seriousness: your question is too vague for me to answer.

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?

yes.
