I wanted to let you know that I have tried the refactor-override branch and the overrides seem to be working fine! I do get a lot of warnings as you explained, but it does not appear the the EE overrides are getting overwritten, or maybe I'm misunderstanding your explanation?

Hi Jan-Peter,

Thank you for your work! I will test the changes later today and let you know how it results.

Hi Stefano,

I have been looking into the issue and created a branch
'refactor-override' for the edition-engraver.
The following is changed in there:
* Overrides are not applied "by hand" but send as a StreamEvent so
that once is handled by lily and not the EE
* Override (and Revert, Set, Unset) sent by the EE are marked so that
they can be distinguished from other overrides

That means once-overrides are note reverted wrong anymore and the EE
gives a warning if an overrides supersedes/overwrites an EE mod. This
is still not completely satisfactory when the EE shall override all
other settings. But at least it doesn't revert wrong.

If this branch is tested more thoroughly I will merge it into master.
Now I am looking for a way to let the EE be the last broadcaster so
that it will not be overridden by overrides sent from the actual music

How do you trigger the EE?  Overrides from the music stream are sent by
the iterators.  That's after start-translation-timestep and before

The EE broadcasts overrides (events) inside start-translation-timestep. I tried to do it in process-music, but then they were applied too late.
The EE is looking in its internal mod-store if there is something to do for this timestep (for this context). Is there a way to act between those slots - the latest action before process-music?
