Would it make sense to combine parts also when only one voice has
dynamics?  That could mean less work to put in the dynamics for each
instrument (if no separate parts are made).

That also makes me wonder if lilypond merges dynamics even when the
voices aren't merged.  That would be useful, since instruments in
the orchestra usually play the same dynamic.  (For example they
could be merged when the instruments have the same dynamic for a
longer time).

Ok, I'll look into it.

Thanks, for the quick reply!
