A particular example is the following:
I have a large orchestral score with lots of instruments, also e.g. two
horns.
- -) In the orchestral score, I don't want any cue notes.
- -) In the horn 1 and in the horn 2 instrumental scores, I want all cue
notes
(some are also from the other horn, e.g. the horn 2 score containes some
cue
notes from horn 1 in some places)
- -) In the combined horn score (which includes both horn1 and horn2), I
also
want all cue notes, except those referring to the other horn.
I tried to do something like that with \tag, but quickly gave up due to
the
complexity involved here and also since it can't be automated.
One of the most severe drawbacks of tags is also that you can't use
keepWithTag if you have more than one tag (since you can only give one tag
to
keepWithTag!). So you'll explicitly have to use removeWithTag for each and
every tag that you don't want. There is simply no way to say "remove
everything except those parts marked with tags A, B or C".
