Hi Ben,
If you have a full orchestra score, with Flutes 1 & 2 on one staff in the score and also separated out parts via partcombine, where/how do you place a dynamic then so that it applies to both locations without redundant markings?
The part-combiner actually does a great job of merging identical dynamics — no need (usually!) to do any extra work.
Specifically: I'm confused how to relocate the Flute 2's above-the-staff-dynamic in the full score to the normal under-the-staff location for Flute 2's part, single staff page. Do I need to input each dynamic mark twice?
No. The part-combiner *should* do that correctly (as I recall, from my rather heavy work with it several years ago).
