Ability to Transpose via CLI
This is probably a bit on the ridiculous side of things, but I figured it wouldn't hurt to ask.
I'd like to be able to transpose a score and its parts via the command-line interface, and export the result to a separate file. So if I provided a score that was in like, Concert Bb, I could say:
musescore -i SongName.mscz -transpose-up D -o SongNameInConcertD.mscz
which would transpose the entire score up a third, or
musescore -i SongName.mscz -transpose-down D -o SongNameInConcertD.mscz
which would transpose the entire score down a minor 6th.
