As mentioned above, if utility tracks could be exported with the xml, then the import into musescore would have it all. Ms files allow for setting up the parts and score and print all in one go. It allows , as well,for editing individual parts that get updated in the conductor's score. It would be a great efficient workflow. Having said that, the legacy tracks provide for plenty, but I'd like the feature for big band arranging workflow to make the process less tiresome... One can only wish...
Anyways, don't forget the grapes. Happy New Year to all.
