My trial for Dorico has run out, so I can’t check this first-hand, and I didn’t find much when searching on the phrase “house style” in the forum, but is there an ability to export the musical options and Engrave mode settings as a house style that can be shared with other users?
I always hated the big bucket approach that Sibelius took with this and my ideal would be a text format that can be imported and exported. Then we could include only the exact settings that are important, leaving Dorico to use its defaults or user settings for others, and could check this into version control to revert changes and see the history of various styles as they are added to.
@benwiggy made a good point in another post (https://www.steinberg.net/forums/viewtopic.php?p=604423#p604423) - that Dorico could ship with house styles for different periods, such as “Renaissance”, “Baroque”, “Classical”, “2nd Viennese”, “Avant garde”, etc., and I’d welcome this. If nothing else it would be very instructive to import a Renaissance style into your work and see the differences in notation that are activated.
