Page templates in Dorico Pro allow you to achieve consistent page formatting by applying the same arrangements of frames to multiple pages and in different layouts.
Frames are boxes in which you can display text, music, and graphics. The default page templates contain a large music frame that takes up most of the page and text frames at the top and bottom. These text frames display different information according to the page template type.
All pages in your scores and parts inherit their default formatting from page templates. Whenever you change anything on page templates, such as inserting new frames, this is automatically reflected on all pages that use these page templates, provided those pages do not have page template overrides.
Dorico Pro provides different types of page templates so that there is appropriate page formatting for first pages independently of subsequent pages, as the first page typically includes additional information, such as the title, composer, and copyright. Dorico Pro uses tokens to display this additional information.
Page templates are contained in page template sets. By default, Dorico Pro provides separate page template sets for full score and part layouts. Page template sets are automatically applied to every layout that you create.
Changing individual pages in layouts is considered a page template override in Dorico Pro, which is a type of page format change. This includes, for example, editing the title or running header on one page, rather than in the page template editor. Pages with page template overrides no longer get updated if you edit the page template and are not automatically deleted, even if they are empty because the layout became shorter.
