Layouts in Dorico
Layouts combine musical content, as represented by flows and players, with rules for page formatting and music engraving, and allow you to produce paginated music notation that can be printed or exported in various formats. For example, part layouts only include the music for that player whereas full score layouts contain all staves in the project.
A typical project for an ensemble contains several layouts. Typically, projects contain at least a full score layout that contains the music for all players and a part layout for each player that only contains their music. However, you can also create as many layouts as required.
By default when you add a player to a project, Dorico SE creates a full score layout and a part layout. For all subsequent players you add to the project, Dorico SE creates a part layout for each player and assigns them all to the existing full score layout.
Layouts can contain any combination of players and flows.
You can control practically every aspect of the visual appearance of the music in each layout independently, including staff size, note spacing, and system formatting. Each layout can also have independent page formatting settings, such as page size, margins, running headers, and footers.
The default formatting of pages in layouts is determined by master pages.
Deleting layouts does not delete any music from the project.
