Casting off

“Casting off” is the term used to encompass fixing the layout of pages of music, such as setting the number of systems per page.

When calculating how much music can fit in each system and on each page, Dorico SE considers multiple aspects of the layout, including note spacing and vertical spacing settings. You can change these settings to change the default casting off in each layout.

In Dorico SE, you can set fixed numbers of bars per system and systems per music frame throughout each layout independently.

You can control the casting off at a more granular level by inserting system/frame breaks.
