1. Display blank staves in any music frame by using the Flow Filter in Engrave mode (make sure the Frames editing mode is selected in the left toolbar).
  2. Create manuscript paper by filling the page with blank staves. Add a new Master Page that is not based on an existing pair; there is no need to make any changes in the Master Page Editor. Set your page to use this new blank Master Page. Now Dorico will not fill your pages with music, or the staves of added instruments. Draw out a music frame to fill the page (or as much of it as you would like to fill with blank staves), and choose Blank Staves from the Flow Filter.
  3. Optionally, you can set properties to influence the top and bottom padding, and you can choose exactly how many staves to fill the frame with.
  4. In Layout Options, set the staff size to change the rastral size of the manuscript paper.
  5. You could even save a Dorico project that has many layouts, each one using a different configuration or page size, orientation, staff size and number of staves.
