How can I reduce the number of pages? I having reduced space between staves, but now have big gaps at the bottom of the pages.
You might have to check the built-in help section of the software, because there is no mention on the Internet or on the official website. Typically, this should be solved by tweaking the Settings of the application. In the Help, go to Search and type page or space then read all the available topics. This is the only thing available for the software, as its details are pretty limited when it comes to usage guide or troubleshooting.
