Question

When creating choral music scores and splitting from 1-4 staffs to multiple parts (sometimes 12+) or back again, it seems like there should be a way to eliminate certain staff lines when they are not in use. It's really frustrating to want to split into 12 parts for a small number of bars in a 100+ measure song, but then have those empty staff lines occupy all the other pages.

Answer 1

Notion 5 will allow you to do an instrument change.  Simply click on shift + i on your computer keyboard to open the instrument change window.  Once you have selected the instrument that you wish to change to, it will be highlighted on your mouse pointer.  You can then click in your score, where you would like the change to occur.
