Wrapped View

Switch the Score Editor to “wrapped view”. A single track/instrument on the display with the part moving to the next line when the edge of the page is reached. A typical “lead sheet”.

NB you can have multiple Score Editor windows open at the same time, each with their own set of tracks and their own viewing state.
