I have a composition that splits into two parts (separate staffs and lyrics) late in the song. Is it possible to do this in the middle of a work so that I don't have a staff that is blank until late in the song where the second line comes in?
The only success I have had is in creative printing where I print the first few pages without the second staff, and then print the rest of the piece with the second staff.
However, this is obviously cumbersome.
The explanation in https://forum.noteworthycomposer.com/?topic=249 is still valid today. At the moment, NWC supports only a static number of active parts in any single print job.
You could also refer to https://forum.noteworthycomposer.com/?topic=375 where the subject has been discussed too.
