Whether the signatures are in `arabic.ly` or in `hel-arabic.ly` is a purely technical decision. It doesn't affect the user interface in any way. I can only repeat: The user can select between `\include "arabic.ly"` and `\include "hel-arabic"` – it is completely irrelevant where the maqam definitions are actually stored internally. For example, a different layout could be arabic.ly: ... some setup for arabic ... \include "maqam.ly" hel-arabic.ly: .. some setup for hel-arabic ... \include "maqam.ly" Werner
