I’m sorry, I might be dumb, always asking stupid questions.
I read the notice, I search the forum, but still, I don’t understand how to proceed to have the big time signatures that I like.
I understand this is only for print ? You cannot have this option while working in writing mode, can you ?
You can set the design of large time signature with the Engraving Options dialog; here’s the manual page:
To turn them on in your score, use Layout Options. They work great, in either Page View or Galley View.
Like I used to tell my college students: "the only stupid question is the one you have and don’t ask."
