Welcome to the forum!

When you installed Finale, you also got some templates, located in the folder Templates.

If you, in Finale, go to

File menu > New > Document From Template…

then Finale will display a directory dialog box showing the Templates folder.

Inside the Templates folder there is a folder of Band Templates.

Ok, I know, but I would like to have other models!

Then I suggest that you create your own, custom templates.

In that way you can get the template exactly as needed.

A template is the same as a Finale document.

I do not know of a place where you can download templates, sorry

Here is the User Manual page listing the 70 current templates in Finale and how to create your own.

There are 3rd party Finale templates available from a number of sources. Typing Finale Templates in a Google search produces many pages of results at many price points.

Hi I found this interesting article regarding templates and document styles.
