NotePerformer: Add expressions for a1, a2, a3 etc

[Wallander]

It’s possible for playback templates to define new playback techniques and playing techniques that use them. In NotePerformer’s case, its expression map is already loaded by Dorico via the special mechanism that adds the expression map to the default library, so the same mechanism could be used to add other things to the default library, including playback techniques and playing techniques, if desired.

So you’re saying we can add Playback Techniques as well? That’s very interesting. I had no idea.

[dspreadbury]

Yes, indeed. Anything that’s added to the library file in the DefaultLibraryAdditions folder will be added to the default library.

Oh, right, playback templates can import all that, but that’s not the case with expression maps, right?

If you put them in that folder, they will be available too in any project. Quite useful
