If you've purchased the Sunday Keys Plus Bundle or Ultimate Sunday Keys Bundle, you'll have to do an additional step to download the rest of the Expansion Libraries.
- You can do this from Music > MainStage > Sunday Keys 2 where you'll see "Download Exp. Sounds" is the first item. Double click and you'll start downloading that content.
- You can do this inside your Sunday Keys concert in MainStage. Click on "Download Your Expansion Packs" and you'll want to make sure you have View > Show Inspectors selected and you'll be able to click on a link and download it.
- In either case, also make sure to also follow the steps on the installation page for Anthem Pianos.
