Install monthly Sunday Keys updates (MainStage and Ableton Live)
While your Sunday Keys License is active, you get a new Sound Library update every month, usually on the first Tuesday. In the Sunday Keys App, updates arrive in Menu > Sound Downloads Manager. For MainStage and Ableton Live, install them yourself:
- Sign in at SundaySounds.com and go to My Purchases.
- Find your Sunday Keys License and click View Updates.

- Next to the update you want, click Download MainStage or Download Ableton Live. Each update is its own download, so install them one at a time, oldest first.

- Install it:
- MainStage: open the installer from your Downloads folder and follow the prompts. The new Sounds go straight into Patch Builder. Look in the Recently Added folders to find them.
- Ableton Live: unzip the download, then follow this video to add it to your Sunday Keys project.
Missed a few updates? Install each one, oldest first (recommended). Or download a fresh copy of Sunday Keys from My Purchases, which always includes every update. A fresh install replaces your customizations, including MIDI assignments, template changes and your own Patches and Sounds, so only do it if you're OK losing those. You'll also need to repeat the setup steps on the MainStage resource page or the Ableton Live resource page.
