Sunday Keys for MainStage does have certain system requirements for stable live performance.
We recommend MainStage Version: MainStage 3.4.2 or higher. You can also use MainStage 3.3, but Sunday Keys is optimized to perform in MainStage 3.4.
Recommended MacOS Version: Mojave. You can also use Sierra, High Sierra, or Catalina, but will likely achieve more stable performance with the Mojave OS.
8 GB of RAM or higher is recommended.
2.5 GB of hard drive space for installation. After initial installation it is possible to reduce the overall file size down to below 1 GB. Head over to the Sunday Keys Resource Page to find out how.
Sunday Keys does NOT require any third party plugins or instruments. Everything you hear in the demo videos and that you'll find in the download uses 100% stock MainStage plugins, our included custom sampled sounds, effects, and processing. You are welcome to use any third party plugins in Sunday Keys that you'd like to, though :)
The Korg nanoKontrol2 and TouchOSC aren’t required to use Sunday Keys, but both controllers come pre-assigned to the template and are great ways to interact with it live.
