System requirements: Sunday Keys App, MainStage and Ableton Live
Here's what each Sunday Keys format needs. Not sure which format is right for you? See Which Sunday Keys format is right for me?
Sunday Keys App (iPad and Mac)
Runs on iPad (iPadOS 15 or later) and Mac (macOS 13 or later). It isn't available for iPhone, Android or Windows. Plan on about 50 GB of free space to install the full Sound Library.
For details on models, processors, storage and connections, see What iPad or Mac do I need for the Sunday Keys App?
Sunday Keys for MainStage (Mac)
MainStage runs only on Mac. See Can my computer run MainStage?
Sunday Keys for Ableton Live (Mac or Windows)
You need Ableton Live Intro, Standard or Suite (not Lite). On an Apple silicon Mac, use Ableton Live 11.1 or newer for much better performance. See Which version of Ableton Live do I need?
