If you’re using Keyscape as the only virtual instrument in your live rig, the Keyscape standalone app is ideal. It’s extremely stable, uses less CPU than most hosts (since there are no extra features to tax your computer), and you can magnify the GUI and open it in Fullscreen mode for easy viewing.

The Standalone also includes Flow Capture —an excellent way to record your performance—audio, MIDI (including tempo changes), and the sounds you used.

If your set requires other virtual instruments, effect plug-ins, complex MIDI or audio routings, or pre-recorded tracks in conjunction with Keyscape, you’ll need to use a host such as Ableton Live, MainStage, Gig Performer, or Camelot. These applications have plenty of features to create sophisticated performance environments.
