How to create a Drone Pad generator?

Anyone have any idea how to create a drone pad generator (like in mainstage or Ableton) in VST live? I want to be able to play a drone pad track in any key at a click of a button.

Sorry for the lack of information on the first post. I’m wanting to create a generator (like the photo attached below) where there is a button (or keyboard or midi controller key for a shortcut) and I can can click a button and play a mp3 file of a drone pad in any key. Thanks!
