This is an example on how I have padloops setup using Bossjock Studio app.  You can use these worship pad loops with something as simple as itunes to more indepth using Ableton or Mainstage.  For more information about padloops, listen to Episode 28 of the Leaders In Worship Podcast.

If you are an iOS user and do voiceovers, produce podcasts & more, you owe it to yourself to check out Bossjock Studio!
