Awesome
Essential app for any iPad musician. I was going to get a hardware loop machine until I discovered this app. So many more possibilities.
Update - This app is the best live looping app out there. I have tired several and always come back to Loopy. It is stable, unlimited amout of Midi routing. The developer has continued to support the app through the years with updates and features.
