This allows my iPhone to do what I have always hoped it could do.

I have been able use this app and run all my show music and sound effects from the stage with no issues. All of the features are designed to make it easy to use and when I had to make changes on the fly I was able to within the app.

I asked the hosts in our theater if they noticed anything different about the show after using the app (we usually have a sound guy) since they see & hear the show often I would imagine that they would notice if anything seemed a bit off. They couldnt tell that anything was any different.

The app createor has been nothing but prompt in answering any questions or listeing to suggestions that I have offered. The update now puts this at the top of my app favorites.
