Looking forward to using it! – PitchFork Review

I really like the idea of this app. Siding to control speed and/or pitch is a great way to do it! Problem: I started up the app and selected a song from my library. I don't hear anything playing. I checked the Mute switch and the volume setting. Sounds come out of my iPhone, but not from this app. Suggestion: I don't see any playback controls. It would be great to have Play, Pause, Rewind buttons, as well as buttons to go back 5 seconds, 10 seconds, etc. This would enable using the app to learn a song or figure out how to play it on a musical instrument.
