I often use piano apps to play/practice melodies and leads over iTunes songs on both iPad and iPhone. I can't seem to find a piano app that works with ireal book in 'play mode'. Appears to be a conflict when irealbook is playing a track....and no sound comes from the piano app.

This is a great way for me to practice when away from the piano and flying in the sky.

Has anyone any suggestions or know of a compatible piano app?
