    Touch the iPad’s(and iPhone/iPod touch) screen to play a tone and watch how the pattern changes.
    When you touch the bottom of the screen the setting menu opens.
    In the setting menu, you can edit parameter such as the colour and opacity of the line and choose from pre-installed music pieces.

You can see your favarite sound.
