The video below provides an introduction to the Key Screen of the Motion Synth App (Multi-Key Version).

iPhone 4s: If you are using the Motion Synth App on an iPhone 4s you will notice that the Key Screen only has two additional circular buttons. These two buttons are designed to be covered up by the Key Divider (in order to prevent them from being accidentally pressed while you are playing). Tapping the button on the left (wrench icon) takes you to the Main Menu, while tapping the button on the right ('B' icon) brings up the bluetooth menu.

• Change musical scale on the Key Screen within the Notes Tab
• Adjust Key Screen for finger length
