In the middle of the OnSong menubar is a feature called the "heads-up display". This can be configured for different use patterns by swiping to the right or left over the area. You can swipe to choose the display you would like. You can learn more about each of these display modes in our user manual here: http://onsongapp.com/docs/interface/menubar/hud/
