 One of the most useful features of all is no features at all in the Henley libraries performance mode All user interface interactions are turned off except for the one thing you need during your performance Page turning. Let's take a look To enter performance mode first tap the screen to show the menu Then just tap the stage curtains icon. It's the first one in the list in the upper right of the display You're now in performance mode All of your settings for this score are now frozen. This means that the page background color print or custom layout Margins staff spacing movements on a new page and double page view are all set to your individual preferences for the duration of your performance if You use landscape orientation You'll see two pages side by side only if you've enabled double page view for that particular score If I go to a new score in which I do not have that enabled then you won't see the two pages The only feature available in performance mode is turning pages the top menu the metronome The recording icon even the dots at the bottom of your score are all disabled This is to ensure that nothing interferes with your performance You won't accidentally open the menu when you only meant to turn a page Note that two finger taps to play repeats work in performance mode Playlists also work. This is a great way to play a recital program To exit performance mode tap the top or the middle of the screen then Exit performance mode We think the new performance mode will let the technology disappear so you can focus all your efforts on your music Good luck in your concert
