I'm thinking that a pull down bar from the top with buttons on it might be the way to go. You would just slide your finger from the top right or top left down (top middle might be a problem when I add continuous vertical scrolling of pages). This bar would basically just be a row of buttons that are shortcuts for things, like toggling on/off performance mode, annotations, or the metronome, or activating the annotations editor. Given enough time, it could be made flexible so that people could add the shortcuts to features they want. Thoughts?
