I am a music teacher and would like to scan my music and load it on my iPad and then project it on my screen. I would like to also have the ability to circle notes and highlight parts of the music while it is projected on the screen so the kids can see what I am talking about. Are there any apps out there that I can load a score into, have the ability to draw on the music and also have the ability to swipe the picture and have it move to the next page without having to reload each picture individually. Any help or suggestions would be greatly appreciated.
