forScore app
I’m really liking the forScore app for iPad. Scan in the music/chart, mark it up with an Apple Pencil in highlight or ink mode just like you would with paper, attach a Bluetooth pedal like my Coda Music Stomp to turn pages and you have a performance-ready solution without having to wrestle with physical sheet music.
My first attempt with this approach is the Jacques Delécluse 12 Studies for Snare Drum book and it’s working out nicely (copyright protected music shown for educational purposes).
