This is the best sheetmusic app I ever tried. I can make small changes to the scores, highlight places where i often miss a key, I never drop a page from the stand again, and when i play in group , it's easy to hide or show other instruments !
Works, but ... MobileSheets works better for me. As a mountain dulcimer player I don't need all the scores available in Gustaf.
General performance increase.
Several bug fixes.
In-app access to the sheet music.
