Ok, my first concern would be can I see the full sheet on the screen, and then can I read the music from the stand while the full sheet is displayed.
My conductor is using a full tablet pc to read the full score.
I use mine on regular music stands. Displays a full sheet. foreScore lets you organize music into groups in any order. Using blue tooth page turner I can turn pages without stopping playing. When I use it for piano I don't use the page turner since my feet are busy enough on the pedals. I pull my sets into groups every week in the order I play them. I just touch the corner of the iPad to turn pages. Easier than turning a real page.
To get your music into the iPad I used a scanning app. You take a picture of your music with it and transfer that into forScore. I probably have 300 or more sheets in it so far.
