So I use my iPad to display Sheet Music. Works great except for the part where I have to touch the screen to turn pages. There is a Bluetooth Pedal that sells for $100 that does work. But that's $80 more than what its worth. I was thinking about possibly using a small Bluetooth Keyboard and lay that on the floor to turn pages. Yes, it will look strange. The fundamental question is ... does Page Up/Down on BT Keyboards work the same way on an iPad? In other words, do these keys register as next page / prev page within iPad apps. Anyone know? Thanks !!!
