I purchased a piano lesson program from the web which is downloaded on my pc. I have tried everything I can think of to download this program to my ipad. It would be so great to just sit .y ipad on the music rack and work on the lessons. I tried dropbox and that did download most of the lessons bit dropbox can't open up the video lessons. Is there another app that will work with the dropbox or should I try a whole different direction? Thanks for any help you can give me.
