Midi Controller Free

I want to like this but pressing on the Help button brings up a blank window with no help. And it isn't obvious how to use the app or what its capabilities are.

Perhaps this is a good tool for folks who know midi really well, but I was just trying to find a way to use my iPad to input notes into Finale. When I tried to create the connection and clicked on Help, there was no documentation, and the connection screen also provided no guidance. The marketing icon for this product shows a keyboard, but it is not in this app (or at least, not easily found). I am unloading this and trying another application.
