Gotta ask: re turning a page by swiping . . .

[nimbleswitch]

. . . When you swipe a page slowly, it appears to curl under your finger, like a real paper page might do. And you can see the "print" (chord symbols, etc.) showing through the page in reverse, like it would on thin paper. HOW the devil did you guys do that? I think I know WHY you did it (Because you could?), but . . . ?

Didn't mean to ask an awkward question. Just curious.

Apple provides us developers with tons of great frameworks.
In this case I used the UIPageViewController where you simply add the rendered song views as pages and it does all the fancy page curling and back side of the page rendering.

Thanks, Massimo. Amazing! And I still wish I could play bass as well as your bass algorithm. So many times it seems to know what tune I'm entering. Really well done. Many thanks.
