I thought I'd reply on this since I've since had time to really try Good Reader out as a music chart reading program. It
seems to have all the ingredients for reading music charts well, but for me it does NOT fly, not when really using it while you're playing an instrument.
The organization is all very well done and good - pages are well defined and separated. But trying to turn pages with ANY consistency while playing an instrument - in my case, piano - is IMPOSSIBLE.
Note: when one tries this out just sitting in a chair, it performs flawlessly. You may wonder "What was he talking about? This is easy!" And I've tried all methods -tapping the corners, the bottom middle tap, and the full swipe method. It all comes down to this:
Executing the tap or swipe successfully requires a certain deliberateness or focus in your finger touch - a focus that is easy enough to summon when you're doing nothing else. But this focus, at least to me, is simply not accessible when I'm playing the piano and reaching in quick desperation to make sure the page gets turned in time. It's just not there for me anyways, and I predict that some might be able to do it, but I doubt even those few will feel any consistency in the results.
I have since discovered the Music Reader App and am currently trying that one. The App is free, but to work with charts and convert them on your computer requires that you purchase a program.
Thanks - and I hope this helps someone,....Frank
