Blackbinder format is a new and innovative digital way to work with scores.
Scores don't have pages. An automatic telepronter to read scores. And with all the necessary utilities for study, rehearsal and live performance. You can see more information at http://www.blackbinder.net and on its YouTube channel.
The scores do not download. Click on the one you want to use and it will appear directly in the App Blackbinder that you must have installed on your iPad.
