About Digital Books (eBooks)

Format: Our digital books (eBooks) are viewable in our free reader apps, available for iOS and Android devices, as well as our web browser-based book reader (no app required). We offer books in this format in order to provide enhanced audio and video integration, not available in standard pdf formats. Our digital books are not delivered as pdf files and are not printable. They are intended as 100% digital products without a physical component.

Printing: Printing is not available for our digital books, which are designed as digital-only products. While many of our digital books have identical print edition versions available, many are available in digital-only format.

Audio: For digital books that feature audio, you simply tap a given stave of notation and audio playback will begin. We also provide stand-alone audio files for you to download, for increased flexibility (available only for digital books purchased directly from fleksproductions.nl. Not available for digital books purchased using in-app purchase).

Video: For digital books that feature video, you will be able to view them directly within the digital book. We do not provide stand-alone video files for download at this time.

Internet Connection: To access your digital book and to access audio or video within digital books, your device will need to be connected to the internet. Media is streamed into the books in realtime, to help keep our downloads small and fast, and reduce the amount of storage space used on your device. An active internet connection is required to access and view digital books.

Refunds: We are not able to issue refunds for digital purchases, including digital books and instant video. Please click here to contact us if you are having an issue with your purchase and we will work to resolve.
