KR Player - AudioSheetMusic™

By KnowledgeRocks Limited

This app is only available on the App Store for iOS devices.


The KR Player app offers a new approach to playing, practising and studying sheet music with synchronised audio tracks. Suitable for all ages, vocals, instruments, levels and styles of music. 

By combining PDF scores and matching audio into AudioSheetMusic™ we enable you to focus on the enjoyment of singing or playing your instrument rather than being distracted by page turns or finding corresponding scores and audio files on your tablet or computer.


AudioSheetMusic™ is our innovative and patented file format that combines PDF sheet music and real audio files into single interactive bundles - the marriage of digital score with MP3s.


The KR Player app was developed by professional musicians and educators with the goal of making your practise and learning of music a more fun and integrated experience. 

Always wanted to start playing an instrument or pick up where you left off or even breathe new life into your practice routine? 

We believe that the KR player app is the most user-friendly tool, allowing you to take your favourite AudioSheetMusic™ repertoire with you wherever you go. 


The KR Player app plays AudioSheetMusic™ with these benefits:

- Highlight bar (always shows you were you are and where you need to go next)
- Automatic scrolling (no need for page turns)
- Transpose audio
- Change pitch/time
- Looping
- Metronome mode
- Portrait/Landscape
- Zoom in/out
- Tunes in your library not dependent wi-fi connection


Our KR store (accessible ‘in-app’ and on any web browser) is ever expanding with high quality content from traditional publishers like Faber Music, Schott Music; exam boards like Rockschool;  record companies like Naxo; magazines like iBass Mag and Guitar Collectors Magazine and last but not least independent publishers, educators and artists like Bassline Publishing, Session Player, Scott’s bass lessons, Nicolas Meier Group, Paul Turner and Redtenbacher’s Funkestra.


Download the pieces that you want to play from our ever expanding KR store and interact with them with simple and intuitive gestures. You can enjoy the musical learning process by singing or playing your instrument rather than ‘battling’ with technology.


Please get in touch if you have any questions or suggestions - ping us at We are always happy hearing from you!

Practise. Play. Enjoy.

Customer Reviews

Great App

Awesome app with lots of features and a fantastic way to practice reading and also play different types of music. As a bass player I am more than satisfied with the selection especially the tracks from Redtenbachers Funkestra. You can't go wrong with any of their stuff it is always an absolute blast to play. Stefan writes some of the most fun bass lines I've ever played. Also the customer service is very good, I had a problem and was contacted immediately and they were helpful. You won't regret downloading the app!
