KR Player - AudioSheetMusic™

By KnowledgeRocks Limited

Open iTunes to buy and download apps.


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

Love it but

I love it so much it helped me passed grade one and two but on grade three I went to download the grade three book but it said that invalid KR player Overrated

Brilliant, Fantastic, Wonderful practising aid.

As a professional music teacher who has very much embraced the very exciting changes to my profession through modern technology, the advances do not get much better than the products being offered by Knowledge Rocks.
K R Player works brilliantly and has a growing library of material to purchase. I have been particularly keen on the Rockschool content but the potential is mind boggling.
Now.....once you have stopped jumping up and down with joy and if you are lucky enough to own an Apple Mac you must download K R Author (free!) which enables you to create your own files (audiosheetmusic). Very easy to use, excellent technical support. You can create excercises for your own personal use or if you compose or have the appropriate publisher permissions, upload it to the K R Player store and make some money. This app is a game changer for me no question.
