MusicSoft Manager is an application for the iOS devices that allows you to transfer the song data straight to your instrument.
Transferring the song data to your instrument allows you to play music with lavish accompaniment. You can also slow the tempo of the accompaniment or mute the part for one hand so that you can practice at your own pace.
The colours and finishes shown may vary from those on the actual products. Some models may not be available in some countries.
