Jam Player is a simple-to-use, yet enormously powerful app that promises to make learning and practicing songs a lot easier by letting the user seamlessly manipulate the tempo and pitch of any songs.
Simply load a song directly from the iTunes library, i.e. playlist, album, songs and artist. Direct access, no need to import or other steps.
The Speed control knob can then be used to slow down the tempo of the song without affecting its pitch. For instance, a super-fast guitar solo could be slowed significantly to make it easier to learn, and then sped up periodically as the player becomes more comfortable with it.
The Pitch control raises and lowers the pitch but has no impact on the tempo, and it’s a great way for a singer who’s learning a song to change the key of the original track to match his or her vocal range.
Using the Speed and Pitch controls in tandem allows for manipulation of both variables. The app’s sophisticated pitch and time algorithms provide stunningly good results, even at extreme settings.
