On the Tempo Player screen , Press play! Start adjusting the tempo by moving the slider up or down and watch as the “New BPM” readout displays your new BPM. Use the Up and Down arrows to adjust the BPM in percent or number increments. Use the “Reset” button to return to the original tempo of your music.
The tempo adjustment range is ±50%.
To quickly jump tracks, simply tap the scrolling song title at the very bottom of the screen. It'll pull up a "switch to track" scroll that makes it easy to jump to a different song.
To "fast forward" or "rewind", simply tap the white circle in the time bar and drag it to the desired point.
