click the black circle to change the sound/beat them click the red/green squares to change the speed of which the lyrics is going at. The save button saves the sound/beat you are on and plays it over and over again forever, you can then play other sounds or beats at the same time, keep in mind SAVE BUTTON ONLY WORKS ONE TIME.
