Please read the instructions. Adjust the beats first and then click the black circle the amount of beats in a section (If the line on the bottom right is pointed to 4, click the circle 4 times). Click the bottom right corner's button with beats written to change the beats in a section. Click the rhythm you want. Make sure you don't click once and wait a long time then click again and wait really fast, if you do that the sound will not be what you except. When you click let go, do not hold it. Click the reset button to reset the beat and stop the sound. Hope you enjoy!!!
