To play the drums simply hit the power button and click or tap on any pad on the drum machine. You can also hit these keys to play: 4 5 6 7 R T Y U F G H J V B N M Change the global pitch of loops by using the left and right arrows below the pitch display. I left the bottom four pads with a blank sound. Add your own from the sound tab and change it in the sound block for each pad. Now make some beats!
