You may click on any instrument to play it and there should be some movement or color change which indicates the instrument being played. It should be responsive enough so you can play more quickly than other digital instruments. You may also use keys to play the instruments if you would like to create something with less mouse movement. 1, 2, 3, 4, 5, and 6 are keys you can press to play the instruments. If any of the instruments get too big, press the space bar to reset them to their original size. Have fun!
