I don't understand – iBeams Music Visualizer Review

I can't get a large wave that covers the screen as shown on the preview images. All I manage to get are a bunch of red and blue balls that spin around. There are mild squiggly trails, but they are very faint. I did figure how to duplicate the balls, and I worked with the settings with each ball, but it's still nothing like the images on the preview pics. Help??
