Beat Lab is a free service through which you can experiment with thousands of sound and rhythm combinations. Using Beat Lab is easy. Beat Lab provides a grid on which you select the sounds you want to have played. You can specify how often you want each sound played and how quickly you want the sounds played. There are twelve default sounds provided in the Beat Lab grid. You can add more sounds by selecting "add more sounds" and choosing from the huge catalog of sounds. If the sound you want isn't available in the Beat Lab catalog you can upload your own sounds.
