WOW! This cool tool is really going to be hard to explain! It will create and play (as well as record) any formula that you set it to. Options to apply echo, repeat "x" amount of times, loop play, set other parameters. You can create sounds then record/ save them to add as an effect or whatever use you might find. Just a cool tool to play around with as well as, I suppose, there would be some serious use for it too!
