Allows you to scratch audio samples, just like a DJ scratches a record! It has several controls to vary the feel/technique, like turntable speed, hand speed, playback speed (+/- 50% instead of +/- 12%). Best of all, when you come up withsomething you like, you can output a WAV file (16bit/44.1k) of the scratch, to use in a song, answering machine, whatever!
