Test tones are normally used by audio engineers to test the quality of either an audio signal or audio hardware. Used creatively, they can also make excellent instrumental samples and you’ll find them appearing on countless DJ ‘battle break’ records, usually at the end of the record on a continuous loop.
Try adding the following effects and scratching with them for some crazy sounds: Ring Modulator, Lo-Fi, Transpose Stretch, Formant Filter, Flanger or Filter FLO (for the dubstep wobble effect). Combine a few of these at once for some real madness!
