What the hell is this?? It's the idea of Shepard Tones ( http://en.wikipedia.org/wiki/Shepard_tone ), applied to rhythm. When you take a pulsating sound, and speed it up, eventually it becomes a frequency. You can do this with a delay pedal, where you turn the time knob down to 0. I wanted to make a pulsating sound that, when sped-up by a nice multiple (in this case, 5 times), is the same frequency as the original pulse. I had to introduce a second-degree pulse to make it seamless. I stacked a few octaves worth of this nonsense, and here you go.
