I have built a nonlinearcircuits sloth lfo, the regular version. Sloth is a chaotic lfo. The output is based on the lorenz system. It is a system of ordinary differential equations. It is notable for having chaotic solutions for certain parameter values and initial conditions. In particular, the lorenz attractor is a set of chaotic solutions of the lorenz system which, when plotted, resemble a butterfly or figure eight (very much from wikipedia). The sloth has two outputs x and y. Think of them as coordinate pairs. The output will probably never repeat itself but there is a pattern. I have built the regular sloth it usually takes approx 15 seconds to make a rough figure 8, one cycle in the “butterly”. The knob changes the chaotic pattern. At some settings the signals will spend more time in one strange attractor than the other. Now i’m testing the module in different ways. In this sound i have connected white noise to a filter. The filter frequency is controlled by sloth (x output). In this patch i have set the initial frequency at 12 o'clock. . . The output sound from filter goes to reverb.
