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”. 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 low. That’s why there is a low humming wind noise between the “tops”. The output sound from filter goes to reverb. The sound is more a study of sloth behavior than an attempt to create a great wind sound.
