RUNG DIVISIONS

PULSE DIVIDER & RUNGLER

Rung Divisions pairs a nonlinear feedback shift register* ("nlfsr" based on the core of Rob Hordijk's Benjolin) and a clock divider (CGS Pulse divider) in a small and tactile form factor.

​

Rung Divisions is designed to be an interactive coupling of linear (clock division) and nonlinear (nlfsr) methods for generating gates, triggers and cv - with means for the two to interfere with each other in interesting and surprising ways. The rungler receives its clock signal from the output of a gate bus, which itself fed from the pulse dividers.

It will take input from any signal that crosses 0.6V, and as both of the functions are fully analogue (solid state logic, no microcontrollers), they can run at any frequency up to 40kHz (there are lots of interesting tones that can be derived from a clock signal which is outside of conventional audio range).

​

Rung Divisions has thirteen unique but related chaotic and linear outputs that are derived from the relationship between three input signals. The outputs come in the form of gates, triggers, variable width pulses and stepped signals. Use them to feed a whole patch with complex rhythms, trigger fills, and cv, or, run it at audio rates for a variety of sub oscillations, vocal tract styled pulses, stepped chiptune waveforms and clocked chaotic noise.

​

If you've ever used a benjolin you'll know that this kind of circuit really excels when moving between audio and sub audio rates, with sputters of chaotic rhythms and unpredictable patterns - now you can interface those behaviours with any other equipment or type of signal you can imagine.
