cryptography (study I) from macumbista on Vimeo.
"The "Cryptography Studies" examine the use of simple analog implementations of pseudo-random number generators, akin to those used in encryption algorithms, for the chaotic production of sound patterns. One of the simplest pseudo-random number generators is a three-stage shift register with a non-linear feedback loop, such as that found in Rob Hordijk's "Benjolin" instrument design.
This one was built over Easter weekend 2012 as a starting point for further research on the topic. I have focused on the chaotic zones which occur when new parameters have been set by the controls or feedback patching, before the machine settles into a steady state and predictable pattern.
