Random Looping Sequencer

September 26, 2012 · Posted in Uncategorized 

Here’s a demo of the Random Looping Sequencer DIY module. This patch features the RLS’ seq out multed to uscale in and envelator gate in. envelator out to borg 1… borg out to mixer and into camera. The sound source is the uncle & anti osc tripple wave folded and filtered with the z2040 and ems synthi filter clone.

The Random Sequencer is a circuit that produces random control voltages. These can be completely random, or they can be locked into loops that repeat every 8, 16 or 32 steps. It was inspired by the long history of shift register pseudorandom synth circuits, including the Triadex Muse, Buchla 266 Source of Uncertainly, Ken Stone’s gated comparator and Grant Richter’s Noisering. This circuit includes a transistor noise generator, so should create true random binary sequences. However, the structure of the sequencer and the nature of the digital-to-analog converter used seem to give a particular character – tones that rise and fall in a particular way.
