Wonkystuff RBSS

The rbss (random bit-shift sequencer) module is inspired by the famous "Turing Machine" Eurorack module by Music Thing Modular which in turn was inspired by many previous shift-register sequence generators.

When it is in stock, you can buy this module at Wonkystuff.

There are three controls:

  • rate — this is the simplest: this changes the frequency of the clock pulse appearing at the clk out pin. It runs from very slow to quite fast, and can be used to clock other modules too (e.g. SEQ or TRIG modules). (In order to trigger the rbss, the clk out pin must be connected to the clk in pin).
  • chance — this specifies the probability that the sequence will change, from 0 (never) to 1 (always).
  • length — this is the number of steps that will be present in the sequence, from 1 to 16.

Inputs are:

  • clk in — a source of clock signals. Every time there is a rising edge on this pin, the sequence shifts. This can be driven up to audio rates for some interesting noises!
  • len cv — The control voltage on this pin is added to the control voltage from the front panel length control (so if the front panel is fully clockwise, this voltage will have no effect)
  • chance cv — The control voltage on this pin is added to the control voltage from the front panel chance control (so if the front panel is fully clockwise, this voltage will have no effect)
  • bus clk — this is a repeater of the MIDI bus clk signal.

Outputs are:

  • a out — an audio-coupled output which will generate a pulse proportional to the difference in voltage between adjacent sequence steps;
  • cv out — a control voltage representing the current bit-shifted binary pattern;
  • clk out — a simple square clock signal
