mutable marbles User Manual

Marbles requires a -12V/+12V power supply (2x5 pin connector). The red stripe of the ribbon cable (-12V
side) must be oriented on the same side as the “Red stripe” marking on the module and on your power
distribution board. The module draws 80mA from the +12V rail, and 20mA from the -12V rail.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
This device meets the requirements of the following standards: EN55032, EN55103-2,
EN61000-3-2, EN61000-3-3, EN62311.
Start with a clock – generated internally or divided/multiplied from an external clock signal.1.
If required, add some jitter to it, from slight humanization to complete chaos.2.
Split this randomized clock into two streams of random triggers to generate two contrasting rhythmic
patterns complementing the main clock.
3.
Generate three random voltages in sync with the rhythmic patterns obtained at the previous step.4.
Transform the random voltages to spread them further apart, or concentrate them around a specific
voltage.
5.
Add a pinch of lag-processing to obtain smooth random modulations… or quantization to get random tunes.6.
Steps 1 to 3 are handled by the left half of the module, the random rhythms being generated on the
outputs labelled t. In your Eurorack system such duties might have been performed by modules like Grids
and Branches.
Steps 4 to 6 are handled by the right half of the module, the random voltages being generated on the
outputs labelled X. A large number of modules would be necessary to patch this functionality: a triple
noise source and sample&hold, waveshapers, quantizers, and lag processors.
And now let’s take it further: what if everything the module did could be controlled by a slowly evolving or
lockable loop, like with Music Thing’s Turing Machine? That’s what the DEJA VU section is for.
Time to dive into the details!
