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!
