Rolzer is a beat generator add-on for the , a drum and drama
machine. The Plumbutter offers complete voltage control of
all parameters, including its pulse-rolls, for generating
beat tempo patterns. However, when voltage control is added
to an androgynous circuit such as the rolz, it has the tends
to roll-off the ultrasound chaos present in the original
incarnation of this idea, the . So here we have the
Rolzer, a collection of geometries graded into tempi by
virtue of their capacitors. It is for developing a
relationship and searching for the oddest, most alive
rhythms, not by twiddling knobs but by making
connections.
Here we can bring back the strong sense of idiosyncrasy
only offered by non-knobbed geometries, without whimsey, by
collaborating with the industrial value system of capacitors,
known as "E6". Basically, a ratio of ten is broken
logarithmically into six gradations, and these are mapped to
a sense of tempo, associating Italian quality with Industrial
quantity: presto, allegro, moderato, andante, adagio, lento,
and grave become modules of 1, 1.5, 2.2, 3.3, 4.7, 6.8, and
10 microfarad values.
Now, each tempo module contains an assortment of
even and odd rolls. From top to bottom: hexagon,
triangle, square, pentagon, and hexagon again. There
are two hexagons to offer that roll's plexus for
connections. Before defining the colors, review the
sandrode concept- androgynous nodes that
neither input nor output, but perform both functions
at different times. In the rolzer, they are simply
transistor neurons, with three simple actions:
discharge of a capacitor, building up to a threshold,
and inverted pulsing another neuron. The
sandrode function is at the junction of these
three, forming both a sensor and a pulse generator.
The rolzer modules' majority of connections are
sandrodes, represented as brown nodes. In the
language of plumbutter, brown is both a hot and a
cool color, so it takes both those attributes, output
and input. However, sometimes you just want an
output, perhaps for voltage control of a manifesting
gong. So, each roll has one orange jack that yields a
square wave at the tempo of the roll.
Connections may be stacked, and since all the
plumbutter and rollzer outputs have a current
limiting resistor, anything can go into the brown
bananas. However, note that the brown bananas have no
current limiting resistor; this is essential to
propagate the paradox wave effect. The impedance of a
brown node feels like a diode junction to ground,
plus a high impedance to positive. As of 2014, I have
not received any complaints of broken browns, because
most sensible synthesizers have some kind of current
limiting resistor on their outputs. But make note
that if you have a very old Serge, you will likely
already know about its own smoking modules when
outputs are crossed, and that old warning would apply
when patching old Surge to a brown banana. In
general, the browns are meant to be patched with each
other, and connected to the green inputs of
plumbutter for drum machine manifestation. Likewise,
orange "should" go to blue or purple. And red and
gray can come back into the browns here. But
experimenting really can't hurt!
