You can find demos of the Rolzer in previous posts here.

"Has a small blemish, clearly imaged above. Ships with power supply.
from CL:
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!"
