Macumbista Benjolin

    Description
    The Benjolin is a standalone synthesizer designed by Rob Hordijk from the Netherlands. It contains two oscillators (one LFO and one VCO), a voltage controlled filter and a circuit called a “Rungler”, which allows chaotic cross-modulation possibilities between the different parts of the circuit. Hordijk refers to the Benjolin as a circuit which has been “bent by design.”

    These hand-made Macumbista Benjolins have been further customized with a patchbay, which can be used to interface with other modular synthesizers or to setup further control voltage feedback systems within the Benjolin itself, attenuators on the three control voltage input and LEDs displaying the internal state of the Rungler.

    FEATURES

    The patchbay of these Benjolins has banana jack connections for the square and triangle waveforms of each of the two oscillators, the Pulse Width Modulation output of the two oscillators, the Rungler output, the XOR (exclusive/or) logic operation of the two oscillators and the output of the filter.

    There are also banana jack control voltage inputs with attenuators for the frequency of each of the two oscillators and the filter cutoff frequency. The layout of the panel is designed to be both intuitive and playable (unlike many EuroRack modules, for example…). And finally, the three output bits of the Rungler have been visualized with red, green and blue LEDs.

    All Benjolins use a Neutrik 6.3mm (1/4″) output jack , an additional GROUND banana jack to interface with other modular systems and a 12 VAC “wall wart” power supply (mainland European and North American versions available).

    These Benjolins are produced under licensed agreement with Rob Hordijk.

    CUSTOM OPTIONS

    Additionally, there are a number of customizations available for PRE-ORDER ONLY:

    LOOP SWITCH: The LOOP switch locks the otherwise chaotic pattern of the Rungler into a loop. The UP position is a loop of 4 steps going forward, the MIDDLE position is the normal chaos of the Rungler, and the DOWN position is a loop of 4 steps forwards and 4 steps backwards. EUR 25 (incl. 19% EU VAT) / EUR 21 (shipped outside the EU)

    EXTERNAL INPUT SWITCH: The external input 6.3mm jack on the back of this Benjolin allows a signal from another source to be sent through the Low Pass Filter of the instrument. Selecting “EXT” on the FIL INPUT switch sends this signal to the FIL input, where the cutoff and resonance controls of the filter can be used to affect it. When the FIL INPUT switch is in the “INT” position, the PWM signal, mixed with a small amount of RUN voltage, is sent to the FIL (this is the normal Benjolin signal path). EUR 25 (incl. 19% EU VAT) / EUR 21 (shipped outside the EU)

    EXTERNAL RUNGLER CLOCK:: A jack of your choice (banana, mini-jack or 6.3mm jack) on the back panel of the instrument provides a switchable clock source for the Rungler of the instrument. The DOWN switch position clocks the Rungler from OSCILLATOR 2 of the intrument, the UP switch position clocks it from the external clock input. EUR 35 (incl. 19% EU VAT) / EUR 30 (shipped outside the EU)

    RUNGLER BITS OUT: Three colored banana jacks on the back match the colored LEDs on the front, and give a +5.6V gate voltage when the corresponding LED lights up. These are the individual bits of the Rungler, which are summed together through a simple Digital-to-Analog Converter to provide the RUN control voltage. EUR 25 (incl. 19% EU VAT) / EUR 21 (shipped outside the EU)
