Butterfly Benjolin

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. The double version, which I have named the Butterfly Benjolin, allows incredible amounts of chaotic cross-modulation between the two halves of the instrument.

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 two Neutrik 6.3mm (1/4″) output jacks, 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.

PRICE

The price of the Butterfly Benjolin is EUR 895 (incl. 19% EU VAT) / EUR 752 (shipped outside the EU) plus shipping. All my instruments are made-to-order, with approx 1-2 month waiting time, and require a 50% deposit to being work.

This long-take shows an example of symmetrical cross-patching between the two halves of the Butterfly Benjolin, and gives an idea of the self-modulation possible with this dual instrument.

CNC-BENJOLIN-TOP

As of summer 2015, all alu front panels of my Benjolins and Butterfly Benjolins are CNC-engraved (rather than hand-stamped as previously).
