Macumbista Benjolin 2013v2–now taking orders

Posted in Announcement on June 4th, 2013 by admin

The Benjolin is a standalone synthesizer designed by Rob Hordijk from the Netherlands. It contains two oscillators (one LFO and one VCO), a low pass 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 feedback systems within the Benjolin itself, a switchable external line input to the Benjolin filter and LEDs displaying the internal state of the Rungler.

For Spring 2013, I will produce five of these Benjolins, housed in antique wooden slide/dia boxes. One Benjolin from this run has been sold, and four more are available for order, with shipping on or before 21 June 2013.

This run is sold out!. These Benjolins are produced under licensed agreement with Rob Hordijk.

This instrument ships with an external 110V or 220V AC/AC converter wall power supply.

Please email MACUMBISTA at the domain GMAIL dot COM with orders and inquiries. Other customizations are available on request. Thank you for your kind attention.

A familiar old loop run through the filter section of the Macumbista Benjolin2013v2 via simple line-in modification. Filter cutoff frequency modulated by hand, by the two oscillators and Rungler sections of the Benjolin and by various control voltages available from the banana-jack patchbay.

Solstice SoundBoxes 2012

Posted in Announcement on December 2nd, 2012 by admin

I have been working on a series of SoundBoxes for sale and as gifts for the Winter Solstice 2012. These SoundBoxes contain a 1/2 Watt audio amplifier, a small speaker and a resonant contact microphone, all housed in beautiful antique cigar boxes or jewelry/silverware cases. Each box is unique and hand made, and bears the traces of its history as an everyday object before it was transformed into a primitive, intuitive feedback-sound-instrument.

This run of SoundBoxes is quite similar to ones which participants have created in my workshops over the last couple years. They can be used to create self-modulating drones, as seen in this video, or to bring out the hidden sounds within found objects as seen in this video.

Finally, as they run on a single 9V battery, you could make a portable concert with any other kind of sound input, such as a guitar, keyboard or smartphone. Some boxes include an line-output, “circuit-bending” style body contact points or a transparent, backlit speaker providing a window to graphical images or patterns inside the box, as in the Ghost Lockets series from last year.

Please contact me at MACUMBISTA at_the_domain GMAIL.COM (or use the contact page) during the coming week of 3-9 December if you are interested in purchasing one of these before 2013! I will be away from my studio from 12 Dec to 13 Jan. Prices range from EUR 50-90, depending on the box used and features included.

I have several styles of antique boxes to choose from (as seen in the first picture in this post), as well as the different added features mentioned. Some of the following boxes may also still be available, as noted. In addition, I can create made-to-order SoundBoxes from antique boxes in my stock at the moment.

All SoundBoxes come with a resonant spring contact microphone.

SET ONE: R.QUIRK COMMISSION

Set of four SoundBoxes, made in cedar cigar boxes and commissioned by Richard Quirk. The top pair includes a backlit 77mm transparent speaker, providing a view to two different antique Danish photographs from approximately the 1930s. The bottom pair uses powerful speakers to increase the physical resonance of the box and microphone. These boxes are SOLD.

SET TWO: SILVERCASES

This set of SoundBoxes are built into a variety of antique cases for jewelry, pens and silverware which have been found in Berlin and Paris. These feature black 92mm speakers and audio-responsive color LED lights. The textures of these cases are incredible, my favorite being the fountain-pen case in the top middle (which uses a minijack plug and 77mm speaker). The fountain-pen case and the box with the diagonal stripe, both pictured in close-up above, are SOLD. Besides those, all the rest of these boxes are available for sale.

SET THREE: LARGE SPEAKERS

In general, the speakers I use are either 92mm or 77mm wide, however occasionally I find large boxes and therefore prefer to use larger speakers. The top box once contained a set of silverware and now contains a set of six “circuit-bending” body contacts, while the bottom box still contains the aroma of tobacco. These are the only large-speaker SoundBoxes I am currently offering for sale. BOTH SOLD!!!!

SET FOUR: 77mm BOXES

These boxes are available for made-to-order SoundBoxes. They are drilled to use a transparent 77mm speaker. The inside of these boxes is lit by an LED, and images or graphics can be placed inside, as seen below in these examples from last year’s collection:

SET FIVE: 92mm BOXES

These boxes are available for made-to-order SoundBoxes. They are drilled to use a black 92mm speaker. I have several of the box in the rear-middle, marked “Pallas”, as seen below:

PAPER OPTIONS

These Japanese chiyogami 70g/m² patterned papers are currently available for decorating the interiors of the SoundBoxes which have transparent speakers. Other options include vintage photography prints, reflective paper (silver, gold), other found objects (bones, shells, reflective materials…) or custom graphics printed from your digital file.

Thank you for your kind attention.

Electric Spring

Posted in Announcement on February 12th, 2012 by admin

In what seems to be a time-honored tradition, I’m staying up all night before a 6am flight to my Electric Spring gig making new instruments. These I have named after both the festival and the resonant coil microphones they employ. Each one is a beautiful drone machine by itself, and when placed together they have a natural tendency to harmonize. This time I actually managed a line-out to connect to the mixer as well.

The performance is likely to be a live version of Nonlinearity III, as seen in this video, using all three SoundBoxes instead of clever editing to make the polyphony. My first SoundBox from Nonlinearity I may also make an appearance…

These three new Electric Spring SoundBoxes became available for sale after the concert in Huddersfield, 15 February 2012. Number one of three is already sold. Inquire via the Contact page.

SoundBoxes for Sale

Posted in Announcement on January 14th, 2012 by admin

UPDATE: SOLD the whole edition to a collector in the States. I will be doing future runs of SoundBoxes soon, watch this space or get in touch to reserve yours.

I wanted to remind my dear readers that the three SoundBoxes of the Ghost Lockets series are still for sale. Price is EUR 120 each plus shipping (and USt for German buyers). The Ghost Lockets are enhanced SoundBoxes, incorporating a circuit based on a fancy boutique guitar fuzz with a spring-mounted contact microphone, 9V battery, 1/2 Watt audio amplifier, transparent speaker and audio-responsive lighting. Each one also contains a Danish ghost.

You can see more detailed photos of each here. Videos of two other SoundBoxes can be viewed here (similar design, no distortion) and here (different design, but recorded with distortion pedal), and these should give you an idea of how they can be played and what they sound like. I can shoot specific photos and videos next week for interested buyers. Handstamped nameplate on request.

Ghost Locket Triptych

Posted in Documentation on October 12th, 2011 by admin

Mr. Dykshoorn was buried with his “divining rod,” a thread of piano wire that served, as he wrote in his book, “as an aid to my concentration” during case work.

–Matt Flegenheimer, Marinus B. Dykshoorn, Psychic, Is Mourned in Bronx, New York Times 10.10.11

Many systems of clairvoyance involve the observation of a delicate apparatus–a thin wire,  a stream of smoke, a candle flame or the hiss of white noise–which exists in a borderline state and is thus highly sensitive to the influence of forces both seen and unseen. The non-linear feedback loop between a loudspeaker, microphone and high-gain amplifier circuit responds dramatically to minute changes in its immediate environment, fulfilling the requirements of both a potentially chaotic system as well as the needs of the would-be psychic investigator.

The Ghost Locket Triptych was created between 7-11 October 2011 in Aarhus, Denmark for a battery-powered seance executed by Derek Holzer and Kristian Hverring on the evening of 12 October. These lockets use locally-sourced materials embodying certain historical resonances noted by the artist during his stay here. Internally, each locket contains a hand-built Germanium transistor distortion circuit, a 1/2 Watt audio amplifier, a small speaker, a source of illumination and an antique photograph–the ghost within each machine.

The artist remains indebted to a series of conversations with the estimable Mr. Martin Howse of London and Berlin for inspiration in these and other matters.

The three elements of the Ghost Locket Triptych will be available for sale individually or as a set following the performance in Aarhus. THE EDITION IS SOLD. Please contact the artist for more information.
