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.

AUDIO DEMOS

Quick and dirty demo of Benjolin 2013v1, the first of several Benjolins to be built for sale in 2013.

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.

I am pleased to finally announce that I will be the co-curator of the next LAK Festival for Nordic Sound Art in Copenhagen, over the weekend of 26-29 September 2013.

My main contribution to the festival program is a series of workshops around the theme of the “Fifth Wall”. If the well-known “fourth wall” refers to the boundary between the artist and their audience, often “broken” through techniques of meta-narrative in theater and film, the term “fifth wall” could describe the boundaries between the audience members themselves during a shared artistic experience. The Fifth Wall Workshops series for the LAK Festival 2013 concerns itself with how this boundary can be broken within the traditional festival format of performance, installation and lecture, and in a world where almost everyone has become a digital art producer. These workshops emphasize participatory situations which transform festival visitors from passive receivers to active creators of sound art. Eventually, both “artist” and “wall” dissolve away, leaving the responsibility of presenting the workshop results with the participants themselves.

I look forward to sharing the list of invited workshop artists next month when everything is confirmed. Further information on the festival itself should soon be available at the following locations:

SOUNDBOXES WORKSHOP with DEREK HOLZER

DATE: 25 May 2013
TIME: 12pm – 7pm
LOCATION: Stpln, Stapelbäddsgatan 3, Malmö (map at : http://stpln.se/ )
PUBLIC PRESENTATION: 8pm (please invite your friends!)
COST: 100 SEK (plus one box to bring, see below)

Strictly limited to 12 places! Please register by sending an email to ljudlek (at) gmail (dot) com with ‘Soundboxes Workshop’ as the subject.

WHAT IT’S ALL ABOUT

Discover the hidden sonic qualities of objects from our everyday world in this hands-on workshop, combining the arts of electronics, noise, sculpture and collage. The basic elements we will employ are a wooden box, a speaker, a small audio amplifier and a contact microphone. To this, brave box-builders will add their own found objects, graphics, images, memories and ideas to create a unique electroacoustic cabinet of curiosities.

WHAT TO BRING

I will provide most of the tools and materials necessary for constructing the box, however there are a few things you should bring yourself:

1) A BOX (REQUIRED): This should be made of thin wood or very strong cardboard. No metal! This box should be a minimum of 10x10x4cm. Cigar boxes, small suitcases, instrument cases or jewelry/silverware boxes are all good things to look for.

IMPORTANT: The lid of the box should be no more than 5mm thick, to allow the hardware to be mounted.

2) A SPEAKER (OPTIONAL): If you want a speaker larger than the 92mm ones I will provide, you can salvage one from old hi-fi systems, clock radios or portable stereos. Please make sure it fits in the box you have chosen!

3) FOUND/SOUND OBJECTS (OPTIONAL): Please bring as many found objects as you can to decorate your soundbox or use as a sound source via the contact microphone. See VIDEOS and PHOTOS links below for inspiration.

ABOUT THE INSTRUCTOR

Derek Holzer (1972) is an American instrument builder and sound artist based in Berlin DE, whose current interests include DIY analog electronics, field recording, media archaeology and the meeting points of electroacoustic, noise, improv and extreme music. He has played live experimental sound, as well as taught noise art technology workshops across Europe, North America, Brazil and New Zealand.

This workshop has been organized by James Brewster with support from Kulturbryggan.

The Spring SoundBoxes are small, portable and battery-powered electro-acoustic instruments. They can create a variety of drone and reverb-type sounds through feedback between a small speaker and a resonant piezo-electric microphone, as seen in this video. Or they can bring out the hidden sounds within found objects as seen in this video.

These SoundBoxes are unique, handmade works of sonic art, made from German cigar boxes dating from the 1930′s to the 1960′s, and feature transparent and backlit 77mm black speakers, a resonant-spring contact mic, a line-out for recording and “circuit-bending” body contacts. They can also simply be used as cigar-box amplifiers for whatever other electronic instruments you might have.

Each of these SoundBoxes can be purchased for EUR 95 (incl. 19% EU VAT) / EUR 80 (non-EU) plus postage costs. Please include the number in the edition which interests you.

This is the second ten of an edition of thirty this season. The first ten, featuring a larger, black speaker, may be seen here.

Contact “macumbista” AT_THE_DOMAIN “gmail.com”. And thanks for your kind attention.

All boxes pictured have been SOLD. Please contact me for custom-order possibilities, I often find new cigar boxes which can be used for these instruments.

SOUNDBOXES WORKSHOP with DEREK HOLZER @ NK PROJEKT (BERLIN)

Saturday May 11 2013, 14:00-18:00
Sunday May 12 2013, 14:00-18:00

Discover the hidden sonic qualities of objects from our everyday world in this one day workshop, combining the arts of electronics, noise, sculpture and collage. The basic elements of this workshop are a wooden box, a speaker, a small audio amplifier, and a contact microphone. To this, brave box-builders will add their own found objects, graphics, images, memories and ideas to create a unique electroacoustic cabinet of curiosities.

No previous electronics experience is necessary for this workshop. Each participant is required to bring several items to the workshop, please see below.

WHAT TO BRING:

I will provide most of the tools and materials necessary for constructing the box, however there are a few things you should bring yourself:

1) A BOX: This should be made of thin wood or very strong cardboard. Plastic can be also used, but it doesn’t sound very good. And please, no metal! It is too difficult to cut and drill with the tools we will have. This box should be a minimum of 10x10x4cm, or bigger if you want to use a larger speaker or have more room to decorate and add objects. Cigar boxes, small suitcases, instrument cases or jewelry/silverware boxes are all good things to look for. At least one side of the box should be no more than 5mm thick, to allow the hardware to be mounted.

2) A SPEAKER (OPTIONAL): I will have a selection of speakers for participants to use. However, if you have something special please bring it along, but please make sure it fits in the box you have chosen!

3) FOUND OBJECTS: Please bring as many found objects as you can to decorate your soundbox or use as a sound source via the contact microphone. Bones, shells, small sticks, bells, strings, wires, springs (especially!) or anything else made out of solid yet resonant material make great sound sources. Photographs, cloth, leather, paper or any other kind of material can be useful for covering the box and making collages. Paint, markers and pens may also be useful.

SADLY, I WAS FORCED TO CANCEL THIS APPEARANCE DUE TO ILLNESS

Konspirationen #4.13

Fylkingen, Stockholm 13 April 2013

This gig comes at the end of a short residency at EMS Stockholm with Icelandic artist and instrument-builder Halldor Ulfarsson, whose eponymous “Halldorophone” augments the traditional cello form with a controlled electronic feedback system, allowing new tones and timbres to emerge from the instrument. During this collaborative performance, Berlin-based American sound artist Derek Holzer will insert the EMS studio’s legendary Buchla synthesizer into that feedback loop to further control and manipulate the sonic spectrum produced by this unique instrument.

I am finally able to offer the last three in the line of thirty Solstice SoundBoxes for sale, which I started in December 2012. The Solstice SoundBoxes were intended as small, portable and battery-powered electro-acoustic instruments. They can create a variety of drone and reverb-type sounds through feedback between a small speaker and a resonant piezo-electric microphone, as seen in this video. Or they can bring out the hidden sounds within found objects as seen in this video. A variety of other features were available, including transparent and backlit speakers, decorations within the box, line-outs and “circuit-bending” body contacts. They could also simply be used as cigar-box amplifiers for whatever other electronic instruments you might have.

I will also begin a new line of Spring SoundBoxes for 2013 very soon!

Autonomous Sonic Agents Workshop with Derek Holzer

In sonic terms, a “drone” can be considered an ongoing process which acts of its own accord. While this is commonly thought of as a steady tone or chord, much of my own work involves the creation of more complex, autonomous agents responsible for various parts of an audio composition. In this workshop, we will investigate different methods, involving loudspeakers, feedback and simple 9-Volt electronics, for creating such generative, self-playing sound systems. Each participant will construct their own primitive noise synthesizer, which they will present on the final day of the workshop. Please bring some type of wooden (preferred–cigar boxes are perfect!) or plastic enclosure to hold your circuit as well as any kind of speaker you can salvage from toys, radios, portable stereos or hi-fi systems.
