“Noise Music in the Refugee Camp” – Kálmán Mátyás/Index.hu

Posted in Documentation on September 19th, 2010 by admin

The Ultrasound Festival organizers took special tour of Hungary, covering for a week the country’s most marginalized people. They visited the market Devecser, and afterwards the Bicske refugee camp.

UH Fest Go Social! Tour review

Posted in Documentation on September 14th, 2010 by admin

Introduction



Over four days at the start of September 2010, I took a small tour with the intention of visiting various socially-excluded groups in Hungary. This tour was organized by András Nun in the context of the upcoming UH Festival in Budapest, and I was joined by Luka Ivanovic (Lukatoyboy, Beograd), Balázs Pándi (drummer for Merzbow, Kilimanjaro Dark Jazz, Venetian Snares and others, Budapest) and Péter Szabó (Jackie Triste, Budapest), as well as by our translator Julcsi Palkovics and two photo/video journalists from Index.hu, András Hajdu and Kálmán ‘Mao’ Mátyás.

Each location visited related to András’ work with human interest NGOs, and he described the theme of our excursions as “Poverty and Exclusion in Hungary–or–What Can an International Festival Representing Peripheral Music Do About the Problem of People Forced to the Periphery, How Can It Act Against Their Exclusion?”

On Social Art I



I rarely hesitate in giving my opinion about the majority of “political” or “social” art projects I see at festivals and museums. Those that know me have often heard my joke about the Dutch media artist who reads the words “Problems of Muslim Integration” on the front page of the Volkskrant and “New Developments in GPS” on the technology page and–EUREKA!–runs off to win the Golden Nica at Ars Electronica.

The formula is simple: apply consumer gadget A to social problem B and it’s culture to absolve the middle-class guilt of the iEverything crowd, with kickbacks to Apple, Sony and Microsoft. In this European subsidized arts ecology, I have seen too many artists and institutions pay lip service to whatever the social-ill-of-the-day might be as a way of expanding their financial (and thus technological) resources from a different funding pool. And since the cultural money pools dry up quickest in times of crisis, I expect this kind of thing happens more often now than ever before.

However, while I cannot speak to the UH Festival’s organizational interests in having a theme like “Go Social!”, I can certainly point out András Nun’s deep personal interest in trying to combine the two very different worlds he lives and works in daily. So it was on those grounds that I agreed to take part.

Monor & Budapest





Besides the incredible range of groups we spoke to–in one moment we stood talking outside the run-down, windowless houses of dirt-poor Roma in the town of Monor, and in the next we jammed with young, hip Budapest 20-somethings at a walk-in drug treatment center–was the bewildering array of institutional approaches to these groups. One homeless advocate in Budapest insisted with all his naïve, youthful Marxist ideology that the solution to their problem was simply “housing, housing and more housing”. Likewise, the director of a homeless day center only focused on the necessities of food and clean clothing, without taking any interest in the individual psychic conditions which might keep people in those circumstances.

Faced with approaches such as these, the artist has little room to intervene. The artist’s work has nothing to do with policy, or even advocacy, but rather with the honest communication of human experience between one person and another. And this is an area unapproachable by those who reduce living people to demographics.

Esztergom, Vanyarc & Told






So I was much more at home in the locations where art had already found its place–places like Esztergom, Vanyarc or Told, where young people from poor Roma or Hungarian families could find the space and materials necessary for creative expression through painting, music or dance. It was a strange artistic match, however, for Luka, Péter and I to find a common ground with them.

We showed up delirious from many hours on twisting Hungarian roads at each place with loads of noisy electronic boxes, not knowing what sort of response to expect. In Vanyarc, the kids quickly lost interest in electronics and instead presented us with a program of Christian song and dance in the Gypsy style. In Told, on the other hand, the situation was beyond chaotic. Luka and I quickly agreed that we would have the children draw pictures of sounds from their village life and sing–or scream, as it happened–them for us as a conducted choir rather than try anything with his noise-toys.

On Social Art II



Early on in the discussion of this trip, I brought up some of my concerns about the typical media artist approach to social problems. They came in response to a project proposal which would see a homeless man carrying around a brand-new digital recorder, and these recordings sampled during a live set at the festival. With a nod towards Cornelius Cardew’s Scratch Orchestra and The Great Learning projects, which brought amateur and untrained musicians together into a structured improvisational setting and reflected his preoccupations with a kind of “people’s art”, I wrote:

“I think if this will really work, some strategies of how the people/groups you have chosen to work with could represent themselves–without flashy gadgets costing half an average month’s salary and ‘professional’ mediation–would have to evolve. The very nature of that kind of experiment means that the results you get may not fit the sophisticated aesthetics of your festival audience in Budapest, however. An interesting paradox, and one which I think is necessary to allow to happen.”

This paradoxical jump between poor rural families and sophisticated city music scenesters inflicted what Luka called a “social jet lag” on the tour group after the four hour drive back from Told. As we boarded the A38 ship and went below deck to see the Peter Brötzman Trio play, our usual world of stages, bands and nightclubs turned upside down and suddenly became far more surreal than the rooms full of messy, loud Gypsy children we’d become somehow accustomed to.

Lessons in Junk


Speaking with Róbert Bereznyei (Tigrics, Budapest) in his synthesizer-stuffed studio apartment one evening, we found agreement on one point in particular: to go to poor people in the countryside and show them how to make art with expensive gadgets is like dangling the keys to the Ferrari in front of them and then driving off. Any meaningful artistic intervention or collaboration must involve things they might actually have access to once we leave, whether those things are built on the spot, commonly available or provided by some institution already there. Róbert put it quite simply.

“Teach them build things from junk,” he said.

This kind of alchemical approach suits me well, and before departing to Hungary I went through many workshop possibilities in my head. All of them required far more time than we had at our disposal. The average visit to any one of these places was about an hour and a half, when in fact we could have stayed one or many days getting a feel for the situation and developing proper connections with the locals. As it was, it felt like something between a rock-and-roll roadshow and a group of camera-toting Japanese tourists seeing the Statue of Liberty one day, the Grand Canyon the next and Sunset Boulevard the third.

Devecser & Bicske





With all this in mind, we set out to the town of Bicske on the last day of the tour to give a sound workshop for young Afghan refugees. Before this, however, we took a six hour detour to Devecser, where the local Roma community run one of the largest outdoor bazaars for West European trash I have ever seen in my travels through the East. Here we picked up a few kilos of Chinese plastic trinkets, springy metal bits-n-bobs and total-kaputt-elektromüll, and then happily went on our way. If there is one thing Berlin has taught me, it’s that a great workshop always begins with a trip to the flea market!

Each of the Afghan boys in Bicske had some horrible unspoken story to tell… of murdered family members, of being smuggled en masse in the back of a truck through Iran and Turkey, of sleeping rough in mountains and forests for nights without end and–at the end of everything–of the ordeals of the Hungarian legal system. I swallowed hard, hoping none of that would matter in the moment, dumped a load of junk on the table and showed them how to use a contact microphone to get life out of these dead objects.

By the end of the afternoon, several of the boys had constructed small wooden sound boxes and one, before leaving to Budapest for evening Ramadan services, even expressed a desire to learn something more about electronics. There aren’t too many moments in life when one feels like a superhero, but perhaps this was one of them…

Soundbox One

Posted in Documentation on August 30th, 2010 by admin

Freshly made this evening for tomorrow’s journey to Hungary and the sound workshops that will happen there–the speaker box that is, not the little blue noise-synth, which was made in Norway last year. The reference to my Norwegian brother down South, Tore “Origami” Boe and his Acoustic Laptops is obvious. Testing with a contact mic and a distortion pedal produced amazingly rich and textured feedback possibilities!

Speaking of Boe, here’s a video from the workshop I invited him to do in Berlin in the summer of 2009 as part of the summercampworkstation project. Enjoy…

Analog Multiplier Module

Posted in Documentation on August 3rd, 2010 by admin

Overview

This synthesizer module allows “Buchlidian” style processing of three input voltages. It can do much of what the original Buchla 257 Voltage Processor does: addition, subtraction, multiplication and division. The only feature of the 257 it lacks is the ability to “transfer control” (i.e. interpolate) between the two different applied voltages

It contains one section with three attenuverting/bipolar inputs, which allow the user to sweep between the original signal on the right hand side of the potentiometer and an inverted version of the signal on the left hand side, with no signal passing through at the middle position. An offset control is also present to add a fixed DC voltage to the signal.

The other section contains an analog multiplier with three inputs, X, Y and Z, each hardwired to one of the attenuverting outputs. Output is calculated as follows:

W out = ((X1 – X2)(Y1 – Y2)) / 10V + Z

The panel contains two of each section. The X and Y inputs can be switched between AC and DC coupling, with an AC breakpoint of approximately 0.2 Hz, while the Z input is always DC coupled.

Schematic

Tom Bugs described himself as a magpie to me once in regards to his circuit designs, and while working on this module I have followed his lead. The “attenuverter” sections were designed by Chris MacDonald and modified by Peter Grenader, and have been further developed by Matthias Herrmann/Fonitronik.

Likewise the analog multiplier section is really just bringing every feature of the AD633 4 quadrant multiplier chip to the front panel, with some inspiration from Roman Sowa’s Ring Modulator design, as well as Marc Bareille’s adaption of that same design.

[click schematic to enlarge]

Usage

The AD633 documentation shows different applications such as simple multiplication, squaring and division as well as more complex tasks such as a linear Voltage Controlled Amplifier as well as 6dB/Octave Voltage Controlled Filters and a Quadrature Oscillator (both not shown here). The most common sonic use of this IC is for ring modulator circuits.

However, my main application for this is the creation of different kinds of transfer functions for use in chaotic synthesis. I discovered how useful the analog multiplier is while experimenting with the Doepfer system at KHM in Cologne. Multiplying two oscillators through a ring modulator, sending the result to modulate the first oscillator and using the first to modulate the second created an amazing array of unpredictable but certainly far from random results.

In most applications shown in the datasheet, the X and Y offset pins are grounded. But while breadboarding, I discovered that the X and Y offset gave a higher level of control over the modulations, so I built them into the panel. Likewise, switching between AC and DC coupling alters the resulting sound immensely, with the best results coming from one signal being AC coupled and one being DC coupled.

Adding one of the X or Y input signals to the Z input creates a kind of VCA which strengthens the effect. Or using another signal, such as a Low Frequency Oscillator with some suitable gain and offset, adds another modulation source into the mix to provide anything from amplitude modulation to clipping.

I believe this module gets at just about any type of processing the AD633 can do, as most of the time there is no attenuation, inversion, Z input or any kind of offset available on a normal ring modulator or analog multiplier.

Prototyping/Analog Computer Modules

Posted in Documentation on July 30th, 2010 by admin

I’ve been having some great correspondence with Jason R. Butcher about Buchla synthesizers, analog computers and chaotic synthesis techniques. He reminded me of a very special version of the Buchla 200 Music Box, created by Don Buchla for an electronics and cello work by Ami Radunskaya called Sili-Con Cello in about 1978 or 1979.

One of its features was a breadboard prototyping module, seen in the upper left corner. Here, Buchla created custom circuits to respond to the performance gestures of acoustic instruments in the era before Pure Data or Max/MSP.

[Photo from The Audities Foundation]

Jason showed me his own version of the breadboard module, which just happened to look a lot like a panel I spec’ed out last night. Here’s the completed module mounted in the case this afternoon. Each panel component (potentiometers and banana jacks) is routed to the terminals (the green areas), which in turn can be jumpered anywhere on the breadboard.

My first task with this module will be to design a “Buchlidian” style control voltage processor. It will contain one section with an attenuverting/bipolar input with offset and another section with an analog multiplier. The panel will have two of each section. It can do much of what the original Buchla 257 Voltage Processor does: addition, subtraction, multiplication, division…

The only thing it won’t be able to do is the “transfer control” (i.e. interpolate) between the two different applied voltages (although this could probably be done with a pair of Voltage Controlled Amplifiers rigged up as a cross-fader).

This new processor module represents one section of a larger analog computer project I plan to use for developing new chaotic synthesis techniques. The other sections would be a set of integrators (planned), an analog logic section (completed) and a suite of tools for working with digital pulses (comparators, clock dividers, digital logic and digital noise–all planned).

Of course, this prototyping module could also be used to lay out other kinds of non-linearizing functions to stick in the chaotic feedback paths. I’ll document those as they come up.

Discussions over the last year or so with Martin Howse continue to remind me that analog computers evolved out of the V2 rocket program and were mainly designed to control the flight path of missiles. In fact, just about anything used in electronic music has some sort of seedy military past. Our art is nothing more than a byproduct of the quest to more accurately drop bombs on each other, something I’m sure both Stockhausen and Kraftwerk were acutely aware of…

As for Mr. Butcher, check out his wild, live analog synthesizer project with Don Hassler. Buchla 200 Music Box vs EMS Synthi A, highly recommended!

Formanta Drone [surface noise]

Posted in Documentation on June 25th, 2010 by admin

Formanta Drone [surface noise] by macumbista

An older track from 2003, but one that I still appreciate. It uses the sample-and-hold noise-driven LFO of a Soviet-era Formanta EMS-01 synthesizer, digitally cross-bred with the surface noise at the end of a scratchy old Russian vinyl. Reflecting on this piece, I can see the start of a deep interest in automatic, generative and self-modulating processes taking shape. Thanks to Maksim Borisov for use of his amazing electronic museum piece! Originally released as part of the Karosta Project.
