DESCRIPTION

The VECTOR SYNTHESIS project is an audiovisual, computational art project using sound synthesis and vector graphics display techniques to investigate the direct relationship between sound+image. It draws on the historical work of artists such as Mary Ellen Bute, John Whitney, Nam June Paik, Ben Laposky, and Steina & Woody Vasulka among many others, as well as on ideas of media archaeology and the creative re-use of obsolete technologies.

SOFTWARE

During this workshop, you will learn how to use a custom library in the Pure Data programming environment to directly control the vertical and horizontal movements, as well as the brightness, of a beam of light. You will then explore Lissajous figures, waveform representations, and other multiplexed, audio-driven visual shapes and forms which can be displayed and manipulated in real time on an XY oscilloscope, Vectrex game console, ILDA laser display, and other analog vector displays using a DC coupled soundcard.

HARDWARE

We will also discuss hardware essentials such as how to modify a normal CRT monitor for vector inputs, how to hack together a cheap DC coupled soundcard, how to use a microcontroller such as the Teensy, Bela or Axoloti as a base for your vector synthesizer, and how to interface with the International Laser Display Association control protocol.

WHAT TO BRING

Please bring your own laptop. If you have a DC soundcard such as the MOTU Ultralight, please bring that as well. Many cheap USB soundcards can be adapted for DC use as well, you can find them on EBay or I will bring several for sale at the workshop. There will be a limited number of displays, so if you already own an analog XY oscilloscope, Vectrex game console, or other vector monitor, that would be very useful to bring. And finally, please get in touch if you have a CRT monitor you would like to see hacked (no guarantees!) during the hardware phase of the workshop. (Additional materials fee applies, we can discuss this.)

ATELIER MACUMBA presents

A NIGHT of PRIMITIVE ELECTRONICS featuring

GROWTH [DE]
RANDOM SONIC ATTACK [PL/GR/DE]
DEREK HOLZER + HÉLÈNE CANUET [USA/FR/DE]
The Students of SONIC COLLEGE HADERSLEV [DK]

plus DISTILLED SPIRITS by SLOWLANDS

17 AUG 2016 20:00 doors, 20:30 sound
55 Herzbergstrasse, Berlin-Lichtenberg

Event is held in the ground floor “cold hall”, next to the former Canteen.

GROWTH is a forest of ambiguities. It is an inward gaze, a state of being, and a largely improvised performance by the hands of Berlin based non-musician Lars Ennsen which may be classified in terms of minimal, ambient, and drone.

HÉLÈNE CANUET is a polymorphe French photographer, writer and performer. Rare on the art scene over 4 years , her work was only show in few galeries in Berlin. Lyrical, surrealistic or conceptuel her propositions are always very personal, almost intimate on the edge of poesie and social politic. Based on improvisation some of her projects seems done to snaked emotion and fired expectation.

Due to some studies at the Media Lab of Aalto University in Helsinki, I will be on hiatus for a while. Therefore:

I am no longer accepting any bookings for workshops or concerts until January 2017.

I am no longer accepting any instrument orders until June 2017, and even then my production line maybe undergo some changes.

Thank you for all your support as friends, customers and admirers over the last few years. It’s been a great ride. Watch this space or my more-frequently-updated Facebook page for updates: www.facebook.com/macumbistanet

PROJECT SPACE KLEINER SALON, BERLIN DE
2-3 APRIL 2016

Explore DIY electronics and sound art performance with your own SoundBox during this two-day workshop in Berlin-Kreuzberg.

SoundBoxes are small, primitive electro-acoustic instruments built from a wooden box, a speaker, a small audio amplifier and a contact microphone. They can create a variety of drone and reverb-type sounds through feedback between the speaker and microphone, or they can bring out the hidden sounds found within everyday objects. They also have small touchpoints which can be used to produce a variety of “circuit bending” sounds.

During the first day, we will learn about electricity, how it becomes sound and then how to build the SoundBoxes themselves. On the second day, we will explore the possibilities of the SoundBoxes, with the goal of collaboratively creating a score for a sound performance of approximately 10-15 minutes in length.

This workshop does not require any previous knowledge of electronics, only an interest and a curiosity in both sound and instrument-building.

Thank you for your kind attention.
Derek

I am now accepting pre-orders for the next run of Benjolin V3 and Butterfly Benjolin chaotic sound instruments. Pre-orders will be accepted up to 05 MARCH 2016 with a 50% deposit required. Projected delivery of this run will be mid-APRIL 2016.

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 are officially licensed by Hordijk, and 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.

PRICE

The price of the Benjolin V3 is EUR 495 (incl. 19% EU VAT) / EUR 416 (shipped outside the EU), and the price of the Butterfly Benjolin is EUR 895 (incl. 19% EU VAT) / EUR 752 (shipped outside the EU), plus shipping.

Please contact me using the CONTACT page here, or through MACUMBISTA at-the-domain GMAIL dot COM.

BOX OPTIONS

Current wooden box options for the Benjolin V3 are natural finish and “hammered” green, blue and red (limited supplies of all “hammered” finishes!!!!). The Butterfly Benjolin comes in natural finish only.

PANEL DETAILS

As of the summer of 2015, all the aluminum front panels of my Benjolins and Butterfly Benjolins are engraved and milled by CNC machine at the FabLab Berlin.

CUSTOM OPTIONS

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

CUSTOM TEXT ENGRAVING: rename your instrument with your own custom engraved text, up to approx 25 characters. EUR 15 (incl. 19% EU VAT) / EUR 13 (shipped outside the EU)

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)

Derek Holzer – MACUMBISTA [Vector Synthesis]

Solo performance for self-made analog synthesizer, analog vector video monitor and room by Derek Holzer. His live performances are largely improvisational journeys through different types of non-linear feedback processes, performed on a selection of self-made analog electronic synthesizers. He uses the unstable and chaotic patterns these machine create to explore the physical affects of volume, frequency and complexity within a given architectural space. During this live performance at SPEKTRUM, he will introduce some of his recent experiments in vector-based audiovisual synthesis. For fans of Maryanne Amacher, Bernard Parmegiani, Eliane Radigue and Slayer.

Marco Donnarumma – Ominous and Music for Flesh

In this performance, Marco plays two pieces with the XTH Sense , a biowearable musical instrument he created 5 years ago. By performing whole-body, physical gestures, his body emits bioacoustic sounds which are amplified using wearable microphone sensors, interactively live sampled and diffused through loudspeakers and subwoofers. In this way, he creates music by literally composing the sounds emitted by the muscle tissue of his body in real time. The natural sound of the flesh and its virtual counterpart blend together into unstable sonic objects. This is what he termed Biophysical Music, music that is a joint result of physiological technology and markedly physical, visceral performance.

ABOUT THE ARTISTS

Derek Holzer (1972) is an American instrument builder and sound artist based in Berlin DE, whose current interests include DIY analog electronics, the relationship between sound + space, media archaeology and the meeting points of electroacoustic, noise, improv and extreme music. He has performed live, taught workshops and created scores of unique instruments and installations since 2002 across Europe, North and South America, and New Zealand.

Italian born, living and working in Berlin, Marco Donnarumma is a performance artist, sound artist and writer. His work lies where performance art and sound art converge through technology. He has played interactive sound by amplifying sounds from his body, has induced visitors in altered states of self-perception by feeding sounds from their bodies back to their skulls and bones, has immersed audiences in multichannel sound and video produced by the strain of his muscles while he pulled 50Kg stones, and has physicalised digital viruses in the body. The focus of his practise is on how to configure human bodies and machines through sound. He uses biotechnologies, software algorithms and body sensors to create intensely physical actions, concerts and live installations which are renown for combining rigorous science, technical sophistication and critical thinking.

Broken Rope [Benjolin Vector Graphics test 3] from macumbista on Vimeo.

From 5-15 OCT 2015, I will be Toolmaker in Residence at Signal Culture in Owego New York.

While there, I intend develop a PCB which can be used for producing vector graphics, viewable via Vectrex, Wobbulator/hacked TV, laser display or other analog systems, which takes one or two audio inputs as well as control voltage. This board should include function generators, quadrature oscillators, phase shifters and multipliers, and could produce either traditional Lissajous figures using the analog multipliers or raster-type effects using synced function generators. The ultimate aim of the board is not only the development of artistic works, but also it’s use as the core of a future analog vector graphics workshop where participants both build and experiment with the circuit.

The lo-res sketches included here were created in September 2015 in Berlin using a vector monitor [V INPUT, H INPUT, Z-AXIS INPUT, PULSE MARKER INPUT] + Dual “Butterfly” Benjolin.
