SKETCHES for VECTOR SYNTHESIS

SKETCHES for VECTOR SYNTHESIS [2017][HD720] from macumbista

The VECTOR SYNTHESIS project is an audiovisual, computational art project using entirely analog synthesis and vector graphics display techniques to investigate the direct relationship between sound+image. Driven by the waveforms of an analog synthesizer, the vertical and horizontal movements of a single beam of light trace shapes, points and curves with infinite resolution, opening a hypnotic window into the process by which the performed sound is created.

This project is available as a live performance, a video installation or soon as a standalone audiovisual object crafted from handmade circuits and analog CRT tubes.

Informed by the discourse of media archaeology, my own personal interest in analog vector graphics isn’t merely retro-for-retro’s-sake. Rather, it is an exploration of a once-current and now discarded technology linked with specific utopias and dystopias from another time.

Sirene by Phillip Sollmann

Posted in Documentation on December 8th, 2016 by admin

sirene

In 2015 I had the pleasure of working with Phillip Sollmann on his performance/installation Sirene. For the project, I researched how to control two very precise, high-tech Faulhaber motors with Pure Data over a serial connection. Originally designed for aerospace use, the Faulhaber motors became the engines for Sollmann’s air-powered, microtonal sirens which were presented at Oststation, Vienna in the spring of that year. The physical structure of the sirens was designed and executed by Paper/Christoph Blattmacher in Berlin.

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.

VIDEO: SoundBoxes Workshop + Performance Berlin JUL 2015

Posted in Documentation on November 11th, 2015 by admin

SoundBoxes Workshop + Performance Berlin JUL 2015 from macumbista on Vimeo.

SoundBoxes are small, primitive electro-acoustic instruments built from a wooden box, a speaker, a small audio amplifier and a contact microphone. During the first of two workshop days, participants learned about electricity, how it becomes sound and then how to build their own personalized SoundBoxes.

On the second day, they explored the possibilities of the SoundBoxes through a series of listening and improv exercises, with the goal of collaboratively creating the score for an immersive, surround-sound performance inspired by the works of Alvin Lucier, Pauline Oliveros, John Grzinich, David Tudor, Gordon Monahan and others, performed in a darkened room for an eyes-closed audience.

In the piece, a swarm of individual, simple sound sources such as tones and textures are modulated and moved through the space physically by the performers to create a complex sonic environment. Delicate and intimate sounds pass closely near the bodies and ears of the audience, while stronger, more extreme sounds occur at the edges of the space to give a sense of the architecture of the room and the objects in it.

Signal Culture Residency

Posted in Announcement, Documentation on October 3rd, 2015 by admin

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.

Macumbista FuzzTone SoundBox

Posted in Announcement, Documentation on May 6th, 2014 by admin

A new generation of the SoundBoxes is born, combining the touchable body contacts and high-gain portable amplifier from the original design with a nasty distortion with enough controls to keep your fingers busy wiggling for a long while.

OVERVIEW

* Large, high-efficiency (read: LOUD!) 12cm speaker
* High-gain input, suitable for contact microphone, electric guitar, etc. (Line level signals can be attenuated if clipping is not intended.)
* Line output
* Neutrik 6.3mm (1/4 inch) jacks on both input and output
* Four-control, switchable, extreme[!], vintage hand-selected Germanium transistor distortion
* Six “circuit-bending” touchpoints
* 9V battery operation
* Includes a resonant spring contact microphone.

This SoundBox could easily be used as a portable guitar amplifier with built-in distortion, for example, or can be used as an instrument in it’s own right to create a wide range of electronic sounds and textures.

The sound of this instrument is quite similar to what can be heard in the following video (however the video was done with the SoundBox and FuzzTone distortion pedal as separate units). Through the creative use of feedback, as well as the CHP and SQZ settings on the pedal, generative tones and chaotic patterns can emerge:

The price is EUR 225 (incl. 19% EU VAT) / EUR 190 (shipped outside the EU) plus shipping. Each instrument is made to order with an approximately one month waiting time. A 50% deposit on the price is required to begin work.

MAAJAAM Weird Sound Workshop Estonia

Posted in Documentation on July 30th, 2013 by admin

From 13-16 July 2013, I led a small group of workshop participants to build their own electronic sound instruments–either the Weird Sound Generator (from the Music From Outer Space website), or one of my own SoundBoxes. The location was MAAJAAM, an experimental residency/workshop space initiated by Timo Toots in an old farmhouse in the Estonian countryside near Otepää.The workshop ended with a group presentation and invitation to the audience to play the instruments in the outdoor garden of the Genialistide Klubi, Tartu.

I would like to extend my admiration and gratitude to the hard work of the participants: Aivar Tõnso, Annabel Põder, Bianca Triinu-Toots, Kaarel Narro, Kalev Toots, Mihkel Tomberg, Taavi Suisalu and Timo Toots.

Duelling Benjolins

Posted in Announcement, Documentation on July 11th, 2013 by admin

Duelling Benjolins from macumbista on Vimeo.

Although I have been building Benjolins for more than one year, this was the first night I actually had two Benjolins finished at the same time. So of course I had to get them communicating with each other. As usual, please forgive the less-than-high-fidelity in-camera mic sound.

I’m taking reservations for four new hand-made Benjolin 2013v3 pieces to be produced in August. The design will be slightly different, more “modular” in style, with attenuators on all the control voltage inputs. Price should be EUR 495 (incl. 19% EU VAT) / EUR 416 (shipped outside the EU).

Let me know if you are interested, and thanks for your kind attention.
