Derek Holzer and Seth Zahn play “Animals (for two analog modular systems)”

“Time Lapse” event, Berlin Art Week, Altes Finanzamt
Schönstedtstraße 7 – EG Neukölln 12043 Berlin
U7 Rathaus Neukölln (Exit Schönstedtstraße)
Sat 21 September 2013 20:00

Think less Pink Floyd’s pigs on the wing, and more what you might hear if you could amplify the kind of animals seen under a microscope. A live improvisation, built up from scratch on Serge and DIY analog modular synthesizers and played at high volume by two performers with nothing to lose. Derek Holzer is an American sound artist and instrument builder who has made Berlin his home for several years, while Seth Zahn is a more recent transplant to this city’s experimental scene from Brazil.

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.

TOMORROW NIGHT — LIVE SYNTH SET for BEDLAM CHAMBER on RADIO ON

Posted in Announcement on July 30th, 2013 by admin

Live internet radio from NK Projekt Berlin, starts 20:00 CEST, Weds 31 July. The show will also be archived on the radi0n website.

“Several years ago, I abandoned the digital sound world to spend (quite a bit of) time building a modular analog synthesizer based on the forms and functions of the legendary Serge and Buchla systems from the 1960s and 70s. In performance, I summon the chaotic, generative powers of this machine to explore the physical affects of volume, frequency and complexity within a given space. For fans of Maryanne Amacher, Bernard Parmegiani, Eliane Radigue and Slayer.”
–Derek Holzer

Benjolin 2013v1 For Sale

Posted in Announcement on April 16th, 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 pair of band-pass filters and a circuit Hordijk calls a “Rungler”, which allows chaotic cross-modulation possibilities between the different parts of the circuit. This hand-made Benjolin has 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, as well as LEDs displaying the internal state of the Rungler. It includes a European power supply (other power supplies available on request). This Benjolin is for sale for EUR 400 (EU)/ EUR 336,13 (non-EU), plus shipping, and is produced under license from Rob Hordijk. Contact “macumbista” AT THE DOMAIN “gmail.com”.

This Benjolin is SOLD! Will be working on a few more in the coming weeks. Get in touch if interested.

Updated Migrating Art Academies Info

Posted in Announcement on March 15th, 2013 by admin

[Image: block diagram of the Triadex Muse, from "Musical Applications of Microprocessors", 2nd Edition, Hal Chamberlin (1987)]

The deadline for applications for the next Migrating Art Academies titled “Aesthetic – Responsibility – Drones” (2-7 May 2013, Berlin) is still a couple weeks away. We will select a few European participants to be sponsored with travel, accommodation and per diem.

Find info on MIGAA here: http://www.migaa.eu/aesthetic-responsibility-drones/

Info on my electronics workshop follows.

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.

ExperiMontag Performance, Monday 11 March 2013

Posted in Announcement on March 10th, 2013 by admin

Maulex [DK] turntables, textures
Jelena Glazova [LV] voices, drones
Derek Holzer [USA/DE] modulars, rooms

Mon, 11.03.13 21:00
Madame Claude Berlin, Lübbener Straße 19, 10997 Berlin, Germany

An evening of experimental instruments and deep sound textures at one of Berlin’s best-known nights for adventurous music.

-=Maulex=-

René Middelhede is a graduate student at DIEM (Danish Institute for Electro-Acoustic Music) and is working with drone and abstract textural music under the artist name Maulex.

It’s not music that flows rapidly from room to room, rather it moves slowly across the room and fills it with microscopic nuances that constantly change color.

The concert is based on an alternative use of the turntable as a medium. It is developed into an instrument by which complex textures and repetitive rhythms can be generated.

-=Jelena Glazova=-

Sound artist/visual artist and poet based in Riga, Latvia. Working in interdisciplinary areas of contemporary art, combining in her works image, poetic text, experimental sound and installation.

Experimental music activity field – noise/drone, usually constructed from processed vocals.

-=Derek Holzer=-

Solo performance for self-made analog synthesizer, speaker box, found objects and room.

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

Gig at O’Tannenbaum this Friday, Berlin

Posted in Announcement on January 16th, 2013 by admin

(Bread-burning synth photo by Terje Toomistu)

I will be playing a live improvisation for DIY analog modular synthesizer next Friday at O’Tannenbaum, along with bareth/stadler (Florinn Bareth–e-violin, Max Stadler–electronics) and Nicolas Humbert.

Info

Several years ago, I largely abandoned the digital sound world to spend time building a modular analog synthesizer which reinterprets and hybridizes the forms and functions of the legendary Serge and Buchla systems from the 1960s and 70s. During my improvisational performances, I summon the chaotic, generative powers of this machine to explore the physical affects of volume, frequency and complexity within a given space. For fans of Maryanne Amacher, Bernard Parmegiani, Eliane Radigue and Slayer.

TONEWHEELS HURDY-GURDY

Posted in Documentation on October 16th, 2012 by admin



TONEWHEELS HURDY-GURDY
(VIELLE A ROUE OPTOÉLECTRONIQUE)
DEREK HOLZER for ACCES(S) FESTIVAL
PAU FRANCE, OCT 2012

TONEWHEELS is an experiment in converting graphical imagery to sound, inspired by some of the pioneering 20th Century electronic music inventions, such as the Light-Tone Organ (Edwin Emil Welte, 1936 Germany), the ANS Synthesizer (Evgeny Murzin, 1958 USSR), and the Oramics system (Daphne Oram, 1959 UK). Transparent tonewheels with repeating patterns are spun over light-sensitive electronic circuitry similar to that used in 16 & 35mm motion picture projectors to produce sound.

The TONEWHEELS Hurdy-Gurdy presented at Acces(s) is not an “interactive” artwork in the common sense. While it does not reward the impatient museum visitor with flashing lights and noises at the simple touch of the button, it does invite participation in the process of technological music creation. Although it first appears to be a very traditional instrument known to many folk-music cultures, it functions in a very different way which can only be discovered by playing it.

The artist would like to thank Tobias Traub of Oroborus Customs e.K. and Carlo Crovato for their invaluable assistance in creating this instrument. Circuits designed by Jessica Rylan and Eric Archer are also used within the system.

More information on the TONEWHEELS project can be found at http://umatic.nl/tonewheels.html






INSTRUCTIONS

This instrument functions by turning light into sound. The audience is invited to experiment with it, provided that they read the following instructions and handle the instrument carefully.

—GETTING STARTED

1) Pick the instrument up by the strap and put it around your neck. You will hold the instrument as seen in the painting shown below, “Jeune fille à la vielle”, by Jules Richomme (1882). Please handle the instrument by the edges. Do not handle the triangular area in the middle, this area is very delicate!

2) Activate the power switch and adjust the volume knob at LOCATION A.

3) Using your the fingers of your left hand, locate the pressure-sensors at LOCATION B. When you press these, you will see different lights turn on at the center of the instrument.

4) With your right hand, turn the crank at LOCATION C. This will spin a wheel printed with transparent patterns. These patterns break up the light which falls on several light sensors, creating the basic tone of the instrument.

5) The sound of the instrument passes through a filter which can change its tone. The controls for the filter are marked in green at LOCATION D. The switch controls whether low, middle or high frequencies are passed through the filter. The controls marked “LFO” can be used to modulate the filter, while the controls marked “FIL” are used to affect the frequency and resonance of the filter.

6) There is also a distortion effect, marked in red at LOCATION E. The distortion only works when the large button has been clicked, and the red light is on. The four controls marked “DIS” control different aspects of the distortion.

7) When you are finished, please gently set the instrument down flat on the table and turn the power off.

—TIPS

1) The speed of the wheel affects the basic frequency of the sound
2) The filter and distortion shape that sound, but can also produce sounds of their own.
3) A good place to start is with the distortion off and all the controls set to the middle position.
4) There are some control settings which may not produce any sound at all!

FREIZEIT MACHT FREI

This hurdy-gurdy project might be the most complicated thing I have ever tried to build, involving quite a bit more technical research and development by myself and several others than I expected at first. All in all, we took about two months to build something that really needed a year to do right. Live and learn, unfortunately in that order. So when it was all over, and I finally had my first free day in ages, I took a little walk in les Pyrénées with Vincent Meyer
