Apokalypsegerät 2013

Posted in Documentation on October 16th, 2014 by admin

I just realized that, although it was built more than one year ago, I still have not documented the Apokalypsegerät machine I created for Andreas Catjar and Markus Öhrn‘s theater productions, and which I play in Bis Zum Tod. I was probably waiting to edit some videos for it, but my video backlog is twenty miles long at this point. So here we go….. Please note there are some slight differences in panel layouts (and a couple extra functions added) between the proposal images and the finished system.

FEATURES

* Analog Modular Synthesizer with four Voltage Controlled Oscillators, four switchable Voltage Controlled Filters/Amplifiers, four Output channels and onstage lighting
* Optimized for the creation of apocalyptic doom drones

DUAL XR-2206 VCO

* Rough and Fine manual Tuning Controls
* Manual- and Voltage-Controlled Skew adjusts shape of the waveform
* Linear, Exponential and 1 Volt/Octave Frequency Modulation
* Sync input resets waveform
* Square Wave output
* Switchable Sine or Triangle Wave output
* Low Frequency or High Frequency Oscillator modes
* Circuit design by Thomas Henry, circuit layout by Bugbrand
* Two Dual XR-2206 VCO modules present in system

QUAD LOW PASS GATE 292

* Each of the four independent gates is switchable between Voltage Controlled Low Pass Filter, Voltage Controlled Amplifier or “Both” mode
* Used for Manual- or Voltage-Control over both amplitude and spectrum of audio signal
* High resonance allows generation of percussive sounds as well
* Circuit design by Don Buchla, circuit layout by Thomas White
* One Quad Resonant Low Pass Gate 292 module present in system

QUAD OUTPUT MODULE

* Each of the four outputs converts unshielded banana-jack to shielded 6,3mm audio jack
* Attenuators used to reduce modular synthesizer voltage level (10 Volts peak-to-peak) to line-level audio (3,5 Volts peak-to-peak)
* Female XLR connection provided for gooseneck LED lamp
* One Quad Output module present in system

I would love to do more custom systems like this, please contact me via the CONTACT link or at the email address MACUMBISTA at-the-domain GMAIL dot COM for more information.

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

Posted in Announcement on September 14th, 2013 by admin

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

http://radio0n.wordpress.com/

My apologies for those that couldn’t connect to the stream… no one told me it was limited to 10 people until too late! I have uploaded the two live sets and interviews as an edited MP3, total 59 minutes: http://tinyurl.com/mqlm3uc

This will be up until 08 August. Enjoy!

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.
