video upload by Chris Menes Sound

"A short demo of my 'Macumbista' sound box. Built at a workshop in London with sound artist, Derek Holzer a few years ago. It is a simple amplifier circuit with a speaker. The spring has a contact mic attached to it and it generates feedback when it's placed on the speaker. The touch points connect to various parts of the circuit so you can circuit bend it with your hands."

"Macumbista Fuzztone SoundBox Synthesizer Super Rare

Purchased directly from Derek Holzer of Macumbista

Rarely used and in perfect condition

Comes with Spring/Contact Mic

This was over an 8 month waiting list and they are no longer being made

Runs on a 9 volt battery

This has touch points and can be played alone as a noise source or you can use the contact mic or plug any line level source in and create

Full details from the Macumbista Website:

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"

Vector Synthesis: a Media Archaeological Investigation into Sound-Modulated Light


You might remember some of Derek Holzer's aka macumbista's vector oscilloscope videos, including a couple from Hainbach featuring the Vextrex, previously posted here.

Derek wrote in to let us know he has a new book coming out, currently seeking funding on Kickstarter here. Click through for additional details and demos.

"Vector Synthesis: a Media Archaeological Investigation into Sound-Modulated Light is a computational art project inspired by theories of media archaeology, by the history of computer and video art, and by the use of discarded and obsolete technologies such as the Cathode Ray Tube monitor. This text explores the military and techno-scientific legacies at the birth of modern computing, and charts attempts by artists of the subsequent two decades to decouple these tools from their destructive origins. Using this history as a basis, I then describe a media archaeological, real time performance system using audio synthesis and vector graphics techniques to investigate direct relationships between sound and image using analog CRT displays. Key to this system is a didactic, open source approach which encourages reuse and modification by other artists. The conclusion of the book reflects on how the project and the research surrounding it has contributed to the larger experimental audiovisual arts community through events such as the Vector Hack Festival.

Example videos from the project can be viewed here: https://vimeo.com/macumbista

Artists discussed include Mary Ellen Bute, Ben Laposky, Lyn Lye, Norman McLaren, Desmond Paul Henry, James Whitney, John Whitney Sr., Dan Sandin, Steina Vasulka, Woody Vasulka, Larry Cuba, Bill Etra, Mitchell Waite, Rosa Menkman, Cracked Ray Tube, Andrew Duff, Benton C. Bainbridge, Philip Baljeu, Jonas Bers, Robin Fox, Robert Henke, Ivan Marušić Klif, Jerobeam Fenderson, Hansi Raber, Ted Davis, Roland Lioni, Bernhard Rasinger, and the Kikimore group.

I wrote this book over the period of 2017-2019 as part of my MA thesis in Sound in New Media at Aalto University in Helsinki. It is 122 pages long, has 21 illustrations, links to several video examples online, and was fabulously designed by Claire Matthews.

I'm launching this Kickstarter because so many of you expressed interest in having a printed copy of this work. The proceeds of this Kickstarter (after covering the printing costs) will be used to get copies of this to people who have assisted in its creation, and just as importantly to organizations who deserve one -- places like Signal Culture in Owego NY; Cirkulacija 2, Ljudmila, and Project Atol in Ljubljana; the Radio Belgrade Electronic Studio in Serbia; the Media Arts and Technology Department at the University of California Santa Barbara CA; or the Media Archaeology Lab in Boulder CO, who either have directly contributed to the development of this project over the years, or whose missions correspond strongly with my own. My aim is to print and distribute 100 copies, or more if there is additional interest. Your support of this publishing project will help make that possible.

REVIEW

'The aesthetics of the Vector Synthesis project are timely and capturing: when our world has become as politically and environmentally problematic as it is, with the whole Enlightenment project under threat, art somehow has to express this, and Holzer does this by applying the aesthetics of the glitch, the broken, the old and dirty, but with the belief that there within we find meaningful contemporary expression. This is an aesthetic that questions the techno-progressive ideology, the perfect technological society of the future, and admits that our universalising narratives of simulation, control, truth and identity have become problematic.' Thor Magnusson, Senior Lecturer in Music, University of Sussex, UK, author of "Sonic Writing: Technologies of Material, Symbolic, and Signal Inscriptions" (2019, Bloomsbury)."

EMS Synthi 100 Oscillographics [Radio Belgrade Electronic Studio]


EMS Synthi 100 Oscillographics [Radio Belgrade Electronic Studio] from macumbista on Vimeo.

"This is a series of audiovisual X/Y oscilloscope patches for the EMS Synthi 100 at the Radio Belgrade Electronic Music Studio, and visualized on the Tektronix 5000 series modular rack oscilloscope. They were programmed to run autonomously without any human control. Most of them use two or three oscillators tuned to a close harmonic, and small changes in the frequencies (including temperature drift!) will make large changes in the image/sound. A couple use the Synthi 100's low pass filters as well. All are based on Ron Pellegrino's laser designs from "The Electronic Arts of Sound and Light" (1983)."

Vector Synthesis with Pure Data and the Vectrex by macumbista


Vector Synthesis - Disembodied Hand from macumbista on Vimeo.

"This video employs my Vector Synthesis library for Pure Data to produce an animated vector image using audio signals, which is then displayed on an XY oscilloscope. Here, the shape being displayed is a 3D OBJ file, rendered as three audio signals -- one for each of the X, Y, and Z axes -- with rotations applied to all three dimensions. Display monitor is a 1950's tube oscilloscope which got hot enough to toast bread during the making of this video."

More examples below - don't miss the last one. Vimeo still does not support playlists as far as I am aware of, so popping each one up individually here. Also see Vector Video Synthesis with a Vectrex and Cocoquantus by Hainbach.

8-Bit SoundBox


8-Bit SoundBox from macumbista on Vimeo.

"8-Bit SoundBox is an generative audio instrument which creates sound patterns from bits shifted around by a single, simple line of code. It is based on the 8-Bit MixTape project created in Indonesia by Lifepatch.org, as well as the analog SoundBoxes I have been creating since 2010. The analog SoundBoxes use touchpoints and feedback to produce circuit-bent drone sounds. The "one-liner" sonic bit-shifting code was discovered by game developers in the demo scene. More complex, layered sounds can be created by combining more players with more instruments. Eventually, the instruments will be able to communicate with each other wirelessly to aid collaboration.

Thanks to Andreas Siagian and Marc Dusseiller for support and inspiration!"

Macumbista Butterfly Benjolin analog modular synth

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"The Benjolin is a synthesizer designed by Rob Hordijk. It featrues two oscillators, a low pass filter and a random circuit of Rob's own design called a Rungler that outputs voltages, somewhat similar to a sample and hold circuit.

The Macumbista Benjolin is hand-built by Derek Holzer from Rob's circuit design. The Butterfly Benjolin you see here is actually TWO Benjolins together in one box. They are patchable via banana jacks. The cross modulation possibilities are endless.

This one is from 2014. Has the (discontinued) hand-stamped faceplate. Mine also has a mix output that uses the volume controls to blend both of the Benjolins and send out via a single 1/4 output. Very handy for showing up and plugging into an amp. Still has the standard single outs for each Benjolin as well. Comes with 6 banana cables.

I've taken very good care of it. No issues. Being a handmade instrument, it isn't perfect, but that's part of the charm."

Benjolin 2016 Pre-Orders Now Open


via macumbista: "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."

Macumbista Benjolin Circuit-Bent Noise Synthesizer Rob Hordijk Design

via this auction

"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 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. This particular Benjolin has BLUE CV/audio output banana jacks and YELLOW CV input banana jacks. The BLACK banana jack is wired through the volume knob to a 6.33mm (1/4") Neutrik output jack on the back.

You can watch a short demo of two of these Benjolins in action here: http://vimeo.com/70111383 [posted here]

The patchbay of these Benjolins has banana jack connections for the square and triangle waveforms of each of the two oscillators, the Pulse Width Modulation output of the two oscillators, the Rungler output, the XOR (exclusive/or) logic operation of the two oscillators and the output of the filter.

There are also banana jack control voltage inputs with attenuators for the frequency of each of the two oscillators and the filter cutoff frequency. The layout of the panel is designed to be both intuitive and playable (unlike many EuroRack modules, for example…). And finally, the three output bits of the Rungler have been visualized with red, green and blue LEDs.

All Benjolins use a Neutrik 6.3mm (1/4″) output jack, an additional GROUND banana jack to interface with other modular systems and a 12 VAC “wall wart” power supply (mainland European and North American versions available).

I have been personally producing these hand-crafted Benjolins for the last two years under licensed agreement with Rob Hordijk. You can see more about them on my website.

You can find more detailed information about the Benjolin, and about the Rungler function in particular, here."
