Six Macumbista Benjolin V5 instruments available in green, blue, and grey. Email macumbista@gmail.com for details.

All BV5 backorders shipping soon. Butterfly Benjolins next in the queue. Thank you all for your support in these strange days!

PRICE

The price of the Benjolin V5 is EUR 565 (incl. 19% EU VAT) / EUR 475 (for customers outside the EU), plus express shipping costs. Every Benjolin ships with two banana patch cables and a universal 110/220V AC to 12V DC power supply.

DETAILS

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 latest Macumbista Benjolin V5 instrument has been redesigned during the spring of 2019 in collaboration with Pete Hartman of Frog Leg Synthesis. The filter input has been improved, and the main output of the instrument buffered for lower noise and ease of use with a wider range of mixers and DI boxes.

The wooden enclosures used to create these handmade analog synthesizers all date from the 1960’s and 1970’s. There are individual variations in the exact color, the size, and the marks which history have left upon them. A number of different colors are available, including a natural finish as well as three different types of “hammered metal” paint finishes in grey, green, blue, and (infrequently) red or purple. Please see the photos at the bottom of this page for examples.

MODIFICATIONS

The Benjolin V5 contains the following modifications from Hordijk’s original Benjolin circuit:

LOOP SWITCH: The LOOP switch locks the otherwise chaotic pattern of the Rungler into a loop. The LEFT position is a loop of 4 steps going forward, the MIDDLE position is the normal chaos of the Rungler, and the RIGHT position is a loop of 4 steps forwards and 4 steps backwards.

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).

EXTERNAL RUNGLER CLOCK:: A banana jack on the back panel of the instrument provides a switchable clock source for the Rungler of the instrument. The EXT switch position clocks the Rungler from OSCILLATOR 2 of the instrument, the INT switch position clocks it from the external clock input.

The Vector Synthesis workshop, led by sound and light artist Derek Holzer over three full days, investigates the direct relationship between sound and image. It draws inspiration from the media archaeology of computer graphics, and from obsolete technologies such as the Cathode Ray Tube monitor, combined with contemporary laser display techniques. This workshop is ideal for musicians, sound artists, and visual artists who want to work with laser imagery.

Participants will learn how to draw Lissajous figures, render simple two- and three-dimensional shapes, and process photographs and video into vector artwork which can be displayed on oscilloscopes and ILDA laser displays using audio signals. These vector shapes can also be further modified in real time using external audio sources such as voice, amplified instruments, or electronic synthesizers provided by the participants.

The core of the workshop will be ready-to-use examples written in the Pure Data programming language.

A presentation of pieces created in the workshop is planned for the final evening, where participants will show their creations on the laser with sound.

The language of this workshop is English. The fee for the participants is EUR 50. The maximum amount of participants is 12.

Requirements

• Experience with Pure Data is not required to participate, beginners are welcome.
• Participants are required to attend all three days of the course
• Participants are required to bring their own laptops with software installed according to pre-event instructions sent by email.

I’m proud to announce the next Vector Synthesis workshop, taking place Feb 08-09 2020 at New River Studios in London.

The Vector Synthesis workshop investigates the direct relationship between sound+image. It draws inspiration from the media archaeology of computer graphics, and from obsolete technologies such as the Cathode Ray Tube monitor, combined with contemporary laser display techniques. This workshop is ideal for musicians, sound artists, VJs, and visual artists who want to work with oscilloscope or laser imagery.

Participants will learn how to draw Lissajous figures, render simple two- and three-dimensional shapes, and process photographs and video into vector artwork which can be displayed on oscilloscopes and ILDA laser displays using audio signals. These vector shapes can also be further modified in real time using external audio sources such as voice, amplified instruments, or electronic synthesizers provided by the participants.

The first 700 copy edition of the Vector Synthesis book has completely sold out. If you are one of the Kickstarter campaign supporters, or if you ordered a copy directly from me, I would like to thank you for making this book such a success. To keep it available, I have placed it as print-on-demand through the Lulu website.

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.

Book designer Claire Matthews and I got a Vector Synthesis print proof back last week, and since then we have been working like mad to get this publication ready for the printer. We have made so many improvements to the layout and flow of both the text and images, and I have also done several more rounds of corrections based on feedback from various reviewers. So now we really believe this is the best possible state this book can be in for sending for the final print.

   Over the course of this Kickstarter, the print run jumped from 100 to 700, and with that increase came a bit more concern from me over a few things–namely image permissions. I have sought permission to reprint most of the images in the book which came from other sources (something I would not have bothered with if it had remained a friends-and-family affair). This has lead to some interesting contacts with members of the David Tudor ensemble Composers Inside Electronics, or with Bill Etra’s widow Rozalyn Rouse Etra through the kind assistance of Benton C. Bainbridge. And in other cases I have redrawn or created new artwork from scratch (as with the Vasulka-esque scan processor examples at the start of this update) both to clarify images and to deal with the possibility that some image rights-holders may not answer in time (or ever!). This has caused a bit of delay in the publication process, but honestly I am very happy with the results and think that it is totally worth the wait and work.

  We aim to send this book to the printers in the coming week. Once I have the definitive delivery date, I will arrange for the shipping of the book to all of you, likely in the start of September. Copies of the book can still be ordered through me by sending an email with your postal address to MACUMBISTA at the domain GMAIL dot COM. I thank you all kindly for your patience and support.

   My best wishes from Helsinki,

   Derek Holzer

PUBLICATION FUNDRAISER:

The VECTOR SYNTHESIS: a MEDIA ARCHAEOLOGICAL INVESTIGATION into SOUND-MODULATED LIGHT book describes my research into the military and techno-scientific legacies at the birth of modern computing, and how early computer, electronic media, and video artists of the 1950’s, 60’s, and 70’s attempted to decouple these tools from their destructive origins.

It also presents my Pure Data software library and live performance project which employs audio synthesis and vector graphics techniques to investigate direct relationships between sound and image using analog CRT displays. The book 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 to print and distribute at least 100 copies of the book, to get them to people who have assisted in its creation, and just as importantly to send them to organizations and schools who deserve one. Your support of this publishing project will help make that possible.
