Henrik Frisk and myself are proud to announce a unique opportunity for students of KMH, KTH, and Konstfack to get involved with ongoing research into the history of electronic music in Sweden. The Sounds of Futures Passed workshop invites composers, engineers, and designers of sonic possibilities to investigate rare and unusual sound synthesis instruments formerly used at the Kungl. Musikhögskolan and Elektronmusikstudion EMS Stockholm.
We will speculate on what kind of aspirations for the musical future might have gone into the design and construction of these devices in the past, and on what sort of ideas about the use of sound instruments we can take from them into our own musical futures.
The workshop takes place over three ZOOM sessions (01 DEC, 08 DEC, 15 DEC), with team work taking place at KMH during the days between the meetings to compose with and analyze the functions of one specific instrument, the DATATON SYSTEM 3000 designed by Björn Sandlund in the 1970’s.
Students can send questions or register their interest in participating by email to idholzer AT THE DOMAIN kth.se and henrik.frisk AT THE DOMAIN kmh.se with the subject line: SYNTH WORKSHOP
This is the first in a series of investigations, each focused on a different historical device from the collected archives of EMS, Statens Musikverket, and the Scenkonstmuseet, with the goal of producing new, historically-informed sound synthesis instruments and interfaces. The project is supported by the Swedish Research Council/Vetenskapsrådet.

There have been some big changes for me in the last few months, and soon I will be moving to Stockholm to begin a PhD focused on recreating historical synthesizers used in Sweden during the 1960’s and 70’s. Before I move, I will do one last batch of instruments in July, to be shipped by mid-August.
If you have any interest in one of the following instruments, please get in touch by email to macumbista@gmail.com before Monday 06 July.
A double Benjolin with extensive cross-modulation possibilities including the ability to clock both Rungler control voltage generators from the same source.
EUR 1065 (incl. 19% EU VAT) / EUR 895 (shipped outside the EU), plus shipping costs.
A battery-powered, 1 Watt amplifier with Germanium transistor feedback and circuit bending touchpoints.
EUR 225 (incl. 19% EU VAT) / EUR 190 (shipped outside the EU) plus shipping.
A 50% deposit will be required to secure your order. All instruments ship from Helsinki, Finland.
This will be the final batch of instruments I sell within the foreseeable future. So if you have considered ordering something, now is the time to do it. Unfortunately, I do not have time for any custom work, nor for other instruments not on this list.
I wish you safety, health, and well-being during these wild times. Derek

I #staythefuckhome making analog synthesizers so you can #staythefuckhome playing analog synthesizers.
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.
Please contact me using the CONTACT page here, or through MACUMBISTA at-the-domain GMAIL dot COM.
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 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.
An Ebook PDF version is also available. Please note that Lulu is responsible for the shipping and handling of your order. For wholesale orders, please contact me directly for a discount.

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.
