Macumbista Instruments Update June/July 2020

Posted in Announcement on June 27th, 2020 by admin

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.

Macumbista Benjolin V5

http://macumbista.net/?page_id=4770

The original Rob Hordijk Benjolin with some special modifications. They are licensed by agreement with Hordijk and lovingly hand made.

EUR 565 (incl. 19% EU VAT) / EUR 475 (for customers outside the EU), plus shipping costs.

Macumbista Butterfly Benjolin V3

http://macumbista.net/?page_id=4956

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.

Macumbista FuzzTone SoundBox

http://macumbista.net/?page_id=4372

A battery-powered, 1 Watt amplifier with Germanium transistor feedback and circuit bending touchpoints.

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

Macumbista Benjolin V5 available

Posted in Announcement on March 28th, 2020 by admin

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.

VIDEOS and PHOTOS

More images and video can be seen on this page: http://macumbista.net/?page_id=4770

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.

Macumbista Benjolin V5

Posted in Announcement on May 4th, 2019 by admin

Dear friends: I am about to start a building run of a dozen new Macumbista Benjolin V5 instruments, to be completed in July/August 2019. Features listed below. If you would like to order one of these instruments, please send an email to MACUMBISTA at the domain GMAIL dot COM with the subject line “Benjolin V5” for further info.

The Benjolin is a standalone synthesizer containing two oscillators (one LFO and one VCO), a voltage controlled lowpass filter (VCF), and a circuit called a “Rungler”, which allows chaotic cross-modulation possibilities between the different parts of the circuit. They have 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 external audio inputs to the Benjolin filters, two “loop” modes, and an external input to drive the Rungler clock.

The Benjolin V5 features a newly-designed PCB with a few improvements, namely that it can be powered from normal 12V DC wall supplies rather than the more exotic 12V AC supplies I used earlier.

Available box finishes are “hammered metal” green, gray, and blue paint, as well as a “natural” finish. Some examples of colors here:

Derek Holzer – MACUMBISTA [Vector Synthesis]

Solo performance for self-made analog synthesizer, analog vector video monitor and room by Derek Holzer. His live performances are largely improvisational journeys through different types of non-linear feedback processes, performed on a selection of self-made analog electronic synthesizers. He uses the unstable and chaotic patterns these machine create to explore the physical affects of volume, frequency and complexity within a given architectural space. During this live performance at SPEKTRUM, he will introduce some of his recent experiments in vector-based audiovisual synthesis. For fans of Maryanne Amacher, Bernard Parmegiani, Eliane Radigue and Slayer.

Marco Donnarumma – Ominous and Music for Flesh

In this performance, Marco plays two pieces with the XTH Sense , a biowearable musical instrument he created 5 years ago. By performing whole-body, physical gestures, his body emits bioacoustic sounds which are amplified using wearable microphone sensors, interactively live sampled and diffused through loudspeakers and subwoofers. In this way, he creates music by literally composing the sounds emitted by the muscle tissue of his body in real time. The natural sound of the flesh and its virtual counterpart blend together into unstable sonic objects. This is what he termed Biophysical Music, music that is a joint result of physiological technology and markedly physical, visceral performance.

ABOUT THE ARTISTS

Derek Holzer (1972) is an American instrument builder and sound artist based in Berlin DE, whose current interests include DIY analog electronics, the relationship between sound + space, media archaeology and the meeting points of electroacoustic, noise, improv and extreme music. He has performed live, taught workshops and created scores of unique instruments and installations since 2002 across Europe, North and South America, and New Zealand.
http://macumbista.net/

Italian born, living and working in Berlin, Marco Donnarumma is a performance artist, sound artist and writer. His work lies where performance art and sound art converge through technology. He has played interactive sound by amplifying sounds from his body, has induced visitors in altered states of self-perception by feeding sounds from their bodies back to their skulls and bones, has immersed audiences in multichannel sound and video produced by the strain of his muscles while he pulled 50Kg stones, and has physicalised digital viruses in the body. The focus of his practise is on how to configure human bodies and machines through sound. He uses biotechnologies, software algorithms and body sensors to create intensely physical actions, concerts and live installations which are renown for combining rigorous science, technical sophistication and critical thinking.

Signal Culture Residency

Posted in Announcement, Documentation on October 3rd, 2015 by admin

Broken Rope [Benjolin Vector Graphics test 3] from macumbista on Vimeo.

From 5-15 OCT 2015, I will be Toolmaker in Residence at Signal Culture in Owego New York.

While there, I intend develop a PCB which can be used for producing vector graphics, viewable via Vectrex, Wobbulator/hacked TV, laser display or other analog systems, which takes one or two audio inputs as well as control voltage. This board should include function generators, quadrature oscillators, phase shifters and multipliers, and could produce either traditional Lissajous figures using the analog multipliers or raster-type effects using synced function generators. The ultimate aim of the board is not only the development of artistic works, but also it’s use as the core of a future analog vector graphics workshop where participants both build and experiment with the circuit.

The lo-res sketches included here were created in September 2015 in Berlin using a vector monitor [V INPUT, H INPUT, Z-AXIS INPUT, PULSE MARKER INPUT] + Dual “Butterfly” Benjolin.

Miasmachine for Erik Skodvin

Posted in Documentation on April 25th, 2015 by admin

skodvin-01

The “Miasmachine” is a custom re-design of the Benjolin as a guitar-processing synthesizer for Norwegian musician Erik Skodvin (aka Svarte Greiner, half of Deaf Center and owner of the Miasmah record label). In this adaptation, the input signal is first run through a ring modulation circuit (with one selected raw oscillator waveform–TRI, PULSE or PWM–of the Benjolin being the modulator signal), then the ring-modulated signal is inserted in the Benjolin’s Voltage Controlled Low Pass Filter to control the higher harmonics.

This instrument was a custom commission, however if you are interested in a similar instrument, please contact me at macumbista AT THE DOMAIN gmail DOT com, or via the CONTACT page of this website.

I am still in the process of editing video for this machine, so this will be posted at a later date.

Last Benjolin of 2014

Posted in Announcement on December 10th, 2014 by admin

Meine Damen und Herren… may I present the last Benjolin I will build in the year 2014.

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 (produced under licensed agreement with Rob Hordijk) 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.

You can see more photos and videos here: http://macumbista.net/?p=3935

This Benjolin is completed and ready to move, and just to get it out into the world a little bit quicker, I am offering FREE SHIPPING anywhere on the planet, this week only (payment must be in by 13 DEC).

Price is EUR 495 (incl 19% EU VAT) / EUR 416 (shipped outside the EU). Contact using the CONTACT page here or email MACUMBISTA at-the-domain GMAIL dot COM.

I am looking forward to newer, bigger and better things in the coming year.

I thank you kindly for your attention.
Derek
