Live compositions on oscilloscope: nuuun, ATOM TM

The Well-Tempered vector rescanner? A new audiovisual release finds poetry in vintage video synthesis and scan processors – and launches a new AV platform for ATOM TM.

nuuun, a collaboration between Atom™ (raster, formerly Raster-Noton) and Americans Jahnavi Stenflo and Nathan Jantz, have produced a “current suite.” These are all recorded live – sound and visuals alike – in Uwe Schmidt’s Chilean studio.

Minimalistic, exposed presentation of electronic elements is nothing new to the Raster crowd, who are known for bringing this raw aesthetic to their work. You could read that as part punk aesthetic, part fascination with visual imagery, rooted in the collective’s history in East Germany’s underground. But as these elements cycle back, now there’s a fresh interest in working with vectors as medium (see link below, in fact). As we move from novelty to more refined technique, more artists are finding ways of turning these technologies into instruments.

And it’s really the fact that these are instruments – a chamber trio, in title and construct – that’s essential to the work here. It’s not just about the impression of the tech, in other words, but the fact that working on technique brings the different media closer together. As nuuun describe the release:

Informed and inspired by Scan Processors of the early 1970’s such as the Rutt/Etra video synthesizer, “Current Suite No.1” uses the oscillographic medium as an opportunity to bring the observer closer to the signal. Through a technique known as “vector-rescanning”, one can program and produce complex encoded wave forms that can only be observed through and captured from analog vector displays. These signals modulate an electron-beam of a cathode-ray tube where the resulting phosphorescent traces reveal a world of hidden forms. Both the music and imagery in each of these videos were recorded as live compositions, as if they were intertwined two-way conversations between sound and visual form to produce a unique synesthetic experience.

“These signals modulate an electron-beam of a cathode-ray tube where the resulting phosphorescent traces reveal a world of hidden forms.”

Even with lots of prominent festivals, audiovisual work – and putting visuals on equal footing with music – still faces an uphill battle. Online music distribution isn’t really geared for AV work; it’s not even obvious how audiovisual work is meant to be uploaded and disseminated apart from channels like YouTube or Vimeo. So it’s also worth noting that Atom™ is promising that NN will be a platform for more audiovisual work. We’ll see what that brings.

Of course, NOTON and Carsten Nicolai (aka Alva Noto) already has a rich fine art / high-end media art career going, and the “raster-media” launched by Olaf Bender in 2017 describes itself as a “platform – a network covering the overlapping border areas of pop, art, and science.” We at least saw raster continue to present installations and other works, extending their footprint beyond just the usual routine of record releases.

There’s perhaps not a lot that can be done about the fleeting value of music in distribution, but then music has always been ephemeral. Let’s look at it this way – for those of us who see sound as interconnected with image and science, any conduit to that work is welcome. So watch this space.

For now, we’ve got this first release:

Vectors are getting their own festival: lasers and oscilloscopes, go!

It’s definitely an underground subculture of audiovisual media, but lovers of graphics made with vintage displays, analog oscilloscopes, and lasers are getting their own fall festival to share performances and techniques.

Vector Hack claims to be “the first ever international festival of experimental vector graphics” – a claim that is, uh, probably fair. And it’ll span two cities, starting in Zagreb, Croatia, but wrapping up in the Slovenian capital of Ljubljana.

Why vectors? Well, I’m sure the festival organizers could come up with various answers to that, but let’s go with because they look damned cool. And the organizers behind this particular effort have been spitting out eyeball-dazzling artwork that’s precise, expressive, and unique to this visceral electric medium.

Unconvinced? Fine. Strap in for the best. Festival. Trailer. Ever.

Here’s how they describe the project:

Vector Hack is the first ever international festival of experimental vector graphics. The festival brings together artists, academics, hackers and performers for a week-long program beginning in Zagreb on 01/10/18 and ending in Ljubljana on 07/10/18.

Vector Hack will allow artists creating experimental audio-visual work for oscilloscopes and lasers to share ideas and develop their work together alongside a program of open workshops, talks and performances aimed at allowing young people and a wider audience to learn more about creating their own vector based audio-visual works.

We have gathered a group of fifteen participants all working in the field from a diverse range of locations including the EU, USA and Canada. Each participant brings a unique approach to this exiting field and it will be a rare chance to see all their works together in a single program.

Vector Hack festival is an artist lead initiative organised with
support from Radiona.org/Zagreb Makerspace as a collaborative international project alongside Ljubljana’s Ljudmila Art and Science Laboratory and Projekt Atol Institute. It was conceived and initiated by Ivan Marušić Klif and Derek Holzer with assistance from Chris King.

Robert Henke is featured, naturally – the Berlin-based artist and co-founder of Ableton and Monolake has spent the last years refining his skills in spinning his own code to control ultra-fine-tuned laser displays. But maybe what’s most exciting about this scene is discovering a whole network of people hacking into supposedly outmoded display technologies to find new expressive possibilities.

One person who has helped lead that direction is festival initiator Derek Holzer. He’s finishing a thesis on the topic, so we’ll get some more detail soon, but anyone interested in this practice may want to check out his open source Pure Data library. The Vector Synthesis library “allows the creation and manipulation of vector shapes using audio signals sent directly to oscilloscopes, hacked CRT monitors, Vectrex game consoles, ILDA laser displays, and oscilloscope emulation software using the Pure Data programming environment.”

The results are entrancing – organic and synthetic all at once, with sound and sight intertwined (both in terms of control signal and resulting sensory impression). That is itself perhaps significant, as neurological research reveals that these media are experienced simultaneously in our perception. Here are just two recent sketches for a taste:

They’re produced by hacking into a Vectrax console – an early 80s consumer game console that used vector signals to manipulate a cathode ray screen. From Wikipedia, here’s how it works:

The vector generator is an all-analog design using two integrators: X and Y. The computer sets the integration rates using a digital-to-analog converter. The computer controls the integration time by momentarily closing electronic analog switches within the operational-amplifier based integrator circuits. Voltage ramps are produced that the monitor uses to steer the electron beam over the face of the phosphor screen of the cathode ray tube. Another signal is generated that controls the brightness of the line.

Ted Davis is working to make these technologies accessible to artists, too, by developing a library for coding-for-artists tool Processing.

Here’s a glimpse of some of the other artists in the festival, too. It’s wonderful to watch new developments in the post digital age, as artists produce work that innovates through deeper excavation of technologies of the past.
