Back, behind-the-scenes, I still have some articles in draft form that both detail the nuts’n’bolts decision-making processes in the construction of a machine improviser, and self-reflective critique such constructions, detailing the trade-offs and shortcomings of such an entity, and its design and implementation. I would like to get back to work on these at some point as they may provide as both cautionary tales and critical guides in future constructions of ‘creative’ automata and machine performances, and to anyone engaged in the critical (reverse-)engineering of such entities and their constructions. (There are so many stories, (self-)reflective and (self-)critical, of shortcoming and failures that get lost in our need to tell tales of technocultural heroics.)

Meanwhile, in this post I’d like to provide a selective index of documentation of io 0.0.1 beta++, its construction and performance, both of material published on this site and elsewhere.

io 0.0.1 beta++ is an interactive, semiautonomous technological artifact that, in partnership with its human associates, performs a deliberately amplified staging of a socio-technical network—a network in which the primary protocol is improvisation. Together the cyborg ensemble explores the performance of identities, hybrids and relationships, and highlights the social agency of artifacts, and the social dimension of improvisation. Engineered by Han-earl Park, io 0.0.1 beta++ is a descendant, and significant re-construction, of his previous machine musicians, and it builds upon the work done with, and address some of the musical and practical problems of, these previous artifacts.

Standing as tall as a person, io 0.0.1 beta++ whimsically evokes a 1950s B-movie robot, constructed from ad-hoc components including plumbing, kitchenware and missile switches. It celebrates the material and corporeal; embracing the localized and embodied aspects of sociality, performance and improvisation.

Audio recordings

We watch and listen carefully because we know we’re seeing a kind of manifesto in action. What is an automaton? A sketch, a material characterization of the ideas the inventor and the inventor’s culture have about some aspect of life, and how it could be. io and its kind are alternate beings born of ideas, decisions and choices. It is because io stands alone, an automaton, that the performance recorded on this CD not only is music, but is about music.

Articles and publications

My article, ‘In Conversation with an Automaton: Identities and Agency in a Heterogeneous Social and Musical Network’ [local copy…], published in the Leonardo Electronic Almanac: ‘My Favorite Things: The Joy of the Gizmo’ (Volume 15, No. 11-12, November–December 2007) is still probably the best description of the motivations and choices behind the io enterprise.

Abstract

io 0.0.1 beta is an interactive, semi-autonomous technological artifact that, in partnership with its human associates, performs a deliberately amplified staging of a socio-technical network—a network in which primary protocol is improvisation. In this paper, I explore the performance of identities, hybrids and relationships, illustrating the space between myself (human partner and constructor) and io through imaginary conversations between us. Considering that io highlights, in particular, the social agency of artifacts, I find it fitting that my own notions about the nature of improvisation, the technical and the social have changed through my interactions with io.

Han-earl Park, ‘frankenmusic(s),’ November 25, 2008:

Fifteen days ago, during the break between beta test sessions, Franziska Schroeder asked a pithy question that cut to the core of this enterprise: what do I hope to achieve? My answer surprised me even as it reminded me of Sara’s observation: my goal with io (and io++) is to encapsulate my take on improvisation—its mechanisms, its sociality, its significance.

Franziska Schroeder, ‘io + I met,’ November 24, 2008:

Who is io? What does she sound like? How would she react to me? Would she respond? Would she challenge me (musically, that is). In other words, would she adopt sensitively to changes, make creative contributions and develop musical ideas suggested by me? [Read the rest…]

Almost eight years ago, when io-to-be was a bunch of discorporate code fragments, Sara Roberts remarked that the enterprise of constructing a machine improvisers wasn’t so much megalomanic as Frankensteinian.

Fifteen days ago, during the break between beta test sessions, Franziska Schroeder asked a pithy question that cut to the core of this enterprise: what do I hope to achieve? My answer surprised me even as it reminded me of Sara’s observation: my goal with io (and io++) is to encapsulate my take on improvisation—its mechanisms, its sociality, its significance. As I’ve written elsewhere,

improvisation is performance; it is an act; it is something you do. In order to make an artifact behave analogously to an improviser, I need to ascertain what might pass for, or what might function in the place of, improvisation. To venture into the construction of an improviser is to ask what is improvisation.

[read the whole thing…]

I’d anticipated that consulting with other improvisers with different backgrounds, practices and histories would be helpful to this construction, but I hadn’t guessed that it would bring into relief issues that lie at the kernel of this enterprise.

the techno-musical is political? personal?

This is the first time I’ve embodied the role of (techno-musical) project leader. That’s a problematic enough… but the interrogation and problematization of the technical construction was an interrogation and problematization of Han the constructor, improviser and, for lack of better word, theorist.

As I’ve stated elsewhere, I am reminded that this exploding—this interrogation and problematization—is how improvisers evolve, and the conditions under which practices and approaches mutate.

the machine that once could

In a sense io is stuck as a un-mutant improviser. It encapsulates what I though of improvisation seven years ago. Fine then; not now.

In my report to the Arts Council I wrote that

in exploring improvisation… and in the collision with other approaches and sensibilities, I have learned that this enterprise is ever-evolving as it adapts to new situations and contexts.

Although, io 0.0.1 beta++ as a funded project has a (bureaucratically necessary) end, perhaps it, as an entity, and as a focal point of practice and performance, is—road movie-like—a much more open ended enterprise.

Franziska Schroeder and io 0.0.1 beta++ (prototype) (Cork, March 26, 2009)

On the 10th of November 2008 I had the great pleasure to meet io.

She seemed a rather calm, clandestine creature, not saying much… not moving much, in fact not engaging with me much at all. However, she appeared to be a ‘saxophonistic’ persona—shiny, slightly shimmering in the sunlit surroundings.

But who is io? What does she sound like? How would she react to me? Would she respond? Would she challenge me (musically, that is). In other words, would she adopt sensitively to changes, make creative contributions and develop musical ideas suggested by me?

All sorts of questions went through my head before I even had played a note.
I was not told much about io in advance, in order to engage with her without any preconceptions.

I played and I listened…. io’s steady, breathy and rather regular sighs reminded me of a machinic engagement I had in 2000 when working on a piece entitled “Aquas Liberas.” That piece was based on recordings made in the Águas Livres Aqueduct, in Lisbon, Portugal. I had visited several machine rooms where water was pumped across pipes and the breathy machinic air sounds from the Lisbon site were reminiscent of io’s, at times, dis-engaged, de-contextualised replies.

I stopped. We talked. I played again and listened. I had found out a bit more about io and the next time I tried to ‘please’ her. I tried to soothe her into a calm, less hasty, more spacious musical dialogue. We engaged a little better.

I stopped. We talked. I played again. I wanted her to listen. This time she would need to be ‘with’ me. If the musical ideas dried up and we needed to stop she would need to listen. But she ignored me. The musical journey seemed to come to a halt (from my point of listening).

io carried on. I went along, trying to get her to conclude, to find a musical ending. io carried on. Why won’t she listen? Why won’t she acknowledge that we need to finish? io carried on. No surprises. No quest for anything new. No fresh ideas. No aspirations. No ending…

Improvisation, as George Lewis notes, shall become “not so much a practice, but an aspiration toward freedom…” …with io there is not yet in sight this “dangerous hybrid formed by agency and indeterminacy whose ultimate outcome is a continuous transformation of both Other and Self” (Lewis, 2007: Parallax, p.120).

io, we will meet again. I will transform you. You will transform me. Maybe.

• Greater variation in output.
  • Including pseudo-Braxtonian ‘separation’ implemented via interp tables.
  • Implementation of a meta-banalyzer that shakes up the system depending on input variation.
  • Greater variation in the VL70m settings.
• More responsive to external stimulus.
  • Implementation of a meta-banalyzer (see above).
  • Greater number of elements triggered by the banalyzers and the meta-banalyzer.
  • Fix error in the banalyzer+ class.
  • Variable event buffer.
  • Reduction in the damping and absorption parameters in the VL70m model.
• Less and more machine-esque.
  • Reduction in the damping and absorption variables in the VL70m model which results in a more ‘synthetic’ sound,
  • but also disguises the strongly cyclical generator.
