Pure . Reactive . Music . Hack Day

july 18, 2009.

Over the weekend of july 11/12th a swarm of 'digital music hackers', brought together on the occasion of the London Music Hack Day, occupied the first floor of the brand new offices of the Guardian, just around the corner from King's Cross tube- and railway station, for a full 32 hours in-one-stretch.
For that is the idea of a Hack Day: gather a bunch of creative and energetic enthusiasts at some suitable place, provide them with free food, coffee, red bulls and beers, give them the tools they might need, lock them in for 24 hours, and then marvel at the brilliant things they come up with. Sort of a brainstorm, indeed, and increasingly popular especially - but not only - in the world of hi-tech and web-companies.

music hack

Envisioned and organized by James Darling and Soundcloud's Dave Haynes, London Music Hack Day, besides hosting workshops by RjDj, latter-day prophets of deferred form and inter/re/active music (... "huh!?" ... read on! ...), and the physical computing and interaction designers of Tinker.it, involved companies that make the streaming, selling and/or up-/downloading of digital music files their business (other than Soundcloud, there were 7digital, LastFM and peoplesmusicstore) and some that are focusing rather on the meta-side of music and its industries, like BBC Music, Gigulate. Or Songkick, striving - with the aid of concertgoers, who are asked to create their personal gigographies - to compile as complete as possible a database of this world's past and present live music events; and I suspect that were there other live music to be discovered in some distant galaxies, it'll eventually be included.

Songkick's basically an interesting project, as it might eventually assemble a unique collection of remembrances and memorabilia. If attendees of events indeed can be persuaded to massively upload their tickets and pictures, maybe sounds and vids, and write about their personal experience of the events, the little things that happened, who was there with them, etcetera. But for this to happen and become accessible there is a long way still to go. Just for fun, I tried to compile a short list of some of the concerts that I attended in the past, but the user interface that should allow one to do so is pretty awful, as is the current interface to the full gig directory, and I gave up after a couple of minutes. It evidently is a highly complex problem to put together such an historical index, and have some sort of ongoing check on the correctness of the data gathered, and I wonder whether Songkick's current approach is a viable one. It probably does a better job checking and tracking current and upcoming concerts, though, which seems to be what most people are using it for, as Songkick provides a location-based service for this.
It of course does come with loads of data, and combining data from varying sources into something that might turn out to be more than the sum of its parts was at the heart of what much of the Music Hack Day was about.

It was certainly no coincidence that it was the Guardian that so generously hosted this Hack Day event on its premises. This mayor UK daily's open platform and its Data blog, in which for free, public use are brought together all of the facts and figures that underlie its news coverage, were a seamless fit. It also underlines a growing awareness worldwide that, in the words of the paper's editor-in-chief Alan Rushbridger, "facts are sacred, and they belong to all of us".

Indeed, "the world is the totality of facts, not of things,", and though my recent ongoing citing of Wittgenstein maxims obviously and consciously borders on the tongue-in-cheek, there is no denying that there is no controlling your world without controlling - or at least being fully aware of - the manifold networks of its data.

Among the many 'music data mining and exploitation' possibilities presented I was most impressed by the potential of the music analysis and remix tools created and provided by the Echonest, which I would have loved to try my hands at, given the time that there was not. A description of Ben Smith's "BotTalk" hack might give you the idea, as well as an impression of what all that 'hacking' was about. Ben combined API's provided by LastFM and the Echonest to generate a mashup remix of tracks from a LastFM user's list of 'top artists'. The tracks, Ben explains on his code-page, were "sorted according to pitch and each track has a drum track created by taking the bars from the next track that match the key of the current track. Each track is then mixed with it's beat track, with the beat track looped; the resulting mix tracks are ordered by loudness and 30ish seconds of each are bolted together to create the final mix-tape".


ookoiIf you have followed the ookoi's doings over the past couple of years, you might suspect why these things fascinate us, and why - though being a mere goal-directed programmer, and a bender more than a hacker - I crossed the Channel to hang out at the London Guardian offices last weekend. Over the years data have become increasingly important in ookoi's work, as has the understanding that indeed the essence of our work does not lie within the creation of a series of fixed recordings (one after the other after the other after the ... ), but rather in the generation of a steadily evolving collection of sonic ingredients that may be combined, taken apart and re-combined in 'works/things' of which traditional recordings will provide merely snap-shots. Basically, they are 'continuously evolving'. Without proper beginning, nor actual end.

It is for this and related new and different notions of 'work' that recent evolving technologies (web application, video games, mobile devices ...) provide a 'natural' platform ( * ). Which in turn is the reason why for quite some time now already we have been researching the possibility of applying ookoi's work-philosophy to the (already no longer so very) new mobile devices, and e.g. develop some ookoi iPhone things.


rjdjRjDj is certainly among the most interesting of the currently available 'iPhone music things'. If you are somewhat familiar with dsp, you will grasp what I mean when I say that at heart the RjDj app, via a library of 'abstractions', provides you with the necessary ins and outs to execute PD-patches on your iPhone, and access some of the iThing's typical features, like, most prominently, the microphone and the accelerometer.
A such patch RjDj calls a scene. The application is nothing more (nor less) than a player for the scenes. The scenes are the 'songs'. And if you know how to make a PD-patch, you know how to hack an RjDj-scene.
So, that what you are 'playing' in general will not be finished sound/music recordings, but - more or less open and inter/re/active - sound/music generating processes ...

I remember a footnote in Paul Hegarty's (somewhat tedious) history of noise/music book ( ** ) that - and I think he is right - denounces laptop music performances as being "not enough of an anti-spectacle". One should, he writes, "remove the laptop performer altogether". Putting it with just a bit of hyperbole, RjDj allows you to do exactly that: get rid of the laptop performer by downloading h(er)(is) patch as a scene, to listen to and play around with.
That is one of RjDj's potentials. Maybe it is just a minor one.

The second is the one put to the fore by RjDj's creators. It is a fine buzzphrase as well: reactive music.


RjDj-makers (fltr) Florian Waldner, Frank Barknecht and RjDj-founder Michael Breidenbruecker, tuesday july 14th, atop of their brand new London office, just off Clerkenwell Road, where we took some air and sun.

I only enjoy walking around with earplugs listening to sounds on a walkman or pod-like device for an extended period of time when actually, in one way or another, the real-world soundscape around me continues to be involved. This for instance is the case when one monitors incoming sounds on a recording device while field recording the city or elsewhere, simply because listening through headphones comes with a rather drastic transformation of the sonic picture that one is receiving: it's a different world that you listen to in stereo; some say it's even better in mono ... ;-) . It is also something that I found to occur when a couple of years ago I went around Paris with my ears plugged to the quietish ambient loops of FM3's Buddha Machine, which added an interesting 'inside' layer to the sounds from the 'outside'. This experience I recalled some time after, in december 2006, when reporting on Noah Vawter's Ambient Addition project. Noah constructed a walkman-like device, which had binaural microphones built into a set of headphones, and used a dsp chip to analyze the environmental sounds and, applying a certain number of algorithms and transformations, musicalize them.

While at the time Noah had to custom built his 'reactive walkman', RjDj includes such principles of 'ambient addition' (or, as I'd rather call it: 'ambient transformation') in the reactive music that it proposes to bring to your mobile devices by means of its scenes. Many of these - like the app's primordial Echolon scene - use the microphone and in real time apply a certain number of effects to the environmental sounds thus taken in. (For those that are wondering, the 'R' stands for 'Reality'.)

Of course it has been possible for a long time already for artists to present and distribute their works as an inter/re/active application. But until recently almost always this implied the cumbersome process of launching a standalone application from a CDrom or DVD, or some webapp at a dedicated URL, which appears in the end to be a huge no no for other than merely incidental use. ( *** )
Besides its mobility, the fact that a platform like RjDj's for the playing of interactive sound/music scenes asks for manipulations that are not different from those necessary for launching a track or playlist in an mp3 player, makes all the difference.

I remember a discussion on interactivity in relation to music which lead me to conclude that, all said and done, 'interactive music' is just a fancy way of saying: 'instrument'. RjDj reflects this fact, by having all of its scenes come with the option to record all that one is listening to.
Absolutely right.
It also follows that each listener will get the music she or he deserves: though it remains possible to passively listen also to such modular inter/re/active music, the listener is encouraged to participate in the creation of the auditive experience other than 'merely' by giving it his or her attention. That participation and the corresponding acquisition of a certain skill (practice) in playing a scene, like in playing a game, does prove to be rewarding.

One need not be a visionary to predict that mobile applications will become a major channel for the distribution of music (and of content in general). Such applications will allow musicians to present and give access to their music in ways that go far beyond the mere set of fixed sound recordings on a CDs or as a collection of downloadable digital files. rjdj hackday
For some time already with the ookoi we have been researching the possibility of presenting our soundtrack for Winterland as an interactive iPhone application. We indeed went through the somewhat cumbersome procedure of officially enrolling as 'iPhone developers' with Apple, played around with the DK, learned a bit of Objective-C, read manuals and tutorials and met up for drinks with pro-programmers ("Hi Daniel!" ;-) ...).
Also our interest in RjDj's approach stems from this initial motivation. Which, actually, on the way, broadened up, and meanwhile has given rise to a whole series of ideas and what we'd like to-do's.

RjDj now, after many years, finally provided us with a valid excuse to learn PD and begin to compose PD patches.

It was with some of the ookoi's first home-brewed PD-patches, a lot of questions but also more or less clear ideas on what iPhone inter/re/activity we wanted to add to them, that I came to RjDj's workshop at the Music Hack Day.

I am happy to say that I went to the right place. It was fun. It was instructive. It was productive.
With the help of Florian Waldner and Frank Barknecht, early sunday afternoon a test-version of ookoi's ShakeNRoll was up and running on my iPhone.


Pure image.
Pure sound.

Pure data.

That makes sense.

(*) Formerly a composer might have fantasized about creating an audiowork that will be played continuously, 24/7, and evolve over time; it is through the technology of e.g. audio streaming servers that this becomes a 'natural' format, no less available for use than that of a CD recording or an hour-long concert performance.
