Sound to light for light to sound

xynaaxmue
xynaaxmue

I collaborated with xname on a performance as xynaaxmue on Saturday, audio+video up soon I hope.. xname performs with circuits that turn light into sound, improvising noise using stroboscopic lights. I was live coding with tidalcycles, as ever.

In the past I’ve created flashing patterns on an external monitor for xname’s circuits to feed off, check here for a recording of that one. This time I wanted to control a pair of RGB flash panels over DMX.. I used a tinkerit DMX hat for the arduino, officially retired but you can still find them online and the library is downloadable on github.

I hacked together a Tidal interface the night + morning before the conference, and it worked pretty well.. The Haskell and Arduino code is here.

With everything loaded up, Tidal code like this triggers flashes of light as well as sound:

x2 $ every 2 (slow 2) $ (jux (rev) $ foldEvery [5,7] (slow 2) 
   $ (slowspread (chop) [64,128,32] 
   $ sound "bd*2 [arpy:2 arpy] [mt claus*3] [voodoo ind]"))
  # dur "0.02"
  # nudge (slow 4 sine1)

The basic features:
  • sound – (sample name) is translated into colour in a semi-arbitrary way (a mapping which falls back on some crypto hashing)
  • pan – (kind of) pans between the two lights
  • dur – controls the duration of the flash
  • the flashes have a linear fade, which works across chop and striate
  • it is kind of polyphonic but the colour mixing can be improved.. mixing coloured light seems to get into the realm of philosophy though !

Will update with documentation of the performance itself when it’s up.

Project stock check

Not much time to reflect right now, but taking some time to think about ongoing and upcoming activities at least..

Making Spicule LP is going pretty well, the crowdfund is past the halfway mark, the graphic and hardware design coming together with ace collaborators I’m hardly worthy of working with, and I’m looking forward to spending a lot more time in my studio over the summer.

My Open Data Institute sound art residency isn’t going too badly either, I’ve been working on an exhibition there called Thinking Out Loud with curator in residence Hannah Redler which opens soon. It’ll include great work by Felicity Ford, David Griffiths and Julian Rohrhuber, Ellen Harlizius-Klück, Dan Hett, David Littler, Antonio Roberts, Sam Meech, and Amy Twigger-Holroyd, and a ‘looking screen’ where I’ll be able to make my activities during the residency public, as I move from a research phase to making some strange things. I’ve also brought my 2002 “forkbomb.pl” software artwork out of retirement.

A few writing projects wrapping up – the Oxford Handbook on Algorithmic Music coming out of its formal review stage, a special issue of Textile journal coming together, polishing off an article in a special issue of Contemporary Theatre review with Kate Sicchio about our Sound Choreographer <> Body Code collaboration (deadline tonight, erp).. Plus a collaborative book project on live coding emerging nicely.

Quite a few events coming up, including organising an euleroom event, an Algorave tent at EMFCamp, and looming on the horizon — a new festival on Algorithmic and Mechanical Movement (AlgoMech for short) in November. AlgoMech will be a big focus really, but I’m on the way I’m looking forward to some collaborative performances, an audio/visual noise performance with xname (interleaved as xynaaxmue) at the third iteration of Live Interfaces, and a performance at computer club in Sheffield with Alexandra Cardenas. Hoping to play again with Matthew Yee-King as Canute soon, and maybe Slub will burst out on the scene again as well.

I’m also finding more time to contribute to TidalCycles, which is starting to feel like a proper free/open source project now, with quite a few exciting developments and side-projects spinning off it.

I’ve had a great time there, but am wrapping up my research and teaching work in the University of Leeds, just a spot of supervision to do now and I’m done. All being well, I’ll be joining a new five-year project in a research institution, starting in a couple of months time, lead by Ellen Harlizius-Klück and working also with FoAM Kernow.

That’s about it I think.. It seems like a lot, but it actually feels like everything is coming together and becoming easier to think about.. Especially the AlgoMech festival which brings together just about everything I’ve been doing and interested in since.. forever, really.. and can’t wait to get stuck into a new strand of research.

Anticipation video

Here’s a video from sonic pattern last year, working with Alex Keegan on a two-date project playing with beat perception in dance music that I wrote about here. This collaboration was brought together by Nick Hughes, they are both part of the ace agrobeat band Blood Sport. This was a really nice experiment, hoping to work with them more this year.

At last

A quick algorave track for you:

Cycle 24 extended

Another quick cyclic extension,

it’s the weather for dnb

Algorithmic Yorkshire

My new year’s resolution was not to start any new collaborations.

Here’s a new collaboration with Ash Sagar aka section_9 (among others):

First live date is at the Newcastle Gateshead Algorave on the 26th April. Judging by this first jam session it should be a blinder..

Cycle 22 live extension

Here’s a new work in progress, I am happy with how things are going with Tidal at the moment

(redone, less quiet..)

Here’s Broken, a new two-sided single out on Chordpunch.
