Weavecoding performance experiments in Cornwall

Last week the weavecoding group met at Foam Kernow for our Cornish research gathering. As we approach the final stages of the project our discussions turn to publications, and which ideas from the start need revisiting. While they were here, I wanted to give local artists and researchers working with code and textiles a chance to meet Ellen, Emma and Alex. As we are a non-academic research organisation I wanted to avoid the normal powerpoint talks/coffee events and try something more informal and inclusive.

One of the original ideas we had was to combine weaving and coding in a performance setting, to both provide a way to make livecoding more inclusive with weaving, and at the same time to highlight the digital thought processes involved in weaving. Amber made vegetarian sushi for our audience and we set up the Jubilee Warehouse with a collection of experiments from the project:

  • The newly warped table loom with a live camera/projection from underneath the fabric as it was woven with codes for different weaves on post-it notes for people to try.
  • The tablet/inkle loom to represent ancient weaving techniques.
  • The pattern matrix tangible weavecoding machine and Raspberry Pi.
  • A brand new experiment by Francesca with a dancemat connected to the pattern matrix software for dance code weaving!
  • The slub livecoding setup.

This provided an opportunity for people to try things out and ask questions/provide discussion starting points. Our audience consisted of craft researchers, anthropological biologists, architects, game designers and technologists – so it all went on quite a lot longer than we anticipated! Alex and I provided some slub livecoded music to weave by, and my favourite part was the live weaving projection – with more projectors we could develop this combination of code and weaving performance more. Thanks to Emma for all the videos and photos!

London Algorave at nnnnn

In order to get ourselves prepared for the Dagstuhl livecoding seminar (more on that later), we kicked off with a London Algorave at nnnnn, Ryan Jordan’s noise research laboratory in deepest Hackney. Slub had one of our better performances, which was recorded – watch this space.

algoravin in the UK

A short trip around the UK for slub over the last couple of days, a livecoding gig in London at Bartlett Nexus in UCL at an event concerning architecture, games and hand made technology. A full video of the event (with us at the end) is here.

Then up to Birmingham to attend the Network Music Festival and do another performance late on Saturday night. While there we had a chance to meet the members of The Hub, pioneers of networked music and livecoding. It was inspiring to chat with such experienced musicians in this field. The NMF included a huge range of performances, for example Melatab who used Kinect cameras for networked performance in a shared virtual space. I’m planning some Kinect hacking soon, so I took some photos:

slub at /* vivo */

My last /* vivo */ Mexico post, some data from our livecoding performance on the final day. This was one of those performances where we had a rough plan and got a bit too carried away by the crowd to follow it (I guess one of the great things about improvisation!). Also to a great deal the music was influenced by mezcal, the fermented spirit from the maguey plant, which I can report is the secret ingredient of Mexican livecoding. My edit history and a screen shot of the final state of the program is online here. The new temporal recursion system was actually pretty damn challenging (hence the serious face) but in combination with Alex’s pattern generation seemed to get people moving pretty well…

Mexican livecoding style

At only around 2 years old, the Mexican livecoding scene is pretty advanced. Here are images of (I think) all of the performances at /*vivo*/ (Simposio Internacional de Música y Código 2012) in Mexico City, which included lots of processing, fluxus, pure data and ATMEL processor bithop along with supercollider and plenty of non-digital techniques too. The from-scratch technique is considered important in Mexico, with most performances using this creative restriction to great effect. My comments below are firmly biased in favour of fluxus, not considering myself knowledgeable enough for thorough examinations of supercollider usage. Also there are probably mistakes and misappropriations – let me know!

Hernani Villaseñor, Julio Zaldívar (M0M0) – A performance of contrasts between Julio’s C coded 8bit-shifting ATMEL sounds and Hernani’s from scratch supercollider scripts, both building up in intensity through the performance, a great opener. A side effect of Julio using avrdude to upload code resulted in the periodic sonification of bytecode as it spilled into the digital to analogue converter during uploads. He was also using an oscilloscope to visualise the sound output, some of the code clearly designed for their visuals as well as crunchy sounds.

Mitzi Olvera and Alejandro Franco – I’d been aware of Mitzi’s work for a while from her fluxus videos online so it was great to see this performance, she made good use of the fluxus immediate mode primitives, and started off with restricting them to points mode only, while building up a complex set of recursive patterns and switching render hints to break the performance down into distinct sections. She neatly transitioned from the initial hard lines and shapes all the way to softened transparent clouds. Meanwhile Alejandro built up the mix and blasted us with Karplus Strong synthesis, eventually forcing scserver to it’s knees by flooding it with silent events.

Julian Rohrhuber, Alberto de Campo – A good chunk of powerbooks unplugged (plugged in) from Julian and Alberto, starting with a short improvisation before switching to a full composition explored within the republic framework, sharing code and blending their identities.

Martín Zumaya (Stereo Vision), José Carlos Hasbun (joseCaos) – It was good to see Processing in use for livecoding, and Martin improvised a broad range of material until concentrating on iconic minimal constructions that matched well with José’s sounds – a steady build up of dark poly-rhythmic beats with some crazy feedback filtering mapped to the mouse coordinates to keep things fluid and unpredictable.

IOhannes Zmölnig – pure data morse code livecoded in Braille. This was an experiment based on his talk earlier that day, a study in making the code as hard to read for the performer as the audience. In fact the resulting effect was beautiful, ending with the self modification of position and structure that IOhannes is famous for – leaving a very consistent audio/visual link to the driving monotonic morse bass, bleeps and white noise.

Radiad3or (Jaime Lobato, Alberto Cerro, Fernando Lomelí, Iván Esquinca y Mauro Herrera) – part 1 was human instruction, analogue performance as well as a comment at the inadequacy of livecoding for a computer, with commands like “changeTimbre” for the performers to interpret using their voices, a drumkit, flutes and a didgeridoo. Following this, part 2 was about driving the computer with these sounds, inverting it into a position alongside or following the performers rather than a mediator, being reprogrammed by the music. This performance pushed the concept of livecoding to new levels, leaving us in the dust still coming to terms with what we were trying to do in the first place!

Benoît and the Mandelbrots (live from Karlsruhe) – a remote performance from Germany, the Mandelbrots dispatched layers upon layers of synthesised texture, along with their trademark in-performance text chat, a kind of code unto itself and a view into their collective mind. The time lag issues involved with remote streaming, not knowing what/when they could see of us, added an element to this performance all of it’s own. As did the surprise appearance of various troublemakers into the live video stream…

Jorge Ramírez – another remote performance, this time from Beijing, China. Part grimy glitch and part sonification of firewalls and effects of imagined or real monitoring and censorship algorithms this was powerful, and included more temporal disparity – this time caused by the sound arriving some time before the code that described it.

Si, si, si (Ernesto Romero Mariscal Guasp y Luciana Renner Maceralli) – a narrative combination of Luciana’s performance art, tiny webcam augmented theatre sets, and Ernesto’s supercollider soundtrack. Livecoding hasn’t ventured into storytelling much yet, and this performance indicated that it should. Luciana’s inventive use of projection with liquids and transparent fibres reminded me of the early days of film effects and was a counterpoint to Ernesto’s synthesised ambience and storytelling audio.

Luis Navarro, Emilio Ocelotl – ambitious stuff this – dark dubsteppy sounds from Emilio, driving parameters of a from-scratch fluxus sierpinski fractal exploration from Luis. Similar to Mitzi’s performance, Luis limited his scene to immediate mode primitives, a ternary tree recursion forming the basis for constantly morphing structures.

Alexandra Cárdenas, Eduardo Obieta – Something very exciting I noticed was a tendency when working in sound/visual pairs such as Alexandra and Eduardo for the sounds to be designed with the visuals in mind – e.g. the use of contrasting frequencies that could be picked out well by fft algorithms. This demonstrated a good mutual understanding, as well as a challenge to the normal DJ/VJ hierarchy. Eduardo fully exercised the NURBS primitive (I remember it would hardly render at 10fps when I first added it to fluxus!) exploding it to the sound input before unleashing the self-test script to end the performance in style!

Eduardo Meléndez – one of the original Mexican livecoders, programming audio and visuals at the same time! Not only that – but text (supercollider) and visual programming (vvvvv) in one performance too. I would have liked to have paid closer attention to this one, but I was a bit nervous

Slub finished off the performances, but I’ll write more about that soon as material comes in (I didn’t have time to take any photos!).

Cyclic score sketching for livecoding

Live coding in cyclic time, while making the process of sketching, painting and general mark making as much part of the musical performance as the coding is. This is a prototype for “The Hair of the Horse”, a performance with Alex McLean and Hester Reeve as part of Live Notation at the Arnofini on Friday 27th July. It’s incomplete without Alex’s code over projected and I’m also expecting the performance will consist of a much larger and messier score!
