Hey Kassen and other Chuckists!
Hey Kassen and other Chuckists!
I  think it is interesting to note we used an alternative approach  considering the sync between Renato and me. The sound was generated by  Renato using ChucK/Vim/Jack and by me using ChucK/Emacs/Jack  without  sync. The audio from both of us was passed to a Pd patch  running on a  third computer operated by Gilson Beck, another composer,  part of the  trio (FooBarBaz). Gilson spatialized and mixed the audio  generated by  us with a visual interface: the movements of his hands were  tracked by a  "color tracker" implemented by Ricardo Fabbri on Pd/GEM  and the x/y  coordinates defined the panning effects. On this way we  could mix both  audio in certain times, creating a dialogue between my  sound, Renato's  sound and Gilson's.

I think Gilson can send you more details about his Pd patch and some videos about the human body interface tracked by colors.

Relembrando o experimento

Renato Fabbri por lists.cs.princeton.edu 28/11/11 para ChucK

This is what I used and it was quite enough given the execussion had another live coder and a PD and mixer improviser:

http://ubuntuone.com/7P9ZFMFVVa9cBr4LZ1xtjg

My replace map doesnt work though (last line of the text file on the link). Any idea? BTW, we live coded for more de 2 thousand people here in Brasil at Festival Contato. Some say about ~5 thousand, i guess ~3,5k. Chuck live-coding with Vim rvl3z. Vilson Vieira, the other live-coder, used Emacs. We projected both desktops at the same time.

cheers!,

Renato

Renato Fabbri 30/11/11 para ChucK

well, i wanted to do any documentation of what i did, so here it goes as it came. No sound, just a visual screenshot (perfect for reading as you hear some music of your preference :P) I did not see how it is and cant look that now. The mpeg files are running ok here, i am using mplayer in linux. But they did not run in Kaffeine and another player (dont reacall its name).

Dont know if they are uploaded right, i should put them on Vimeo. I would like to have my partners screens, but he had a problem with his lap. Vilson, where is the code u used to play with? all the best and cheers,

Thanks! I like that also. The idea is to use the desktop to play and make it more appealing. That bouncing white ball is 'processing'. The cow is 'cowsay'. Some years ago i did what i now call LDP (Linux Desktop Playing) with jack-rack, ardour, audacity, PD, chuck, python and even audacious. That was a really big mess, specially with ABT:

http://trac.assembla.com/audioexperiments/browser/ABeatDetector

Maybe what we are doing is live coding with heritances from LDP.

Anyway, these are the 5 small videos at Vimeo, so anyone can take a look: - live coding presentation, part 1 a basic principles of the live coding presentation we did on 20/11/2011 for about 3,5 thousand people on Festival CONTATO, São Carlos, Brazil. http://vimeo.com/33012735 - live coding presentation part1 b: REM and cows about Rapid Eyes Movement (REM) and use of cows in the live coding presentation we did on 20/11/2011 for about 3,5 thousand people on Festival CONTATO, São Carlos, Brazil. http://vimeo.com/33018740 - live coding presentation part2 improvisation improvisation part of the live coding presentation we did on 20/11/2011 for about 3,5 thousand people on Festival CONTATO, São Carlos, Brazil. http://vimeo.com/33019291 - presentation part3 soundscapes The part where we used soundscapes in the live coding presentation we did on 20/11/2011 for about 3,5 thousand people on Festival CONTATO, São Carlos, Brazil. http://vimeo.com/33025717 - presentation part4 improvisation2 ending endind of the live coding presentation we did on 20/11/2011 for about 3,5 thousand people on Festival CONTATO, São Carlos, Brazil. http://vimeo.com/33025913 cheers, rfabbri

Hey Kassen and other Chuckists! I think it is interesting to note we used an alternative approach considering the sync between Renato and me. The sound was generated by Renato using ChucK/Vim/Jack and by me using ChucK/Emacs/Jack without sync. The audio from both of us was passed to a Pd patch running on a third computer operated by Gilson Beck, another composer, part of the trio (FooBarBaz). Gilson spatialized and mixed the audio generated by us with a visual interface: the movements of his hands were tracked by a "color tracker" implemented by Ricardo Fabbri on Pd/GEM and the x/y coordinates defined the panning effects. On this way we could mix both audio in certain times, creating a dialogue between my sound, Renato's sound and Gilson's. Unfortunatelly I lost my laptop and all the codes within after the presentation, but I used a screen similar to Renato's recorded screencasts, using ChucK as a live sampler, similar to Thor's ixilang approach. A snippet of the code was saved here: https://gist.github.com/1379142 I think Gilson can send you more details about his Pd patch and some videos about the human body interface tracked by colors. All the best.
