Gallery NANO invites all with interested in sharing, exchanging and working together. Focus is to create a loop activity where people would exchange parts of their creative visions. Moderators will support the whole process with creating and sharing PD patches for audio and visual collaborative real time performing. Program: day time will be spend in short presentations of 5 minutes where each participant can explain ideas, development or share visions about specific project. Second part of the day will be spend in swapping parts of the code so people can try out other peoples patches, change them, reshape and transform them. This process will help us in creating a group work. During evenings a place for collaborative performances in video and sound will be staged with all participants who show interest. Collaboration is a focus, there will be no individual works but all individual works will be fused in one. Gallery NANO opened its doors for unusual non-exhibition event that focuses on active participation. Interaction goes on a level where gallery visitors not only interact with artwork, but are creating artwork together with artist. This artwork is in constant change and work is in constant progress. PD Exchange Summit (PES) is based on ideas of Free Culture, where collaboration and cooperation is overcoming individual representational artistic work into group works. Workday: 10:30 - 11 individual introductions 11 - 13, 14 - 17 group work 20 - 21 exhibiting/performing the days work Idea and organization: Kruno Jo??t, Zagreb; Guests: Guy van Belle, OKNO.be Belgium, Lenka Dolanova, YO-YO, Czechand Michal Kinderny, YO-YO, Czech; Gallery NANO curator: Martina Mezak. http://gentlejunk.net/art01 http://www.artenativa.hr/ARTMETAMEDIA.htm _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Hello, Date: Sunday, 27 June, 2010 - 13:00 We'll focus on video and 3D : Jack from the RYBN collective (http://rybn.org) will come over to introduce us to GEM, one of the graphical libraries in PD, focussing on video and 3D generative synthesis. The goal is to create a thorough understanding of these techniques over a few sessions. Sessions from 14h till 18h, at OKNO. As usual, these are free events, come with your laptop, headphones and motivations/projects. Please send a short e-mail to ol(a)okno.be to confirm your participation, so we can prepare properly. ++ Jack _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

dmx and pd
by Nick Burge 19 Jun '10

19 Jun '10

I would like to use pd to control some lights via a wii device. I am on linux 10.04. I have the wii up and running in pd, I have compiled dmx512 from the iem repository, and have the objects dmxin and dmx out in my pd/extra directory. Since these objects depend upon dmx4linux I tried to compile the dmx4linux programme which is supposed to create a dev/dmx directory...... but so far it does'nt do so. The latest version goes back to 2008, so it may not be viable with Lucid.?? Typing dmesg i see my dmx usb pro interface is recognised as dev/ttyUSB0 when i plug it in. But the pd objects will not create. Does anyone on the list have a viable dmx system (preferably using enttec dmx usb pro) set up on linux that they could inform me about? Thanks. Nick.

weighted average (or ?)
by João Pais 19 Jun '10

19 Jun '10

Hi, I was going to program something, but wanted to see if someone hasn't done it before. I needed a "weighted average" (probably the name is incorrect, I just made it up), that is: considering an x number of sliders going from 0 to 1, the sum of all sliders would be always 1. In case I drag one slider up or down, the difference in value to the total (1) would be distributed through the other sliders that aren't active. That itself isn't that hard to do, but then harder would be to consider the previous state when the next change happens. So that a slider that is already higher than the others by the next change would "retain" the average countour. I'll give an example for clarity: - 4 sliders, initial state is each at 0,25 (4x0,25 = 1) - I move slider #2 to 0,4, leaving a remainer of 0,6 to be distributed by the other sliders. Sliders #1, #3 and #4 would then go down to 0,2 each. - now slider #2 is higher than the others. But if I move #4 to 0,4, it shouldn't happen that #1-3 move to 0,2. instead, the higher countour of #2 should be taken into account. The end result would be something like #4 = 0,4, #2 > 0,2, and #1 & #3 < 0,2. - if I continued moving the sliders around, a similar behaviour would happen. - as a bonus, it would be possible to lock a slider into the present value, only the others move. Is there any external/patch for this, or any statistic formula / website I should look at for this?

triggering fx
by Marco Donnarumma 19 Jun '10

19 Jun '10

Hi, you might be interested in C::NTR::L http://cntrl.sourceforge.net. It's a Pd-based application which recognizes pitch out of an electric bass guitar, guitar, or piano (only two octaves) and trigger audiovisual fx (outputting a bang everytime a new note is recognized using a proper threshold system to avoid weird behaviour). You can also set manually the frequencies you want to track. I use it often in my performances. If you need help while using/de-constructing it, just drop me a line, I'll be glad to help you.
