Re: [PD] looking for open dmx external
by David Kirkpatrick 08 Oct '08

08 Oct '08

Hi Peter, The Open DMX has stability problems and the fading is jolty sometimes. Something to do with not being able to store an entire DMX frame at the same time I think. I read an article a while ago that explained the exact differences, but I can't seem to find it again. I have had no issues with the Pro at all. So definitely go with the Pro if you can. It isn't that much more expensive anyway, and it just doesn't break.

He made it specifically for a Windows based theatre work I was doing. [dmxsend] is also designed to work with the Enttec DMX USB Pro, not the Enttec Open DMX. The two devices work quite differently. David, do you know in what respect they differ? Which one is better? Peter _________________________________________________________________

looking for a Workshop person - Arduino, etc
by Tim Boykett 07 Oct '08

07 Oct '08

Hi PDers, a friend from the local arts university student union has asked me whether I know of someone who could do a workshop on the Arduino and using it with Max and/or PD. The workshop should happen this semester (up to Feb 2009) for two days or so. The Uni is in Linz, Austria. There is some money for it. This might work well for a travelling musician or artist who is close by, or someone from Czech Rep. or Austria needing a side job. I would find it interesting to also offer them a PD workshop or something similar, perhaps PDP or Gridflow or whatever other bits are cool and sexy this time of the year. It would be good to be biligual (German and English). Either contact me or Jakob at jakob(a)bunostik.org for further details. Cheers, tim

[route 0] seems to match all symbol type messages
by Roman Haefeli 07 Oct '08

07 Oct '08

hi all is this expected behaviour due to some unexpected reason or is it simply a bug? [route 0] seems to match all symbol type messages, but not anything nor list messages (of course: if the first element of the list is '0', it matches). roman ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de

tanh approximation
by Andy Farnell 07 Oct '08

07 Oct '08

Hi all, An approximation to tanh(x) is a continued fraction x/1+ (x^2)/3+ (4x^2)/5+ (16x^2)/9+ ... See attached. I got it working, but by trial and error needed to scale the domain by 1/pi and add some weird scale to the range. I'm confused about where these numbers come from. Can anyone explain this please? cheers, Andy -- Use the source

6 speakers in a circle, ambi? vbap?
by Hans-Christoph Steiner 06 Oct '08

06 Oct '08

So I am working on sound for a permanent installation involving 6 speakers in a large circular room. Are 6 speakers enough to do anything useful using ambisonics? Or am I better off using the simpler vbap? I am just starting to understand the basics of ambisonics, thanks to Florian's intro. I will be programmatically controlling the position of the samples, since it will be synced up with a video. So I don't think I really need the GUIs like cubemixer. Are there any simple, working demos of the IEM ambi stuff? .hc ------------------------------------------------------------------------ ---- I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality and freedom for their spirits. - Martin Luther King, Jr.

Also, I do prefer using hash -r because I don't need to restart xserver after uninstalling with this command line, and it can be added to the build system. yo

Re: [PD] [wiimote] and inf
by Hans-Christoph Steiner 05 Oct '08

05 Oct '08

I am talking about [wiimote], which is the exact object name for Mike Woz's GNU/Linux+libcwiid objectclass: http://mikewoz.com/index.php?page=pd-stuff Pix just did a ton of work on that wiimote, hopefully he'll be submitting a patch soon. It was used in a Medialab Prado AVLAB project, W_space, where they used 5 wiiremotes to track the whole body. As far as I know, this is the only software out there that can now reliably get information from 5 wiiremotes at once. .hc On Oct 5, 2008, at 3:58 PM, Yvan Vander Sanden wrote: > Which [wiimote] are we talking about?

Re: [PD] Gem pix and PDP failure - tatiana works with many errors.
by Mark Pasquesi 05 Oct '08

05 Oct '08

Hey all, Here are the missing patches. Hope someone has an idea. They are: I) a minimac dualcore using OSX10.4.11, Ubuntu710, and Dynebolic. II) an HP omnibook using dynebolic and ubuntu710 III) a titanium g4 using os x.3.9, x.4.11 Trouble with gem and pdp on all three computers. Trouble with gridflow on Dynebolic. The problems are video related. I used kino on Ubuntu and Dyne as a test. Quicktime on mac. I have mpeg streamclip and ffmpeg functioning on all mac builds (except os9). Imagemagick is also functioning. Thinking it might be permissions, I gave full user permissions for video on Ubuntu710. This resolved Kino's issues on the HP. Other method was booting from root, which always corrected Kinos camera access problem. Also successful for Kino on Ubuntu. Is this an issue on PD. Macintel: 1) Dyne PD and gridflow worked well enough when booting from a Ubuntu 704 nest. This ubuntu also works fine with PD, gem, pdp. However, on the 710 nest, Dyne's pd and gridflow do not work - even though it is the same version of Dyne...with the same puredyne libraries. 2) Ubuntu 710 PD gem and pdp do not function well. Especially live cam. 3) The os10.4.11 install output is seen below, as is the kernel crash. The gem pix example is attached, as is the videoo mixer patch, as is the tatiana example. Only tatiana functions stably, working well with live remixes. However, lots of errors are reported, though it functions. --- On Tue, 9/30/08, Mark Pasquesi <mjsqueeze(a)yahoo.com> wrote: From: Mark Pasquesi <mjsqueeze(a)yahoo.com> Subject: Gem pix and PDP failure - tatiana works with many errors.

Tell me if this might be related.... Ubuntu live video access - kino and PD tests.. on my Omnibook XE3: The issue is clearly permissions. On Ubuntu xen 710, default does not allow video use without root. If we are cross programming, might there be permission errors?? (I did give my user video access, which fixed Kino access - but not PD!) If it is permissions, Where are PD's hardware permissions given? How can we load with access by default on Ubuntu and Dyne:bolic? Thus kino, when not launched as root, will not access video on the Ubuntu box. I just ran a test with Kino - terminal boot as root resolved this. Here's the results from kino boot from gui - warning: raw1394 kernel module not loaded or failure read/write dev/raw1394. Could this also be a problem with pd-extended access? How can we change this permission without breaking ubuntu 'standards'. (I changed permissions recursively last week on Ubuntu and caused panics that forced me to reinstall completely.....) I have found contradictory advice, and confusing boot script proposals that have also resulted in less than ideal results... No interface, terminal only Ubuntu - Fun, in other words. I imagine this is the same problem I had on the embedded Dyn:bolic pd and Kino. Both did not function on 710 (OmnibookXE3 and minimac), both functioned on the Ubuntu 704 minimac build, (first time I saw gridflow function!!! On dynebolic - lovely!!!) However, I have to ask at what point Dynebolic is dependent on its host system...Why can't it function even when Ubuntu 710 does not??? Since on the minimac, I had no such problem on the 7.04 Ubuntu and its embedded dyne:bolic. So are these permissions demands a result of an overzealous response by Ubuntu to their former security weaknesses...?? Sorry this is so Long. Hope it's clear. MArk
