Re: [PD] Pd & a lighting console
by William Grissom 07 Mar '05

07 Mar '05

Just to put this out there as an option, I have used a usb to dmx converter from colorkinetics to run their lights, and have written a pd extern to send rgb+channel commands to it, works very well in os x. the only downside is that it uses an cat5 cable to communicate to the lights, and i'm not sure how common that is among lighting manufacturers. peace Will

Don't know, I have only: holzi@holzi:/dev/input$ ls event0 event2 js0 js2 mice mouse1 mouse3 event1 event3 js1 js3 mouse0 mouse2 (event0 = touchpad, event1 = laptop keyboard, event2 and mouse1 = 1. additional mouse, event3 = sound, mouse2 = 2. additional mouse) So is there maybe an other way, to get more /dev/input/event* ? (Also I don't know where's the 2. keyboard? - It's at least nowhere in /dev/input/* !?) Thank you again, LG Georg -- SMS bei wichtigen e-mails und Ihre Gedanken sind frei ...

basic OS x install problems
by Gair Dunlop 06 Mar '05

06 Mar '05

Dear friends, I did have PD working but now it's not. An inspiring workshop with derek Holzer and Aymeric had me going with a quite interesting video mixer. however, after a serious crash, no luck. the interface appears for a fraction of a second then vanishes. I have tried a clearout and a re-install. in console i get the message dyld: /Applications/pure data/Pd-0.38-0test4HCS1.app/Contents/Resources/Scripts/../bin/pd can't open library: /sw/lib/libgsl.0.dylib (No such file or directory, errno = 2) How do I fix this? I am not a programmer by background. I have been struggling with this for ages and `am VERY frustrated. Is there anywhere a tutorial/online material on how to use console/terminal etc, and what the commands mean. sorry to appear stupid but it's the basics that need to be addressed in order to widen access... regards from G

unexpected behaviour of [symbol2list]
by Roman Haefeli 06 Mar '05

06 Mar '05

hi if you convert symbols, where the first character after the separator is a number, to a list, you get a list containing floats instead of symbols. this: [symbol 5hello-0034how-11are-you( | [symbol2list -] (from zexy) gives you: 5 34 11 you i would expect: list 5hello 0034how 11are you roman

Yeah, that is possible, you need to specify each mouse separately in /etc/X11/SF86Config-4. Then do this for the mouse that you want to use with X: InputDevice "Mouse2" "SendCoreEvents" You might also need to prevent X from getting all mouse events.

Segmented patch chords?
by James Aldridge 05 Mar '05

05 Mar '05

Is it possible to get segmented patch chords to work in Pd reminiscent of how Max handles them? A quick google search returned no results except a similar question.

Re: [PD] keyboard-interface (hid?)

Hallo! I have made now an array, where all the keys are stored in (but not automatic generated from /usr/include/linux/input.h - see attached file). Maybe this is not so good - but it works ... Some more (maybe stupid) linux specific questions: If I add an additional mouse (so it's now the 3. mouse if you also count the touchpad) this mouse is on my computer /dev/input/mouse2, but it's not in /dev/input/event* . So: 1) Is it also possible to access /dev/input/mouse2 with hid (because I didn't manage it ...) ? 2) This 3. mouse also influences the displayed mouse of the X - is it also possible to deactivate this mouse for X (so that it is only used within PD) ? Now for the keyboard: If I add a 2. keyboard I also don't get it in /dev/input/event* . I couldn't find it yet, where it is, but X knows the keyboard, so you can write with it. So again the same questions: 1) Is it possible to access this 2. keyboard somehow with hid? 2) And can I disable it for X again ?

PD/Audio in redhat or suse
by jmmmp 05 Mar '05

05 Mar '05

Hello, I have Redhat in my laptop (Thinkpad R51), but so far had - almost - only bad experiences. My teacher tried to install planet ccrma, jack and other of the more recent programs, but it is much harder as one expects (and he is an expert). I am seriously thinking about changing to suse, that besides it is much "nicer" in general, I know it is designed for my computer. I looked in the archives, but could find no satisfatory answer: would there be a reason not to do this change? (I don't mind building the programs, sometimes the rpms remind me of windows' automatic install) although it isn't possible to install ccrma in suse (?), there are also low-latency kernels, or other ways to get a satisfactory result with live-audio. (I have the rme pcmcia interface + multiface combo) Greetings, João Miguel Pais Lugostr. 14 79100 Freiburg i. Br. Deutschland +49 (0)761 7074997 jmmmp(a)arcor.de

Best PD-GEM Performance Computer ... + wiki
by Winfried Ritsch 05 Mar '05

05 Mar '05

Hi, We have to assemble one special PD/GEM Performance Computer and also I always got some questions about Computer best for PD performance. I Started a Wiki which discuss dedicated PD Computers (also embedded ones). If someone has made some special hardware and/or experiences, it would be nice it will be shown there... http://puredata.info/community/projects/pdcomputer/ My questions now: a) Quadro vs. geforce: If I want display on multiple large screens, (is there) what is the benefits of NVIDIA quadro cards to geforce (eg. 6800 SLI) on signal quality rendering benefits. ? Which feature are most important projecting on big screens ? b) If I do 4 projections on a big screen so they are merged to one picture, must the video be displayed in frame sync (maybe using more than one computer) from the beamer/videocard view (not the video frames as content). ? mfg winfried -- -- - ao.Univ.Prof. DI Winfried Ritsch - ritsch(a)iem.at - http://iem.at/ritsch - Institut fuer Elektronische Musik und Akustik - University of Music and Dramatic Art Graz - Tel. ++43-316-389-3510 (3170) Fax ++43-316-389-3171 - PGP-ID 69617A69 (see keyserver http://wwwkeys.at.gpg.net/) --
