is there a way to take the [adc~] object... take the signal that's coming in, and then somehow make it cancel out when it reaches the mic... so there's no feedback.. not really sure of how this would work... thanks, Robert

hi here's the news from enttec: DMX USB Pro Interface Features: • Micro processor enabled • 1500 V isolation (protect your computer from surges) • 1 Input & 1 Output connector (there is only one DMX port though) • Fully compatible with RDM • Internal frame buffering (will work on any PC) • Will talk at any comm's speed, so it will be completely compatible with any system for which the FTDI chip has drivers (Windows, OSX, Linux..) • Universe & user config EEPROM • simple API to: update DMX buffers, read incoming DMX, configure refresh rates ... http://www.enttec.com/dmxusb_pro.php so olaf, can you do something for us as osx will be ok with this interface... dank-e nicolas

Pismo/Quattro/PD endian-ness?
by vze26m98 18 Mar '05

18 Mar '05

Hi all- I have PD 0.38-4 from Miller's site running on my Mac Pismo under Debian Linux 2.6.8. I've got an M-Audio Quattro attached, which seems to do pretty well with respect to data rates and channels using aplay. Here's my issue with PD: I can run it using OSS emulation and PD will let me switch from Pismo internal audio to the Quattro. If I enable ALSA, I can use the Pismo internal audio, but when I switch to the Quattro box, I'm getting some wild sounds... >From what it sounds like, I think there's an endian problem as the Pismo is big- and the Quattro is little-endian. I'm getting a "snd_pcm_hw_params_set_format: Invalid argument" response at the terminal, not in the PD message box. Anyone have any thoughts or pointers? I'll of course start to look at the source, but any past wisdom would be greatly appreciated. Best and thanks, Tad Turner <vze26m98(a)optonline.net>

PMPD Editor version 0.001gamma
by Frank Barknecht 18 Mar '05

18 Mar '05

Hi, I reworked the pmpd-editor I mentioned before a bit, also using Nicolas' work as inspiration. It's attached and already a bit fun. To use it, open both structures.pd and pmpd-editor.pd [pd HELP] contains an introduction on how to use it, in case of questions, just shoot. The links are still a bit off position, but well, it's a start. Ciao -- Frank Barknecht _ ______footils.org__ _ __latest track: "scans" _ http://footils.org/cms/show/41

video tracking how advanced?
by Chris O'Shea 18 Mar '05

18 Mar '05

I am currently on Windows and have spent quite a long time learning Eyesweb and it is a fab program. My problem is that I would like to move completely to Linux, and they haven't made Eyesweb for Linux (annoying). I've not tried video tracking in PD / GEM / PiDiP yet, and wondered if anyone could tell me how much can be done? I am looking to do pattern tracking, i.e. track multiple objects that look the same. In Eyesweb this is called posture recognition. cv.jit for Jitter can do this as well. I have just seen pdp_shape on the PiDiP website, which might be able to do the job. Can it track and identify blobs though? (computer tracking gurus will know what i mean) Any advice in this area would be great thanks, -- ~ Chris O'Shea; # +44(0)7974 96871; # me-at-chrisoshea.org; # www.chrisoshea.org;

pd on shared linux server
by cera 18 Mar '05

18 Mar '05

hi all, i'm new to this list (and pd) so i thought i'd introduce myself & throw out some general (and more specific) questions i've got... i've been working with max/msp for the past few years, and i've always been curious to check out pd, but haven't had the occasion (or else i'm just lazy ;) basically what has motivated me to take the plunge is an interest in creating a series of patches that will stream audio from a linux server based on user interactivity on a website like i said i'm new to this game, so any hints you all can give me would be great i'm thinking basically i'd use the xml socket library in flash with osc as the glue between flash & pd i've downloaded pd for os x & started going through the documentation, so hopefully i'll be up & running fairly quickly on that end of things in the meantime i'm trying to figure out how to get some sort of a testing environment up on the server as well i got this far in the pd installation process & hit a wall: checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for a BSD-compatible install... /usr/bin/install -c checking whether make sets $(MAKE)... yes checking how to run the C preprocessor... gcc -E checking for an ANSI C-conforming const... yes checking for egrep... grep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking for pid_t... yes checking for size_t... yes checking whether time.h and sys/time.h may both be included... yes checking for ANSI C header files... (cached) yes checking fcntl.h usability... yes checking fcntl.h presence... yes checking for fcntl.h... yes checking limits.h usability... yes checking limits.h presence... yes checking for limits.h... yes checking malloc.h usability... yes checking malloc.h presence... yes checking for malloc.h... yes checking sys/ioctl.h usability... yes checking sys/ioctl.h presence... yes checking for sys/ioctl.h... yes checking sys/time.h usability... yes checking sys/time.h presence... yes checking for sys/time.h... yes checking for unistd.h... (cached) yes checking bstring.h usability... no checking bstring.h presence... no checking for bstring.h... no checking whether gcc needs -traditional... no checking return type of signal handlers... void checking for vprintf... yes checking for _doprnt... no checking for gettimeofday... yes checking for select... yes checking for socket... yes checking for strerror... yes checking for dlopen in -ldl... yes checking for sin in -lffm... no checking for sin in -lm... yes checking for pthread_create in -lpthread... yes checking for X... no checking for XCreateWindow in -lX11... no no X11 found checking tcl.h usability... no checking tcl.h presence... no checking for tcl.h... no checking tcl8.7/tcl.h usability... no checking tcl8.7/tcl.h presence... no checking for tcl8.7/tcl.h... no checking tcl8.6/tcl.h usability... no checking tcl8.6/tcl.h presence... no checking for tcl8.6/tcl.h... no checking tcl8.5/tcl.h usability... no checking tcl8.5/tcl.h presence... no checking for tcl8.5/tcl.h... no checking tcl8.4/tcl.h usability... no checking tcl8.4/tcl.h presence... no checking for tcl8.4/tcl.h... no checking tcl8.3/tcl.h usability... no checking tcl8.3/tcl.h presence... no checking for tcl8.3/tcl.h... no checking tcl8.2/tcl.h usability... no checking tcl8.2/tcl.h presence... no checking for tcl8.2/tcl.h... no no tcl header found so, from what i can tell, it looks like i need to install x86 as mentioned in the pd documentation unfortunately i'm using a virtual private server, so i don't have root the Xinstall.sh file told me: Checking which OS you're running... uname reports 'Linux' version '2.4.9-e.40', architecture 'i686'. libc version is '6.2.4' (6.2). Binary distribution name is 'Linux-ix86-glibc22' so i downloaded everything i needed according to the info at http://ftp.xfree86.org/pub/XFree86/4.4.0/binaries/Install then when i ran it again, i got: sh: ./Xinstall.sh: bad interpreter: Permission denied i then tried chmod'ing & chown'ing everything to my account, but keep getting the same error message so i'm not sure where that leaves me... i see that there are compiled versions of pd for mac, irix & windows... but is there one for linux anywhere? i'm also curious as how i would connect the audio output from a pd patch to a streaming mechanism and whether this is something that is even feasible in a shared environment, or if i would need to have a dedicated machine co-located somewhere any help or guidance anyone out there could give me would be great... thanks, -mark

Mac OS X installer with library documentation
by Burt 18 Mar '05

18 Mar '05

Greetings list, First of all I want to thank Hans again for the great work he has done with providing an easy-to-install Pure Data extended application for OS X. However, I was having a few problems with his latest installer (Pd-0.38-0test4HCS1.dmg). 1. Running OS X 10.3.8, I couldn't get zexy, Gem, pmpd, or vasp to load via the Preferences>Startup menu. In fact, it crashed when I tried to load them that way, and I wound up having to write a Launcher script. (That was my solution at the time). 2. Some of the documentation (especially pdp or pddp) would crash PD in OS X because I haven't gotten them to run correctly. 3. Not all of the documentation for the extra libraries is easy to use for most users. So, I took Miller Puckette's distribution and copied the extra libraries from Hans' version and placed them in a directory structure that made sense to me. Then I edited the Pd.tk script to add an extra menu for Gem and some submenus in the Help menu for the extra libraries. This was somewhat difficult for me, because I have rather limited experience as a programmer/scripter. I have placed my new Pd 0.38.3 OS X application on the web. I would appreciate any feedback anyone has, especially about my changes to the Pd.tk script in bin. I have documented all my changes so they should be easy to find. If anything I have done goes against normal PD programming protocol or structuring, definitely let me know. Samuel Burt
