hi

I would like to be able to distinguish between mono and stereo files at
loading time. I am loading the sound with soundfiler using this messages
which works both for stereo and mono files

read -resize path_to_file table1 table2

any suggestions? maybe there is some way to check if the second table is

Re: [PD] pix_film and readsf not in sync....

[altern]

we had three different videos 4 to 6 mins length. Format was mpeg
video, and the audio was standard 44100 16 bits. The video rate was
29.97 and yes I think this was the problem

I finally solved it using line to ramp the number of frames+1 in the
time duration of the video. Unfortunately my solution came too late to
use it in the exhibition, and I did not have wireless connection at
the place I was so I could not read this until today, that would have
solved lot of trouble and stress ... thanks anyway,

[PD] pix_film and readsf not in sync....

[altern]

hi

I am reading a video with pix_film and trigger it using auto, at the
same time load a sound file with readsf ~ . This is ok for a while but
after some time they go out of sync. The sound goes faster than the
video.

Any simple solution to this? or do I need to construct my own system
to play the video passing the frame number to the pix_film? maybe
using a line object with the total num of frames and the total time
length of the video ...

thanks

I decided write the list because I also started to think that this
mixing was "hardwired" in the card.  I tested the sound blaster under
linux and windows and it does exactly the same thing in both systems.
I played around with all options in the windows sound blaster control
panel and got all kinds of weird surround effects but no way to
deactivate it.

I have a 12 euros unbranded 7.1 sound card that allows to do exactly
what I am after but this is not mine so it cannot be used for a two
months long installation. So I will visit few shops later and try to
get some cards I can test.

thanks!

[PD] six sound outputs with sound blaster X-Fi Surround 5.1

[altern]

hi

I am trying to get this sound blaster X-Fi Surround 5.1 sound card to
work on windows with 6 outputs

http://www.google.com/search?q=Creative+Soundblaster+X-Fi+Surround+5.1&hl=eu&client=ubuntu&hs=Mvz&channel=fs&prmd=imvns&tbm=isch&tbo=u&source=univ&sa=X&ei=NxxVT_XdNYXF0QXTwvnXCw&ved=0CB4QsAQ&biw=1024&bih=699

The idea is to get a

adc~ 1 2 3 4 5 6

and route different sounds to each of the outputs that connects to
self powered mono speakers.

But I am going nuts. The card only works with 2 outputs under ASIO.
And with the default configuration if I set 6 outputs it does some
kind of 5.1 mixing. I have tried to disable all 5.1 stuff under
control panel but no way...

anyone? thanks

[PD] 5.1 sound from quicktime video files

[altern]

hi

quick question a bit on a hurry ...

is there any way to get control over sound from three quicktime video
files in order to send each to a different output in a 5.1 video
system? I have three different video projections and need to position
each of the video sounds in a different area of the space.

as far as I understand this would be impossible as quicktime video
play in GEM does not offer any control over sound because only under
mac you get the sound played, and this is in fact just done by the QT
system and not by PD

if all this is not possible withing PD, any suggestions on how to
achieve this? I am thinking about launching the videos with for
instance VLC and routing the audio by some means into PD or something
similar.

thanks

[PD] no gui refresh on macbook pro with windows 7

[altern]

hi

I have a student who is running Windows 7 Ultimate on a Macbook Pro
(not the latest model, this is about 3 years old machine). We are
using PD extended 0.42-5

The GUI seems to stop refreshing at random times. For instance numbers
output the right values but the value displayed does not get
refreshed, so the interface does not seem to respond but actually the
whole patch continues to work fine, it just does not display any
changes. Restarting PD does not solve it, we have to restart the
machine.

We are working with GEM and I am wondering if something funny is going
on with the graphics card.

anyone knows a solution to this? thanks!

Re: [PD] PyPd

if you want to use it from python just take scripts.py it has some 
examples of how to use it in the botton of the file. If you want to use 
it from PD you need all the files, scr.py and search.py just wrap 
scripts.py with pyext classes, in this case check script_examples.pd . 
There is some other utilities in the library, check the readme file for 
details. let me know any question, i have not tested it for a while so 
some parts might not work if the websites have changed their URL query

You can use Pd.py to launch Pd as a subprocess and communicate with it via

[PD] video server that can be controlled from OSC

[altern]

Hi

for an interactive installation constructed with PureData we developed 
using OpenFrameworks an app that allows to display and control videos, 
images and webcam video streams. We controlled it via OSC with a set of 
messages from PureData, so we wrote a PD patch that explains all OSC 
messages but also some abstractions that wrap the OSC messages into some 
objects, again this is to be used by students woth little knowledge of 
PD. I also wanted to implement some movement detection but since this 
was not finally used in the installation it is not really working well.


All this could be done with GEM but we needed to get the sound track of 
the video files played with the video. I just thought it would be nice 
to share it so this is the download link for the source and binaries. 
Detailed info about the OSC messages and all features implemented are 
included in the readme file within the download folder

Jose Luis Santorcuato(e)k dio:

Hi, maybe the potentiometer need a resistor,... if the potentiometer is a 10
kohms maybe yo need a resistor, i prefer work with 50 kohms potentiometers.

Using a protoboard, you must connect a general ground and  general voltage,
the wire to analog is the middle wire, check the pwm or outputs are closed.

Best regards

José
2009/11/12 


 The microcontroller in the Arduino has a single sampling capacitor that
can be connected to any one of the analog pins.
It will charge up to the voltage on the pin if enough charged particles are
available on the pin (or a path less than about 10kohm exists to a source of
current).
The cap is not discharged by the analog-to-digital conversion process or
between samples except through leakage.
If no charge is available on the pin the capacitor will continue to slowly
drain its charge from the previous sample.
It's normal and harmless unless you are in a high-voltage environment like
a thunderstorm or a nylon carpet, where much more than 5V could accumulate
on an open pin. Then it's best to ground unused inputs.

Subject: [PD] arduino problem with analog sensors
hi

not a PD question I guess... i dont know much of electrical stuff. i am
connecting two analog sensors to the arduino. One is a pressure sensor
and the second a potentiometer, they are both from an old icube.

i noticed that when i raise the potentiometer (analog pin 5) the
pressure sensor (analog pin 2) reports values ranging 0 to ~0.16
increasing together as the potenciometer goes up. It is like some kind
of residual noise comming from pin 5 that goes into pin 0.

the power cables of both sensors go together to 5v inlet of the arduino
and the ground cables go to ground pin, each of the data cable goes to
its separate analog pin.

I am using arduino from Pure Data extended using latest Firmata, so i am
just filtering out any value smaller than 0.16 coming from analog pin 0.

is there anything I am doing wrong? or is this normal?

Re: [PD] arduino melody example in PD?

[altern]

That sketch is playing a tune making square waves of different 
frequencies. That's not really the same as PWM, which varies the length 
of the pulse, but the frequency stays constant. There are a few ways to 
generate a square wave of a given freq. in Pd, if that is your goal. If 
you want to do it by modeling the Arduino's use of a timer to turn a 
signal on and off, that might be an interesting exercise. One easier 
way, though, would be to amplify and clip a sine wave.

arduino code to PD. So after some headache i thought maybe someone has 
already done this for PD?

Re: [PD] xsample freezes PD

i just compiled it from svn source and it is working fine. much easier

thanks

Thomas Grill(e)k dio:

Hi Enrike,
i'm afraid i can't help too much i'll recommend that you try to
compile the object on your system (flext and xsample) instead of using
the binary.
It would also be helpful to know where exactly it freezes (running in
gdb and printing the backtrace).
I'm abroad and therefore not able to build anything until the end of
September, but let's see if we get it running.

hi
when i run some of my patches the pd process goes to 99% CPU and the pd GUI
freezes, i cannot close
the terminal or any patch. I have to kill the process from task manager.

After some tests and found out that it seems to come from xgroove~
object. This is how it happens: I run pd, open the xgroove~ object help
file, setup pd input and output devices via ALSA. I activate DSP and
push the bang to start play the xgroove~ example.

The audio runs until the playhead goes next to around 80% of the table then
it
freezes, i can see that the PD CPU usage grows quickly just after the audio
and GUI freeze.

any ideas? this is the terminal output. not very interesting i guess.

This happened both in PureDyne with the pd installed from their packages and

I guess it is either a bug in latest version of xsample or I am missing
something in both systems.

Hey enrike!

The ubuntustudio-audio package is just a meta package that installs 
other packages, so its ok to remove it.  Ideally the ubuntustudio-audio 
package would depend on 'pd' rather than 'puredata', because the 
pd-extended package provides 'pd'.

[PD] (offtopic) voice recognition

[altern]

hi all

for a project i might involved in we need to do some voice recognition. the
setup is as follows : there is a virtual avatar that is able to perform
certain movements. It should move its moth acording to the voice from the
computer's sound input. So we do not need to recognise certain words or
sentences, we just need to match the human voice with the movements of the
virtual animation. This information would be sent to the animation software
by OSC or some other method, this is not important right now.

I am not sure if this can be done with PD or some other software. we have an
old speech detection system made in Java but it only works for wovels so it
is not so realistic. Has any of you done something similar?

thanks!

i think there is something else than just the kernel and packages. some 
tweaks on the configuration that the plain Ubuntu does not have, stuff 
like memory use, priorities and groups + permissions. But i think all 
can be done by hand.

[PD] ehu abstractions (finally) released

[altern]

hi

so finally (i think) i made it with making the patches less messy 
avoiding ambiguous situations like the ones pointed out by few people in 
the list (thanks). So there it goes
http://www.ixi-audio.net/content/download/ehu_abstractions.zip

i also added some more docs, and even translated the docs to spanish (!).

This is the description :
EHU is a set of abstractions for PureData real-time graphical 
programming environment (http://www.puredata.org , 
http://en.wikipedia.org/wiki/Puredata).  The main purpose of EHU is 
control/manipulate/analise/sequence video and audio in real-time. EHU 
encapsulates the complexity of programming with PureData to allow for 
rapid prototyping of interactive systems. EHU is developed for people 
with basic knowledge of PD but also for more advanced users to ease and 
speed up as much as possible the development. EHU also includes 
abstractions to control Arduino (http://www.arduino.cc) from PD (wraps 
pduino example by Gerda Strobl and Georg Holtzmann). Main areas covered 
by EHU abstractions are : video files, video cameras, pictures, audio 
utilities, general utilities.

And again, this is thought to be used within PD extended. It uses few 
abstractions and externals included there. Check the readme file for 
more details on which ones are used and other details.

same problem i got with my build. PD starts up and gets frozen when 
loading the externals. I "solved" it by comenting out OFLAGS=-O3 from 
the config-lnx-pd-gcc.txt configuration file. If your file works in your

gate and counter are from cyclone, prepend from iemabs. So the complete 
list of dependencies should be :

arduino freeverb~ Gem ggee import list-abs mapping unauthorized xsample 
  zexy counter prepend gate

many thanks, i will include this in the documentation.

as i said the abstractions have been developed to be used within 
PD-extended which currently includes, as far as i know, all of them but 
arduino and xsample (this last one only missing under linux i think).

I went for PD-extended after couple of bad experinces where i wasted 
days trying to write code in pd only to find that there were externals 
included in pd extended doing the job better, more complete and far more 
efficient than my spaghetti code.

yeah, i know that... i think it is the only external I use that is 
missing in the current version of PD extended and only the Linux 
version. I had to compile it myself which included compiling flext, if 
you need a hand i think i still have it fresh, i did it two weeks ago.

[PD] ehu abstractions to be released

[altern]

hi all

Lately I have done a lot of work on some abstractions, so I thought it
would be good idea to share it with the list to see if there is any
feedback about them.

The main purpose is to allow manipulation of video and audio in real
time with PD making its use as easy as possible.  It is mainly developed
for students to use in ~two day long PD workshops, but i guess it can be
used by anyone. I find myself using some of them all the time, specially
when prototyping or doing fast sketches, but then again I guess some of
them are fairly trivial. Students in these workshops don't usually have
the time (or/and background) to go for a full on introduction to PD.
Hence this patches are just ready-made solutions to be used with very
general knowledge of operating with PD.

So there are abstractions to manipulate video/webcams/pictures with GEM,
some sound utilities, and some general utilities. There are also some
abstractions to control Arduino from PD (just wraps/rewrites pduino
example by Gerda Strobl and Georg Holtzmann into a set of separated
abstractions and adds some small functionalities here and there).

They have been thought to be used in two different scenarios. On
the one hand a "live coding" situation, this is why the abstractions
include GUI controls (exposed via graph on parent) that allow to control
its internal state. On the other hand, they are thought to be used in a
installation situation, where the interface is not used. So each Gui
control corresponds to one inlet. They have been developed to be used
with PD-extended, few objects from externals included in that distro are
used.

It is also possible that some might already exist in other abstraction
collections or externals, i dont know all abstractions/externals in PD
so if anyone sees anything repeated please let me know. It
would be good to hear feedback about it, I know there are similar
projects being developed at the moment. I think it would be nice to end
up with a set of ready made objects that can be used by that type of
users. It is always nice to start with something that works and then
slowly go in depth into the programming.

this is the link to download the latest version
http://ixi-audio.net/content/download/ehu_abstractions.zip

There is a readme.txt in the documentation folder that explains all
abstractions included and how to use, there is also a set of examples in
the examples folder and each abstractions has its help patch included,
so once it is copied into extra folder the help system should work fine.

if anyone has questions please just mail me. thanks for any feedback

[PD] gem pix_texture crashes PD

[altern]

hi

i was testing a gem patch on a computer from a university i am giving a 
workshop, this is supposed to be a good machine for graphics. When i 
import a texture and open the gem window it crashes inmediately. The 
machine is running win XP with latest PD 0.40.3 extended.

i used the Gem's pix_texture help patch to try different settings with 
"quality" and "mode" also tried different images. Same problem always. I 
run pd from console and it did not print any error message at all, just 
quits.

the machine has a special graphic card, it is a matrox Parhelia LX, from 
matrox millenium P-Series. I think it is used for stereoscopy or 
something like that. Could it be that graphics card and Gem do no like 
each other?

Ah, I tried with two different machines with same card, same problem in 
both.

thanks

Re: [PD] py and xsample in 0.40.3 extended under Linux

[altern]

hi thomas

i decided to give it another go. i checked out the latest svn 
flext/xsample and py sources.
so i did
$ apt-get install stk libstk0c2a libstk0-dev libsndobj2c2 libsndobj-dev
then i run
$ bash build.sh pd gcc
then edited the linux file config-lnx-pd-gcc.txt
i noticed i needed to have the pd source, i think i got it from the 
pd-extended source. This is the content of config-lnx-pd-gcc.txt after 
editing

PDPATH=/usr/local/src/pd
FLEXTPREFIX=/usr
OUTPATH=pd-linux
INSTPATH=/usr/lib/pd/extra
STK_INC=/usr/include/stk
STK_LIB=/usr/lib/libstk.a
SNDOBJ_INC=/usr/include/SndObj
SNDOBJ_LIB=/usr/lib/libsndobj.a
#MFLAGS=-j 2
UFLAGS=-msse -mfpmath=sse -ffast-math
OFLAGS=-O3
OFLAGS+=-march=pentium4

the again and finally
$ bash build.sh pd gcc
$ bash build.sh pd gcc install

it did not complain at all, then i tried to compile both py and xsample. 
  All went ok but when i run PD it stays frozen exactly at the time of 
loading those externals. I tried removing them from extra and PD was ok 
again. Both of them cause the same behaviour. I guess some path or 
option in the config file is wrong. Any ideas? I think something went 
wrong because it did not install it properly as far as i can see. The 
flext/build.sh is not anywhere in my file system but in the svn checkout 
build directory. This directory is empty /usr/lib/flext but this file 
does exist /usr/lib/libflext-pd.so

Nice that i almost managed to get it done, but there should be a way to 
make this process simpler

Some ideas about the process:

  i dont think this explanation in the docs could be a bit more elaborated
"From a shell run
bash ../flext/build.sh
(you would have to substitute ../flext with the respective path to the 
flext package)"
i know it is stupid but it took me few minutes to realise i need to run 
that script from the main folder of the code i want to compile. Also it 
would be nice to have a description of the compilation flags. I know 
this is printed by the script itself, but it is nice to know things 
before they happen.

It would be also nice not to have to find and edit the paths to all the 
libraries (STK, SndObj), this is quite confusing specially because some 
files names are not lowecase so initially i did not find them until i 
noticed it (sndobj.h was SndObj.h). But i guess this has to do with the 
autobuild you mentioned in your mail.

thanks.

Re: [PD] py and xsample in 0.40.3 extended under Linux

[altern]

finally i took the binaries from 0.39 and places in the 0.40.3 extra 
folder, then i had to apt-get install python 2.4 as Ubuntu Hardy only 
has by default python 2.5. Everything seems to work fine so far.

still it would be nice to have at some point a more up to date version 
of the binaries included by default, i guess there are reasons for not 
having them currently.

thanks

[PD] py and xsample in 0.40.3 extended under Linux

[altern]

hi

just a wish, i dont want to puch anybody... it would be great to have py 
and xsample externals included in PD-extended 0.40.3 under Linux, like 
they were in previous PD extended versions.

I want to compile py, but first i need to compile flext. I started two 
hours ago and i am not getting much closer to getting it done. It is not 
so trivial to do. I do compile once in a while (jack, freebob and some 
apps) but usually i find it easier than this. I keep trying...

i mean i was looking for an specific command to only switch on/off the

mmm... are we talking about the same thing? i already searched the list 
before sending the mail, and now i was looking for it for two hours. i 
searched the list over and over again and also the documentation and 
examples in pd extended. I discovered few nice things about the PD

i have some awful GEM code which i wrote overnight two years ago. every 
time i try to update it to latest Gem i dont get very far and breaks my 
nerves ;) I have a workshop in a couple of weeks and i am not sure it is 
a good idea to do it now... but i will have to do it at some point.

[PD] GEM - pd 0.39 crashes with pix_movement + pix_blob

[altern]

hi all

yesterday i tested a GEM motion detection patch with a friends laptop to 
find that PD crashed really badly after few seconds. It looked to us 
like it crashed when there was big changes on the incoming data (sudden 
movement in front of the camera...).

The funny thing is that my friends laptop is a brand new Asus laptop 
running Vista and mine is an old IBM with XP. So the Asus should be much 
more powerful than mine... but there is no problem at all in mine with 
same patch.

We were using PD extended 0.39 on Vista, the camera is integrated, I 
could not check the type of graphics card and camera (no time sorry). 
Just noticed that there was no output on the PD console at all, just 
crashed.

We noticed that we could remove either pix_movement or pix_blob from the 
chain and then it would not crash. So it looked like the combination was 
problematic.

i know this is not very good description of the problem but does it ring 
any bell? thanks!

no i am not superstitious. i get this error

after changing to port number 2 i get this

mm so there is no solution, in this case i will have to set the port 
manualy every time i startup. it is ok but if this was for an 
instalation it would be a problem. i guess using more up to date 
versions of the externals involved would be good, but i am having some 
issues with 0.40 and some old GEM patches

i am using pd 0.39 extended on XP to control arduino via pduino. Every

Otherwise i get error when i try to connect to port 13

I guess this question has little to do with PD itself but, is there a

Re: [PD] worldwide weather forecast into PD

hi hans

thanks for the link, i checked it briefly yesterday, not sure if i will 
be able to find the part of code i need, it seems a bit too bit and it 
is C, probably easier to do it myself in python.

The weather.com city codes look like the same as weather.yahoo.com it 
seems to me that they both access the same system to get the data. thats 
interesting, i found already several weather forecast systems that are 
actually the same in the background.

no it is just a set of patches that should be used in different 
situations by other people. they should be aware of this potential risks

thanks for the link, i am at the minute testing BBC weather, i can send 
a form witih the name of the city i am interested in and then parse the 
resulting page to get the ID. This works fine, i am now trying to parse 
the XML data. The "only" issue with this is if there are several cities 
with the same name, it offers you several choices, currently i am going 
for the first one.

[PD] worldwide weather forecast into PD

[altern]

hi

anyone knows of an online worldwide forecast service? I am developing 
some python scripts with Pyext external that retrieve different type of 
data from the net into PD.

At the moment i have been using yahoo weather, this is quite handy 
because they have RSS feed that can be easily manipulated from python 
and returned into PD.

Currently i have scripts that tell me the external IP of my computer and 
  another one that uses the IP to retrieve geolocation data (lat, long, 
nearby city, country ), using this i think i should be able to ask yahoo 
for weather data of an specific city and country and from there access 
the RSS.

However I think there are some copyright issues with yahoo weather. I 
read a notice in the HTML source of yahoo weather saying that this data 
is not to be used without permission
" ...You are prohibited from using or repurposing this data in any way 
without express written consent from Yahoo! ..."

I guess i could pretend i did not see the notice but maybe there is some 
worldwide forecast service that would allow me to use the data?

thanks

[PD] pyext thread question

[altern]

hi

just working with pyext after long time not using it. Couple of things

First, on PD extended 0.39.3 on linux at least (not sure about the new
pd version) on the docs folder there is a folder manuals/py which only
contains license, readme and an empty folder called scripts. The actual
examples for py are actually located at examples/py
I suggest all could be either in manuals/py or examples/py, in any case
having the empty "script" older is a bit confusing. I thought for a sec
that the docs where just not included with PD extended to later find
them under examples.

Secondly, I am working on a script that needs to be initialised on load
with _detach set to 1. According to the docs I could solve this in PD
passing a message detach 1. This works fine but I need to set this from
Python on initalisation. Again the docs say I should set (class?)
variable _detach = 1. But this does not work for me, it runs as if it
was still set to 0:

class myclass( pyext._class):
_detach=1
_outlets=3
... and so on..


the script example (threading.py) has this documentation on this issue
""" _detach([0/1]): by enabling thread detaching, threads will run in
their own threads
"""
but the pd patch (thread-1.pd) say this takes three valid values (0/1/2)

Finally after some digging in python printing dir(myclass) and
help(myclass) I found that there is a (private?) class function called
_detach that can be used like this
myclassname._detach(self, 1)

using this funtion does not look very good to me (i guess it is
private). On top of this the code is not executed on initialisation, as
i need, but only when the function is called. any ideas on how i can do
this? maybe extending __init__ ? but i am not sure how to do this. I
hope i made myself clear ...

thanks

which Linux are you on? if you are on a debian or ubuntu there are .deb 
packages from Hans website
http://at.or.at/hans/pd/installers.html
there are some instructions on how to install packages there as well.

you are likely to get errors telling you that some libs are missing, 
again if you are on a debian or ubuntu system you can use synaptic 
package manager to get those libs, then try again to install the PD package.

this how i would do it, but maybe someone knows an easier way?

sorry i forgot to say that you could just go to synaptic and search for 
pure data and install, this would give you an older version but maybe 
easier to deal with missing dependencies because it will try to solve 
them automatically. Try this first if you dont care about PD version you 
  will be running.

i know, i know... but i dont have the second machine with me. I also am 
fairly sure we had both same version when I did the tests 0.39-3 
extended with GEM 0.91-cvs compiled Dec 11 2006. Pretty old one...
So I thought this error might be more to do with some codec not being 
installed on the system, or some windows version issue. I am going to 
try to get more info on the second system.

[PD] 3gp videos with GEM on windows

[altern]

Hi

I am using 3gp video with GEM on windows and linux. Under windows XP on 
some machines pix_film does not return the right video length in frames, 
it returns 1, testing with same video and patches in another machine 
returns the right length. Does this sound like some Windows issue? maybe 
some codec that needs to be installed? I need to find a format for video 
that works fine crossplatform.

i also noticed since i upgraded to latest GEM that the 3pg videos play 
its sound after being loaded. This does not seem to be done via PD 
(sound is off), the sound plays once after the video is loaded. If the 
video being rendered the sounds keeps playing looped but chopped, with 
very short periodical interruptions.

[PD] Pd-0.40.3-extended-rc1 and py external

[altern]

hi

I am testing a patch that uses py external on windows XP with both pd 
extended 0.39.3 and 0.40.3 rc1. Because I have python 2.5 installed on 
my machine and the external is compiled against 2.4 I include in the 
same folder as the patch the python24.dll and also python's libs, Lib, 
include and DLLs folders from the python 2.4 distribution.

This works fine with PD 0.39, the py external loads ok and my scripts 
run fine. But same patch in same machine opened with 0.40.3 rc1 does not 
work. PD says it cannot find python24.dll.

I guess it is not looking for it in the folder where the patch is.  Are 
there changes in search path from version 0.39 to 0.40? Do i need to add 
it manually or something like that?

thanks

It receives a list of times like

[PD] audacity and PD problems with Jack

[altern]

hi

I am using Audacity to record output of PD via Jack on Ubuntu Studio. I 
am also having supercollider sending audio to PD. Audacity is causing 
some discontinuities in the audio and the recording has gaps every 5-10 
secs. I tried recording with supercollider and i did not get this problem.

Could anyone suggest some basic sound recorder that works with jack? I 
just need to record the jack output, no need for multitrack or editing, 
just be able to select the sound format, frequency and amplitude maybe.

There are some I saw searching with synaptics but I thought maybe 
someone here has some suggestion.

thanks

Re: [PD] gemhead render argument

hi again

another issue i am getting with GEM on linux. When I run a patch that 
uses GEM that uses the webcam while the VGA output of the laptop is 
connected to an external monitor the X crashes ,  like if I press 
CTRL+ALT+Backspace.

I guess it has more to do with the system configuration than with GEM 
but I am not sure...

[PD] gemhead render argument

[altern]

hi

i am getting different behaviours with same GEM patch under linux and
windows. The patch is rendering a webcam image with pix_video and then a
basic rectangle with no texture on top of the webcam (using pix_blob to
analyse the camera and move the rectangle around). Each has its own
gemhead and they are separated in different abstractions.

While in windows all is rendered fine, linux does not like it the
rectangle was rendered but the webcam image wasnt. The only way to get
it to work was to put some render argument of the rectangle like 2. So I
decided to set that value to $0 on loadbang, this should give different
numbers to each instance of the abstractions. (Note that i dont have a
clue if this is bad idea). Both the camera image and the rectagle are
included in abstractions.

The result was kind of ok, now linux was more happy with it but still
sometimes the webcam image goes off again. This happens for example when
I move the gem window or after ~10 to ~20 secs. Also if i open a PD
subpatch.

When I switch rendering off on the rectangle's gemhead and then the
webcam goes live again... When I switch on the rectangle it takes some
secs to go off again... If I dont turn on the rectangle the webcam stays
alive.

The webcam gemhead gets set to 1004 and the rectangle to 1005 from the
$0 arg of the abstractions they live in.

I guess this must be some problem with having two gemheads but i am not
sure why this problem is not happening at all under windows, so it looks
like a linux issue. Anything i can do to avoid this problem?

Sorry if the explanation is not very clear...

thanks!

I was told there are some windows apps that allow to create standalone

me too and i would love to force them to use linux on this just so that 
they can see that there are "other worlds" in the galaxy. But I still

[PD] pd extended on windows with no installer

[altern]

hi


I am going to teach a short intro to PD at a uni where it is really 
difficult to get permission to install applications on the computers.

is there a way to have pd extended to fully work on a windows machine 
without running the installer? I need it to load the externals on 
startup, this is important.

I tried copying it from my machine but it does not load the externals i 
need and i cannot introduce them manually into the startup because i 
dont have permissions to mess with the registry. I could run PD from a 
bat file but i dont like this solution, the windows console pops up and 
experience tells me this is scary for this students.

is there any simple solution to this?

thanks!

Re: [PD] Sending data from Processing to PD

[altern]

hi tocayo ;)

I would use OSC, it is the same and very likely to be easier. The 
processing OSC tutorial is nowadays trivial to use, same goes for OSC in 
PD.

Check the example in the oscIxiExample folder inside this zip
http://www.ixi-audio.net/content/download/tutorials/processing_tutorial.tar

There is a PD example and a Processing example as well. aIf you have any 
question just email again.

good luck

but we might need up to 6 to 8 video outputs, thats too much for the 
same machine. Thats why I thought about having a machine per video 
output connected to a LAN and synchronised via OSC.

[PD] synchronised video outputs

[altern]

hi

I need to have several video outputs that run in sync. A friend who 
works in a art exhibition space told me there would be couple of 
solutions for this but both involve buying pretty expensive equipment 
like special DVD players.

I thought then that a solution for this issue could be to have several 
computers on a local network playing video (with GEM) and synchronise 
them via OSC. But I dont have any experience doing such a thing, never 
used OSC for anything similar. Also I dont have a clue about how to 
synchronise together videos.

Has anyone done anything similar? any experiences to share?

thanks!

bad luck. just compile everything from latest source and make sure you 
quit all unecessary processes, that should be enough to make it more 
stable. Otherwise buy a firewire PCMCIA card, they are not that expensive.

hi patrick

I have a terratec phase X24 and the only problem I have is because of 
the firewire controller on my laptop (IBM X32) which seems to be crap (a 
Ricoh). So it is not the soundcard. I was told on the freebob list that 
I should buy a PCMCIA firewire card to solve this. I disabled cron and 
anacron (one of them was starting updatedb causing big trouble with 
jack) and I stop the wifi card while I use the soundcard. I also 
compiled freebob and jack from latest stable source. After all this it 
works better, jack still quits but takes couple of hours to happen.

Regarding PD I get clicks when switching desktops, I use Fluxbox on 
Ubuntu Studio. This does not happen with other software like 
Supercollider. I guess I need to play around with PD startup flags. I 
havent tested latency with test patch. Thanks for pointing into the 
ath_pci issue, I will test to see if this makes any difference.

Re: [PD] GL: invalid value

hi

I think I had same problem. try sending
mode 0 message to pix_texture.  maybe quality 0 as well. I found that 
some graphic cards like mode 0 and some others mode 1.
