[rradical]example.pd bugs?
by chun lee 08 Oct '04

08 Oct '04

Hi there: Finally got the example patch in the instruments directory loaded up with no errors. But I found a few things that seems a bit strange. 1. in the sub-patch "interna" in analosc.pd. I had to swap the order of $0-wave-out/in, $0-warm-out/in and $0-inst-out/in to get it to work. In addition, the $0-lfo parameter where left out without the "-out" and "-in" bit. 2. in the analogue.pd, I got: error: scale: no method for "float" I had to get rid of the scales the replace it with "/ 127" and its ok. 3.the level in which the adsr-engine seems to be quite low so I had to take out the double "*~" that come after it. are these bugs? I still have not quite get the hand of it in this patch. Apologies if I am wrong. Cheers CHUN

Re: [PD] ports again
by Andres Cabrera 08 Oct '04

08 Oct '04

I've seen problems with thing like McAffee firewalls and the new windows service pack. You are asked once if you will allow pd to access the port. If you answer no, pd will not run. You need to find the configuration menu for whatever is bolcking the ports (The McAffe configuration or the Windows security center), and unblock pd. The weird thing in your case is that pd runs sometimes...

Hans, More info would be awesome. I really respect the work you have done for pd. Do you have any online documentation of some of your projects like pictures or movies? I would be excited to know what the motors looked like and did, and where you acquired them.

pd/pdp(+pf)/pidip/gem on gentoo - pseudo-howto

hi, this is an excellent howto for gentoo users, i just did the install following these steps and it was wonderful... thanks for that aym3ric just some things to contribute to it... - need to do # emerge lame before doing the ffmpeg install (since we are calling --enable mp3lame --enable vorbis in the ./configure for ffmpeg) - emerge avifile had a few dependencies and so it does an emerge ffmpeg if you haven't already emerged it. so what i did is this: # emerge unmerge ffmpeg # make install (in my ffmpeg-cvs directory) # merge inject media-video/ffmpeg-0.4.7 (installs a stub so portage thinks its there still) so far i havent seen any problems with this method, but not sure what will happen since i did it just 5 minutes ago... pd/pdp/pidip & Gem _seems_ to be ok ;) - also for pidip install, i had to do: # cp fonts/* /usr/X11R6/lib/X11/fonts/TTF cheers, naveen --LQksG6bCIzRHxTLp Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="pd-gem-pdp-pidip-gentoo.txt" ------------------------------------------------------------------------------ Pure-Data / Gem / PDP-PiDiP / PF on a gentoo box. ------------------------------------------------------------------------------ step by step howto (according you already have alsa...) 24/08/04 - v.1.0 ------------------------------------------------------------------------------ -- Changes v.1.0 - first version, probably the last. -- Notes everything should be fine :) you may have already some deps installed. ** Pure-Data -- some deps for pd to compile and run # emerge jack-audio-connection-kit # emerge tk (it will get tcl as well as dep) -- creating a common install directory % cd ~ % mkdir pure-data % cd pure-data -- downloading the pd sources and extract % wget http://www-crca.ucsd.edu/~msp/Software/pd-0.37-4.src.tar.gz % tar xzvf pd-0.37-4.src.tar.gz % cd pd-0.37-4/src -- configuration and compilation # ./configure --enable-jack && make && make install ** PDP & PF -- some deps # emerge gsl # emerge libquicktime -- downloading the sources % cd ~/pure-data % cvs -d:pserver:anonymous@zwizwa.fartit.com:/usr/local/cvsroot login % cvs -d:pserver:anonymous@zwizwa.fartit.com:/usr/local/cvsroot co libtile libpdp pdp -- configuration and compilation % cd ~/pure-data/libtile # ./bootstrap && ./configure && make && make install % cd ~/pure-data/libpdp # ./bootstrap && ./configure && make all_install % cd ~/pure-data/pdp % autoconf % ./configure --enable-mmx --enable-pwc --enable-pf (mmx and pwc are optional) # make && make install ** PiDiP -- some deps # emerge imagemagick # emerge imlib2 # emerge libtheora -- ffmpeg -- we need to do something here if you want to keep the ffmpeg ebuild from portage # emerge ffmpeg % cp /usr/portage/distfiles/ffmpeg-0.4.7.tar.gz ~/pure-data % cd ~/pure-data % tar xzf ffmpeg-0.4.7.tar.gz % cd ffmpeg-0.4.7 % ./configure --enable-mp3lame --enable-vorbis % make -- downloading the sources % cd ~/pure-data % wget http://ydegoyon.free.fr/pidip-0.12.16.tar.gz % tar xzf pidip-0.12.16.tar.gz -- configuration and compilation % cd pidip-0.12.16 % ./configure --with-pd=../pd-0.37-4/ --with-pdp=../pdp/libpdp --with-ffmpeg=../ffmpeg-0.4.7 % make # cp pidip.pd_linux /usr/local/lib/pd/extra # cp doc/* /usr/local/lib/pd/doc/5.reference ** Gem -- some deps # emerge glut # emerge tiff # emerge jpeg # emerge freetype # emerge gltt # emerge libquicktime (already there with pdp) # emerge mpeg-lib # emerge libmpeg3 # emerge avifile -- downloading the sources % cd ~/pure-data % wget http://gem.iem.at/download/gem-0.90.0.tgz % tar xzf gem-0.90.0.tgz % wget http://gem.iem.at/download/GemLibs-linux-1.tgz % tar xzf GemLibs-linux-1.tgz -- configuration and compilation % cd gem-0.90.0/src/Gnu % ./makeauxlibs % ./configure % make # make install && make installdocs ------------------------------------------------------------------------ now create a .pdrc file in your home dir and add at least those lines -path /usr/local/lib/pd/extra -lib pdp:pidip:Gem --LQksG6bCIzRHxTLp-- ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

ports again
by Ales Zemene 08 Oct '04

08 Oct '04

sorry, didn't make it clear before : the 5400 port is absolutely ok, problem comes if you try to run pd on server with firewall, closed ports, etc. it is simply not enough if i leave only 5400 port open. pd (sometimes) does not start. >>Ales Zemene wrote: >> ...after pd starts there is >> 5400/tcp open pcduo-old >> which closes again after stopping pd, >> i guess pd needs some another port open in order to start ? >IOhannes wrote: >well, 5400 is the port pd uses to talk to pd-gui (because pd and pd-gui >are connected via a "network", this makes it so hard to work on win95, >where you don't have a tcp/ip-stack by default) >if you don't want this port to be opened, you could try starting pd with >"-nogui". >mfg.a.dsr >IOhannes for unknown reason it *mostly* works after restarting system. perhaps it has something to do with iptables rules. thanks [ bang ( | [ Ales Zemene ] | | IRC chat server : irc.kunstlabor.at| | channels : #puredata #kunstlabor |

-rt flag and shell scripts
by rat＠telecoma.net 08 Oct '04

08 Oct '04

hi, maybe somebody can comment on that: the intention for the -rt flag for the patch i use was to reduce noise which i got because of heavy data sorting by a shell script which provides the data for the patch. by now using the -rt flag it even gets worse, the somtimes noise mutated to dropouts + heavy clicks. i call the shell scripts via the shell external. is it possible that the execution of the scripts is given priority because of calling them from pd -rt ? if yes would there be a way around this ? merci erich ---------------------------------- http://randomseed.org On Wed, 6 Oct 2004, Martin Pichlmair wrote: > > hi erich, > > afaik suid runs the program under the owner's name. so in your case pd > has to be owned by root (the patch does not matter) in order to run as > root's process. > > chown root:spinne pd > > should do it. > > lg > martin > > > On Oct 6, 2004, at 14:47, <rat(a)telecoma.net> wrote: > > > hi, > > > > i want to run pd with rt flag as a user. > > so i searched the archive on how to do > > this. > > > > besides that there were several solutions > > regarding chmod - non if these are working > > for me.?!% > > > > at the moment its set to chmod 4755: > > > > -rwsr-xr-x 1 spinne spinne 1839956 Oct 4 13:18 pd > > but i get a: realtime setting failed because not root > > > > if it works with -rt, should i get some > > output on the terminal regarding rt > > capapilities ? > > > > is */bin/pd the only file which needs a chmod ? > > > > i would very thankful for some suggestions > > > > merci > > > > erich > > > > > > > > _______________________________________________ > > PD-list(a)iem.at mailing list > > UNSUBSCRIBE and account-management -> > > http://iem.at/cgi-bin/mailman/listinfo/pd-list > > > > > attacksyour.net/pi >

Re: pd 0.38 test and GEM
by Hans-Christoph Steiner 08 Oct '04

08 Oct '04

This is really a post for the list, since they are many people who can answer this question. I CC'ed it. The .pdrc should work fine. Miller introduced the ~/Library/Preferences/com.ucsd.pd.plist file in 0.38test? which saved the prefs set from within Pd.app. At the pd~conf, IOhannes, tigital, and me worked quite a bit on integrating Gem better on MacOS X, so there should be improvements in the future. .hc On Oct 5, 2004, at 4:30 AM, Nick Dan wrote: > Hi, I tried running pd.app 0.38 test but couldn’t get it to load a > patch I made that included the GEM library.

pd audio interface LATENCY
by Owen Cartwright 08 Oct '04

08 Oct '04

Hello, I have a question regarding audio latency with PD and windows. I am currently using an Emagic 2|6 usb audio input device to run live audio into pd. As is expected, there is some latencey involved in this process, but I seem to have MUCH more latency time than my friend running Max/MSP on his Macintosh laptop with a similar usb audio interface... why is this?? The emagic device claims to have super-low latency, but it is almost useless for performing live with PD. Any suggestions? Where is all the latency comming from, and why is there so much more than with my friend's setup? My computer is 3.06 ghz with 1 gig ram and windows XP. I would appreciate any and all advice on this matter. many many many thanks to all who post on this forum to begin with anyway, you have been very helpful to me. Thanks, Owen Cartwright

Anyone else using Pd in Cologne besides Luigi and > me? That\'s why being in Graz or Amsterdam is so good. I also feel your pain. Over here in the US anything except crappy alt/pop/rock is shunned. I can takl to two professors at the university that use MAX/MSP, but otherwise Im all alone and have to solve all my own problems, with the help of the friendly and kind people of this list of course! I should narrow my locality to Colorado, as there are most likely people using PD in NY and San Fran. > > and why it is the most important piece of free software in current > > audio/visual development! > > But this we *do* know. ;) Ive dumped ALL of my time, energy and money into getting PD working well for this very reason. Viva PD! (Though I cant say Ive got it working well yet...) -thewade
