Re: [PD] USB audio on Win laptop
by David NG McCallum 22 Jul '03

22 Jul '03

Martin, I'm using an M-Audio Quattro and it seems to work pretty well, if you're looking for an "affordable" solution...

Installation on linux
by Philippe Langlois 22 Jul '03

22 Jul '03

HI All, Just to give a brief account on my experience of building PD on linux: using debian linux, i got the deb packages and when i ran it, i couldn't get the audio out even if my xmms and mpg123 were playing fine. I tried to recompile 0.36 and 0.37-testX (see other problems later) but it changed nothing. In fact, there's a workaround here: instead of running with pd -oss try to run with: pd -oss -noadc There's no sound input, but at least you can PRODUCE some sounds. Better would be to install ALSA. That's another story once again. It seems to beMUCH easier to install ALSA by enabling its option in the Kernel in kernels 2.5.X than to compile it as external modules with kernel 2.4.X. Compiling PD was another set of problems: - you have to manually add -I/usr/include/tcl-8.3 or so to your makefile after the ./configure process otherwise it does not compile. - you may have to change the #include "tk.h" into a #include "t_tk.h" for t_main.c - you may have to delete the options -Wall and -Wnoshadow in order to prevent compile abort due to "declaration of 'xxx' shadows a global declaration". - you may have to add -ltcl to the makefile in LIB in order not to have linking errors. Remember that's based ONLY on my experience and may not reflect a proper way to do things considering that i'm starting with PD. Also, I was using kernel 2.4.18 on a laptop with an ALi M5451 as an audio card. My .2 cents and lots of hope and strength wishes to everybody who is starting the adventure ;-) Philippe.

parallel port access?
by Lex Ein 22 Jul '03

22 Jul '03

How can PC printer port bits be driven directly from pd? I'd like to write to I/O port 378 with byte values from 0 to 255 to control 8 port bits at a time. I can run pd under Win98, Win2000, WinNT, or Linux. I suspect this may be easiest under Win98 (no I/O protection). Any suggestions would be welcome. Thanks. Lex

changing blocksize
by Roman Haefeli 22 Jul '03

22 Jul '03

hi for some experiments with fast fourier transformation it would be nice to work with a bigger blocksize than 64 samples. but my pd computes audio only with a blocksize of 64samples (my pd runs under w98), even i try a blocksize smaller than 64 samples. from what are the allowed blocksizes dependent? what should be the biggest and the smallest possible blocksize? what means the second argument for the object [block~]? thanks --------------------------------- Gesendet von http://mail.yahoo.de Jetzt buchen!

Re: [PD] GEM (cvs) undefined symbol (Mesa, NVIDIA driver)
by bbogart＠ryerson.ca 22 Jul '03

Hello Martin, I've not used the gem packages, only even compiled from source, but I've been suing gem with Nvidia drivers version 1??? 2??? 3??? and 4??? This is before the single-install drivers currently on the site. Why don't you try compiling from source?

pd online reference
by Andre Schmidt 22 Jul '03

22 Jul '03

hello pd-community, (i've moved my earthly location and it took a month to get me a new internet connection, so i hope i haven't missed anything wicked...) well, to the business: i want to do a "comprehensive" online reference for PD as my first project on my newly ordered root-server:) heres a rough code on details i came up conserning pd objects. would be happy for any suggestion/info ! #####################################################PD_REFERENCE### create table REFERENCE ( OBJECT char(16), # name of the object, you know; tabread, samphold~, etc... VERSION char(5), # version of the object, assuming start at 0.0.1 ### ? or should i store it as number ? CLASS char(32), # class of the object eg: math,audio,text... ### ! more than one class for one object; seperated with comma ### ? what classes do we have ? LIBRARY char(16), # in which library is the object; internal,zexy,gem... HOME char(64), # homepage of the object/library STATE char(8), # the state of the object (alpha/beta/stable...) INS int(1), # how many inputs does the object have ### ? do we have objects with more than 9 ins ? OUTS int(1), # how many outputs does the object have ### ? do we have objects with more than 9 outs ? INS_TYPE char(64), # type of input(s) like: "bang,float;float" # that would mean input1 takes bang&float and input2 takes float OUTS_TYPE char(64), # type of output(s) INFO char(255), # info/description of the object ### ? is 255 chars too much ? INS_INFO char(128), # info/description for the inputs (seperated with semicolon) ### ? do we need this ? OUTS_INFO char(128) # info/description for the outputs (seperated with semicolon) ### as a newbie db admin i just love much info :) ); ##############################################################EOF### 1 big question for mySQL admins before i can start: ? should i put all externals seperate in their own tables ? - would be better for updating, but i think(with out knowing)its "easier"/faster to query from one table. or if it doesnt matter, i think i will use seperate tables... you're also welcome to send any comments directly to me at: andreschmidt76(a)arcor.de (yep, deutsch geht auch) cheers -andre schmidt ps. i'm doing this on my spare time (thats sadly not much) so please be patience... pss. any PD'ers going to Chaos Communication Camp in Germany ? http://www.ccc.de/camp/2003/index.en.html

Catalonian n00bness
by plagasul 21 Jul '03

21 Jul '03

Hello everybody. I read somewhere that n00b questions are allowed on this mailing list. So here we go. I'm having problems understanding some of the examples provided under the DOC folder of PureData. When going across those tutorials i found some language problems. Understanding How do Puredata works explained in english, when i am spanish. . (and my english is not so good) is like trying to learn German with american textbooks. So that's why i encounter some problems while understanding basics as the TRIGGER or how to manage inlets and outlets for a patch that goes inside a box. My question is.. am i the only active Puredata user of Spain? I suppose that no... i'm not... so i hope someone here from Spain... or just a spanish talker will take a little time to reply me and.. hopefully help me with those basics in order to go deeper in Puredata... My contacts are: plagasul(a)soulseekrecords.com plagasul(a)yahoo.es or if u use msn messenger: sesentaycuatro(a)hotmail.com I'll keep an eye on this list to see if someone can give me advice. Many thanks in advanced. Greeetings from Barcelona.

GEM (cvs) undefined symbol (Mesa, NVIDIA driver)
by Martin Dupras 21 Jul '03

21 Jul '03

Hi, I've got a new problem. I have a redhat 9 linux box with an Nvidia GeForce4 card, and planet-ccrma packages installed. I've just tried running pd with gem (from the planetccrma packages) and got an 'undefined symbol' error. Recompiled gem from CVS and got the same problem. After digging for a while, I found this page (http://www.opengl.org/discussion_boards/ubb/Forum4/HTML/000943.html) One of the posters seems to imply that the nvidia linux drivers don't support those functions. I personally very much need the nvidia drivers on that machine since the standard nv driver won't handle twinview. The questions: 1) would it not be possible to change the gem makefile so that it does compile, minus whatever objects rely on whatever is missing/not working? 2) could someone explain to me how gem uses Mesa, and the glx functions? I'm very fuzzy on this. 3) Is anyone using the nvidia linux drivers AND gem with success? Many thanks! - martin

Gem and particlecontrol
by pettjoha＠khio.no 21 Jul '03

21 Jul '03

hi I'm working on a "swarm"-like particlesystem in Gem using a combination of objects, it looks nice, but I have problem getting full control, some particles just shoots away, never to return..Is it possible to keep the particles from straying, for example by putting up restrictions for how far away from the source the are allowed to travel or to get them to collide with something, to put them inside a box so to speak? I don't want the particles to leave the window at any time(except from when they die).. I am using the part_orbitpoint-object for the main control. petter(beginner)
