Re: [PD] Pack problems

Hello Jordan, Well, you understood correctly that "$0" is the best way to localize certain variables in your patch. But if you're looking for more info, check the help documents in the /pd/doc/ folders called "dollarsigns" or "locality". I think that what you might be MISunderstanding is the use of ATOMS. For example, your patch didn't work because: 1. putting "$0sample" into a message box is very different than typing "symbol $0sample" into an object box or message box. 2. "Lists" come in two forms (sort of)...in one form, a list is really just a group of messages or numbers...in another form, a list is created 'explicitly' by preceding a group of messages by the word "list". However, the strangest part is that most objects in PD will act differently depending on which form of list you send to them. I suggest you familiarize yourself with the [float], [symbol], [int], and [route] objects and do some reading about "atoms" in the pd/doc/ folders. There's very good reason for all these little idiosyncrasies. As in all programming environments, it is very important to understand the usage of "content types". For example, a phone number like (555-1234) could be considered type "text" or type "number". If it is "number" then the program will assume that your answer is -679!! (a - b = c ...it's math) But if you want that phone number to remain a phone number, then you'd have to tell the programming environment that it's actually TEXT to prevent the computer from calculating it as a number. Likewise, [soundfiler] wants a COMMAND. It wants to receive a sentence which says "read this file and put it into this array". It doesn't want to receive a LIST which says "I am a list" [pack] wants to receive specific types of atoms. That's why we had to send it a "symbol" called "$0sample" instead of sending it TEXT (via your message box). [pack] outputs a "list" though...that's what confused you I think. I hope I've helped instead of confusing you.

Sorry, Dave. I had hit reply instead of forwarding it to pd- list(a)iem.kug.ac.at Here's what I had asked about: That helps. Okay, obviously I misunderstood something else. I thought I had read somewhere in the docs that if named something with a $0 in front it will be unique to that patch.

Pack problems
by Jordan J 06 Dec '02

I have included an example patch to show my problem. http://defaced.net/buck/misc/test.pd I have an array named "$0sample". I want to use "getpanel" and "soundfiler" to load a wav file into the array. As you can see, my current method doesn't work. Is there a proper way? Did I miss something here? I hope someone can help and I thank you if you can. -Jordan

Installing Pd with recent versions of Tcl... documantation updated.
by Miller Puckette 06 Dec '02

06 Dec '02

hi all, The documentation for how to install Pd on Mac OSX (on http://www.crca.ucsd.edu/~msp/Pd_documentation/index.htm) was out of date with respect to the new Tcl releases... I've fixed this and uploaded to the HTML documentation, but if you've downloaded Pd for OSX, please use the above link and don't refer to your local HTML documentation for instructions. cheers Miller

help with line~ and commas
by Guilherme Carvalho 04 Dec '02

04 Dec '02

Hello list, I'd like to send a lot of pairs of numbers sequentially to line~, like I can do in Max with one single message. How do I do this in Pd if the messages arriving don't all have the same number of pairs? Also, I have many text files containing those pairs of numbers in numbered lines. I'd like to use maphash to access them in any order, but the thing is they were written for Max's [coll] object, so there's a comma after each index. Any way I could eliminate these before sending the lines to maphash? I figured I could try something with two [textfile]s, but again I stumble on not knowing how many pairs I have in each line (and I don't want to fill every line in maphash with 0's after my last useful pair of numbers). Any suggestions? Is there an object I'm missing in some library? TIA, Guilherme

Hello, Thank you all for your kind messages. I'm sorry to say that it was just begginers panic. The driver cd I had was already old, so I went to the source site and downloaded the drivers for xp. Everything is working fine now. Thank you again for the trouble, João

Alsa/OSS, pd and RME don't like each other
by Orm Finnendahl 03 Dec '02

03 Dec '02

Hi, I'm trying to install pd on an Athlon with Debian 2.4.18-bf2.4 and the RME HDSP. Sound works both with oss-compatible apps (xmms, which autoloads snd-pcm-oss and snd-timer-oss) as well as with alsa apps. PD compiles and works in 0.35-0 and 0.36-10 with the -noaudio option (also midi from the RME card works well). When I try to start with "pd -channels 2 &" the computer freezes completely (it prints out a short message about a OSS blocksize adjustment to 2048). The very same setup works without any problems on my laptop. Any ideas (I could send some logs if someone is interested)? -- Orm

Re: [PD] Problems compiling CVS Gem under SUSE8
by bbogart＠ryerson.ca 03 Dec '02

Hello again, Thanks for the suggestions! I removed all the referenes to yuv from the Gnu Makefile after ./configure and now gem compiles fine. But pix_movie/film does not seem to work... in Guenter's old version pix_movie and pix_film would report what movie file support they have: pix_film:: quicktime4linux support pix_film:: libmpeg3 support And they load my Jpeg Quicktimes fine: GEM: pix_film: Loaded file: /home/bbogart/oracle/work/pd/../../video/air_med.mov with 11682 frames (256x256) allocating But in the new cvs version pix_film reports no such support message and loading the same movie, in the same patch gives: error: GEM: pix_film: '/home/bbogart/oracle/work/pd/../../video/air_med.mov' does not appear to be a supported movie The configure finds mpeg3 and quicktime for linux: checking for quicktime_open in -lquicktime... yes checking for OpenMPEG in -lmpeg... yes checking for mpeg3_open in -lmpeg3... yes And gem compiles fine, it does not report not finding any header files or libs. If there is any other information I can provide to help let me know.
