PD externals/extras/OSC and RT and JACK
by Ken Restivo 02 Sep '07

02 Sep '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've started playing with PD, and so far I am really enjoying it. I'm using the Debian Sid package (0.40.2-2) on an amd64 (Intel Core 2 Duo) system, using JACK. Everything seems to work perfectly. In fact, PD is the only music language that works at all out-of-the-box on this 64-bit hardware. So far I'm finding what I need in the docs and via Google. A couple things still evade me though: 1) PD doesn't seem to run in realtime mode when using the -rt flag. The docs say that this requires "root mode", but that doesn't make any sense. JACK and dozens of softsynths work in RT mode as a non-root user, using PAM (new method) or capabilities module. But I'm not sure how to get PD to do that. 2) I'm confused by the Debian puredata package versus pd-externals and pd-extended. I found an ancient package of pd-externals, but it seems that some (vu, for example) of those are now in the main puredata package. However others (cheby~, for example) aren't. The only one I really need is the ladspa~ external, but I'm not sure where to find it or how to install it without clobbering or interfering with the main puredata package. 3) I found the source to OSCx on SourceForge, but it looks ancient (i.e. from 2002), which includes it's own statically-linked (and very old) version of libosc. Is that really the latest release? I'm thrilled that PD makes working with MIDI so easy, but I am going to want to use OSC too. 4) I can't seem to figure out how to save audio settings such that pd starts up JACK and ALSA MIDI upon startup. Every time I start it, I have to manually go into the Media menu, and select JACK, and tell it how many audio ports (it doesn't remember), and select the ALSA-MIDI dialog box and tell it how many MIDI ports (it *does* remember that), before it opens the ALSA port. I'd like both to happen automatically at startup. I'm using "pd -rt -jack -alsamidi" but it seems to disregard those. 5) I was able to locate and run the flext and py sources (separately from all of the above), and build and install them. So far PD has been straightforward enough that I haven't had any need to mess around with embedded python, but it was nice to be able to build an external with no trouble. Thanks! - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFG014Oe8HF+6xeOIcRAlZGAJ9FVWleDrsb7cTmZph5XQs9b9DVUQCg5nlW cLDpVhNI5SdCfjhRvaJ6hkk= =viub -----END PGP SIGNATURE-----

compile partconv~ for intelmac
by Luigi Rensinghoff 30 Aug '07

30 Aug '07

Hi Developers, in particular Inte-Mac Users ;-) well probably i shouldnt even try, but i would like to test partconv on an intel mac. So i am trying to compile it myself, which, well.......i dont really have enough background knowledge. Maybe someone wants to help me anyway or has a pd_darwin version, to share... So i installed fftw3 with fink because it was missing, but now i encounter the next "stop" ---- gigimacbook:/Applications/PureData/Added_abs/partconv~-0.2 root# make pd_darwin cc -DPD -O3 -funroll-loops -fomit-frame-pointer -Wall -W -Wno-long- double -Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno- switch -fno-common -I/Applications/PureData/pd-0.39-2/src -o partconv~.o -c partconv~.c cc -bundle -undefined suppress -flat_namespace -o partconv~.pd_darwin partconv~.o /usr/local/lib/libfftw3f.a -lc -lm i686-apple-darwin8-gcc-4.0.1: /usr/local/lib/libfftw3f.a: No such file or directory make: *** [partconv~.pd_darwin] Error 1 ... any idea ???

JACK transport and syncing
by Ken Restivo 29 Aug '07

29 Aug '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 After Googling around some, I haven't found anything that looks like it allows PD to sync to JACK transport. In particular, I'd like metro object to be synced with JACK. Worst case, I could use MTC, if there's a MTC-sync'ed metro object somewhere for PD. Finally, what do y'all use for Googling for PD-related stuff? Googling for "pure::data" doesn't always work (are the colons special characters in Google?), "pd" sometimes works, the words "pure data" are too common, and "pure.data" seems best so far. I guess I'm looking for a statistically-improbable phrase to filter for search results specific to PD. - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFG1Gwge8HF+6xeOIcRAmbgAKCDSQ7ESONTQqTxGdwNxe7DLR3SXwCg/1CX hEV/Uze4X4cYHWADl8uHLf0= =Oag0 -----END PGP SIGNATURE-----

problem opening .pat files
by Andrew May 27 Aug '07

27 Aug '07

I'm able to open Max .pat files in pd-extended 0.38.4; but not in pd 0.39.2, pd-extended 0.39-3 (including the cyclone library), or pd 0.40-2. There's no error message: the dialog box accepts the request, then nothing happens. Is this a known issue? Might I be doing something wrong? Andrew

fix for pd compilation on OpenSUSE (HZ and sysconf())

It seems OpenSUSE is following this document: http://www.opengroup.org/onlinepubs/009695399/functions/sysconf.html which makes some sense regarding portability of binaries to systems other than the one they were compiled on. Since sysconf() is a function, it might be better to cache HZ in a variable together with the above "quick fix" #define, given that it is guaranteed to remain unchanged throughout the lifetime of the process.

does pd use dual buffer approach ?
by Sergei Steshenko 19 Aug '07

19 Aug '07

Hello All, I have a very basic question regarding pd - does it use dual buffer approach ? That is, suppose I'm going to use a FIR (FFT, for example) with long (several seconds) processing time (latency), and there is enough CPU performance to do processing in real time. Still, if I want to hear uninterrupted sound, the sound card, having, say, a buffer of 4096 samples has to be fed new data much more often - with 44.1KHz sampling frequency it has to be fed about 11 times per second. So, a possible solution is to have to buffers - while one of them is waiting for the new data from the FIR, the other piece by piece feeds data to soundcard, and when the feeding buffer is empty, the buffers are swapped. So, how does pd deal with long latencies like in the case described above - does it use dual buffer approach in order to have uninterrupted sound ? Thanks, Sergei.

problems building FFTW-enabled pd
by Sergei Steshenko 18 Aug '07

18 Aug '07

Hello All, I'm trying to build pd-0.40-2 in the framework of my AppsFromScratch. For starters, 'gcc' complains about 'logn' on line #44 and 'inverse' on on line #47 of 'pd-0.40-2/src/d_fft_fftw.c' file: 42 static fftw_plan fftw_getplan(int n, int dir) 43 { 44 logn = ilog2(n); 45 if (logn < MINFFT || logn > MAXFFT) 46 return (0); 47 int indx = 2*(logn-MINFFT) + inverse); 48 if (!fftw_pvec[indx] 49 fftw_pvec[indx] = fftw_create_plan(N, dir, FFTW_MEASURE); 50 return (fftw_pvec[indx]); 51 } - the two variables are undeclared, so 'gcc' is correct. The situation is the same in build/pd-0.40-3/src/d_fft_fftw.c . What should I do in order to build FFTW-enabled 'pd' ? In case anybody is interested, here's how I've run 'configure': " cd /maxtor5/sergei/AppsFromScratchWD/build/pd-0.40-2/src; PATH=/maxtor5/sergei/AppsFromScratchWD/install/autoconf-2.61/bin:/maxtor5/sergei/AppsFromScratchWD/install/autogen-5.8.7/bin:/maxtor5/sergei/AppsFromScratchWD/install/bash-3.0/bin:/maxtor5/sergei/AppsFromScratchWD/install/dejagnu-1.4.4/bin:/maxtor5/sergei/AppsFromScratchWD/install/expect-5.44.1/bin:/maxtor5/sergei/AppsFromScratchWD/install/gcc-3.4.6/bin:/maxtor5/sergei/AppsFromScratchWD/install/gperf-3.0.2/bin:/maxtor5/sergei/AppsFromScratchWD/install/guile-1.8.1/bin:/maxtor5/sergei/AppsFromScratchWD/install/jack-audio-connection-kit-0.103.0/bin:/maxtor5/sergei/AppsFromScratchWD/install/libavc1394-0.5.3/bin:/maxtor5/sergei/AppsFromScratchWD/install/libiec61883-1.1.0/bin:/maxtor5/sergei/AppsFromScratchWD/install/libraw1394-1.2.1/bin:/maxtor5/sergei/AppsFromScratchWD/install/libsndfile-1.0.17/bin:/maxtor5/sergei/AppsFromScratchWD/install/libtool-1.5.24/bin:/maxtor5/sergei/AppsFromScratchWD/install/libxml2-2.6.26/bin:/maxtor5/sergei/AppsFromScratchWD/install/m4-1.4.10/bin:/max tor5/sergei/AppsFromScratchWD/install/make-3.80/bin:/maxtor5/sergei/AppsFromScratchWD/install/ncurses-5.6/bin:/maxtor5/sergei/AppsFromScratchWD/install/tcl-8.4.15/bin:/maxtor5/sergei/AppsFromScratchWD/install/texinfo-4.9/bin:/maxtor5/sergei/AppsFromScratchWD/install/tk-8.4.15/bin:/maxtor5/sergei/AppsFromScratchWD/install/pkg-config-0.21/bin:/opt/kde3/bin:/home/sergei/bin:/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin:/usr/lib/jvm/jre/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/home/sergei/bin;

[ pure-data-Bugs-1776553 ] Message boxes seem to behave inconsistently

Category: puredata Group: None >Status: Closed >Resolution: Invalid Priority: 5 Private: No Submitted By: r jacobs (rnjacobs) Assigned to: Nobody/Anonymous (nobody) Summary: Message boxes seem to behave inconsistently Initial Comment: I don't know whether this is an actual bug, but it is a strange inconsistency. In using PD 0.40-2 in the Debian archive, the attached patch (three message boxes, containing a list "1 2 3", an anything "a b c", and "$1 $2") produces the output r: 1 2 3 p: 1 2 r: a b c p: b c I assume the reason the last line is "b c" instead of "a b" is because the message box sees that the input is an anything and interprets "a" as a type. But "a" isn't a type, so there is no way to get the first element of an anything using a message box (yes, i could use an unpack, so there's definitely workarounds). Is this a bug? Thank you! ---------------------------------------------------------------------- >Comment By: Frank Barknecht (fbar) Date: 2007-08-18 20:13 Message: Logged In: YES user_id=569446 Originator: NO As m. sistisette perfectly explained, it's not a bug, but a feature. You may also want to read this page: http://puredata.info/dev/PdMessages which has an explanation of the "types" of messages, Pd can use.

In the message [a b c(, "a" is the "message identifier" (not sure the terminology I'm using is correct)... that's what you call the "type", but it need not be a type (such as symbol float or list). So b and c are the first and second arguments. "a" is not an argument. If you want to get the first element (i.e. the identifier) you need to convert the anything message into a list, so that the identifier is converted into the first argument, i.e.: [a b c( | [list] <-- this outputs "list a b c" | [$1 $2( Hope this helped. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478070&aid=1776553&group_…

Something wrong with Sourceforge?
by Frank Barknecht 18 Aug '07

18 Aug '07

Hallo, I cannot open pages on Sourceforge ATM, http://sf.net is more or less empty and just has some HTML in it, title is suspicious, too: "Exiting with error". The same happens on slashdot, so I guess, something's broken at OSDN. Does anyone know anything more? Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__
