Pdplay?
by Nicola Bernardini 21 Oct '04

21 Oct '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all, at the SOb project (http://www.soundobject.org) we're writing some really cool physical model objects which we are soon going to package and propose to the pure-data externals repository (they are GNU/GPL). However, we now have a problem that we want to solve soon: we need standalone versions of some demo applications (possibly running griPD etc.) we did. It would be nice to have a sort of MaxPlay type of thing (how about PdPlay?). I have some ideas on how to do it and it could be trivial, and therefore it is very probable that someone has already done it somewhere. If no one has done it, I'll hack up one solution and report back to the list as soon as it is done (it is going to be GNU/GPL anyway :). Thank you in advance for all the help you will want to give. nicb +--------------------------------------------------------------------+ |Nicola Bernardini | |E-mail: nicb(a)centrotemporeale.it | |GPG Fingerprint = 6AE6 AF21 E160 D9B3 396E EBAC 906C CFAE 4D65 D910| |Neither MS-Word nor MS-PowerPoint attachments please: | |http://www.fsf.org/philosophy/no-word-attachments.html | +--------------------------------------------------------------------+ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.0 (GNU/Linux) Comment: Made with pgp4pine 1.75-6 iD8DBQE9mf2qkGzPrk1l2RARAqi/AJ92NXY9HoDWlMbRcu59RkUQNH8E7gCeLU07 +ocbGJWYRzzrrdQO/cG0BcM= =TT6i -----END PGP SIGNATURE-----

Re: [PD-dev] External Manager - Load my Externals
by bbogart＠ryerson.ca 31 May '03

Hey all, I think the PD cvs is the place for the project, but since its not an external where should it go? (should we have a new module for it?) The implimentation will be tcl/tk anyhow, and fully cross-platform. There will be at least one dependancy of the shortcut.dll lib for tcl/tk under windows. I think a home on the PD menu would be a great place for this project, IF PD could load externals and change flags on the fly. (without restarting) without this having it the menu would make little sense, if It is to be integrated into PD without the ability to do this then it would be a kind of splash page, starting up before PD, but then how to deal with loading and saving multiple configuration sets? I think the most elegant solution would be to run it seperate from PD. Mind you I think it would be amazing if PD would load/remove libs and change audio settings on the fly, is this even possible?

External Manager - Load my Externals
by bbogart＠ryerson.ca 31 May '03

31 May '03

Matt and I are getting ramped up for the coding, still designing right now. We're thinking about starting it as a sourceforge project, or should we code it in the PD CVS? Its called LME, and it will have the following functions (on OSX, Linux and Windows): * Turn on and off flags * Add flag options * Add Lib(s) * Remove Lib(s) * Configure (edit conf file) [ where is PD, where to scan for libs, etc.. ] * Load Config Set [ Config sets will be executable without the manager! sh scripts in Linux, .commands in OSX, and shortcuts in Windows ] * Save Config Set * Launch PD with Open Set * Quit * About Feedback? Those interested in collaboration please drop me a line. Ben

Segmented Lines Question
by jon.acker＠easynet.co.uk 30 May '03

30 May '03

1. Where do I send bug reports? 2. Is there any documentation on the PD code? 3 Has anyone done any work on an ability to use segmented connecting lines, ala` Max? If not, what do I need to know, in terms of how the PD code works, in order to implement such a feature? Thanks, Jon Acker. --------------------------------------------------- This mail sent through http://www.easynetdial.co.uk

An Iterator object
by Michael McGonagle 29 May '03

29 May '03

Hello all, I am looking for an object that will create any number of "embedded" iterators. The best analogy would be having a bunch of embedded "for" loops, like this: for (i = i_init; i < i_limit; i += i_inc) for (j = j_init; j < j_limit; j += j_inc) doSomething(); I have created an abstraction that acts as a single loop, and I am using "until" to control the loops iterations. I would like to be able to not use "until" as this forces a restriction of making sure that all operations be performed within the same "time-interval" as all others. I would like to be able to send a single bang to the "top of the loop", and have it output the next set of iterators. For example [iterator 0 10 1 100 1000 100] banging on the iterator would produce the follow excerpt: 0 100 0 200 ...etc 0 1000 1 100 1 200 ...etc Is there an external that does something like this? Thanks, Mike

hmmm, ...after finding the functions "pdtk_canvas_new" and "pdtk_fixwindowmenu" in u_main.tk, I looked at the compile log to see how it's compiled...but couldn't find it! Then I noticed the following: ===================================snip cc -DPD -DUNIX -Wall -W -Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno-switch -O2 -DPD_DEBUG -DMACOSX -I../portaudio_v18/pa_common -I../portaudio_v18/pablio -I../portmidi_osx -Wno-error -DUSEAPI_PORTAUDIO -DPA_BIG_ENDIAN -DINSTALL_PREFIX=\"/usr/local\" -I. -framework Tcl -framework Tk -I/Library/Frameworks/Tk.framework/Versions/Current/Headers -I/Library/Frameworks/Tcl.framework/Versions/Current/Headers -I/Library/Frameworks/Tcl.framework/Versions/8.4/PrivateHeaders -c -o ../obj/t_main.o t_main.c cc: -framework: linker input file unused because linking not done cc: Tcl: linker input file unused because linking not done cc: -framework: linker input file unused because linking not done cc: Tk: linker input file unused because linking not done cc -DPD -DUNIX -Wall -W -Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno-switch -O2 -DPD_DEBUG -DMACOSX -I../portaudio_v18/pa_common -I../portaudio_v18/pablio -I../portmidi_osx -Wno-error -DUSEAPI_PORTAUDIO -DPA_BIG_ENDIAN -DINSTALL_PREFIX=\"/usr/local\" -I. -framework Tcl -framework Tk -I/Library/Frameworks/Tk.framework/Versions/Current/Headers -I/Library/Frameworks/Tcl.framework/Versions/Current/Headers -I/Library/Frameworks/Tcl.framework/Versions/8.4/PrivateHeaders -c -o ../obj/t_tkcmd.o t_tkcmd.c cc: -framework: linker input file unused because linking not done cc: Tcl: linker input file unused because linking not done cc: -framework: linker input file unused because linking not done cc: Tk: linker input file unused because linking not done cd ../obj; libtool -dynamic -o ../bin/pdtcl t_main.o t_tkcmd.o \ /Library/Frameworks/Tk.framework/Versions/Current/Tk \ /Library/Frameworks/Tcl.framework/Versions/Current/Tcl \ /usr/lib/libSystem.B.dylib ===================================snip ...does this mean we aren't correctly linking? Also, I noticed that after doing a "make clean", the pd/bin/pd.tk was still there: so is this correct, or should it be removed and then recompiled? hmmm, jamie

debugging pd/tcl/tk
by tigital 28 May '03

28 May '03

hello, ...I'm probably going to be posting alot on this subject, cuz the bad behavior of pd on OSX with tcl/tk 8.4.2 or 8.4.3 has driven me to start hacking away...I'm learning tcl/tk, and am very confused by how pd handles tcl/tk on osX, but am trying to move forward! BTW, if anyone missed it, pd launches fine and produces all of the expected menus and stuff, but when you open up a patch, all ya get is a blank screen! :-( ...First off, I compiled pd-0.37-test4 with -DPD_DEBUG; however, it only seems to open one little bit of functionality? Along with this, I'm passing the "-d" flag, but this is supposed to be accompanied by a "<n>", which I assume to be a number, but what's the range, and what do the different values differentially produce? ...now I've got pd launching in gdb with a debug build of tcl/tkAqua, but it only sporadically sends out console messages (which is good, I think ;-))...In the following output, I'm opening the first, most basic pd example patch, and then I try to edit it (in the hopes that something can be placed on the canvas): ================================ error parsing RC arguments input device 0, output device 0 pdtk_watchdog pdtk_pd_startup {Pd version 0.37 TEST 4 } pdtk_canvas_new .x1c6170 600 496 +9+22 0 wm title .x1c6170 {01.PART1.hello.pd - /Applications/pd-0.37-test4/doc/2.control.examples} set menu_windowlist {{01.PART1.hello.pd .x1c6170} } pdtk_fixwindowmenu .x1c6170 configure -cursor left_ptr .x1c6170 configure -cursor arrow .x1c6170 configure -cursor left_ptr pdtk_canvas_editval .x1c6170 1 .x1c6170 configure -cursor hand2 .x1c6170.c itemconfigure .x1c6170.t1caa90 -fill blue .x1c6170.c focus .x1c6170.t1caa90 pdtk_text_set .x1c6170.c .x1c6170.t1caa90 { } .x1c6170.c coords .x1c6170.t1caa90R 58 5 90 5 90 25 58 25 58 5 .x1c6170.c select clear .x1c6170.c icursor .x1c6170.t1caa90 0 .x1c6170.c focus .x1c6170.t1caa90 wm title .x1c6170 {01.PART1.hello.pd* - /Applications/pd-0.37-test4/doc/2.control.examples} pdtk_text_set .x1c6170.c .x1c6170.t1caa90 { } .x1c6170.c select clear .x1c6170.c icursor .x1c6170.t1caa90 0 .x1c6170.c focus .x1c6170.t1caa90 selection clear .x1c6170.c .x1c6170.c focus "" pdtk_text_set .x1c6170.c .x1c6170.t1caa90 { } .x1c6170.c itemconfigure .x1c6170.t1caa90 -fill black pdtk_canvas_editval .x1c6170 0 pdtk_check {This window has been modified.

As an aside, the linefeeds are spit out when the program is idle (I think this used to be listed as "pd.watchdog"): what is the advantage of this behavior? thanks, jamie

Re: [PD] fluid~, shabby~, shaffy~ segfaults

Hallo, [I'm slowly taking this over to pd-dev...] guenter geiger hat gesagt: // guenter geiger wrote: > Strangly enough the last time we did latency tests using the > OSS layer for ALSA, we discovered that the OSS layer showed > by far better performance than the ALSA implementation. > (Because it uses blocking I/O, which gives better time resolution) > So there should be no reason not to run pd under OSS until > we have time to fix the ALSA I/O (which should be supported > by portaudio actually) I couldn't get Pd and OSS-emu work together with my M-Audio Quattro in 4-channel mode. :( That's my personal reason. To use the Quattro this way some .asoundrc magic is needed, and at least I couldn't transfer this to OSS-devices. Regarding portaudio: I came a little bit farther along in activating the ALSA interface of Portaudio in Pd. I replaced all portaudio files except the pablio directory with current PA-cvs. I then had to edit the Makefiles by hand, replace PA_USEAPI_OSS -> PA...ALSA, add "-lasound" to the final linking and remove -Werror. After that Pd compiled and ran, but it couldn't open the ALSA sound devices. The error message is: ALSA lib pcm_hw.c:1078:(snd_pcm_hw_open) open /dev/snd/pcmC2D0c failed: No such file or directory ALSA lib pcm_hw.c:1078:(snd_pcm_hw_open) open /dev/snd/pcmC2D0p failed: No such file or directory ^- this also happens with the test programs and might be harmless input device 0, output device 0 nchan 2, flags 3, bufs 8, framesperbuf 256 ALSA call at line 381 succeeded ALSA call at line 388 succeeded ALSA format: 10 ALSA call at line 423 succeeded ALSA call at line 426 succeeded Error executing ALSA call, line 429 Error number -9993 occured opening portaudio stream Error message: Illegal combination of I/O devices I guess, that maybe my main card, the M-Audio Audiophile is creating this error. It is a stereo card, but the chipset (ICE1712) has 10 in- and 12 out-channels. The line numbers above refer to pa_linux_alsa.c where it fails at line 429, which says: /* ... set the number of channels */ ENSURE( snd_pcm_hw_params_set_channels( stream, hw_params, channels ) ); The three alsa-enabled pa_test programs do work, for example patest_sine, even when compiled with Pd's pabilo changes. Maybe this rings a bell with someone? ciao -- Frank Barknecht _ ______footils.org__

pd0.37 test4 (win) P4 optimized
by Olaf Matthes 26 May '03

26 May '03

I just uploaded a P4 optimized version of pd0.37 test4 (also includes latest portaudio v19 snapshot) to http://www.akustische-kunst.org/puredata/experimental/pd0.37-test4-win-P4.z… Maybe it is of some use for somebody... Olaf

pd save & threads
by Tom Schouten 19 May '03

19 May '03

hi all, i have a question about what happens when a pd document is saved. more specificly, can it be that some clocks get reset or some messages dropped? i'm experiencing some deadlock problems that only occur when ctrl-s is pressed. this is highly probably a bug in my own code, but since really don't understand what's going wrong, i thought maybe the save command doesn't just "stop time". any thoughts? tom
