Nothing shows up in pd main window
by Batuhan Bozkurt 30 Aug '07

30 Aug '07

Hello, I'm having an issue with my Pd version 0.39.3-extended-rc5 installation in ubuntu feisty fawn. I was having no problems when suddenly the pd icon on my desktop refused to launch pd properly. A blank pd window shows up: http://www.batuhanbozkurt.com/stuff/pdblank.png Launching pd by pressing alt+f2 and writing "pd" yields to the same result. However if I launch pd from terminal by writing "pd", it launches fine. But the menu fonts are garbled(which is the case in all tcl/tk applications-not pd spesific). http://www.batuhanbozkurt.com/stuff/pdfonts.png I think I'm having a problem with Tcl/Tk right? Any suggestions for this? Thanks. Batuhan

puredocumentation
by marius schebella 30 Aug '07

hi, this is the start for the puredocumentation wiki. for all who didn't follow the discussions during the pdconv, here is the latest: some people agreed on building a media wiki for all documentation beyond the pd help patches. some time ago there was the puredatabase, but that is quite dead now. so the idea is, to reanimate something similar, but with the possibility for everyone to commit to it. maybe not everyone but if 5-10% of users help contributing, then I think the project will be successful. one of the reasons why this should be done, is that very often pd users look for a certain feature or object, but don't know the name exactly and need a good search engine. so... the puredocumentation (in planning state) will cover externals and "stable" abstractions. (abstractions that are maintained kind of like externals) additionally to the "wiki for objects" there will be the section for the tutorials, manuals and faq, and hopefully you will be able to type in your search string after "How do I: " and get the right objects, examples and tutorials. My estimation is, that there are more than 3000 objects atm. so for the beginning the tricky part is to build all the basic object pages from the existing documentation (mainly help patches). here is, what I think should be the content of every object page: *objectname* the string name (for example "plus" for "+") of the object/external *opt other name* = abbreviation, +,.. *helpfilename* (can be different than object name), *description* = short description *libraryinfo* purepd,GEM,cyclone... + author + licence *arguments* *inlets/outlets* *examples* what this object is for... that's where you can be creative! *see also* / similar objects *tags* like audio/dsp, math, MIDI, something like a categorization. I want to use python to extract as much information as possible from the help-patches into one big textfile (csv style) from which we can create the wikipages. I hope to get the developers involved in correcting the cvs-textfile before the basic pages are created). this has to be done per library, and I am still trying to figure out, how to do this in detail. for example some help patches have some description in the top letmost corner. so a python script should be able to find that information and put it into the "description" field. there will be an irc session on sep 11 with all the people working on the project. so maybe if you want to join or have suggestions on how to get this done, feel free to respond. addtitional documentation work that probably will also be done: improving help patches by switching to a nice pddp format. creating online video tutorials, or recordings of workshops. one last point: If you know of a school/university or teaching center that would like to get involved (for example by putting pd classes on their schedule or paying people do some documentation work) that would also help the project to be successful... so far. thanks for reading through that all! marius. # this file will look slightly different for every library # write everything into a database like format... (NOT YET!!!) # OBJECTNAME | OPT OTHER NAME | HELPFILE-NAME | DESCRIPTION | TAGS | LIBRARYINFO | ARGUMENTS | INLETS/OUTLETS | EXAMPLES | SEE ALSO # objectname is the string name (for example "plus" for "+") # opt other name = abbreviation, +, # helpfilename (can be different than object name), # description = short description # libraryinfo: purepd or GEM + author + licence # arguments # inlets/outlets # examples : what this object is for... # see also/similar objects # junk # # use X coordinate to sort comments??? import re import os print 'searching all files for comments' searchPattern = "#X text \d+ \d+ " # search for comments replacePattern = searchPattern # what can be deleted of the comments deleteNLPattern = r'\r' # delete cr fileExtension = ".*[.]pd$" # files to look for separator = "|" # separate colomns separator2 = "___" # separate junk fileTo = "test_to.txt" p = re.compile(searchPattern) rep = re.compile(replacePattern) nldel = re.compile(deleteNLPattern) fe = re.compile(fileExtension) f2 = open(fileTo, "w") for fileName in os.listdir("."): m = fe.search(fileName) if m: # only if is it a pd-file f = open(fileName, "r") first = 1 # suppose the first entry is the description for line in f: m = p.search(line) # search in line for pd-comment pattern if m: line = nldel.sub("",line) if first == 1: # help needed! how to sort other than by appearance? write to array? f2.write("\n" + fileName + separator) #need \n for every file but the first. newText = rep.sub("",line) # this should delete the trailing pattern f2.write(newText[:-1]) # this writes without closing nl f2.write(separator) first = 0 else: newText = rep.sub("",line) f2.write(newText[:-1]) f2.write(separator2) f.close() f2.close() #done...

DAWN2007 in Limerick, Ireland
by Mikael Fernstrom 29 Aug '07

29 Aug '07

The reason I'm posting this on the pd list is that many, if not most, of our students that have audio in their work use pd ;-) Sorry for any cross-postings. /Mikael --- DAWN’07 - DIGITAL ARTS WEEK NOW 2007 at UL, 3rd o 7th of September 2007 For the eight year in a row, the University of Limerick offers an exhibition and concert of Masters’ student work. It’s the students from the Masters programmes in Music Technology and Interactive Media that showcase their end-of-year work. The exhibition shows technology, media and music that may be the start of tomorrow’s revolution. With the freedom given to the students to envisage where current trends are going and what is possible with the latest computer hardware and software, we have the opportunity to see demonstrations and examples of what a not too distant future has to offer. The Computer Science and Information Systems Department at the University of Limerick runs both programmes. What makes UL’s programmes so special is that they recognise the importance of interdisciplinary work, bridging traditional divisions between arts and science. The faculty at UL teaching on the two programmes are highly enthusiastic about the exhbition. For example: Jürgen Simpson, the Course Director of the Music Technology programme said “This is the one of the few programmes in Ireland where you can get a Masters degree in electroacoustic music composition. Some students also choose a scientific approach and do work in areas such as musical user interfaces, sound synthesis software and audio processing – which we know are increasingly important with the evolution of music and media on the Internet”. Mikael Fernström, the Course Director in Interactive Media enthusiastically commented that “Over the last few years we have seen our students research and develop some extremely novel ideas and technologies. Some of our past students have started companies based on their ideas, others have become specialists or teachers in both technology and digital art. I have a strong feeling that many of this year’s projects may follow the same successful path.“ UL also has two undergraduate programmes, in Digital Media Design and in Music Media and Performance Technology. The Computer Science department has built a new laboratory with state-of-the-art digital music and media equipment and software to facilitate the new courses that will continue to strengthen UL’s position in an increasingly digital world. Admission to the exhibition and to the concert is free. Official opening: 18:00, 3rd of September, Ground floor atrium, Foundation Building. Concert: 20:00, Performance Art Centre, Foundation Building Exhibition: 3rd to 7th of September, 10:00-17:00, Shuman Building For details about the works, see http://www.csis.ul.ie/imedia/dawn07/ For more information you can email mikael.fernstrom(a)ul.ie, phone: 086-8188079, or jurgen.simpson(a)ul.ie.

When i record a [pix_video] with it "with the hand" and a filename " file video.mov" it's ok. (but "dialog" appears from time to time .. ) But, when I try to record several videos dynamically with [file $1.mov] .... crash... does somebody have some councils? by advance thank you! i post my test patch... maybe..or probably it's a error to me ! _____________________________________________________________________________ Ne gardez plus qu'une seule adresse mail !

looking for explanation about deprecated [matrix] and [matrix~] objects
by Hector Centeno 29 Aug '07

29 Aug '07

Hello, I've been searching the documentation and the web for the manual pages of the, already deprecated, [matrix] and [matrix~] objects. I was wondering if anyone could quickly tell me what are they for (matrix multiplication, I think), what goes in and out the inlets and outlets, and the init parameters. Or maybe a link to a manual page. Thank you, Hector

cannot get Motu Ultralite to use multichannel input in Windows (neither ASIO nor MMIO)
by matteo sisti sette 29 Aug '07

29 Aug '07

Hi list, I have a Motu Ultralite FireWire external audio interface, and I need to use 4 channel input and 2 channel output, in Windows XP. I have tried everything but either I cannot get 4 input, or I cannot get the output. With PD, of course. Here are more details. This card is supposed to have: - 8 analog input channels called Analog (1 to 8) - 2(?) digital spdif input channels called "SPDIF" - 2 virtual input channels called Mix which I don't know whether it is a mixdown of inputs or of outputs but I don't care; and: -8 analog output channels called Analog (1 to 8) -2 more analog output channels called Main Outs -2 more analog output channels called Phones -2(?) digital spdif output channels called SPDIF If I work with MMIO, the list of devices I can select for input are: ** MMIO INPUT DEVICES ** - MOTU Analog - Realtek HD audio input - MOTU Mix1 - MOTU SPDIF ** MMIO OUTPUT DEVICES ** - MOTU Main Outs - Realtek HD audio output - MOTU Phones - MOTU Analog - MOTU SPDIF where Realtek HD is my integrated internal audio card. They are listed just as I wrote them: with no channel numbers. So, by using "use multiple devices", I have no way of selecting Analog 1,2 AND Analog 3,4 as inputs. And if I don't activate "use multiple devices" and I write "4" as the number of input channels, it doesn't work: it simply uses MOTU Analog 1 and 2 as the first two channels, and Realtek inputs as the 3rd and 4th channel. So, I tried with ASIO. If I select ASIO, I get the following device lists: ** ASIO INPUT DEVICES ** - (0) Window sound mapper (or something like that: I'm translating from Spanish) - (0) MOTU Analog - (0) Realtek HD audio input - (0) MOTU Mix1 - (0) MOTU SPDIF - (1) MOTU Audio ASIO ** ASIO OUTPUT DEVICES ** - (0) Window sound mapper (same as above) - (0) MOTU Main Outs - (0) Realtek HD audio output - (0) MOTU Phones - (0) MOTU Analog - (0) MOTU SPDIF - (1) MOTU Audio ASIO Now, there's NO WAY of getting both 4 inputs and 2 outputs. Wherever I try to use 4 input channels, I get no input and no output at all. Here are some combinations of settings I tried, and the results I get: ** A ** INPUT: (1) MOTU Audio ASIO - Channels: 4 OUTPUT: (1) MOTU Audio ASIO - Channels: 2 RESULT: no input and no output at all! ** B ** INPUT: (1) MOTU Audio ASIO - Channels: 2 OUTPUT: (1) MOTU AUDIO ASIO - Channels: 2 RESULT: 2 input channels work, but no output at all. ** C ** INPUT: (0) MOTU Analog - Channels: 4 OUTPUT: (0) MOTU Main Outs - Channels: 2 RESULT: no input and output at all ** D ** INPUT: (0) MOTU Analog - Channels: 2 OUTPUT: (0) MOTU Main Outs - Channels: 2 RESULT: 2 in 2 out working. This is the best I can get, and this is the same as MMIO, but I need 4 in. ** E ** INPUT: (0) MOTU Analog - Channels: 4 OUTPUT: (0) MOTU Main Outs - Channels: 4 RESULT: no input and output at all (tried this last one just in case the number of in and out channels had to be the same... pure superstition) Etcetera. I even tried insane combinations. No way. Has anyone ever managed to use 4 in / 2 out (also interested in 4 in / 4 out) with this sound card in Windows with PD? How??? And what about other cards? Is this a general issue with ASIO, or specific to this card? Is it possible at all with MMIO to get 4 in /2 out or 4 in / 4 out? I am really desperate. I can even change sound card if I know it will work. Thank you in advance, Matteo

vbap and matrix external
by Hector Centeno 29 Aug '07

29 Aug '07

Hi, I'm trying to get vbap working using Linux Fedora 7/Planet CCRMA. I'm using the Planet's packages which are version 0.39.2. First I found vbap in two different places: /usr/lib/pd/extra/vbap /usr/lib/pd/extra/ggee What is the difference? So I tried with the vbap directory. When trying to load the demo I struggled with finding matrix and matrix~. There are externals named like this in different directories: /usr/lib/pd/extra/cyclone/matrix~.pd_linux /usr/lib/pd/extra/flatspace/matrix.pd_linux /usr/lib/pd/extra/flatspace/matrix~.pd_linux /usr/lib/pd/extra/creb/matrix~.pd_linux Does anyone know which ones are the right ones to use? I managed to get the demo loaded and running using the matrix in flatspace and matrix~ in cyclone but I can't get any audio output. I'm fairly new to PD so some help would be appreciated. Cheers, Hector
