import-disabled list-abs
by Luka Princic // Nova deViator 14 Feb '11

14 Feb '11

hi, i'm working on an abstraction that contains an object from a library for which i need to create [import nusmuk] in order to use ([granulator]). when i create a new instance of that abstraction, pd console reports import-disabled list-abs ... couldn't create could someone explain what this error means? is it deprecated to use [import] and i should rather use syntax like [nusmuk/granulator] ? l. -- sujet est machinique!

pdlib / pdtest
by patrick 07 Feb '11

07 Feb '11

hi everyone, is the samples/pdtest supposed to output sound or only text: print: 3 noteon: 0 112 0 looking at test.pd i should hear an osc @ 400hz, but i do not. the python version is working (python echo.py) i can hear myself with a delay. my goal is to use it in my application (C++ with a wxwidgets gui). should it be possible to embed libpd into a C++ application (windows, mac, linux)? if yes, i will not need to worry about audio driver (libpd will take care of choosing the right driver for the platform)? pat

Re: [PD] libraries in Pd-extended 0.43
by Hans-Christoph Steiner 16 Jan '11

16 Jan '11

A long standing complaint of Pd-extended is that it is hard to know what all is in it and how it got there. Plus the old build system is a bug ugly whack thing that is not understandable We've made the library template and that's working well so far. We Here are some concrete steps to take on to help with this effort, either as the maintainer of a library, or just where you can help: - add a page to the the downloads page http://puredata.info/community/projects/software/ (this will become http://puredata.info/downloads soon). - add releases to the download page - improving documentation - making a Debian package - taking a pure:dyne package and getting it ready for submission to Debian - test releases - update the code in the Pd-extended release branch, once that is in place There is some developing documentation here, its not cast in stone yet: http://puredata.info/docs/AddingYourProjectToDownloads http://puredata.info/docs/LibrariesInPdExtended http://puredata.info/docs/developer/GettingIntoPdextended There is a library template too. People aren't required to use this, but it makes things a lot easier IMHO: http://puredata.info/docs/developer/LibraryTemplate .hc On Mon, Dec 13, 2010 at 6:05 PM, Hans-Christoph Steiner <hans(a)at.or.at> wrote: Hey Alan, Thanks for the offer!

hello just built gridflow on maverick. ./configure tells me: libv4l1 ---> found libv4l2 ---> found etc (everything except osx related is found), it builds fine, but if try the examples, opening [#camera], selecting libv4l2 and then my video device (video0) gives me this error: error: [#io.v4l2 in /dev/video0 1]: this [#io.v4l2] wasn't compiled with libv4l2 support #io.v4l2 in /dev/video0 1 ... couldn't create print: symbol v4l2 error: [gf/not_open]: not open if I choose ...v4l2 I get: error: ioctl VIDIOC_G_FREQUENCY: Invalid argument I get the same errors with both pd-extended 0.42.5 and latest pd from git. thanks for your help, _y

The (not) doppler distortion (was: overdriven speaker)
by - 16 Jan '11

16 Jan '11

Martin Schied found a interesting distortion. Nothing new I guess but worth some analysation. haut-parleur-doppler.pd is the original file from Martin, the other one my variation to get a better glimpse at it. If you like sunn o))) or similar you might like it. But I suggest you first look at how it behaves without feedback. >> Sounds really cool with a guitar and with high gain (around 50). What's nice is the change in the spectrum depending on the volume of the input. > > But all waveshapers also do change the spectrum according to the volume (except those that are linear, which basically means those waveshapers that are configured to do nothing.) This is wrong for this distortion. And that again is what is interesting about it. The distortion depends only on the travel speed of the vd~. But if you multiply the signal with a gain you also change the velocity by that amount. A negative velocity (down to a delay of 0) means a pitchshift upwards. While a positive velocity means a downshift. At a velocity of 1ms/ms is the turning point, for faster modulation the signal is played in reverse. A reflection at 0Hz, which is basically the same as a Nyquist reflection. The parallel up/downshifting leads to a chaotic spectrum change. With a speed of .7 ms/ms we have at the same time the signal with 30% and 170% playback speed. Which clearly has no relation to the original pitch and no harmonic relation left. This is only intensified through the reversed playback and the constant velocity change. While typical (soft-)clipping only generates harmonics related to the fundamental. The more I think about it the more fascinated I am that this results in something interesting to the ear. So what we have here is some kind of natural asymmetrical distortion. As the velocity is the important factor it has the interesting property of being frequency (and amplitude) dependant! A modulation frequency (amplitude) of *2 results in a velocity of *2. This means: the higher the input frequency (or amplitude) the harsher the distortion. If wanted this can be compensated for with a simple lop~, who has a rolloff of -6 Db/dec or in rms: a frequency increase of *2 means a amplitude reduction to 0.5. So every frequency above the cut-off-frequency has now (almost) the same impact on the distortion. Please correct me if I'm wrong somewhere. And have fun. -

window-switching on OSX?
by Damian Stewart 15 Jan '11

15 Jan '11

How do I switch between open windows on OSX using the keyboard? On PC I used to be able to Ctrl-Tab. The OSX equivalent of that is Apple-`, but it doesn't do anything; Apple-Tab on OSX switches applications, which doesn't help either. cheers D -- Damian Stewart +64 27 305 4107 f r e y live music with machines http://www.frey.co.nz http://www.myspace.com/freyed

PD L2Ork 20101229 snapshot now available
by Ivica Ico Bukvic 02 Jan '11

02 Jan '11

Please excuse cross-posting. Dear friends and fellow FOSS enthusiasts, It is my great pleasure to share with the community a belated Holiday present :-) in a form of latest snapshot of L2Ork iteration of Pure-Data. Better than ever, the latest version comes with the following improvements: *implemented apply undo for array properties and partially implemented apply undo for graph-on-parent object properties (does not apply to abstractions or top-level windows currently until I figure out how to address the indexing of toplevel windows inside the glist as well as how to address to which window such an undo belongs). *properties are disabled when right-clicking on an abstraction as modifying its settings externally does not make sense when one does not see the actual contents inside it. So, to edit the properties of an abstraction, one has to open the actual abstraction. *fixed how new arrays are created so that they always fit within the specified boundaries. Please note arrays that have been already created in prior patches remain untouched in terms of graph auto-resizing (legacy code is provided in g_editor.c canvas_vis that deals with this if anyone wishes to convert their arrays but is incomplete in that it assumes all arrays require resizing--this is however unnecessary as simple recreation of said arrays or manual readjustment of their settings ought to do the trick. -This feature needs further testing--feedback is most appreciated. *fixed how arrays deal with moving array points via mouse by restricting them within the array bounds--this should work for all gui-driven array operations, while array alterations via snapshots and other external ways of manipulating arrays remain unbound so as to allow for traditional data-flow debugging--this may change down the road in part due to introduction of the magicGlass option and in part due to belief that data monitoring should only report ranges specified by the graph. -This feature needs further testing--feedback is most appreciated. *added new feature for arrays where they report a bang through the <arrayname>_changed send (if one is provided) whenever they have been altered by a mouse click'n'drag--this in conjunction with array graph auto-resizing makes arrays formidable alternatives for multisliders. -This feature needs further testing--feedback is most appreciated. *when an array subpatch is opened and resized, the array automatically now resizes to properly fill the window. -This feature needs further testing--feedback is most appreciated. *fixed where array was not visible after reopening the patch if any of its points touched upon y graph limits. *fixed couple of segfaults caused by gridflow incompatibility--more problems remain with gridflow library compatibility, likely due to widgetbehavior and possibly also magicGlass incompatibility. Further investigation is necessary. *fixed memory leak in the disis_phasor~ external where the destructor was never properly called and updated its documentation (available in the l2ork_addons package). *fixed highlighting of signal nlets where nlet would revert to non-signal appearance after being highlighted/connected. *reintroduced array listview (this was a regression in respect to pd-extended). *improved appearance of the array listview. *fixed a few broken links in the pddp documentation and added new l2ork-specific array features to the pddp documentation. Latest snapshot is available from the usual place: http://l2ork.music.vt.edu/main/?page_id=56 Complete changelog since 11/25/2010 is available here: http://l2ork.music.vt.edu/data/pd/Changelog Happy belated Holidays! Best wishes, Ico

other ideas for inlet/outlet in complex patches
by ronni montoya 01 Jan '11

01 Jan '11

Hi dear list, imagine i have a patch with 20 nested subpatches , one subpatch inside another 20 times. At sometime i would like to connect one subpatch with the main patch , lets say the 15th. I dont want to create 15 pairs of inlet/outlet and connect one subpatch to its parent until arrive to the main patch. This seems a little bit silly, i was wondering if its possible to connect directly any subpatch with the main patch withouth doing that? If not dont you think having such mechanism would be a good idea to implement? what do you think? thanks R.

question about pd tutorial
by Aaron L. 01 Jan '11

01 Jan '11

Hi. I'm trying to do the tutorial near the bottom of this page (the one titled "3.1.2.2.3 Processing adc-input"): http://www.pd-tutorial.com/english/ch03.html ....which mentions "Say something into a microphone and play it back at a changed volume" I'm not totally sure how this would work, however. I can indeed see the signal on my mic when talking into it (i.e. it gets hotter the louder I talk) but using the slider doesn't do anything to the volume. At least from what I can tell anyway. Am I missing something here? Could it be my audio setup (I'm on Ubuntu 8.04 using ALSA)? Should I be hearing the volume increase when sliding up and volume decreasing when sliding down? Because I'm not. I'm hearing my voice in my headphones. It just doesn't change in regards to the slider's position. Thanks for any input. -Aaron

Also the debug log shown that search under multiple paths (none included /usr/lib/pdextended/extra/mrpeach) was failed for that functions. Looks like http://www.mail-archive.com/pd-dev@iem.at/msg04901.html, but checks more paths. udpreceive 8080 ... couldn't create tried /usr/local/lib/pd-externals/sprintf.l_ia64 and failed tried /usr/lib/pd-extended/extra/sprintf.l_ia64 and failed tried /usr/local/lib/pd-externals/sprintf.pd_linux and failed tried /usr/lib/pd-extended/extra/sprintf.pd_linux and failed tried /usr/local/lib/pd-externals/sprintf/sprintf.l_ia64 and failed tried /usr/lib/pd-extended/extra/sprintf/sprintf.l_ia64 and failed tried /usr/local/lib/pd-externals/sprintf/sprintf.pd_linux and failed tried /usr/lib/pd-extended/extra/sprintf/sprintf.pd_linux and failed tried /usr/local/lib/pd-externals/sprintf.pd and failed tried /usr/lib/pd-extended/extra/sprintf.pd and failed tried /usr/local/lib/pd-externals/sprintf.pat and failed tried /usr/lib/pd-extended/extra/sprintf.pat and failed sprintf connect %s 8080 ... couldn't create tried /usr/local/lib/pd-externals/mrpeach.l_ia64 and failed tried /usr/lib/pd-extended/extra/mrpeach.l_ia64 and failed tried /usr/local/lib/pd-externals/mrpeach.pd_linux and failed tried /usr/lib/pd-extended/extra/mrpeach.pd_linux and failed tried /usr/local/lib/pd-externals/mrpeach/mrpeach.l_ia64 and failed tried /usr/lib/pd-extended/extra/mrpeach/mrpeach.l_ia64 and failed tried /usr/local/lib/pd-externals/mrpeach/mrpeach.pd_linux and failed tried /usr/lib/pd-extended/extra/mrpeach/mrpeach.pd_linux and failed error: [import]: can't load library in 'mrpeach' ... you might be able to track this down from the Find menu.

Also it seems that http://docs.monome.org/doku.php?id=dev:pd:simple_mlr uses an old version of OSC, functions names in code are like dumpOSC -> OSCdump ; how to run the script at the link below with 0.42.5, can anyone tell here? (will also bug monome's list). P.S. Why the article at gentoo wiki told me to remove oscx from build? Is there a reason for such thing to exist behind that article? cheers, there. don't forget to do awesome stuff next days, it's the last days of the year after all.
