Re: [PD] system call

How about using the pyext external from Thomas Grill(if you're into python that is)? It's a long time since I've worked with it but the os.system module might be what you need. see: http://docs.python.org/tut/node12.html The glob module is good for cross-platform file listings as well, if you do a search for glob on the pd-list I seem to remember a good example of that one. Hope this helps!

'*' in filenames on windows
by Martin Dupras 14 Dec '06

14 Dec '06

I can't believe I have not noticed before now, but windows cannot have the character '*' in a filename.That does explain among other things why I could not unzip some example files (e.g. Patrick Sanan's MiniMoog.) I also noticed that the pix_kaleidoscope example patch uses a v* object, which doesn't exist on windows. Is there are workaround? - martin

Mutiple instances of a patch at startup.
by David F. Place 14 Dec '06

14 Dec '06

It's nice that I can list multiple filenames with a command line invocation: pd controlPanel.pd pythagGen.pd but, I would also like to list a filename several times to open several instances of the patch: pd controlPanel.pd pythagGen.pd pythagGen.pd Pd seems to filter out repeats, though. Isn't this something one would sometimes want to do? Pd must be making a special effort to filter out the repeats.

Re: [PD] tuning an AM radio ideas
by Roman Haefeli 13 Dec '06

hi nick again i didn't want to 'steal' your idea, but i found this subject so interesting, that i tried to realize that approach in a pd-patch. the patch needs [abs~] from zexy and [lp8_butt~] from iemlib. the patch has 3 'stations' (three sources modulated on differently tuned carriers) and one 'receiver'. because of the very high sampling rate in the subpatch (1.53MHz, when pd runs with 44100Hz), the patch eats quite a lot of the cpu. surprisingly it sounds a bit like am-radio, though the quality of the received signal is very bad. the choice of the carrier frequencies does have big effect on the typical am-radio artefacts. there are sure some things, that could be improved. maybe you have use for it. cheers roman On Wed, 2006-12-13 at 12:45 +0000, nward04(a)qub.ac.uk wrote: > yep, Thats kinda the approach I was thinkin of.

tuning an AM radio ideas
by nward04＠qub.ac.uk 13 Dec '06

Hi all, I was just wondering would anyone here have an idea on a starting point for a patch to simulate tuning in a station on an AM radio. I want to make a virtual radio with say 5 chanels that i can tune between replete with the hissing fizzing in between out of tune bits. Thanks Nick

hello ! i present myself : i'm a young art student in Angers (France ; so, forgive my bad english) and i learned to create patches with puredata in the workshop organized by goto10 at Poitiers (France) last january. Since this, i'm designing my own tools for the music i do, and now i'm trying to do the same for real-time images, using Gem. I'm using a debian with the "jack" environnement, in fact, something inspîred from the pure:dyne we used in this workshop (buit i'm thinking about installing it). But, I've got some problems. I asked my questions on the pure:dyne list and they drove me here ; they also said my problems might not be linked to pd but to my OS and my drivers. these questions are : -on my laptop, i've got an auxiliary video out (on the side there are a S-Video plug and a standard computer screen plug), and i would like to know if there's a way to send the Gemwin content on it (to display on a TV, for example). I think they're really separated displays since I manage to have an extended desktop on windows 2000 (glups !) : I can pass a window from the laptop screen to an external monitor (a TV or a computer screen). I tried to configure Xfree as I had readen on forums and howtos but I never got anything else that a grey screen. I heard about Xorg, is it better ? -with Gem, i'm using 6 layers (with alpha transparency) each one linked to a gemhead, and the whole rendered in a 320x240 resolution, it works very well. but when i switch on the fullscreen mode (with the argument « fullscreen1 »), the rendering is very slow (4 frames per second maximum, i think). is it normal, how can i remediate to this ? thanks a lot ! raphaël
