How to save an array embedded in an abstraction?
by David Schaffer 25 Nov '07

25 Nov '07

Hi everybody, I've built an abstraction that includes an array that can be modified by the user. I would like to know if there's any easy way to save/recall the content of the array or if I have to save the entire abs. under a differnent name evrery time the array changes? Thank you all!

Pd-0.40.3-extended and Pd-0.39.3-extended on 10.5 Leopard
by bsoisoi 25 Nov '07

25 Nov '07

Hey all, is anyone else having difficulties running either version of Pd- extended on OS X 10.5 "Leopard"? Whenever I hit the "Help" menu item, the whole program crashes. After this point, I am no longer able to save files, as the program will then crash upon save. I wouldn't be surprised if this is a leopard issue, has anyone had any luck getting around it? I've attached my crashlog. Thanks, ~Brandon

Hi Vircy sorry for the delay, i checked your edits and they look good. I did some of my own, based on the documentation, not the english pdpedia although i did read it. are we looking for something like this? http://wiki.puredata.info/es/line also, i am looking for the vanilla template as it is in the english version, but it doesn't seem to be up yet... is this true or am I missing something... best, J On 11/15/07, Hans-Christoph Steiner <hans(a)eds.org> wrote: > > You go it, Jaime. > > .hc > > On Nov 15, 2007, at 2:21 PM, Jaime Oliver wrote: > > > Hi Hans, > > > > It is Joliver, > > thanks, > > > > J > > > > On 11/15/07, Hans-Christoph Steiner <hans(a)eds.org> wrote: > >> > >> > >> Vircy, you are now, log out and back in to get admin rights. > >> Jaime, tell me > >> your pdpedia.org/es/ account and I can make you admin as well. > >> > >> .hc > >> > >> > >> On Nov 15, 2007, at 1:43 PM, Vircy Parker wrote: > >> Hallo Hans, > >> > >> only a administrator can to create the MediaWiki:Common.css > >> page...and > >> who is the administrator? > >> > >> :) Thanks > >> > >> > >> 2007/11/14, Hans-Christoph Steiner < hans(a)eds.org>: > >>> > >>> Ok, the import has begun, should be done in an hour or so: > >>> > >>> http://wiki.puredata.info/es/boids2d > >>> > >>> The next step is to make the Infobox template: > >>> > >>> http://wiki.puredata.info/en/Wiki_administrator_how-to > >>> > >>> * Create a page named MediaWiki:Common.css and copy the content > >>> from http://wiki.puredata.info/en/MediaWiki:Common.css > >> into it. > >>> * Create a page named Template:Infobox_Objectclass and copy the > >>> content from http://wiki.puredata.info/en/ > >>> Template:Infobox_Objectclass into it. > >>> * Translate the fields from Template:Infobox_Objectclass into your > >>> language.

pd filter with pole and zero
by cyrille henry 24 Nov '07

24 Nov '07

hello, i know there is a lot's of filter externals available for pd, but i'd like to use some using rpole~ / cpole~ etc. my main motiviations are : 1) i don't like using externals 2) this object allow an audio control of the cutoff frequency as there is not a lot's of exemples, i'd like to know if anyone used this objects to make good filter abstraction. or anyone have references in order to disign filter? (i'm looking for a low pass resonant filter by exemple) thanks Cyrille

problem loading pidip
by Rodrigo Treviño-Frenk 24 Nov '07

24 Nov '07

Hello everyone... I am using pd-extended 0.39.3, and whenever i try to load pidip i get the following error: /usr/local/lib/pd/extra/pidip/pidip.pd_linux: libMagick.so.6: cannot open shared object file: No such file or directory pidip: can't load library I first installed Image Magick from Synaptic manager, and after the first failure, compiled it manually; but still no success... i reinstalled pd-extended everytime after the i.m. installations. Pdp is loading fine, and since i DO have I.M., i've just no idea what is going on. I would appreciate any guidance on this, the best luck! furenku _________________________________________________________________ Express yourself instantly with MSN Messenger!

using chrt on pd to get rid of DIO errors
by Rich E 24 Nov '07

24 Nov '07

After setting up ubuntustudio (7.04) with a real-time kernel ( 2.6.20-16-realtime), I was experiencing DIO errors every few seconds. Exploring this taught me alot about how to set priorities on a real-time kernel, mainly with the command 'chrt'. However, I don't think it is meant to be used directly on an application, since there might be parts of the application that are not supposed to run in real-time at a high priority. Nonetheless, running: r@pal:/etc/sysconfig$ pidof pd 12079 r@pal:/etc/sysconfig$ chrt -p 60 12079 sets pd running as: r@pal:/etc/sysconfig$ chrt -p 12079 pid 12079's current scheduling policy: SCHED_RR pid 12079's current scheduling priority: 60 and the xruns go away. I don't know too much about the different threads pd is running on, but I was under the impression that pd is supposed to start in real-time with a high priority. Yet, due to the apperant changes from chrt, I would think that it was not running in real-time. I've tried this on versions 0.40-3 and 0.41-7, and real-time scheduling is not specifically turned off in the pd start-up settings. Any thoughts? regards, rich

performance on osX
by cyrille henry 24 Nov '07

24 Nov '07

hello, i just made a performance test on osX, using pmpd exemple 22 (i had similar problem with other patch, this is just an exemple) with pd extended, or pd/Gem and pmpd compiled from cvs, this patch use about 40% CPU on a macbook pro 2.33Ghz. on my computer (dual core 2Ghz), it use about 22% (in both case, % are mesure for only 1 CPU : both computer are dual core) i did not do any thing special in my computer to optimise compilation, nor in the macbook. could anyone with a macbook pro could test this patch and tell me the CPU used? does anyone know why the macbook is so slow? thanks Cyrille

Pd performance os OS X

This is statement is factually incorrect as noted elsewhere. Some points to consider: 1. Aqua is the name of the visual theme of OS X 10.0 circa 2001. 2. Quartz (Quartz Extreme if you must) is the window rendering engine on OS X and it runs almost entirely on the GPU. The WindowServer process does manage some other chores and runs on the CPU uses only about 1% CPU. 3. Core Audio is extremely efficient and a well-written Core Audio app will take very little CPU especially when idle. 4. Well-written CLI apps run as fast or faster on OS X as on other Un*ces. 5. Extremely sophisticated audio and video applications do run quite well with reasonably low CPU usage on OS X. Maybe my previous top data was too subtle. A quick check reveals that for some reason, just turning audio rendering on soaks up about 20% of the CPU and seems to involve a fair bit of thrashing about in the kernel and memory. I don't know enough about the internals of Pd to add any more insightful comments, but here are some raw figures comparing Pd and iTunes CPU and system usage: Pd idle audio off: 1.6% CPU, 1000 SysCalls/sec (Mach + BSD) idle audio on: 21% CPU, 4400 SysCalls/sec (Mach + BSD) #22 patch open: 29% CPU, 4700 SysCalls/sec (Mach + BSD) #22 patch w GemWin: 34% CPU, 5300 SysCalls/sec (Mach + BSD) #22 patch running: 46% CPU, 5300 SysCalls/sec (Mach + BSD) iTunes idle not playing: 0.0% CPU, 5-20 SysCalls/sec (Mach + BSD) playing: 9.3% CPU, 900 SysCalls/sec (Mach + BSD) This could have to do with PortAudio as the glue to CoreAudio, I don't know. Thomas Grill was quite right. What is needed is for those with the time and motivation to use the performance profiling tools (such as Shark, Sampler, BigTop etc.) which come with Apple's free developer tools and dig into Pd to discover what is chewing up CPU cycles. Here are some guides: Performance Guides: http://developer.apple.com/documentation/Performance/index.html Performance Tools: http://developer.apple.com/documentation/DeveloperTools/Performance-date.ht… cheers, Andrew

PDpedia : images
by Olivier Heinry 23 Nov '07

23 Nov '07

Hi, when we add images to the mediapool, should we make screenshots in the new fashion such as http://wiki.puredata.info/images/3/3c/Gemframebuffer.png or stick to the old-fashioned look we all know? bye, O.
