Re: [PD] GEM quirky-ness on OS X
by Pall Thayer 16 Jan '12

16 Jan '12

Hi Chris, Thanks for the suggestion but that didn't work. Some other weird issues are that my ".mov" file worked fine on linux but not at all on OS X. The only thing that would play it was VLC so I used that to transcode it and was able to get it working (albeit with the flashing) in other formats. But I noticed that when the frame motion was backwards, it would cause clicking in the audio. So I ended up transcoding it to jpeg and that got rid of the clicking but I still get the flashing. Any more suggestions? Pall On Sat, Jan 7, 2012 at 7:26 PM, chris clepper <cgclepper(a)gmail.com> wrote: > Are you doing any pix_ processing?

Can't get [arduino] to work (any more)
by Matteo Sisti Sette 16 Jan '12

16 Jan '12

Hi, I haven't been using [arduino] and Pd-extended with my arduino for some time un Ubuntu; it used to work just fine on Ubuntu 10.10. In the meantime I have upgraded ubuntu to 11.10; I haven't touched Pd-extended and I'm using the same version of [arduino] (and the same arduino hardware of course). Usually I would just open the arduino-test sketch and try "open 0", "open 1" etc until it would connect (I have bad memory). Now there's no way it will connect. Whatever number I try it says: "[comport] ** ERROR ** could not get termios-structure of device /dev/ttySXXX" The Arduino IDE does succeed in uploading a sketch (unless it says "done uploading" without knowing). What may I be missing? thanks m.

GEM on PIII memory problem?
by rolf meesters 16 Jan '12

16 Jan '12

hi i have an installation with a number of PIII machines, where some picture manipulation (2D) is done, working nicely on Win-XP and Flash 8 (in 256 Mb). now i'm trying to change from Flash to GEM. the patch i made works perfect on a P4. the PIII's don't have SSE2; therefore i rebuild Pd-ext 42.5 for Linux - (Ubuntu Lucid). however running the patch on the PIII still looks like impossible. Pd/GEM just calls it quits, no message. a basic picture consists of 16 pieces of 800 x 533 pixels, together forming one of 3200 x 2133. to create a full picture resized to 800 x 533 on a normal display, i have 16 identical abstractions, for each piece one, with a gemhead, a pix_texture, a resize, etc. with 8 abstractions/pieces Pd/GEM stays alive, 9 is one too many. memory problem? using the Ubuntu system monitor: bare system (with the monitor) ~290 Mb usage. (of 496MB) starting Pdx console ~300-310 Mb. loading/running the patch ~335-355 MB. ?? on the opening of the patch GEM anounces 8 bits will be used, where the onboard video-card has 24bits. any help is appreciated. rolf

PD in Vienna
by Krnk Ktz 15 Jan '12

15 Jan '12

Hi, I'm currently studying in Vienna (at least until June) and discovered PD recently, when I started getting interested with electronic music - which means I am not capable of anything with it actually, but I have some background with music and programming so I think it can be really interesting. I'd like to know if there are people in Vienna meeting regularly, showing each other their works - I've read about some meetings in the archives of the mailing list but that was a few years ago. Also, maybe there are some interesting concerts and/or lectures in some places I don't know: I have to admit that I'm getting tired of drum & bass and house. Anyway, if anyone reading this is in Vienna and has something to share, that would be great! Thanks, Marin

GuitarExtended
by Pierre Massat 13 Jan '12

13 Jan '12

Dear List, I wanted to let you know that i'm writing a blog called GuitarExtended. It's aimed at documenting my own experience in using Pd for live effects with my guitar, which involves the creation of a footcontroller based on Arduino. I've been working on this for more than two years now, so I thought, or should I say, my girlfriend made me write this blog to share it with everyone (i use open source software and hardware, it does make sense). My belief is that Pd is a wonderful oportunity for "regular" musicians who know how to play "regular" instruments to enhance them. The goal of my blog is to show that it is possible for a guitarist with some knowledge of computers to create a very flexible live setup that mimics and outdo any existing digital multi-effects. Although I'm fascinated by the work of some people in the list who try to create entirely new instruments using Pd for synthesis and/or effects, I believe that "regular" instruments have been "developped" for centuries and played and tested by musicians for just as long, and I think that DSP and computers should extend them rather than re-invent them. Anyways, here the url : http://guitarextended.wordpress.com/ You are most welcome to make comments and remarks and correct me if i wrote something wrong. Thank you all for your help over the past few year. You people have taught me everything i know about Pd and DSP in general! Cheers! Pierre.

[zyx-patchbay] graphical patchbay/router for control and signal connections.
by dmotd 13 Jan '12

13 Jan '12

hi folks, it's the start of a new year and i've had some free time to work on pd stuff after a long break. wanting to get myself back in the data structures head-space, i developed this little project, a graphical patchbay/router for control and signal connections. the premise is pretty simple, the interface provides a symbolic representation of an object pool which is created dynamically - when you make connections through the interface those same connections are created in the object pool. the main patch is 'zyx-patchbay.pd', which has a GOP container holding the data-structure, a subpatch holding the object pool and a subpatch for the logic. the secondary patches are 'zyx-pbi.pd', 'zyx-pbo.pd', 'zyx-pbi~.pd' and 'zyx-pbo~.pd', which act as wrappers to objects (typically s/r/s~/r~/throw~/catch~) and dynamically insert themselves into the patchbay object pool. there is an example patch for these objects at 'patchbay-test.pd'. i use the patchbay to provide a single patching interface for connections that may be scattered over many patches or in hard to reach places, for example to quickly reroute a signal generator to an effect and back to the dac. this has been particularly useful on the constricted screen space of my n900 phone, which also tends to be painful to draw connections manually. some features: * purepd (tested in 0.43 and 0.42-6) * colour coded object handles * multiple object handles can be selected to connect to another object * objects handles can be dragged around and rearranged for better readability (drag the tip of a connection wire or use edit mode to move object handles within data structure window). * state saving between saves - the object pool and connections are maintained and it's still possible to add more object handles. * full $0 namespace handling in case someone wants to hack it into a multiple instance GOP. some pitfalls: * currently no safeguards for bad connections (signal to wire etc). * arbitrary width of object handle - this is set to 50px, i've begun experimenting with allowing the width to be dragged but but it will require more tinkering to get right. * fixed GOP window size for patchbay interface - a trivial change but i've not needed to alter this yet and dynamically altering GOP can have some undesired consequences. i know that there are folks on this list that would consider this patch set blasphemous for using dynamic construction and abstracted interface to obscure workflow, but it fulfills my requirements and hopefully others will find it useful. if anything it's another example of data-structures that people can learn from or tear apart. i'm going to use the prefix 'zyx' for abstractions, so there aren't any namespace clashes, if you want to edit and release your own version please use a different prefix. i welcome any questions, comments or feature requests! cheers, dmotd

how to tidy up patches ?
by Фывапр Олджэвич 13 Jan '12

13 Jan '12

Hi ! is there any option in PD to make complex patches look less messy ? for example in MAX you can hide all the connections in performance mode.. in VVVV - you can spline the hords in MAX you also can make hords with different angles.. and so on.. is there any way in PD to tidy it all up ? i can't find it. maybe it is really something to do ? thnx , serg ! ----------------------------------------------------------------------

pd 0.43.1 installed, not installed
by Matteo Sisti Sette 12 Jan '12

12 Jan '12

Hi, On Ubuntu 11.10, I had pd 0.43 installed (it had been a long time since the last time I had used it and it used to be 0.42, so not sure when I switched to 0.43... either it has been automatically updated through Synaptic, or I had installed 0.43 to give it a try on linux though I knew it was unstable on Mac and Windows) Anyway, now I've downloaded the sources for 0.43.1 (there's no prebuilt ubuntu package, is there?). I've built it and installed it, apparently with success ("Pd install succeeded"). However, when I run it as "puredata", it still runs the old 0.43.0. Is the binary installed somewhere else than usual? Or maybe something went wrong silently during installation? Hmm actually there seem to be some error in the output from "make install", maybe the "install succeeded" message is just a fake? I entered the src directory and did: ./configure => no errors make => no errors make install I attach the output from "make install" below. This part scares me: ... make[1]: Nothing to be done for `current'. make[1]: Leaving directory `/media/DATA/downloads/programmi/pd-0.43-1/extra/stdout' install -d /usr/local/lib/pd/bin install ../bin/ /usr/local/lib/pd/bin/ install: omitting directory `../bin/' make: [install] Error 1 (ignored) install ../bin/pd-watchdog /usr/local/lib/pd/bin/pd-watchdog ... or is it fine?? thanks m. $ sudo make install [sudo] password for teo: cd ../obj;
