Survey back online
by Andrea Mayr 17 Oct '02

17 Oct '02

Dear PD'ler I'm sorry to bother you again, but for the last little while our server was offline (our ISP in Germany changed IP's without telling us), so some of you might have tried to access the survey and found the server unavailable. I apologize for that. Now it's online again and may I ask you for a last time -- I promise :) -- to take the time to fill out the survey, I extended the deadline for another three days. I'm sorry for this hick-up and I hope my survey and the surrounding email have not been too intrusive. grtz. Andrea

hi, how could I compile pd, which is optimized for my CPU (on Linux)? How could I do the same for externals?

GEM zoom emulation !
by André Schmidt 17 Oct '02

17 Oct '02

hi all, i notized that [pix_zoom] doesnt work (atleast in win2k), so i started to think on an emulation for zoom using scale&translate... and oh yeah, i got it -> [_gem-mousezoom] (i started to use character "_" before patches that i use as "objects") what it does: - leftButton (in gemwin) pressed you can select an area where to zoom - rightButton (in gemwin) zooms back to original size how i did it: - leftButton pressed -> calculate X&Y pos in prosents (for translate) - leftButton released -> calculate X&Y size to picture size in prosents (for scale) - rightButton pressed -> reset translate&zoom quite simple, me think. and it seems to work quite accurate, but i only tested with one size of picture&video yet... so please report me of bugs/tips i'm not aware of, thnx... here's the code & a test : http://www.vju-tv.net/zoom-emu.zip (open gem-zoom-emu.pd and read the instructions) [i used pd0.35-1, gem0.87 & zexy1.1 on win2k] cheers -andre ps. can i delete files with pd (on windows!) ?

Re: [PD] installation trouble... perhaps a hardware inconvenient?

I had a similar problem with a PD class I was teaching (dual 500MHz machines with win2k) they had onboard audio cards as well, not sure what manufacterer. I tried a few machines and had this very problem with the audio, in the end we had to drop the audio stuff and just do Gem. Perhaps onboard cards just have issues? Good luck.

thank you very much, Sukandar >chip. For me calling pd with -audiobuf 500 helps. Dunno if you tried that oh no! I didn't. i'll do tomorrow >A different sound card should help too. indeed :) I guess this is the main problem cheers jose manuel -- Jose Manuel Berenguer jmbeal(a)telefonica.net +34932857046 696538403 jmberenguer(a)cccb.org +34933064128 http://212.163.142.140/jmb/index.html http://sonoscop.cccb.org http://ocaos.cccb.org/caos Sonoscop/Orquesta del Caos.

ultra newbie, looking for some assistance
by Mike D'Ambrogia 17 Oct '02

17 Oct '02

What a great program -- but I can't figure out if its a thin app that has thick feature set, or a thick app that looks & runs thin... Stumbled across the program today after weeks of searching for something like it, without knowing that it was pd that out there all the time. Spent the day going thru the help files, learning about how it works, and finding links to various sites -- I'm still a bit overwhelmed here at the end of the day at what it can do. Anyhow, I'm going to use pd for a fairly simple audio recording solution that I'm trying to put together but I'm hoping that someone will be open to lending a consulting hand. I've got a MOTU 24i ADC (24 ports) that I want to capture some audio out of and save to hard disk, need to run 5+ ports simultaneously, and write .wav files out. I see that pd will allow me to do this, but I'd like to get a jump start on creating the program correctly -- i.e. avoiding some bad design mistakes, and then start extending the functionality myself as I learn more about pd. If there is someone on the list who would be interested in helping me out in a paid consulting capacity please contact me off list (miked at craniumproject.org). This would help me get the foundation of what I'm trying to build together quickly, with a better design than I have the capability to develop, create a good code base, and jump start my project. I have a thought out project spec with flowcharts and a narrative that I can send over to anyone interested - just need to translate it over to pd style info... While I did search the archive to see if this somehow violates the spirit of the list I didn't find anything - but if it does I'll apologize in advance for the intrusion. Looking forward to playing the role of "the sponge" and soaking up as much info as I can about pd going forward. Mike

Re: [PD-dev] PD canvas interaction - flext GUI

hi all, Am Mittwoch, 16. Oktober 2002 19:12 schrieb guenter geiger: [...] > In my opinion more of the GUI stuff should be done on the GUI side, > and not from within pd,... but I might be completely off topic with this ? > > Guenter > [...] as some people might already know, im working on a new gui for apps like pd, jmax, etc... i choosed to use the qt toolkit for serveral reasons : it is multi platform (unix, os-x, windows), fast, good looking and it has a lot of functionality. another big point in choosing qt is that it uses a similar paradigm as tools like pd/jmax/.... you create widgets which are connected together via slots/signals. so you can make (for example) a number box and a slider, and then you say something like "connect(slider, SIGNAL( changed() ), numbox, SLOT( setnum() ) )" it is fairly easy to build own widgets...... the one and only "problem" is, there is only the unix/x11 version available for free (in sense of gpl software). but since i expect to hav a license for the os-x and win platform at christmas, it should be no problem to create legal binarys for those platforms. another big advantage is that stuff like network i/o and file i/o is already encapsulated into that lib. so the porting would be really only a recompile on the target platform. currently i am more or less in the planning phase, and currently i dont have that much time (which will change in some weeks). so i can not show you any usable stuff currently. but for those who might be interrested in how it can look, see http://mamalala.de/karma-preview.tgz it is somewhat like a "playable screenshot", and it is for linux. its the whole kdevelop project, so it is rather huge. you need qt3 to get it compiled, kdevelop is not really neccesary. some words of how it is designed : if you move, resize, etc. an object, all that is handled by the object itself. the result is then sent to the "server" which then has to dispatch the message to the real server. an object can either have a fixed drawing routine (as it is currently) , or it can interpret drawing commands (like those from pd, not done yet) the in/outlets are also widgets, and not drawn by the object itself. the current code does not show any in/outlets, but the code is there (its just that the object doesnt create a visible in/outlet yet) would be nice to hear from you what you all think about that idea ... keep in mind, its nothing usefull yet, just a playable screenshot ... ;) if someone is interrested in helping me with that, you are welcome ... greets, chris
