PiDiP does this good. BUT it is missing an OSX live input object (currently uses the V4L library) this is an urgent programming task for PiDiP but it needs a mac developer to do it Le jeudi, 29 jan 2004, à 01:10 Europe/Paris, roc a écrit : >> >> Re: Re : [PD] PDP or GEM linux DV CAM > >> In GEM under Linux, you will need to use the "pix_video" object and >> send a "driver 1" message.

GF/jMax in theatre
by Mathieu Bouchard 29 Jan '04

29 Jan '04

Btw: on January 14th-18th, in Calgary, was the first use of GridFlow in a theatre play, actually an interdisciplinary production incorporating elements of dance, poetry, gymnastics, short film, and actor-controlled display of pictures. Ken Campbell, in Ottawa, designed and constructed the wireless emitters/receivers/sensors, that were used by the three actors at chosen moments during the play. I designed the patches to decode sensor informations and process the visuals, and handled the equipment during the shows. Artengine (http://artengine.ca/) generously provided some equipment and funding. [My next plan is to present a tape of this show at the next meeting of Montréal PureData Users Group, possibly accompanied with talks by several involved people.] ________________________________________________________________ Mathieu Bouchard http://artengine.ca/matju

PD effiecientcy
by William Fields 28 Jan '04

28 Jan '04

Bradon, I've found that a lot of pd performance problems come from the GUI. While running your patch, open up the Windows Task Manager and keep an eye on the "pd.exe" and "wish83.exe" processes. I've found that the "wish83.exe" process corresponds to the GUI and the "pd.exe" process corresponds to the actual audio/midi/control processing. Keep an eye on the CPU% usage for these processes while using your patch and you should be able to see what the bottleneck is. I've found that changing states (e.g. via pool or state) will cause a big spike in the GUI process because many numberboxes/sliders/etc are being updated at once. Also, I've found that GOPs use up more GUI power. If the GUI is the problem, try putting as much of the patch as possible in a sub-patch and keep that sub-patch window closed... so you only have a minimal amount of GUI elements on the screen. This is where an external MIDI controller of some sort comes in handy, because you can tweak parameters without relying on the GUI. I hope this helps. -Bill http://www.williamfields.com/

PD problems with VST
by Bradon Webb 28 Jan '04

28 Jan '04

Hello, I am having trouble running pd as a VST. I downloaded the PDVST folder with ex pd-gain. I moved the pdVST folder into the FLStudio folder (this is the application I am trying to open pd within). I moved the example .dll pd-gain to the VST folder. When I go into FL I can get it to recognize a new plugin called pd-gain, but when I open it I get this error message; Plugin could not open, make sure that this plug in does not need to be regestered. I am guessing that FL cannot find where to open pd that will open the plug-in file pd-gain. I am pretty sure that I have all the files in the correct places, but maybe not... If someone has done this before and knows what I am doing wrong, please help. I am on a WinXP system. Thanks, Bradon __________________________________ Do you Yahoo!? Yahoo!

PD effiecientcy
by Bradon Webb 28 Jan '04

28 Jan '04

Hello, I am running PD on winXP laptop with 1.2 gig 512mB Ram, I don't seem to be having trouble running other audio or video applications, with processing so I feel like my computer is not necessarily the problem. I feel like I should be able to put more into my PD patches before they start cutting out from the audio calculation/processing. I guess the term is underuns? when the computer cannot process all the data within the specified unit of time to playback smoothly. I seem to be upward 50-70% cpu usage peaking.. my questions are thee; 1.how much (%)CPU usage can I expect to use while still maintaining smooth audio output? 2.If I redesign all my abstractions so there is no GOP or visual interface how much faster can I expect the patch to run (% cpu). 3.How do I make the patches more efficient? 4.How much does running other sound aps in the background while PD is running effect/contribute to the underruns... It doesn't seem like it is contributing much to the CPU problem, becasue I get underuns either way with it running, or with it off. Should I never do this? it seems like the only solution right now is to somehow cut all the tasks and render them to wav files and then use multitracking to put layers back together. which means live performance is pretty much out of the question at this point. I want to get 2x - 3x the performance I am getting right now. But that is just an arbitrary feeling of how complex I want the patches to be, If the machine can't handle it then there is nothing I can do about it, except become a better programmer... Thanks for any advice. Bradon p.s. I know it is kind of abstract to talk this way without a specific example, if anyone wants to see a patch of mine, I would be more than happy to post for a critique. __________________________________ Do you Yahoo!?
