Re: [PD] [GEM] pix_video, Win 2000, Matrox
by Ian Smith-Heisters 27 Mar '05

Found out some more things, remembered some details. I'm running GEM 0.90.1 In Premiere, when I try to capture using anything but the Matrox drivers, eg. Microsoft's driver, it doesn't work. "cannot connect to device" When I try to access device 0 with [open 0( pd.exe crashes, saying it generates a log file, but I don't know where it puts the log. -ian > Hello all, > > I was wondering if any one has experience or suggestions with/for this > problem.

[GEM] pix_video, Win 2000, Matrox
by Ian Smith-Heisters 26 Mar '05

26 Mar '05

Hello all, I was wondering if any one has experience or suggestions with/for this problem. I've got a patch that uses [pix_video] to pull in a DV stream. It works fine on both of my Windows XP Pro machines, one of which has built in firewire, and the other uses an Audigy soundcard for firewire. When I try to use the same patch on a Windows 2000 machine, with the same Sony DV camera, I get some odd errors. First, the Win 2000 machine has 2 firewire ports, one on an Audigy soundcard, and another on a Matrox RT X100 Pro. This computer also has a Radeon 9800 (Pro?) video card that I'm using for output. Sending [enumerate( to [pix_video] outputs this: Dev 0: Microsoft DV Camera and VCR Dev 1: Matrox Video Capture Device Both [open 0( and [open 1( do not print errors, but neither displays the DV stream. The first displays nothing, while the second displays a black screen with red, green, and blue dots interspersed randomly around it. I have captured from this camera, on this computer, in Premiere, over the Matrox firewire. Neither the matrox or audigy firewire ports register any new devices when the camera is plugged in, like WinXp does, but I'm not sure if it should do that. Any thoughts? Thanks, Ian -- http://www.0x09.com

external: notehigh, notelow
by federico 26 Mar '05

26 Mar '05

after playing a lot with h_stack, h_vector & co, i realized that this work is too much complex to do in pd, and very easy to do in C. so i coded these two external: notehigh and notelow. you can find them at http://xaero.ath.cx/cms/software P.S.: i lost some data on my hdd. some time ago i posted another external named tension. since i lost code and ML archives, can someone search it and send to my address, so i put it on the website? thanks

Hi all- Installing Gridflow on Linux and got the following make error: cturner@vatic:/usr/local/src/gridflow$ make ruby -w base/source_filter.rb base/grid.h base/grid.h.fcs make: ruby: Command not found make: *** [base/grid.h.fcs] Error 127 Here's what I got in my ../base directory: cturner@vatic:/usr/local/src/gridflow$ ls base MainLoop.rb flow_objects.rb grid.c main.rb test.rb bitpacking.c flow_objects_for_image.c grid.h number.c usb.c flow_objects.c flow_objects_for_matrix.c main.c source_filter.rb Am I missing a file? My Ruby executable is named ruby1.8, which the makefile seems to get: ruby = /usr/bin/ruby1.8 Any ideas? Best, Charles <vze26m98(a)optonline.net>

multiple colour tracking with GEM?
by David McCarthy 26 Mar '05

26 Mar '05

Greetings List, Is it possible to use several ( pix_movement -> pix_blob )'s to find several items of the same colour on the screen? IE if the items were all 'red' and set in a grid form, you could get your white cube (as in the example patch!) to cover each of these 'red' areas?? Further (!) how would one analyse the percentage of 'red' in these selected areas!? Thanks a million :?) David.

PD Repertoy Project info
by ggkarman＠musicologia.com 26 Mar '05

26 Mar '05

Hi, I am very interested in the PD Repertory Project, as a musicological & performance tool. I would like to find out about any other efforts done in the same direction as Millers PDRP patches, for eg. i've seen several edus are teaching live electronic classics, but haven't found any more patches out there. What is the expected future of PDRP in the short? Is the music to be included restricted to originally pd/fts/max.. pieces? I imagine there are also copyright issues to be considered when making, using, or uploading a patch that performs/aids a piece (apart from having to rent the scores/audios), specially in such recent repertory. What is your experience on this? (for eg. if i want to perform a piece or make, and upload to pd.info a patch that does) I have ocassionally used PD for trying to mimic pieces/processes myself. If there are any efforts in this direction, i would be delighted to give a hand. greg.

stack component
by federico 25 Mar '05

25 Mar '05

hi all, is there a stack component for pure-data? my search thru the pd-list and pd-database returned zero results. i'm developing a monophonic synth with portamento, and i would like to emulate the classic portamento behavior that most (monophonic) synthesizers have. i.e.: i hit C3: osc plays C3 i hit F3 (without releasing C3): osc slides to F3 i release F3: osc slides to C3 in order to achieve this, i need the classic stack container, with methods push (for note press) and pop (for note release). which component is more appropriate for this (if it exists)? otherwise, how this can be implemented? thanks! -- Federico
