2 Gem questions
by Oded Ben-Tal 26 Apr '05

26 Apr '05

1) is there a way to generate a file (in whatever video format) from gem graphics? 2) I get clicks when playing sound while also doing graphics. Playback (using sfplay~) is fine if I'm not rendering graphics. I'm running RH9 (planetCCRMA) with an m-audio soundcard. I'm not using Jack just alsa. The first question is in part a way to bypass problem 2 i.e. can I generate the graphics into a file and than mix it with the sound separately. Thanks Oded

Unfortunately it doesn't look like you can change the shift amount other than with the creation argument, so alternatively you can tabsend~ input to a temporary table, then tabreceive~ a table of indices which you use to tabread4~ the temporary table. The table of indices can be 0,1,2..63 (assuming block size=64) for no shift, 1,2..64 for left shift 1, etc. even fractional shift if you want.

PDDP release (Pure Data Documentation Project)
by Hans-Christoph Steiner 26 Apr '05

26 Apr '05

Though Dave Sabine seems to have disappeared from Pd land, I have continued to work on the PDDP patches. I have been including them in my Pd.app builds for a while now, now I am making a release for general consumption. The key idea behind the PDDP patches is that common ideas are linked together via "all_about_" patches. Its definitely a work-in-progress, so some parts are incomplete. http://at.or.at/hans/pd/objects.html Currently its using Guenter's [pwd] object, that's the only real dependencies. Its necessary for the link functionality. x86/Linux and Darwin versions of [pwd] are included. .hc ________________________________________________________________________ ____ http://at.or.at/hans/

Installation mit GEM

Are the necessary externals like pix_movement2 and the stock GEM modules available for windoze too? Thanks, Florian

Hi list, James, Patrick! Any chance you people could share that OSX binary of Gridflow, providing people have the necessary libs installed (just like OS X PDP is distributed nowadays)?

To me, there is nothing really telling who counts as a PureData "developer" or not, not even membership on http://sf.net/projects/pure-data. Furthermore, those meetings happen on the #dataflow channel, which is already open to everybody. You just have to be able to log onto the FreeNode IRC (irc.freenode.net:6667) > I am not currently contributing any code to the project (this may > change), but I suspect I may have worthwhile opinions on certain matters > that come up. Thanks. I am interested in the opinions of whoever has got pertinent and insightful opinions, no matter who they otherwise are. Note that I would recommend that everybody who plans to attend those meetings subscribe to the pd-dev mailing-list. ,-o---------o---------o---------o-. ,----. | | The Diagram is the Program (TM) | | ,-o----------------------------o-. `-o-----------------------------o-' | | Mathieu Bouchard (Montréal QC) | | |---' | http://artengine.ca/matju | | | `-o------------------------------'
