RE: Video Feedback (was [PD] feedback in gem, any tips)

I've only seen video feedback done in analog. Take a camera, hook it to a TV, so the TV shows what you're filming, and then film the TV screen. I would guess that the delays on processing digital data on a computer would make it impossible to do on a computer, but I may be very, very wrong. Try hooking any object's output to its input and you've essentially got a feedback loop. I don't think you can do this in GEM though. -Ian > -------- Original Message -------- > Subject: Re: [PD] feedback in gem, any tips > From: "=?iso-8859-1?q?type=5Fnon?=" <type_non(a)yahoo.com> > Date: Tue, April 06, 2004 3:56 am > To: PD-list(a)iem.at > > I didn't saw that graphic... but i'm very interested in this kind of > "visual feedback" patches too.

RE: [PD] pd 0.37.1 Windows installer release candidate

there is no .pdrc for windows at this time.

Re: [PD-announce] GEM 0.888 release-candidate 2 : codename 04/04/04

hi johannes sorry for disturbing but i have a little question: i am suffering of this problem since one year now... the trouble is with pix_rtx. (windows...oh...). well the combination of pix_rtx and pix_film or pix_ multiimage or pix_movie and all other image displaying objects leads to a crash... someone fixed that bug for me (i had to do an installation in berlin..) and compiled me a dll were it was working. anyway. this was one year ago and (as i tend to loose things) i lost that dll. i think that this bug should be fixed in the "normal" gem.dll versions. (as the guy told me that is was not hard to "repair". the big problem is: that i should have a working combination of pix_rtx and pix_film at friday. so... if its somehow possible... maybe you could have a short look at pix_rtx and tell me if there would be the possiblity to fix it until friday... sorry sorry sorry... i am always late with my problems... should have told earlier i think... regards wolfgang At 17:25 05.04.2004, you wrote: >hi all > >surprisingly for all comes that i have put a release-candidate for Gem on >the iem-pages; > >you can download from >http://gem.iem.at/download.html >or >ftp://iem.at/pd/Externals/GEM/ > >for users: >as for now, only windows-compiles are online. >there is a a gem-bin-dec-0.888rc2.zip file that holds the documentation >and the Gem.dll; >just unpack it into your pd directory. >(the zip files are relative to the pd-directory; so the extra\Gem.dll >should be in path\to\my\pd\extra after unzipping and you don't have to >execute a .bat file to run it) > >for devs: >it does not yet include the very recent changes of chris, as i have >compiled it yesterday before they were checked in... > > >mfg.asd.r >IOhannes > >PS: my announcement-mail yesterday somehow didn't make it (probably i >forgot to hit send) > > >_______________________________________________ >PD-announce mailing list >PD-announce(a)iem.at >http://iem.at/cgi-bin/mailman/listinfo/pd-announce

[GEM] help writing GEM externals
by Gabriel Westmaas 06 Apr '04

06 Apr '04

Hello, I have started writing GEM externals, but I suspect there is an easier way to do it than the way I have been doing it. Right now, I write a new external (or at least modify an existing external) within the GEM src folder structure, and then re-link the entire GEM library. Is it possible to just build an external and load that library when you start pd? If yes, what should the compile command look like? Thanks, Gabe

Re: [PD] controlling amplitudes with graphs

To make sound clear use [line~] object - this way you'll avoid clicks.

munger compilation on linux
by luigi rensinghoff 06 Apr '04

Hi !! Hi, i downloaded percolate from parasitaere kapazitaeten to check if i can use it as a pitch schifter. I am running RedHat Linux after i did make pd_linux i have all the files but munger does not work. It does actually block the audio. vibraphone and scrubber worked. Any Idea what that could be __________________________________ Do you Yahoo!? Yahoo! Small Business $15K Web Design Giveaway http://promotions.yahoo.com/design_giveaway/
