[PD] why do [bp~] and [vcf~] sound different?
(posted this on the Pd forum, but it was suggested that I e-mail the list as well, so here I am out of lurk mode) I was working on some patches with bandpass filters that were initially [vcf~], but I ended up deciding not to vary the center frequency, so I replaced them with [bp~]. Now I find that [bp~] sounds different; e.g., a [phasor~ 100] going through a [bp~ 440 3] sounds different from one going out the left outlet of a [vcf~ 3] with [sig~ 440] going into its center inlet. I couldn't find anything in the help files indicating that they're different other than using control vs. signal for the center frequency, so what's the deal?

GEM has pix_share objects that allow for two instances of GEM to use the same images. Would this help you with the pix_sig2pix objects sharing pix data?

Re: [PD] Save gem output to a DV cam
The options for recording GEM output are: pix_snap + pix_record - post more details on your problems (OS, QT version, patch) pix_write - records still image sequences in tiff or jpg. QT Pro can make them into a .mov capture card for DVI or VGA - Blackmagic Intensity will record DVI at 640x480, 1280x720 or 1920x1080 resolutions. requires another computer or lots of cores on the same machine. capture card for S-video - if your graphics card has s-video output set the gemwin to 640x480 and record it with another computer.

The fourth edition of make art – What The Fork?! distributed and open practices in FLOSS art - will take place in Poitiers (FR), from the 7th to the 13th of December 2009. make art offers performances, presentations, workshops and an exhibition, focused on the encounter between digital art and free software. We're currently seeking new, innovative FLOSS works and projects: music and audiovisual performances, presentations, software demos, and installations. This year make art focuses on distributed and open practices in FLOSS art. 'What the fork?!' is about decentralisation. Forking is the new black. Forking, copying the source code of a project and continuing work on the copy instead of the original, used to have a bad reputation. It would split a project and its developer community in pieces, leading to different, often incompatible, projects. Wasted effort, rivalry and developer fights were all associated concepts. This is history. Forking a project with the intention to compete with it is another story, but the freedom to fork enables quick implementation of features and customization, bypassing acquiring committer status, bugfix or feature request protocol, working in a distributed way, together with others but not necessarily towards one goal, working from one source, cross-fertilising, inspiring, copying, patching, improving, experimenting, changing direction, and merging. This practice is boosted by decentralised software development tools, such as Darcs, Mercurial and Git. It's not about quick hacks, but about creating room to experiment, letting go of the one working copy and creating a multiplicity of ideas. Extended deadline : 22nd of July 2009.
