Hi all, Just a note that at least in OSX 10.7.5 The following links are different http://puredata.info/downloads/template (doesn't work) https://puredata.info/docs/developer/MakefileTemplate (works) The first one is therefore a bit problematic... best, J

Limit bandwith for MIDI output / precise metro
by Jean-Marie Adrien 28 Aug '13

28 Aug '13

Hi list Im trying to cope with the MOTU Micro lite USB Midi driver under OsX Mountain Lyon. The stacking process of the driver is weird, means data are totally corrupted if they arrive too quickly to the interface, which does not happen with OsX Lyon, although MOTU announces full compatibility with OsX ML, anyway. I'm trying to make my own fifo from within PD, and, in this process, at some point I have to dump values out of the stack at "regular" time intervals. The straightforward implementation uses a metronome object, say with period 10 msec. The problem is that the metronome object is not precise enough, and it bangs erratically with time intervals within 0 to 20 msec, as measured with the (realtime) object, and this screws again the midi interface (everything else normal, dsp 10%). Is there an academic way to get a steady flux of bangs with short period ? Delay ? Hack some audio for control purposes ? (use a phasor~ ? :) Thanks Jm

midirealtimein error message, is it still needed?
by hard off 22 Aug '13

22 Aug '13

was just messing round with [midirealtimein] on linux. no problem it seems. my friend in berlin got it going fine on os x. so, is there still any need for the 'error: midirealtimein only works under MSW' message that is sent to the console upon load?

electro-mechanical piano (player piano) - Arduino, Solenoid Issue
by Epic Jefferson 16 Aug '13

16 Aug '13

Hey guys, I've had progress building an Arduino-powered solenoid system for a controlling a piano's hammer mechanism (removing the keys) via pd. So far I've found the solenoid I want to use. [image: Inline image 1] Does any one have experience daisy-chaining arduinos (or arduino mega's) to get more pwm pins, while using just one usb connection for controlling via pd? -- www.epicjefferson.com

Preset saving with SSSAD
by András Murányi 30 Jul '13

30 Jul '13

Dear list, i'm having a kind of naive question. I've been using the glorious SSSAD abstraction (with [presetstore]) to save&load presets in a huge patch, but i'm missing more and more the ability to save&load presets for individual parts of the patch only. E.g. i have two sequencers in the patch, for which i wish to save&load presets independently. I know it's easy to send presets to individual parts when you have hand-made those presets, but what about saving? Is it that the current architecture of SSSAD does not allow this? Then is there a way to modify/develop it to make this possible? Or if it allows, how to do it? Any ideas highly appreciated! Thanks, Andras

l2ork: SSSAD loads but doesn't save presets
by András Murányi 27 Jul '13

27 Jul '13

Dear List, I've been having a problem with SSSAD for a few weeks: it's able to load presets, but when it comes to saving, an empty state is written (i mean, it does write but it overwrites the previous content of the preset with nothingness). The example patches don't work either. There are no errors in the console and I have also overwritten the whole SSSAD folder with a newly downloaded one, still no joy. Tested in vanilla and it works.

[PD-announce] new version: Extended View Toolkit v0.4 Rotterdam
by Peter Venus 25 Jul '13

25 Jul '13

Hello All! We proudly announce the new version of ExtendedViewToolkit - the PureData/GEM abstraction library for panoramic image/video creation and projection mapping. It has been a long, but productive time since our last release. Tons of new features and fixes wait for being discovered by you. This new version was mainly done during a residency at moddr_/WORM in Rotterdam. Amongst other changes, you are looking on a completely re-designed storage-solution, that enables you to create scene-based video-mapping setups - with the possibility to add transitions between your scenes. Within each scene, you can automate basically every parameter in every module of the toolkit individually. We made a small technical teaser, to show what's possible with the scenes: http://vimeo.com/51567993 In addition to our multi-camera panoramic content solution, we integrated a module for creating 360-degree panoramic content made with spherical, one camera based, lens- or mirror-systems. Also, a new video player with instant and saveable controls for in/out-points, fade-times and loop, waits for being used within your performance. On the projection-side we added a module with 5x5 cornerpoints to allow more detailed settings when projecting on uneven surfaces with just one projection module. Furthermore we implemented a function to adjust the perspective distortion into the projection modules. We sticked to our fear of externals and made the whole toolkit out of plain PD and GEM without any other external libraries. For the usage of the remote-control features we recommend the usage of mrpeach´s OSC library. We tested the toolkit on different machines, and did not have any issues on Linux, OSX 10.6.8, 10.7.1 and also on Windows 7. If you discover any problems, please get in touch with us. Thanks to all the people who constantly support the development of the toolkit, especially Cyrille Henry, IOhannes, Seppo, Walter&Birgit of moddr and Patrick Pagano. Download it here: https://github.com/extendedview/extended_view_toolkit If you use it, we strongly encourage you to send us links, videos, images, etc. of your projects. We are amazingly interested to see what you create!

PDP test release
by Tom Schouten 22 Jul '13

22 Jul '13

Hello, There's a PDP release in the pipeline: 0.14.0: Port ia32 MMX assembly code to GCC extensions (MMX support on amd64) Add V4L2 support to pdp_v4l (merge with pdp_v4l2) Distill zl (Zwizwa Lib) from PDP and libprim/PF code. This is quite a big change internally and is not 100% stable yet. It should be functionally equivalent with previous version. I'm going to put out what I have now for people that like to try it out. If you run into a bug, post here or send it to pdp(a)zwizwa.be http://zwizwa.be/pd/pdp/test/pdp-darcs-20130514_145023.tar.gz Some known issues are GLX crashes when texture size changes and V4L1 support being broken. ( See pdp_v4l_hack for a new camera-specific setup hack that was necessary to get high FPS on a Microsoft cam. It might be useful for other cams too. ) Cheers Tom
