PD as MIDI controller
by AshK 21 Dec '05

21 Dec '05

Hello, I want to use PD as a MIDI controller, I have some patches that render MIDI notes and I want to send them into softs like Reason. I just don't know how to do it, can't find it in the doc or google so I ask here. (under MacOS X 10.4.3 with Pd-0.38.4-extended-RC1, I'm going for RC6) Thanks, AshK

pdp_qt BUS Error
by pat pagano 21 Dec '05

21 Dec '05

sorry if this is a repost finally saying goodbye to my college email server i am having problems with pdp_qt one machine plays the file loads it with SVQ1 etc.. then another crashes with a BUS error, i am not sure how to pinpoint what is failing. I am loading the same sorenson 320240 video files fine on one machine anyone else have this problem? Pat

GEM :: movie duration & speed
by emmanuel lefrant 21 Dec '05

21 Dec '05

Hi, I use [pix_blob] object to get the RGB info of an avi file, which then controls the volume of three different audio files. With [writesf~] I then generate a .wav file (44100Hz, no pitch-shift) that I can use (for a different purpose). The issue is that the duration of the output (.wav) is different than the duration of the movie... Some more info: - My computer (WinXP) is a P4 at 1.6GHz with 512Mb of RAM and an All-in-Wonder Radeon 7500 video card. - The avi file is 4'55'' long, 30fps, it results in a wav of 7'22''. I tried with another avi file generated with Premiere at 12fps, it results in a wav of 3'00''. I also tried with a quicktime movie with the same result. Wished result: 4'55'' = (4*60+55)'' = 295'' Obtained results: 1/ wav = 7'22'' = (7*60+22)'' = 442'' at 30 fps = 8850 frames (thanks to the 2nd outlet of [pix_movie]) 2/ wav = 3'05'' = (3*60)'' = 180'' at 12 fps = 3540 frames It seems pd reads the video at app. 20fps. Can we enter a fps as an argument somewhere so that the video is read in pd at the right speed? Do you think it could be because of the CPU usage? Any idea? Thanks in advance, emmanuel

PDDP Homework & Meeting Notes Dec 19th 2005
by B. Bogart 20 Dec '05

20 Dec '05

PDDP Meeting Dec 19th 2005 _Issues:_ * Encourage code sharing * patching style * implimentation vs creation (abstraction design) _Content Ideas:_ An assignment for students in the higher levels is to create a high-level abstraction. This abstraction is means to solve the problem of either A: A fellow students creative problem or B: provide more high-level abstractions for lower-level students. This would benifit the students by: * Students learn to describe the problem they are solving. * Students learn to communicate that problem to one and other. * Students are encouraged to make use of the efforts of others. * Enourages students to look at problems from other points of view. _What is the Purpose of these workshops?_ * Learn Pure-Data? * Create media outside the context of commercial markets? * To get back some freedom and genuine experience? * Is the purpose of the workshops not the same as the purpose of PD itself? Workshop Draft (partical) _Level 1 (Intro)_ * Image * Loading a still image (high-level, window&file hidden) * Using a numberbox to control the size of the image * Loading a video clip (same abstraction as above) * Using number box to scrub video frames * Using metro to control clip playback * Sound * Load a sound file (high-level, table&soundfiler hidden) * Play sound file back with phasor~ * Srub sound file with numberbox * Create sound (high-level FM abstraction?) * Change sound quality with numberbox * Network * Read MIDI values (simple MIDI abstraction) * Add midi control to control frame of video & tone of FM synth * Physical Media * HW interface (serial&processing hidden) * push-button advances frame and triggers sound-file. _Level 2 (less Intro)_ * Image * High level PDP patch that has three abstractions: * load an image file * blur effect * output to window *HOMEWORK Assignment For Developers* Today we talked about extending the concept of the project based workshop into the workshop materials themselves. That is each level of a workshop (above we have level 1 layed out and level 2 is particially done) is brought home by using a different project example. That is each level would have a creative project already developed that would serve to inspire the students individual projects, as well as give meaning and context to the technical details (implimentation) So for your assignment you need to create a project idea that: * Fits in with a particular level of the workshop (level 1 is introduction and level n is advanced. Just choose a number from 1-10 to describe the level of the project. * The project should be pretty simple in terms of concept and as technical as your chosen level allows. * Require as few externals as possible * The project has to be feasible * The project has to be inspiring! * Ideally it will encompass all four threads, image/sound/network/physical For the next meeting on January 9th 2006 all PDDP contributers should have developed a project concept and implimentation that could work as teaching material. An example project from my Metaphorical Networks lecture is: Concept: * As the sun rises an eye opens Implimentation: * An LDR connects to a multiIO which reads the voltage * We read this value and scale it to 0-100 * The 0-100 value controls which frame a video of an eye opening is playing. Yes this example only has visual and physical media. This page is available on the PDDP wiki @: https://www.puredata.info/dev/pddp/BBogartsMeetingNotes20051219

hi, sorry for my late reply yes, please send me a copy of that file. I have modified it for OSX with pdp2gem and it works fabulously on one machine. On other machines i use i get an error when loading the movie files. When i load movie files on the working machine it says loaded file svqc etc.. and load the file on the other machine it says not a quicktime file or no usuable video stream found than crashes with a [BUS ERROR]. Testing pdp_qt, seems to give the same error. I guess i should start with versions of pdp? Patrick Pagano Digital Media Specialist University of Florida Digital Worlds Institute 352-294-2082

Open Sound Control in Mac OS X
by Item State 20 Dec '05

20 Dec '05

hi all, how can I use OSC in PD on Mac OS X? I've seen this thread : http://lists.puredata.info/pipermail/pd-list/2004-07/020911.html ...but all I get when creating the file ~/.pdrc is an addtional message at startup "OSC: can't load library". i have installed PD 0.38 from http://at.or.at/hans/pd/installers.html which alleges to contain an OSC library ... ? the site that is most referred to when googleing for PD/OSC (http://barely.a.live.fm/pd/OSC) doesn't seem to exist any more. also there seem to be different libraries (i.e. i saw someone talking about a "routeOSC" object, another one using "OSCroute" ... none of them seem to be installed with my version). thanks for help. ciao, -sciss- Send instant messages to your online friends http://au.messenger.yahoo.com

There are also the arduino and wiring boards that talk nicely with many progs.

Re: [PD] Pd-0.38.4-extended-RC6 release
by Hans-Christoph Steiner 20 Dec '05

20 Dec '05

Questions like these work best on the Pd-list, so I am CC'ing it. Pd-extended is Miller's Pd plus tons of objects, documentation, examples, etc. from ranging from video support, physical modelling, serial port/HID device support, and lots and lots of other useful things. Pd-extended also has a few patches to the core of Pd, but basically, its the same at the core. .hc On Dec 20, 2005, at 11:41 AM, Nuno Godinho wrote: > Hi Hans, > > I am sorry to bother you.
