Chicago Patching Circle (Sunday, March 29th 5pm)
by Mike McGonagle 20 Mar '09

20 Mar '09

Hello all, I would like to invite any and everyone to a patching circle at the Red Line Tap on Sunday, March 29th. ( http://www.google.com/search?hl=en&q=redline+tap+chicago&btnG=Google+Search… ) I am planning to give a short demo of the SQLite externals I have been working on. The Red Line has a nice selection of beers for those into beer, so come on out and share!!! Mike

Well, we didn't get accepted but now at least we do have a nice collection of projects for people to take on. http://socghop.appspot.com/program/accepted_orgs/google/gsoc2009 .hc BZFlag? I guess PD is not a Google MicroSoft fighter ... although it's kind of annoying to see rather large, funded projects getting preference over deserving projects such as PD. Mabey they'll site a lack of developer cohesion as PD is something different for everyone involved. Bastards. --- Dan Wilcox danomatika.com robotcowboy.com

hello, i just stumbled on "toonloop": http://alexandre.quessy.net/?q=toonloop just got me interested/curious if someone has written a similar patch in pd (toonloop = processing.org).... thanks! mark

Frank and all, Attached is an inversion.pd which is a bit simpler -- usually when inverting in pitch (rather than pitch-class) it's easier/simpler/better to invert with respect to an axis of symmetry rather than with respect to the first pitch in the series (of course you can assign the first pitch as the axis). Meanwhile, if you're doing this with pitch-class instead of pitch (in other words transposing and inverting in a mod 12 universe, which is what you would probably be doing with 12-tone rows before assigning specific registers), instead of inverting with respect to an axis of symmetry, you invert with respect to the sum of the two pitch-classes in the original and inverted row -- sometimes called the "index" of inversion. The group theory is even cleaner if you think of transposition as an addition operator and inversion as a multiplication operator (in this case multiplication by 11, mod 12). If you're doing mod 12 operations, there is one more pitch operator -- multiplication by 5 or 7 -- which maps the chromatic scale to the circle of fifths and vice-versa. Then you can think of retrogression as "order inversion," and rotation, the other standard order-position operator, as "order transposition." If you think it would be useful I can put together the standard 12-tone operators in mod 12 (or for that matter, an assignable modulus), but of course specific register information disappears. A more interesting but more difficult project would be to write a list abstraction to output the set-class of a given set of pitches, with an assignable modulus. Matt

What is the largest integer not exceeding 0 (zero)? I've asked before, but I'll still like to know. Best, Steffen

hi list, I am pleased to announce that the big pd tutorial I wrote in the last years with the help of a grant by the Music University of Freiburg / Germany, is now online, in english and in german. It is also available as a book (paperback) at Wolke Publishing House, where the "bang" book was released. At the moment, Amazon says that it's not available, which is strange because it's definitely released, but at least it can be purchased at the Publishing House itself. http://www.pd-tutorial.com http://www.wolke-verlag.de/musik_u_t/loadbang.html http://www.buecher-zur-musik.de/assets/s2dmain.html?http://www.buecher-zur-… http://www.amazon.de/Loadbang-Programming-Electronic-Music-Pure/dp/39360005… Cheers Johannes

Pd book sprint in NYC/Berlin
by Hans-Christoph Steiner 19 Mar '09

19 Mar '09

Hey all, Adam Hyde, Derek Holzer, me, and others are working to organize a Pd book sprint to continue work on the Pure Data book that was started before. It is looking like it will be in early April (soon!) and both in NYC and Berlin, connected via video streams. We are still working out the details, but I just wanted to get the word out now so that people can plan on it and come and participate in Berlin or NYC. One thing that could be very useful is advice on how to best stream this kind of thing. For example, should we use GISS? Ekiga? Skype? .hc ---------------------------------------------------------------------------- 'You people have such restrictive dress for women,’ she said, hobbling away in three inch heels and panty hose to finish out another pink- collar temp pool day. - “Hijab Scene #2", by Mohja Kahf

C::NTR::L - AV+physical computing processing
by Marco Donnarumma 19 Mar '09

19 Mar '09

Hi all, i'm really glad to share with the list my latest project, cause without the help of everybody here i wouldn't be able to speak about it now.. ;) C::NTR::L is a "software", naturally Pd-based, for audiovisual live performances exploiting physical computing. It transforms a standard musical instrument in an augmented tool to control real-time audio-video processing, without the need of any external device (damned expensive) or MIDI. You play your score and to each note is connected an audio, video or audiovisual fx, and you can connect whatever you want with whatever you desire. It's Pd! C::NTR::L is Cross-Platform for Mac, Linux and Windows (so far i've been able to keep the same patch working on all platform, too lucky...) By now it has been succesfully tested with electric bass guitar, guitar, piano (only two octaves working right now), accordion and trumpet. I conceived this project almost three years ago (when i was just starting to get aware of the existence of Pd). I was playing the bass guitar trying to control videos with resolume :( and sound with AudioMulch. wow.. i cannot figure out how! anyway, since my competences and passion for Pd grew up, i decided to make the whole project become a software for public use and to do it exclusively focusing on Pd. Today this is the result (I C::ntr::l Nature, my audiovisual performance for electric bass guitar and butterfly): http://vimeo.com/2225345 I sent out a call for beta-testers on the most used audiovisual-related forums (Pd forum too), i fixed most of the bugs and someone is planning to do things with my lil creature. Now I'm planning the public release of version 1.2 Beta in the end of this month (if i won't be eated by my everyday job). I'm writing to the list not only to let you know the news, but specially because i would like to know if there is anybody out there who has time and will to help me in the cleaning and further development of the code. Being a webdesigner, usability and accessiblity are my first aims. I've many ideas and many suggestions collected in my to-do list, but being alone, the development would be really slow, maybe even pointless. I would be glad to answer to all questions, technical, conceptual and more... and to explain more in depth how C::NTR::L is working. I know everybody is quite busy, infact i would be really glad also of some little help with some taks. I'm also developing a new interface trying to make C::NTR::L user-friendly for real. But this is another issue that i also would like to discuss about with the list. My idea, maybe pretty ingenuos, is to create a software for audiovisual performances so easy to use also for no-Pd'rs, that one would download Pd (and starting to familiarize with it) because of the interest towards C::NTR::L, or any other user-friendly software - unfortunately i don't see many around. For sure it wouldn't happen with millions of people, but maybe it could help in the spreading of Pd, and OS multimedia creation. further link (still have to update some contents, but....the most is there....) www.thesaddj.com/cntrl www.thesaddj.com/icontrolnature sorry for the very very long e-mail. best -- Marco Donnarumma aka The !S.A.D!

hi Nacho, The paperback is in english and can be purchased here: http://www.buecher-zur-musik.de/assets/s2dmain.html?http://www.buecher-zur-… (unfortunately the language of that book store is german; Though it is sent to Amazon, they don't update their site).
