Re: [PD] pd-extended license WAS: Keyboard shortcuts for "nudge", "done editing"
by Hans-Christoph Steiner 12 Oct '11

12 Oct '11

Wow, I guess I was wrong about this being off topic. It seems people have a lot of questions about this. In the case of a GPL project including a BSD code, there is not a separate license. Only the copyright holder can change the license. It is just that the BSD license allows you to add additional restrictions. The GPL adds one restriction: whenever you give someone the software, you have to also give them the source code. So if you were going to include Pd-extended in your OS as a whole, you have to treat all the code as GPLv3. list-abs is a library included in Pd-extended. It is released under a BSD license. If you download list-abs by itself and package that, then it is not Pd-extended. So its BSD. .hc On Sep 28, 2011, at 10:27 AM, Ludwig Maes wrote: > If source code and binaries can have seperate licences, what about > object files or intermediate representations in the compiler (GIMPLE > etc)? > ... > > On 28 September 2011 15:10, Hans-Christoph Steiner <hans(a)at.or.at> > wrote: > > On Sep 28, 2011, at 1:47 AM, Chris McCormick wrote: > > Hi Hans, > > > On Tue, Sep 27, 2011 at 05:32:14PM -0400, Hans-Christoph Steiner > wrote: > > On Sep 27, 2011, at 4:53 PM, Mathieu Bouchard wrote: > > Le 2011-09-27 à 16:41:00, Hans-Christoph Steiner a écrit : > > No one is talking about relicensing.

how to change bp~ frequency at sample rate?
by Menno van der Woude 10 Oct '11

10 Oct '11

Hi all, working on patches that will be controlled by video analysis (through OSC messages), I am wondering how to change the frequency (second inlet) for [bp~] in realtime. The problem is: connecting a [line] object or number object to this inlet will result in clicks and pops when the line is moving very fast or changes are rapid. Is there a way to change the frequency for [bp~] at sample rate? Or should I use another object to achieve this kind of realtime cutoff/resonance changes? I kind of like the simplicity of [bp~] as opposed to for example [cpole~], which is beyond my current grasp of this material... Thanks, menno

Re: [PD] Variable number of objects?
by Ingo 03 Oct '11

Well, as I said in my case the voices are very complex. There are hundreds of audio objects in each voice. It takes a lot of time to adjust all of the signal flow and reallocate the memory I guess. Control objects shouldn't be such a big problem. Ingo ________________________________________ Von: Ludwig Maes [mailto:ludwig.maes@gmail.com] Gesendet: Mittwoch, 28.

pix_video not working on Mac OS 10.6 ?
by rene beekman 01 Oct '11

01 Oct '11

I'm having problems getting pix_video to work with the build-in iSight camera on my MacBook. There is no video in the gemwin, just a white rectangle. When I send it a message to open the control panel, GEM hangs (it seems only GEM hangs, I get the beach ball when I hover over the GemWin, but can still move and edit the Pd patch) I've got this on 2 different machines, one 2007 black MacBook and one white 2010 machine. Both run 10.6.8 with latest updates applied. Does anyone else have this problem? Found a solution or even just a work-around? This is coming at the worst of times when tomorrow I need to start teaching a motion capture course...

sigmund~
by Benoît Fortier 30 Sep '11

30 Sep '11

Hello all, I'm using the sigmund~ object to get amplitude and pitch information for the loudest peaks of a signal (see the sinusoid-tracking help patch, which can be found in the sigmund~ help patch). Out of that information, I want to create, let's say, 5 midi notes corresponding to the 5 loudest peaks of the signal. How would you transform the peak amplitude outputs of sigmund, which are linear, into midi velocities in order to make those 5 notes sound with the same relative amplitude that they have in the analysed signal? It might be a stupid question but what are those linear peak amplitude values exactly? Do they have any unit? More generally, can you give me any good reference, preferably online, that explain in details the physic and mathematic behind sound amplitude? I manage to work many things out by myself but i have to admit that my actual understanding of it is a little bit superficial. By the way, I have a good background in physic and mathematic so don't hesitate to suggest me more advanced readings. Thank you! I've learned a lot from you already just by reading the list. Benoît

30 Sep '11

(Apologies for cross-postings, French version below) Call for Projects 2012-2013: Musical Research Residency Program Submission Deadline: October 14, 2011 (Midnight Paris Time) Details and submission procedure: http://www.ircam.fr/875.html?L=1 The third edition of Ircam's Musical Research Residency program is now open for online submissions for the 2012-2013 school calendar. Ircam (Institute for Research and Coordination in Acoustics and Music) offers experimental environments where composers/artists strive to expand their artistic experience at one end, and scientists aim at extending research and technological paradigms for new artistic expressions. Such interactive process is called Musical Research. For its third edition, Ircam is inviting composers and artists to submit projects for the 2011-2012 Musical Research Residency program. The program is open to international artists, regardless of age or nationality, who wish to carry experimental research using Ircam's facilities and extensive research environment. Submission is online only and each project will be evaluated by an international panel of experts including researchers, composers, computer musicians and artists. Upon nomination, each candidate will be granted a residency at Ircam during a specific period (three to six months) and in association with a team/project at Ircam. In addition, laureates receive an equivalent of 1200 Euros per month to cover expenses in France. ------------ Appel à projet 2012-2013: Résidence de Recherche Musicale Date limite de candidature: 14 Octobre 2011 Plus d'information et procédure de candidature: http://www.ircam.fr/875.html L’Ircam (Institut de recherche et coordination acoustique/musique) offre un environnement unique pour l’expérimentation, permettant aux compositeurs d’étendre leur expérience musicale et de repenser leur pratique à travers les concepts et idées liés aux développements des nouvelles technologies les plus récentes. Ces technologies sont le résultat des défis posés aussi bien par les impulsions artistiques que par les nouveaux domaines de recherche explorés par les équipes scientifiques. À l’Ircam, ce processus interactif est appelé “Recherche musicale”. La troisième édition du programme de résidences de recherche musicale est ouverte aux artistes internationaux, sans condition d’âge ou de nationalité, qui souhaitent conduire un projet de recherche musicale en bénéficiant des facilités matérielles proposées à l’Ircam et de la richesse de son environnement de recherche. Les candidats seront choisis selon un processus de sélection faisant appel à l’expertise de chercheurs et artistes internationaux. Les lauréats vont bénéficier d'une résidence à l’Ircam pour une durée de trois à six mois en lien étroit avec les équipes de recherche de l’Ircam. Le candidat recevra une indemnité forfaitaire équivalente de 1200 euros par mois pour couvrir ses frais pendant sa résidence en France.
