LoMus 2010 | Submissions was extended to the april 15th
by Thierry Coduys 02 Apr '10

02 Apr '10

LoMus 2010 __________________________________________ Sorry for multiple and cross postings __________________________________________ The dead line for software submission was extended to the April 15th __________________________________________ In search of open-source software for musical and intermedia creation For its third edition, Lomus 2010 invites music and audio open-source software creators to submit original projects that either directly or indirectly contribute to musical creation. In regard to one of the 2 themes for JIM's edition : "The musical work and heterogeneity : the problem of mixity", the LoMus contest will particularly encourage sonic/musical softwares integrating or hibridizing with other media. Though, this theme is not restrictive. A prize will be awarded to open-source sofware that prove to be not only innovatory but also inventive in the present context of music and audio creation. Calendar Call for submissions : February 4th 2010 Submission deadline : April 15th 2010 Admission notification : May 1st 2010 JIM Awards Ceremony : May 20th 2010 info : concours.afim-asso.org JIM2010 : http://jim.afim-asso.org/ocs/index.php/jims/index __________________________________________ À la recherche des logiciels libres pour la création sonore et intermedia Pour sa troisième édition, Lomus 2010 s’adresse à tous ceux qui s’aventurent dans le développement de logiciels libres musicaux ou de logiciels libres qui peuvent contribuer au processus de la création musicale. En regard d'un des 2 thèmes mis en avant lors de cette édition des JIMs : "L'Œuvre musicale face à l'hétérogène : problématique de la mixité", le concours LoMus encourage plus particulièrement les contributions intégrant ou s'hybridant avec d'autres médias. Ce thème n'est cependant pas restrictif. Un prix sera remis aux logiciels qui font preuve non seulement d'innovation, mais notamment d'inventivité face aux enjeux actuels de la création musicale. Calendrier Appel à soumissions : 4 février 2010 Soumission des logiciels : 15 avril 2010 Notification d'acceptation : 1 mai 2010 Remise du prix lors des JIM : 20 mai 2010 info : concours.afim-asso.org JIM2010 : http://jim.afim-asso.org/ocs/index.php/jims/index

dynamic gui masking problem
by Roman Haefeli 02 Apr '10

02 Apr '10

Hi all I'm trying to create a GOP abstraction for selecting an item from a list. The cool thing about GOP is, that iemguis are still visible, even if they are moved outside the GOP area. However, the problem I'm facing is that they are masked by other objects in the patch, when they are moved to area of some other object. A Solution: Dynamically creating objects on the fly makes them appear above all other objects in the patch.Unfortunately I couldn't figure out a way to delete them to make them disappear, when they're not needed anymore. Probably there is another way of tweaking the z-index of objects? Or is there a way to dynamically delete objects without having to 'vis' a canvas and putting it into edit mode (and without printing errors to the console)? Attached is an example patch to illustrate the masking problem. Roman

Loop object
by Jerome Covington 02 Apr '10

02 Apr '10

Looking at the [loop~] help example but am unable to create any noise. When I click on array 2 in play mode the following is logged in the console. error: conflicting block~ objects in same page play~'s error: no such array '0-table' play~'s error: no such array '1-table' play~'s error: no such array '2-table' play~'s error: no such array '3-table' Is there an issue with this example? (Entirely possible that it is perfect, and that I am to blame.) Are there other useful examples of the [loop~] object? -- Regards, Jerome Covington . . . . : . . . . : "define audio development"

latency solutions... and then some
by Jeffrey Concepcion 02 Apr '10

02 Apr '10

Hi, y'all. i'm starting to get the hang of pd now (about a year in to it), my main interest in using pd would be to create effects for processing my instruments (primarily electric bass and acoustic drums) and accessing them via an arduino footswitch and/or an arduinome i plan on making. My problem is that i can't achieve a low enough latency to have a useful patch in a live performance setting. so i have a few questions, if i can get as many of you to answer them, maybe we can have a standard setup for this type of processing (i apologize if this is common knowledge to many pders): - in terms of processor capacity, hardware, and sound card configuration, what would be the minimum requirements to achieve unnoticeable latency (not hear the affected signal as a slap-back type of effect)? i've read that 11ms can be achieved and is unnoticeable. - what is your setup for live processing? what do you think is the ideal setup for live processing? (i'd like you read Miller's thoughts on this) - what do you think will be the next big step in making sound art, be it musical, online group performances, new interfaces, whatever? (kind of a personal question, i know, but bear with me) My thoughts on the last question: i'm intrigued by photonics<http://en.wikipedia.org/wiki/Photonics>, from what i understand, the amount of information handled is gargantuan when compared to electronics, and that would mean that electronic musicians (or would we then be photonic musicians?, sounds catchy) would no longer have to consider the limitations our equipment when composing/performing and our imagination would truly be the only limitation. sorry if i seem romantic about it, but it seems like such an interesting possibility. here<http://emusician.com/futuretech/photonics_technology_electronic_musicians/>'s an article by EM -- www.avmachinists.org Puerto Rico based Art Collective/ Non-Profit Org

[buzz~] -- bandlimited pulse train
by Matt Barber 02 Apr '10

02 Apr '10

Since we've been talking about bandlimited signals, attached is an approach to an abstraction which can be used like the csound opcode buzz -- I just threw it together today and would of course welcome any improvements. Matt

pix_buffer question

I am assuming this is more or less > how pix_delay works. instead of that, once it goes beyond 1000, start over at 0. then whenever you want to have a certain previous image, such as 666 frames ago, instead of saying that you want frame 1000-666=334, say you want frame N-666 mod 1001, that is, current frame number | [- 666] | [mod 1001] | ... i say 1001 just because you say that the first index is 0 and the last index is 1000, which means 1001 different indices, not 1000. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

GEM: Two particle systems in one patch interfering
by Johannes Paar 02 Apr '10

02 Apr '10

Hi, I have a problem with two particle systems in my patch. If in one of them I change gravity, source and killold properties, it affects the second one somehow. But they are separate gemlists and are not connected in any way. How can I fix that? Thanks, Joh
