HOA Library : new release
by Pierre Guillot 24 Jul '14

24 Jul '14

Hello, (Apologies for cross-posting) The CICM is pleased to announce the new release of the HOA Library that includes 3D rendering and Linux support. The HOA library (High Order Ambisonics) is a collection of C++ classes and a set of FAUST functions (http://faust.grame.fr/) destined to sound spatialization. The HOA library allows musicians and composers to synthesize, transform and render sound fields in a creative and artistic way. It aims facilitating the understanding and the appropriation of key concepts of Ambisonics. It offers original processing like diffuse sound field synthesis, perspective distortion or spatial filtering and new graphical interfaces. The library is available for Pure Data, Max and as VST plugins. The HOA library is free, open-source and made available by the CICM, the centre of research on musical composition and computer science of the University Paris 8. The project has been developed as a part of the LABEX Arts H2H at the MSH Paris-Nord and the plate-forme Arts-Sciences-Technologies. Informations and download : http://www.mshparisnord.fr/hoalibrary/en/ Feedback and comments are welcome. The CICM team. Bonjour, (Avec nos excuses pour les envois multiples) Le CICM est heureux d'annoncer la nouvelle version de la bibliothèque HOA qui comprend le rendu 3D. La bibliothèque HOA (High Order Ambisonics) est une collection de classes C++ et un ensemble de fonctions FAUST (http://faust.grame.fr/) destinés à la spatialisation du son. La bibliothèque HOA permet aux musiciens et compositeurs de synthétiser, transformer et restituer des champs sonores de façon créative et artistique. Elle vise à faciliter la compréhension et l'appropriation des concepts clés de l'Ambisonie. Elle propose des traitements originaux comme la synthèse de champ diffus, la distorsion de perspective ou le filtrage spatial ainsi que de nouvelles interfaces graphiques. La bibliothèque est disponible pour Pure Data, Max et sous forme de plugins VST.

pd extended 43.4 cannot drag in OSX
by Wilfred de Zoete 24 Jul '14

24 Jul '14

From one day to another Pd-extended 43.4 stopped working. I can make a new object but I cannot drag it to another location. They are stuck on the canvas where I spawned them. They do not even stick on the mouse. Making the object freezes them directly on the canvas. I already tried to reinstall. I am running OSX 10.8.5 and did not change anything to the system since last operation. I also closed all windows and rebooted and I made new patches but the problem persists. Does anyone recognize this problem? It's very frustrating just when I need to make a big patch full of mathematics for a big project... Cheers, Wilf

[PD-announce] Neanderthal electronics meets Biophysical music - summer events in Estonia
by Marco Donnarumma 23 Jul '14

23 Jul '14

(sorry for possible x-post) Dears, hope to find you well. Here to inform you about this humble and exciting Estonia tour Derek Holzer and myself are starting today and the ways you can join us. The tour includes an artistic residency in a remote spot, a one-day bus tour to play music in abandoned villages, and a double workshop on Soundboxes and Biophysical music performance. Soundboxes homepage: http://macumbista.net/?page_id=1897 Xth Sense homepage: http://res.marcodonnarumma.com/projects/xth-sense \\\ Artistic Residency at MAAJAAM Valgamaa, EE. - The residency will serve to develop new writing towards the realisation of a new musical performance for body technologies to be premiered at Spectrum, NYC, this October. MAAJAAM is a project space in an old farm in Estonian countryside where art meets technology. Substituting the urban environment with a hilly rural landscape allows us to observe technology in it’s pure form and analyze it’s connections to us and the nature. \\\ Olematute kylade projekt / Project for Non-existent Villages Võru, EE. - One-day tour playing electro-acoustic and biophysical music across several abandoned villages in the Estonian countryside. Expect some modular and visceral sounds resonating crackling walls: http://macumbista.net/?page_id=482 http://marcodonnarumma.com/works/ominous/ Audience, curators and artists travel together on a bus throughout a whole day of sound, silence, ghost houses and unexpected acoustics. Those villages are considered as null pointers; those points existing on maps and in cultural memory but which have lost the objects being refered to. Participating artists excavate embedded meanings in these culturally changing environments and search for intersections of traditional and contemporary cultural practices. Book a spot for on the bus for 1 Euro by emailing to buss(a)taavisuisalu.com. \\\ Soundboxes + Xth Sense workshops Tallinn, EE. Intensive two days crash course on building and making noise with the Soundboxes handmade electronics, and the Xth Sense biophysical wearable instrument. http://www.kultuurikatel.ee/makerlab/event/soundboxes-workshop-with-derek-h… http://www.kultuurikatel.ee/makerlab/event/xth-sense-make-your-own-biophysi… hope to see some of you there! best wishes, -- Marco Donnarumma Performer, body tinkerer, teacher and writer. #soundandmusic #biotech #freeculture EAVI - Goldsmiths, University of London ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Portfolio: http://marcodonnarumma.com Research: http://res.marcodonnarumma.com _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at http://lists.puredata.info/listinfo/pd-announce

nightime mode?
by Julian Brooks via Pd-list 23 Jul '14

23 Jul '14

Hi all, I'm wondering how tricky it would be (relative I know) to invert Pd's colour scheme: black canvas, white boxes; text, cables, etc? This would be for projecting the screen for gigs'n'stuff - I think white on black just looks better (relative again of course) in such environments. I know that via the [hcs] lib I can get at some of the tcl.tk settings but I don't want to have to manually do it every time I open a new/sub-patch. Regards to all, Julian

I've seen a number of different > approaches to this situation. first of all, the best place to ask such questions is the pd-dev mailinglist [1]. imho, the best practice is: - setup a clock-callback that converts the data from your representation to an atom-list and then outputs the data. - in your reading thread trigger the clock in a protected way: sys_lock(); clock_delay(x->x_clock, 0); sys_unlock(); - this will call the clock asap within the main thread of Pd. fmadsr IOhannes [1] http://lists.puredata.info/listinfo/pd-dev

Utilities for synchronising the timing and data of Pure Data patches on a network.

Hi, https://github.com/chr15m/pd-net-sync Open netro-help.pd and netsync-help.pd on two machines on your LAN. Very alpha. There are probably a ton of bugs. Cheers, Chris. -- http://mccormick.cx/

Pd and SQL
by Roman Haefeli via Pd-list 22 Jul '14

22 Jul '14

Hi The few times I had to interface Pd with MySQL, I decided to use [shell] and cobbled together some queries sent to mysql command. While I think that is probably not the most elegant approach, I'd like to ask the community how you dealt with Pd and MySQL, or SQL in general, or even Databases in general. There are certainly many other ways to achieve data retrieval from databases within Pd, I am also thinking of ways that offload the talking to the database to other technologies/languages like PHP, bash, pyhton, etc. Then you have plenty of ways to interface Pd with those. I'm thinking of RESTful (purest_json), web (http* from mrpeach), still bash. I wonder what people decided to use in the end and what they found to be working well. Any success or failure stories to share? Roman

by Alexandre Torres Porres via Pd-list 22 Jul '14

22 Jul '14

Hi there, I was treating this in a different mail thread, sorry, but let me go ahead and start this one. questions 1- Why can't I get vanilla 0.45 from "apt-get"? I get 0.43 :P 2- I downloaded from miller's site and have 0.45 extracting and alive, I'm running it from a folder at pi/home, but how do I put it in the menu bar? Really linux noobs here... 3- Pd 0.45 is complaining about "ALSA input_error (snd_pcm_open): no such file & directory, but it still works making noise and all. What does it mean, how do I fix it? Thanks
