Chocolate et Coffee
by Pierre Guillot 31 Dec '13

31 Dec '13

Hi everybody, I'm pleased to share my new libraries : Chocolate & Coffee. For the HOA project, I've developed a C library to facilitate the creation of graphical objects for Pure Data and to allow further interactions with the users. My experimentation objects were a VU-meter and a number box for signal. They appeared useful and ergonomic for me so I undertook to extend the list. Quickly : Chocolate is a set of GUIs sometimes already available in PD Vanilla, PD extented or Max with new features (like presets edition) that I hope, you'll enjoy. And it will be a part of a more complex project for the writting of events. Coffee is a set of objects to facilitate the patch creation. The libraries are available for Mac, Windows and Linux and they have been tested on PD extented 0.43 and PD 0.45. Download : https://github.com/pierreguillot/PdEnhanced/releases Feedback are wellcome (for developement questions, the best is to use the git project). I hope you'll find this libraries useful. Bonne année Ps : The C library seems to work very well under Linux. So, if we don't have problems with the other dependencies, we'll be able to offer a Linux version of the Hoa Library very quickly.

Lecture: Audio Feedback and Acoustic Space (Barcelona)
by l'ull cec 16 Dec '13

16 Dec '13

AUDIO FEEDBACK AND ACOUSTIC SPACE (lecture by Massimo Scamarcio) Audio feedback has been used as a tool by numerous electronic / electroacoustic musicians, composers and performers, as well as sound artists. This talk will address some of the potentialities of audio feedback as well as its strong relationship with acoustic space. Massimo Scamarcio will discuss the basics of feedback theory and audio feedback, showing how to trigger and control it using the Supercollider software, and focusing on some of its compositional and performative possibilities. Monday, 16.12.2013, 19:00 h ESMUC. Room 114. Padilla, 155 (Edifici L'Auditori). Barcelona. Metro Marina, Glòries o Monumental. -------------------------------------------------------- web: [ http://lullcec.org ] facebook: [ http://facebook.com/lullcec ] twitter: [ http://twitter.com/lullcec ]

Living Circuits: An autonomous 12 tone serialist composition, in pure data.
by Peter van Haaften 14 Dec '13

14 Dec '13

Greetings, My new work (in pure data) is now available for listening, with accompanying documentation at: www.petervanhaaften.com/livingcircuits.shtml<http://petervanhaaften.com/livingcircuits.shtml> ------------------ An entirely autonomous performing/composing instrument, using 12 tone serialism. Written in Pure Data, an internal variable score defines a semi-fixed structure. A 12 tone pitch matrix is automatically built, and the various transformations, inversions, and retrogrades are triggered to playback via a Euclidean rhythm generator. Audio output is routed back into the system for automated processing and spatialization via scored event triggers, and weighted random number generators. Every performance is unique. -------------------- Thanks for looking! PVH

pdp 0.14.1
by Tom Schouten 13 Dec '13

13 Dec '13

Hi List, An update to PDP: http://zwizwa.be/pd/pdp/pdp-0.14.1.tar.gz 0.14.1: Port SCAF MMX code to x86_64 ABI Revive pdp_opengl (3dp) Bugfixes SCAF (Simple Cellular Automata Forth) is ported to x86_64 ABI. It still uses the old MMX 64bit integer code which makes little sense on x86_64, but at least it works. 3dp mostly works. Some known issues in corner cases (pdp/opengl/doc/examples): - example05.pd : multiple window render contexts causes crash - example06.pd : bug in scaf CA grid -> texture conversion ? The texture feedback also looks a little weird - not as I remember it. Enjoy Tom

Workshop: Feedback as Space / Space as Feedback (Barcelona, 14/15.12.2013)
by l'ull cec 13 Dec '13

13 Dec '13

(apologies for cross-posting) We have 4 seats left available for this workshop that is to start tomorrow. ------------------------------------------------------------------------- FEEDBACK AS SPACE / SPACE AS FEEDBACK From the rhythmic, flanging reflections of tiny, narrow corridors to the long, deep reverberations of large halls and churches, space has always had a deep and inseparable relationship with sound. Sound carries with it the identity of the acoustic space in which it occurs: it travels through air, bouncing on walls and obstacles, waves of acoustic energy being absorbed, reflected, and progressively shaped by the characteristics of the room. This workshop focuses on the investigation of space and will use the SuperCollider software (if you use PureData or MAX/MSP, read further below). Participants will be shown the basic techniques for analysing sound and extracting meaningful data such as pitch, amplitude, spectral centroids, frequency peaks and more. The Fast Fourier Transform will also be discussed. An important part of the workshop will be to use audio feedback as a way to investigate space and as a tool for systemic construction. Audio feedback is space-made-sound, and as such, techniques for triggering and controlling it will be introduced and discussed. The workshop will then focus on the acoustic spaces and resonances of common-found objects. By means of piezo contact mics, miniature microphones and other transducers, the "space" of the objects will be explored and investigated, resonant frequencies will be measured and feedback structures will be set up between the objects themselves and also between the objects and the acoustic space of the room. Level: Beginner/Intermediate. Some previous exposure to working with SuperCollider is preferred, but beginners are welcome. The workshop will use SuperCollider mainly, but MAX/MSP and PureData patches will be provided for most of the techniques that we will cover. Tutor: Massimo Scamarcio [ http://massimoscamarcio.com/ ] Language: English Some materials will be available at the venue (piezo contact mics & miniature mics, mini-speakers, some common objects) Participants should bring their own computer with a recent release of SuperCollider installed. Audio interfaces are a plus but not required. Participants are also encouraged to bring their own materials (mics, preamps, etc) & objects (can be anything – from glass vases to plastic pipes, bottles and everything in-between). Dates: Saturday 14.12.2013, 12:00-14:30h, 16:30-20:00h Sunday 15.12.2013, 12:00–14:30h, 16:30-:20:00h Location: Joan Casas, 2. Metro Glòries.

Workshop: Complex Dynamical (Eco-)Systems Based on Nonlinear Feedback Networks: Theory and Practice (Barcelona, 7-8/12/2013)
by l'ull cec 03 Dec '13

03 Dec '13

(apologies for cross-posting) COMPLEX DYNAMICAL (ECO-)SYSTEMS BASED ON NONLINEAR FEEDBACK NETWORKS: THEORY AND PRACTICE In this workshop, complex dynamical feedback systems for human-machine interaction performance, autonomous sound installations and non-conventional sound synthesis will be discussed and put to practice. The workshop will be divided into two main parts: First, a theoretical part will cover the properties of feedback systems from a systemic and cybernetic perspective within the framework of emergent and complex phenomena, along with theoretical concepts related to such an approach for creative practices. In the second part, Dario Sanfilippo will present some of his works and techniques and such systems will be implemented through the Pure Data programming environment trying to give the possibility to each participant to personalise their own systems. During the implementation process, technical and theoretical aspects of the techniques used will also be discussed. Requirements: A laptop with the last version of Pure Data-extended installed and any kind of microphone. Tutor: Dario Sanfilippo Dates: Saturday 07.12.2013, 19:00-21:30h Sunday 08.12.2013, 12:00–14:30h, 16:30-:19:30h +info: [ http://lullcec.org/en/2013/workshops/eco-sistemes-dinamics-complexos-basats… ] ------------------------------------------------------------------------------------ web: [ http://lullcec.org ] facebook: [ http://facebook.com/lullcec ] twitter: [ http://twitter.com/lullcec ]
