Re: [PD] vbap 1.0.3.2 fails when sent longer "define_loudspeakers" messages
by Hans-Christoph Steiner 07 Jan '13

07 Jan '13

Hey Zach, Looks like you've gone deep into it :) Sounds like those MAX macros are set because the code can't currently handle longer lists. I won't have time to look at this for a while. Could you post a bug report to the bug tracker (Help menu --> report bug) with the info in this email? Also it might be worth your while to see if anyone has tried this when using this object in Max/MSP. Its the same code. .hc On 01/07/2013 09:45 AM, Zack Settel wrote: > Hi Hans-Christoph, > > Thanks for your previous reply before the holidays. > > Just to refresh the subject: > > using Pd-0.42.5-extended.app, Pd-0.43-3.app, and Pd-0.43.4-extended-20121101 > on OSX 10.6x and 10.7x, > > vbap 1.0.3.2 crashes when sent longer "define_loudspeakers" messages > > > the PD console displays: vbap: Loudspeaker setup configured! pd: getbytes() failed -- out of memory vbap: Configure loudspeakers first! > and the program crashes. > > > (It appears to be failing in the "vbap_matrix" method.

Im trying to connect Arduino via bluetooth to libPd / PdDroidParty running on my android. Does the comport could be used for that communication ? Do anyone already try this combination?

Circular scrolling in pd
by James Dunn 07 Jan '13

07 Jan '13

Hi, I'm trying to implement circular scrolling with the trackpad in pd and am approaching it by dividing a circle into segments and trying to detect when the mouses moves from one segment to the other. At the moment I can only detect 4 segments (basically just the zero crossings) which is not really accurate enough. How would I go about detecting the boundaries of the 12 segments in the attached patch (circscroll.pd)? Eventually I want to detect speed and direction too - but perhaps there is a better approach? any advice welcome. thanks, james

[PD-announce] PERFORMA 2013 – Conference on Musical Performance Studies
by James Correa 07 Jan '13

07 Jan '13

The Graduate Studies Program of the Instituto de Artes of the Universidade Federal do Rio Grande do Sul (UFRGS), in collaboration with the Brazilian Association of Musical Performance (ABRAPEM), the University of Aveiro and INET-MD (Institute of Ethnomusicology - Centre for Music and Dance Studies), will host PERFORMA, a conference on performance studies, from May 31st through June 2nd, 2013 in Porto Alegre, Brazil. The keynote-speakers will be Prof. Eric Clarke, from the University of Oxford, Prof. Paulo Assis, from the University Nova of Lisbon/Orpheus Institute (Ghent), and Prof. Luca Chiantore, from Musikeon/Escola Superior de Mu?sica de Catalunya. This conference seeks to generate and present new perspectives on musical performance through interdisciplinary dialogue. The main theme for the 2013 edition will be artistic research and musical performance. Submissions are now invited; we particularly welcome submissions that address artistic research as a methodological outlook and that present practice-based inquiry. The conference will also consider proposals on any aspect of performance studies such as performance science, philosophy and performance, performance practice, music pedagogy, musicology, ethnomusicology and performance analysis. We welcome abstracts of a maximum of 350 words for: * Paper presentations (max. length 20 minutes) * Pre-formed Panels: Please submit abstracts with each named speaker and their institutional affiliation. Panels should last 1 hour and 30 minutes. * Lecture-Recitals: should last from 30 to 45 minutes. Proposals submissions should specify exact length and be accompanied by a short curriculum of the presenter. * Posters. We do not require a pre-defined proposal format, but we recommend that submissions include information on context, aims, methods and results. Abstracts should be sent to performa(a)ca.ua.pt <mailto:performa@ca.ua.pt>. We also welcome proposals for 20-minutes long performances, which will be presented in a shared recital format. Applicants are invited to submit video/audio recordings of the proposed performance. The video should be posted on Youtube (please note that you can select private, unlisted or public viewing) and a link to the video should be sent to fialkow(a)terra.com.br <mailto:fialkow@terra.com.br>, accompanied by the name(s) of the performer(s), institutional affiliation, a list of the works to be performed, and a short bio. Please note that percussion equipment will not be provided. The submission deadline is January 14th, 2013. General enquiries (registration, travel, lodging) should be sent to lucnoda(a)gmail.com <mailto:lucnoda@gmail.com>. Abstracts and performance proposals will be reviewed by a panel, and presenters will be advised as to their acceptance or otherwise by mid-February, 2013. The deadline for the submission of proceedings articles (accepted authors only) is March 18th, 2013. _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Re: [PD] VLC with PD-extended

hi, it's always good to use once of the various mailing lists to ask questions regarding Pd. this allows other people to benefit from problems.

Tcl/Tk 8.6.0
by michael noble 07 Jan '13

07 Jan '13

Archlinux has bumped Tcl/Tk to the recently released 8.6.0 version. I'm in no hurry to upgrade, but was wondering if the new version is likely to cause problems for Pd in the same way as the move from 8.4.0 to 8.5.0? thanks Michael

by Hans-Christoph Steiner 07 Jan '13

07 Jan '13

Hey all, Its time to start talking about the next PdCon! I was just talking with Golan Levin and Dan Wilcox about the possibility of having the next PdCon at Carnegie Mellon University in Pittsburgh. One possibility is having it coincide and partner with a local music and new media festival in the first week of october: http://www.via-pgh.com/festival/2012/ Is that workable for people? Any other discussion about other possible locations? .hc
