by Antoine Villeret 20 May '13

20 May '13

hi all, I've just notice [tcpserver] crashes when the 34th client try to connect both iemnet and mrpeach are affected iemnet version send a strange number on the 33th connection (like 2.8686e+07) and crashes on the 34th here is a gdb output for iem : Program received signal SIGSEGV, Segmentation fault. 0x00007fffcdbca746 in tcpserver_connectpoll (x=0x66994c0) at tcpserver.c:503 503 x->x_sr[i] = y; (gdb) watchdog: signaling pd... and for mrpeach : Program received signal SIGSEGV, Segmentation fault. 0x00007fffcddaf585 in tcpserver_connectpoll (x=0xadfc1c0) at tcpserver.c:1113 1113 outlet_float(x->x_sockout, x->x_sr[i]->sr_fd); /* the socket number */ (gdb) watchdog: signaling pd... it happens on ubuntu 12.04 64 bit pd 0.44.2 and SVN update today i'm certainly doing something wrong to get this (like keeping clients connected all the time) but a crash is never welcome... cheers antoine -- do it yourself http://antoine.villeret.free.fr

external: method to convert t_atom to c string.
by J Oliver 20 May '13

20 May '13

Hello all, I need to create a textfile from inside an external and I need to give the computer a path with a message like: path /home/path/file.txt I am therefore creating a method for path with: class_addmethod(testtext_class, (t_method)testtext_path, gensym("path"), A_GIMME, 0); Or should I use A_DEFSYMBOL ? But then how can I read the atom inside the external? I am using: void testtext_path(t_testtext *x, t_atom *s){ char teststring[1000]; atom_string(s, teststring, 1000); post(teststring); } but then I get the following printout: consistency check failed: atom_string 333333@ÿÿÿÿs I'm not sure where to move with this. anybody has any suggestions? best, J Here's the info for atom_string: atom_string void atom_string(t_atom *a, char *buf, unsigned int bufsize); Converts an atom a into a C-string buf. The memory to this char-Buffer has to be reserved manually and its length has to be declared in bufsize. in: http://pdstatic.iem.at/externals-HOWTO/node9.html#SECTION000922000000000000…

Re: [PD] RPI + new canvas position
by Matthew Walsh 18 May '13

18 May '13

Since Raspbian uses LXDE (which uses the OpenBox WM), I used the new-window-positioning fix mentioned here: http://comments.gmane.org/gmane.comp.multimedia.puredata.general/86348 The fix, to pdtk_canvas.tcl, involves changing: set x [ expr $x % $screenwidth - $::windowframex] set y [ expr $y % $screenheight - $::windowframey] to: set x [ expr max($x % $screenwidth - $::windowframex, 0)] set y [ expr max($y % $screenheight - $::windowframey, 0)] On my Pi, it works for both Vanilla and Extended.

I've solved the problem in Pd-extended 0.43.4 loading path /usr/lib/pd-extended/extra/pdp Using this method it's possible to load composed abstractions like pdp_contrast. But in Pd Vanilla 0.43.0-4 pdp have conflicts with ligsl.

OT: raspberry pi
by Patrick Pagano 18 May '13

18 May '13

Hello i just received my first raspberry doo-hickey and i am wondering what distro people are using. I tried the wheezy last night and it seems okay, i installed pd-extended after a few tries I was unsuccessful with getting the CCRMA distro to load onto an 8GB chip i basically would like to have pd with pdp working, supercollider and i assume omxplayer are there any other essentials i should try? i would like to use the pi for receiving network GOs for small video projections on stage or to fire off small videos from other sources [arduino, kinect, wii etc..] thanks in advance for any comments or help Patrick

[PD-announce] CFP - 2nd Int'l Workshop on Musical Metacreation (MUME2013)
by Graeme McCaig 18 May '13

18 May '13

====================== CALL FOR PARTICIPATION ====================== ((( MUME 2013 ))) 2nd International Workshop on Musical Metacreation http://www.metacreation.net/mume2013/ Held at the Ninth Annual AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE'13) Northeastern University, Boston, Massachusetts, USA October 14-15, 2013 ---------------------- Deadline for Paper and Demo Submissions: *** July 1, 2013 *** ====================== We are delighted to announce the 2nd International Workshop on Musical Metacreation (MUME2013) to be held October 14 and 15, 2013, in conjunction with the Ninth Annual AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE'13). MUME2013 builds on the enthusiastic response and participation we received for the inaugural workshop in 2012, which received 31 submissions, 17 of which were accepted (a 55% acceptance rate). This year the workshop has expanded to 2 days. Thanks to continued progress in artistic and scientific research, a new possibility has emerged in our musical relationship with technology: Generative Music or Musical Metacreation, the design and use of computer music systems which are "creative on their own". Metacreation involves using tools and techniques from artificial intelligence, artificial life, and machine learning, themselves often inspired by cognitive and life sciences. Musical Metacreation suggests exciting new opportunities to enter creative music making: discovery and exploration of novel musical styles and content, collaboration between human performers and creative software "partners", and design of systems in gaming and entertainment that dynamically generate or modify music. MUME brings together artists, practitioners and researchers interested in developing systems that autonomously (or interactively) recognize, learn, represent, compose, complete, accompany, or interpret music. As such, we welcome contributions to the theory or practice of generative music systems and their applications in new media, digital art, and entertainment at large. Join us at MUME2013 and take part in this exciting, growing community! Topics ====== We encourage paper and demo submissions on topics including the following: * Novel representations of musical information * Systems for autonomous or interactive music composition * Systems for automatic generation of expressive musical interpretation * Systems for learning or modelling music style and structure * Systems for intelligently remixing or recombining musical material * Advances or applications of AI, machine learning, and statistical techniques for musical purposes * Advances or applications of evolutionary computing or agent and multiagent-based systems for musical purposes * Computational models of human musical creativity * Techniques and systems for supporting human musical creativity * Online musical systems (i.e. systems with a real-time element) * Adaptive and generative music in video games * Methodologies for, and studies reporting on, evaluation of musical metacreations * Emerging musical styles and approaches to music production and performance involving the use of AI systems * Applications of musical metacreation for digital entertainment: sound design, soundtracks, interactive art, etc. Format and Submissions ====================== The workshop will be a two day event including: * Presentations of FULL TECHNICAL PAPERS (8 pages maximum) * Presentations of POSITION PAPERS and TECHNICAL IN-PROGRESS WORK (5 pages maximum) * Presentations of DEMONSTRATIONS (3 pages maximum) * One or more PANEL SESSIONS (potential topics include international and networked collaborations, evaluation methodologies, industry engagement, generative music in art vs. games) Workshop papers will be published in a Technical Report by AAAI Press and will be archived in the AAAI digital library. Submissions should be made in AAAI, 2-column format; see instructions here: http://www.aaai.org/Publications/Author/author.php For complete details on attendance, submissions and formatting, please visit the workshop website: *** http://www.metacreation.net/mume2013/ *** Important Dates =============== Submission deadline: July 1, 2013 Notification date: August 6, 2013 Accepted author CRC due to AAAI Press: August 14, 2013 Workshop date: October 14-15, 2013 Workshop Organizers =================== Dr. Philippe Pasquier (Workshop Chair) School of Interactive Arts and Technology (SIAT) Simon Fraser University Dr. Arne Eigenfeldt School for the Contemporary Arts Simon Fraser University Dr. Oliver Bown Design Lab, Faculty of Architecture, Design and Planning The University of Sydney ---------------------- http://www.metacreation.net/mume2013/ ====================== _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

udp stream audio from gstreamer (to puredata)
by stéfan piat 17 May '13

17 May '13

hello, I try to stream audio (wav) from a rasperry pi with Gstreamer and catch it in puredata with [udpreceive~] I am wondering if this is possible ? To stream I use the following command : *gst-launch-1.0 -v alsasrc device=hw:1,0 ! udpsink host=192.168.2.102 port=5001* when I send the message [info( to [udpreceive~] I can see there is see something coming from the pi but I don't succeed to get any sound... in the pd-window I got the following error message: *udpreceive~: bad header tag (1)* I guess itś related to the blocksize argument and I miss some arguments in gstreamer to communicate ? thanks you for your help stéfan
