[PD-announce] CFP - 1st International Workshop on Musical Metacreation (MUME2012)
by Graeme McCaig 08 May '12

08 May '12

CALL FOR PARTICIPATION ====================== ((( MUME 2012 ))) 1st International Workshop on Musical Metacreation http://www.metacreation.net/mume2012/ Held at the Eighth AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE'12) Stanford University, Palo Alto, California, USA October 9, 2012 ---------------------- Deadline for Paper and Demo Submissions: *** July 6, 2012 *** ====================== We are delighted to announce the 1st International Workshop on Musical Metacreation (MUME2012) to be held October 9, 2012, in conjunction with the Eighth AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE'12). Thanks to continued progress in artistic and scientific research, a new possibility is emerging 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. The workshop will bring together artists, practitioners and researchers interested in developing software and systems that autonomously (or interactively) recognize, learn, represent, complete, accompany, compose or interpret music. In particular, emphasis will be put on systems with real-time aspects, since these are relevant to both art and entertainment communities. 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 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 Format and Submissions ====================== The workshop will be a one day event including: * Presentations of TECHNICAL PAPERS * Presentations of POSITION PAPERS relevant to Musical Metacreation and its future * Presentations of DEMONSTRATIONS * One or more PANEL SESSIONS (potential topics include international collaborations, evaluation methodologies, industry engagement, generative music in art vs. games) For complete details on attendance, submissions and formatting, please visit the workshop website: *** http://www.metacreation.net/mume2012/ *** Important Dates =============== Submission deadline: July 6, 2012 Notification date: August 3, 2012 Accepted Author CRC due to AAAI Press: August 17, 2012 Workshop date: October 9, 2012 Workshop Organizers =================== Dr. Philippe Pasquier (Workshop Chair) School of Interactive Arts + Technology (SIAT) Simon Fraser University Dr. Arne Eigenfeldt The 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/mume2012/ ====================== _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Is it possible to change webcam's resolution in Mac OS?
by Matteo Sisti Sette 08 May '12

08 May '12

Hi, I'm using Pd Extended 0.42.5 and for a series of reasons upgrading is not an option right now. I don't have a Mac but I need my patches to work on Mac OS and Windows. (I can test windows and linux) I don't know if it has been fixed in later versions of GEM, but there's some dreadful bug somewhere in [pix_video], [pix_movement] or [pix_blob] or maybe somewhere else, that causes [pix_blob] to randomly output out-of-range values for x and y (negative values and values a lot greater than 1), both on Windows and Mac. On Windows a workaround that works is to lower the webcam's frame rate AND resolution (I'm not 100% sure the framerate is needed, but the resolution certainly is). I can live (unhappy) with having to do it manually every time, and I can trigger the settings dialog to open by sending the "dialog format" message to [pix_video] (unfortunately the values are not saved) THE PROBLEM is that on Mac OS, the settings dialog that open up with "dialog format" doesn't give any option to change the resolution. I can change the framerate (which is not enough for the workaround to work) but not the resolution. The questions then are: - Is there a way, perhaps somewhere in the system settings in Mac OS, to lower the webcam's resolution? - Does the "dimen" message work on Mac OS? (it doesn't on Linux, at least with my hardware) - Btw Is there a message for setting the camera's framerate? (I don't find it documented) And if anybody has encountered a similar issues (pix_video+pix_movement+pix_blob = out of range values) I'd of course love to know how you have worked around it (or is it worked it around?) Thanks in advance cheers m.

old patch to (automatically) fragment an audio buffer
by João Pais 08 May '12

08 May '12

Hi, I remember that some time ago someone presented a patch that (automatically?) fragments an audio buffer into pieces, based on a [bonk~] analysis. Does anyone know which patch is it, or where to find it? I looked in the archives for several tags, but couldn't find it. Thanks, JoÃ£o

pduino patch help
by Drake Schutt 07 May '12

07 May '12

I've got a fairly simple patch that I got help from someone on the list in building. It just takes midi data from 16 drum pads and routes the bangs to different output pins. The pins then trigger a seperate solenoids with the arduino board. These solenoids hit actual drums. I thought the pd patch was working last week and the [digital 0 0] message box was displaying different numbers when different drum pads were triggered. I then updated the firmata library because I thought I should. The [digital 0 0] box then stopped displaying numbers according to midi input data. Would someone mind looking at my patch and seeing if something is wrong? I don't know a whole lot about pd. I can send it off list, I doubt there's attachments here. Thanks, Drake

[Pd] Compile external with C++ compiler?
by Joe White 07 May '12

07 May '12

Hi all, Thought I might as well ask this here because you guys know everything :) I'm writing an external to be built into an iOS app that's running Pd. The catch is I need to interface with a C++ library within the external. The external builds and runs fine if I'm using the C compiler (in Xcode) but I can't access the C++ library functions. If I switch it to compile in C++ (by changing the objective-c file from .m to .mm) then I can use the C++ library functions but it complains that it can't find 'class_addmethod' *'No matching function for call to 'class_addmethod'* I've tried declaring the setup function as C code like Katja explains on her site <http://www.katjaas.nl/pitchshift/soundtouch~.html>: extern "C" void external_tilde_setup(void) { } But that still didn't seem to work. I was also going through the list and found this thread<http://lists.puredata.info/pipermail/pd-list/2002-02/004485.html> but I'm not sure if it's the right approach. Plus I'm more of an audio guy than programmer :) Any ideas would be much appreciated. Thanks, Joe -- Follow me on Twitter @diplojocus

error, cant load knob on pd 0.43.1
by Roberto Aramburu 07 May '12

07 May '12

Im writing to report this error that i get trying to open a patch i built using pd extended 0.42.5 in Windows 7 As soon as i open the patch i get this error "knob 32 32 0 15 0 0 empty empty empty 0 -8 0 8 -262144 -1 -1 0 1 ... couldn't create" i dont know why, since its not an abstraction but a common [knob] object. I shared the patch with a friend of mine and he gets the same error. Since i dont know if i can attach files and send them to the list, ive uploaded the patch here http://www.mediafire.com/?e3up75n1x7r5bqh
