What OS? What sound device? What steps did you do to make it happen? etc etc etc If it's on macOS, this can happen after putting the machine to sleep and waking it up. It's a warning that the current Portaudio stream was closed which can also happen when a connected device is unplugged. Previous to 0.49, Pd simply hard froze when this happened... > On Feb 26, 2019, at 5:11 PM, pd-list-request(a)lists.iem.at wrote: > > Date: Tue, 26 Feb 2019 17:10:34 +0100 > From: Maximiliano Estudies <maxiestudies(a)gmail.com <mailto:maxiestudies@gmail.com>> > To: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > Subject: [PD] error -9988: Invalid stream pointer > Message-ID: > <CAF358wThoNNuZuz-sMwzSQWf6fmvyf0wgZ2tUSRwMpJBQi0vOg(a)mail.gmail.com <mailto:CAF358wThoNNuZuz-sMwzSQWf6fmvyf0wgZ2tUSRwMpJBQi0vOg@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Hello List, > > A couple of days ago I started getting this error message: > > error -9988: Invalid stream pointer > audio device not responding - closing audio > you may need to save and restart pd > > I'm not sure how to reproduce it.

Query if Pd is in Edit mode for a GUI
by Alexandre Torres Porres 26 Feb '19

26 Feb '19

Hi, how can I query Pd to know it's in Edit mode so I can change the appearance looks of a GUI? The idea is to show the inlets only when in Edit Mode. This would be necessary for [comment] and [scope~] in cyclone. But if it's impossible, I'm fine with that. cheers

25 Feb '19

ICAD 2019 — Call for Student ThinkTank Appilcations (Student Research Consortium) 25th International Conference on Auditory Display Northumbria University, Newcastle-upon-Tyne, UK June 23–27, 2019 https://icad2019.icad.org/ Date: Sunday June 23rd, 2019 Time: 9:00 AM - 6:00 PM Applications due: Friday March 29th, 2019 The Student ThinkTank (Student Research Consortium) is a full day meeting for students doing Graduate or Undergraduate work on auditory display. It will be held on June 23rd. Selected students will give formal presentations and have the opportunity to discuss research ideas and problems with fellow researchers in the field. The program will also include career-related activities. The ThinkTank is your chance to set a whole roomful of auditory researchers to work on your particular research issue, to help you choose which method, tool, technique, or principle to use to save you from heading down a dead end. Besides providing thoughtful insights into your particular project, the ThinkTank will foster friendships and networks among fellow students and researchers that are essential in an international community for auditory display. Financial assistance will be available for selected applicants from US Universities from ICAD and the NSF. Any registered ICAD participants can join as an observer free of charge. If you’d like to attend as an observer, please send an email to icad2019thinktank(a)icad.org How to apply To apply please submit the following 4 items: 1. Cover Letter Your cover letter should include the following information: * Statement of interest in participating in the ThinkTank. * Full name of the School and Department in which you are studying. * Current stage in your academic program (e.g., completed MS, 2 years into PhD). * Name of the supervising professor. * Your full contact information: address, phone number, and email address. * Title of the research and keywords pertinent to the research. * The URL of your web page (if any). 0. 2. Two-page Research Interest Summary The body of the research summary should provide a clear overview of the research that you have already conducted; is in the process of completing; has planned, or ideas for research that you would like to pursue. The statement should discuss the relevance and potential impact of the research on the field and discuss its broader impact in the world. You are encouraged to include the following sections: * Introduction and problem description. * Brief background and overview of the existing literature. * Goal of the research. * Current status of the research. * Preliminary results accomplished, if any. * Broader Impact of this research. * Open issues, topics to be discussed at the ThinkTank, and expected outcomes from participating in the ThinkTank. For example, you might want to discuss choosing the right tools and techniques, to choosing research topics, to how to organize your thesis, to philosophical or aesthetic issues – anything where you could benefit from the perspectives and experience of other students and experts. 3. Letter of Recommendation Enclose a letter of recommendation written by your Graduate Advisor/Thesis Advisor/Supervisor. Your advisor/supervisor is asked to verify that you are a graduate student, working in the area of sonification or auditory display. (In case of undergraduate student’s submission, please verify the enrolled student status and include information about the undergraduate research project.) Advisors are also encouraged to include an assessment of the current status of your research and an indication of the expected date of its completion. In addition, your advisor is encouraged to indicate what she/he hopes you would both gain and contribute by participating in the ThinkTank. 4. Curriculum Vitae (CV) Please prepare a 1-page CV that relates your background, relevant experience, and research accomplishments. Selection and Presentation: Up to 15 proposals will be selected for formal presentation and “think-tanking”. The selected problems will be representative examples of a widespread problem or will be particularly interesting or challenging (as determined by the expert Panel). Each participant will prepare a 15-minute presentation for all ThinkTank attendees. The Panel will present a report on the ThinkTank in the ICAD 2019 conference program. All those who submit a problem may participate in the ThinkTank to watch the presentations and join in the discussions; however, only the selected submissions will be able to make a formal oral presentation. Even if your problem is not selected you will leave with a sense of what other students are doing and how they are approaching problems in auditory display, as well as new friends to talk about your project with during the rest of the ICAD 2019 conference and in the future. If your problem is selected you may also leave with the breakthrough you need! ThinkTank Panel: The ThinkTank Panel comprises several international researchers who work across a range of disciplines covered by auditory displays. The confirmed Panel members are: * Dr. Areti Andreopoulou (chair), University of Athens * Dr Bruce Walker, Georgia Institute of Technology * Dr. Matti Gröhn, Stereoscape, Finland * Derek Brock, United Stated Naval Research Lab * Dr. Myounghoon Jeon, Virginia Tech * TBC * TBC * How to Submit: Please email your proposal by March 29th, 2019 to the ThinkTank chair at icad2019thinktank(a)icad.org If you have any questions, please feel free to email us. -- -- Areti Andreopoulou, PhD Assistant Professor in Music Technology Laboratory of Music Acoustics and Technology (LabMAT) Department of Music Studies National and Kapodistrian University of Athens labmat.music.uoa.gr <http://labmat.music.uoa.gr/> _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

by Kıvanç Tatar 25 Feb '19

25 Feb '19

=================== MUME 2019 - EXTENDED DEADLINE: MARCH 24, 2019 =================== ====================== 3rd CALL FOR SUBMISSIONS ====================== ((( MUME 2019 ))) The 7th International Workshop on Musical Metacreation http://musicalmetacreation.org June 17-18, 2019, Charlotte, North Carolina MUME 2019 is to be held at the University of North Carolina Charlotte in conjunction with the 10th International Conference on Computational Creativity, ICCC 2019 (http://computationalcreativity.net/iccc2019). === Important Dates === EXTENDED Workshop submission deadline: March 24, 2019 Notification date: April 28, 2019 Camera-ready version: May 19, 2019 Workshop dates: June 17-18, 2019 ====================== Metacreation applies tools and techniques from artificial intelligence, artificial life, and machine learning, themselves often inspired by cognitive and natural science, for creative tasks. Musical Metacreation studies the design and use of these generative tools and theories for 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 intends to bring together artists, practitioners, and researchers interested in developing systems that autonomously (or interactively) recognize, learn, represent, compose, generate, 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. Topics =========================== We encourage paper and demo submissions on MUME-related topics, including the following: -- Models, Representation and Algorithms for MUME ---- Novel representations of musical information ---- Advances or applications of AI, machine learning, and statistical techniques for generative music ---- Advances of A-Life, evolutionary computing or agent and multi-agent based systems for generative music ---- Computational models of human musical creativity -- Systems and Applications of MUME ---- Systems for autonomous or interactive music composition ---- Systems for automatic generation of expressive musical interpretation ---- Systems for learning or modeling music style and structure ---- Systems for intelligently remixing or recombining musical material ---- Online musical systems (i.e. systems with a real-time element) ---- Adaptive and generative music in video games ---- Generative systems in sound synthesis, or automatic synthesizer design ---- Techniques and systems for supporting human musical creativity ---- 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. -- Evaluation of MUME ---- Methodologies for qualitative or quantitative evaluation of MUME systems ---- Studies reporting on the evaluation of MUME ---- Socio-economical Impact of MUME ---- Philosophical implication of MUME ---- Authorship and legal implications of MUME Submission Format and Requirements ================================= Please make submissions via the EasyChair system at: https://easychair.org/conferences/?conf=mume2019 The workshop is a day and a half event that includes: -Presentations of FULL TECHNICAL PAPERS (8 pages maximum) -Presentations of POSITION PAPERS and WORK-IN-PROGRESS PAPERS (5 pages maximum) -Presentations of DEMONSTRATIONS (3 pages maximum) which present outputs of systems (working live or offline). All papers should be submitted as complete works. Demo systems should be tested and working by the time of submission, rather than be speculative. We encourage audio and video material to accompany and illustrate the papers (especially for demos). We ask that authors arrange for their web hosting of audio and video files, and give URL links to all such files within the text of the submitted paper. Submissions do not have to be anonymized, as we use single-blind reviewing. Each submission will be reviewed by at least three program committee members. Workshop papers will be published as MUME 2019 Proceedings and will be archived with an ISBN number. Please use the updated MuMe paper template to format your paper. Also please feel free to edit the licence entry (at the bottom left of the first page of the new template). We created a new MUME 2019 template based on AAAI template. The MUME 2019 latex and Word template is available at: http://musicalmetacreation.org/buddydrive/file/templates_mume2019/ Submission should be uploaded using MUME 2019 EasyChair portal: https://easychair.org/conferences/?conf=mume2019 For complete details on attendance, submissions and formatting, please visit the workshop website: <http://www.musicalmetacreation.org> http://musicalmetacreation.org Presentation and Multimedia Equipment: ========================================== We will provide a video projection system as well as a stereo audio system for use by presenters at the venue. Additional equipment required for presentations and demonstrations should be supplied by the presenters. Contact the Workshop Chair to discuss any special equipment and setup needs/concerns. Attendance ======================================= It is expected that at least one author of each accepted submission will attend the workshop to present their contribution. We also welcome those who would like to attend the workshop without presenting. Workshop registration will be available through the ICCC 2019 conference system.

On limited resource machines, if you have plenty of RAM, I would suggest running the postgres part of the project in a separate process using something like a python script. Then use OSC for the communication. This way, Pd will never block the audio while the postgres process blocks accessing the db. You can wrap up the project into a script which starts both pd and the python script in the right order. Even better would be to write it in C, but try something like Python first and stick with it if it works well enough. This approach worked quite well for me on my old wearable running a 500 Mhz Pentium 3 with 256 Mb RAM. One thing to do is to balance the process priority toward Pd by using "nice" to make Pd "no nice" and make the python script / postures access program "more nice." I'm a bit conservative and have never approached running *everything* in Pd partially because of this reason. I usually write separate IO programs which then communicate to Pd which does the audio and most of the creative "sauce" / mapping. The added benefit of this approach is that you can easy distribute things if/when you need to, such as expanding an existing installation to have say 10 clients and 1 server. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
