Sometimes all data-structures are redrawn
by Roman Haefeli 25 Mar '23

25 Mar '23

Hey all Sometimes when I load certain patches containing data structures, all data structures in all patches of an instance of Pd are redrawn. This is barely noticeable with one single patch, but if many patches are loaded with each using many scalars, the whole redrawing process becomes unbearable. In larger netpd sessions, the process can take a few dozen seconds, depending on number of loaded instruments and probably other factors (maybe CPU speed, but none of the cores is fully loaded during the redrawing process). During the process, GUI elements like slider handles or number boxes are not updated and all DS based GUIs are not usable either. [cnv] labels are not affected (why?). The redrawing seems to cause drop outs in DSP processing. I got reports that glitches are more pronounced on Windows (or on slower computers?). I tried to figure out what exact conditions trigger such a redraw in the hope that they can be avoided. I found that the order objects of a data structure template are created matters. If [drawsymbol] was created before [struct], loading such a patch triggers the redraw. After changing the creation order, loading the patch doesn't trigger the redraw. This video illustrates it: https://netpd.org/~roman/tmp/ds-redrawing-everything.webm Apparently, there are other conditions that trigger a redraw. I tried to make sure that all [struct] objects are created last in one of my patches, but loading the patch still triggers the redraw. What are the conditions that lead to a redraw? Why are all data structures redrawn and not only the ones using scalars from the changed template? If order matters, why aren't the patches saved with the correct order? Why is the process so slow if it is apparently not CPU- bound? Is it because of the "chattiness" between GUI and core? Here another video showing how redrawing affects iemguis: https://netpd.org/~roman/tmp/ds-redrawing-affects-iemguis.webm Roman

[PD-announce] artnetlib v0.1.0 released
by Lucas Cordiviola 22 Mar '23

22 Mar '23

hi list, releasing artnetlib: ---------readme----------- turn your Pd patch into an Art-Net controller. Art-Net is an Ethernet protocol based on the TCP/IP protocol suite. Its purpose is to allow transfer of large amounts of DMX512 data over a wide area using standard networking technology. https://en.wikipedia.org/wiki/Art-Net https://www.artisticlicence.com/WebSiteMaster/User%20Guides/art-net.pdf artnetlib is a Pd library with 5 objects: - [artnetfromarray] - polls a Pd array and convert the values to a list of DMX 1 byte ints - [artnetsend] - format a Pd list of ints with an _ArtDMX_ header where you specify "physical" and "universe". - [artnetudp] - send the _ArtDMX_ package to a specified ip - sends _ArtPoll_ and receive _ArtPollReply_ (used to discover the presence of other Controllers, Nodes and Media Servers.) - receive data from other Art-Net compatible devices - [artnetroute] - routes received _ArtDMX_ packages according to its "physical" and "universe". - [artnettoarray] - convert _ArtDMX_ packages to a Pd list. -------------------- repository: https://github.com/Lucarda/pd-artnetlib bug reports: https://github.com/Lucarda/pd-artnetlib/issues happy lighting!!! :) Lucarda -- Mensaje telepatico asistido por maquinas. _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

A web frontend for Pd
by Giulio Moro 19 Mar '23

19 Mar '23

Here's something the Chair and Bela teams have been working on for a few months: a proof-of-concept web interface to Pd. https://github.com/BelaPlatform/pure-data-web-GUI This leverages the refactored communication protocol effort by Iohannes in order to obtain a "toolkit-agnostic Core<->GUI Communication" (https://github.com/pure-data/pure-data/discussions/1695), which resulted in https://github.com/pure-data/pure-data/pull/1765 . This is part of a broader project outlined in https://github.com/pure-data/pure-data/pull/1693 . Now, this pure-data-web-GUI repo comprises three components: - pd: is started with -guiport so that it doesn't start its own GUI - the "shim": a very thin layer of websocket that forwards messages to/from Pd and the browser - the "frontend": the actual HTML5 stuff, written using the svelte framework. For now, you can try it out with docker following the instructions included in the repo. The easiest way is to run it with the Pd it comes with (which is run inside docker and thus doesn't have audio/MIDI I/O capabilities), but you can easily connect it to your own Pd server instance (assuming it comes from this branch https://github.com/giuliomoro/pure-data-1/). The docker containers are used to simplify the development effort, but ultimately this can be packaged up in a self-contained app (even for Android, if required), or you can have it run embedded (e.g.: on a Bela board) while displaying the GUI in a web browser (which is actually our primary goal). It is by no mean complete or perfect, but I hope it shows that there is a tcl-tk-compatible, non-tcl-tk future possible for Pd. As it is, it even allows (well, with a lot of effort on the user side, but very little effort was put into it from the dev side) to patch on a touchscreen. You may be wondering how this differs from the purr-data web GUI. Good question. This is a complete rewrite and it aims to use "stock" Pd as a backend server, by means of a communication protocol that has been refactored (by Iohannes) such that Pd no longer sends out raw tk messages, but rather tcl-compatible commands that are higher level and also easier to parse in other languages (the parser here is written in js). So right now you can run the same Pd binary (from this branch) deciding at runtime if using a tcl GUI or a web GUI. Nifty. The aim is eventually to upstream this communication protocol into vanilla, to make it easier to swap GUI frontends. Hopefully this can eventually help other forks with custom GUIs such as PlugData so that they don't have to maintain their own fork of Pd. Best, Giulio

[PD-announce] New Master in Composition with Focus on AI - HfM Trossingen
by Luc Döbereiner 16 Mar '23

16 Mar '23

New Master in Composition with Focus on AI - HfM Trossingen Application period March 1 - April 1, 2023 Starting in October 2023, the University of Music (HfM) Trossingen (Germany) will offer a master's degree program that is unique in Europe and aims to train a new generation of artistically and technically competent composers, sound artists, and music designers, especially by critically exploring the creative possibilities of AI-based technologies. This program (Master of Music in Composition) builds on the music technology teaching foundations of the HfM Trossingen and takes place in close cooperation with Furtwangen University. The students are taught by an internationally renowned team of researchers and experienced artistic practitioners, first and foremost Prof. Dr. Luc Döbereiner and Prof. Dr. Joachim Goßmann. In addition, this course is being developed within the framework of a cross-university project funded by the BMBF (KISS - Artificial Intelligence Service and Systems), whose long-term goal is to establish a center of excellence for the sustainable development of AI. As part of the master's program, interested students with prior musical and/or technical experience at the bachelor's level can choose one of three concentrations: Music Design, Instrumental Composition, or Electroacoustic Composition. Available modules of study range from Digital Lutherie, Experimental Sound Synthesis, and Interface Design to Sound Ecology and Digital Ethics. In addition, a new space for the conception, experimentation and realisation of artistic projects ("Latent Space" - Space for Artistic Research and Design in Music and AI) is being created. The entrance examination consists of two phases. In the first phase, in addition to the general application documents, the following documents must be submitted (via Post, USB-stick with max. file-size of 1 GB): Motivation letter (max. 1 page) Curriculum vitae including chronological overview of musical/artistic development Media documentation of own works with explanation (min. 2 pages) Exposé - description of the planned artistic project (max. 3 pages) After reviewing the documents, the examination committee selects candidates for an in-person examination in Trossingen. This second phase consists of an interview about the submitted work and the exposé (approx. 30 min). Further information about the program, application requirements can be found on the following page: https://www.hfm-trossingen.de/ai-in-music contact: l.doebereiner(a)doz.hfm-trossingen.de _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Thanks for confirmation that this does indeed work.
