helpbrowser and the paths
by IOhannes m zmoelnig 05 Sep '11

05 Sep '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 while preparing a debian package of Gem, i stumbled across a help-browser weirdness, which i'm not sure how to fix. the background: Gem comes both as a big binary (Gem.pd_linux) and a number of abstractions. everything is installed into /u/l/p/extra/Gem (to avoid cluttering the global filespace with Gem files); in order to use the abstractions painlessly (that is: without prefixing them "Gem/"), the /u/l/p/extra/Gem path has to be added somehow to Pd's search paths. (this can be done manually via the -path, or automatically by Gem). so far so good. the problem: starting Pd with Gem added to the paths, results in a not-so-nice help-browser experience: basically the left column (the one that is crucial for navigating the various directories) is filled with 224 or so help-patches from Gem, sorted alphabetically (so directories are lost somewhere between files), and upper-case before lower-case. of course there is also a directory entry for Gem/ in the help-browser, making the information accessible two times (adding more confusion) given that both GF and Gem are to add their paths automatically on startup, the left column if the help-browser might have >500 help-patches and several dozens of directories. i don't know exactly where to fix the problem, but a simple solution would be to only allow directories on the left side (and add an entry for "<searchpaths>" (probably an entry for "all searchpaths" and separate entries for each searchpath), rather than throwing everything together. fgmasdr IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk2/wrQACgkQkX2Xpv6ydvT6UACghrBixWNveMT8bMl9u/Vdu+l3 f80An2WzIBvBwaeDNHA3vua4Hj3npyN1 =yl89 -----END PGP SIGNATURE-----

Re: [PD] reverb in pd

+1 on ben saylor's partconv~ - works excellently. arm yourself with the free acousticas IR's... http://www.acousticas.net/World/IRs/AcousticasM7.zip of the $3,500 bricasti m7 unit... http://www.bricasti.com/m7.html ...and you'll not go back to algorithmic reverbs again. or just get some balloons and record your own! (grab those IR's soon as it seems acousticas have gone out of business. took me a few attempts to check but the link is working.)

Dynamic patching with audio - review
by Jérôme Abel 19 Aug '11

19 Aug '11

Hi dynamic community, I'm working on an open source multiuser game with a sound experimentation focus. The choosen sound engine is our favorite one Pure Data. Let's imagine populate a 3D world with pd sound patchs ! The issue is to create/destroy audio abstractions (made by users/artists) and connect/disconnect them. The audio path system must be compliant with paths in a 3D world. A sound pass through rooms and apertures : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/pathfind… It must be dynamic like a game. I was enjoying doing this with pd, but ... my hair become more and more white. It's quite difficult. I propose here to write a little review of this issue. To be completed, to be rectified. Don't forget that the best is the easiest way (less compilation, less dependancies, less bad tricks, etc.) and cross-platform (Linux/MacOSX/Win). ****************************** *** DYNAMIC PATCHING TESTS *** ****************************** All my tests and comments here (patchs, screenshots) : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching.tar.gz 1 - PURE DATA -------------- First, considering audio in Pd, we can read "do not use dynamic patching" !! http://puredata.info/docs/tutorials/TipsAndTricks#how-to-avoid-audio-drop-o… It's not very encouraging. So what ? Which tool use then ? A comparison of audio tools : http://en.wikipedia.org/wiki/Comparison_of_audio_synthesis_environments 2 - SUPERCOLLIDER ----------------- Supercollider seems to work well with dynamic audio connections. We can read "Adding an Effect Dynamically" and so on. http://danielnouri.org/docs/SuperColliderHelp/Tutorials/Tutorial.html "It is an efficient and expressive dynamic programming language" http://en.wikipedia.org/wiki/SuperCollider So, how interface it with a pd patch ? I know that it's ok with OSC messages, but could we imagine, Supercollider as a the connection manager and Pd as the sounds loader ? An audio communication between Supecollider and Pd. 3 - PYTHON ---------- Some projects use Python to make dynamic patching. I don't know if those projects are really working with full functionnalities like a complete audio path system. I think the most advanced is Purity but may be not enough, see the roadmap. Any feedbacks in use ? Purity is a Python library for Pure Data dynamic patching. http://wiki.dataflow.ws/Purity Pyata - a Library that allows you to use Pure Data inside Python svn checkout http://pyata.googlecode.com/svn/trunk/ pyata-read-only Automata-topd is a small collection of Python classes to communicate with Pure Data sending FUDI messages by socket. https://github.com/automata/topd PuréeData is a browser-based PureData interface for a remote, central server that allows live, collaborative patching for anyone, anywhere. https://github.com/virgildisgr4ce/PureeData 4 - PURE DATA - LIBPD --------------------- Let's come back with Pd. We know that Pd was used in a game Spore : http://lists.puredata.info/pipermail/pd-list/2007-11/056212.html It could be a solution to handle dynamic audio patching. Any feedbacks ? Libpd turns Pd into an embeddable library, so you can use Pd as a sound engine in mobile phone apps, games, web pages, and art projects http://puredata.info/community/projects/software/libpd/ How to use Pure Data as an API http://jeraman.wordpress.com/2009/03/22/how-to-use-pure-data-as-a-api/ 5 - PURE DATA - DYN~ -------------------- This external allows the dynamic creation and deletion, connection and disconnection of standard Pd objects and abstractions. But : dyn~ is bound to the PD version it is compiled for. http://puredata.info/Members/thomas/dynext I success compile it. It seems a good system. If we compile a binary for 3 or more plateforms, will it work just with the binaries ? We must see advantages with my system (pd-messages + index + abstractions) http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/dyn-audi… 6 - PURE DATA - IEMGUTS ----------------------- We know reflection in Pd with iemguts. I'm not comfortable with it. Any feedbacks about the issue ? https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/externals/iem… http://lac.linuxaudio.org/2009/cdm/Saturday/18_Zmoelnig/zmoelnig_pdreflecti… 7 - PURE DATA - PD MESSAGES --------------------------- A review with pd internal messsages. http://puredata.info/Members/eni/techniques In Pd : /usr/lib/pd-extended/doc/Pure Data/manuals/pd-msg Basic tests : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/dyn-audi… 8 - PURE DATA - MATRIX~ ----------------------- 'iemmatrix' provides a suite of matrix processing and linear algebra functionality. http://puredata.info/community/projects/software/iemmatrix The problem here, the numbers of rows and columns are fixed. 9 - PURE DATA - COORDS / WIRELESS --------------------------------- System with receive~/throw~ and catch~/send~ (many-to-many connections) : http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/dyn-audi… http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/dyn-audi… Do you think receive~/send~ could be use in a dynamic audio patching ? Is there a problem with buffer or something like that ? Any feedbacks with a lot of connections ? 10 - PURE DATA - CREATE AUDIO ABSTRACTIONS ------------------------------------------ There is a problem when I create an audio abstraction. The sound of the abstraction is not working while other previous audio objects are working. We have to send a mouseup and cut message to simulate mouse activity ! http://abel.jerome.free.fr/newatlantis/AudioDynamicPatching/images/dyn-audi… *********************** *** OTHER RESOURCES *** *********************** DYNAMIC PATCHING ---------------- http://jeraman.wordpress.com/tag/dynamic-patching/ PURE DATA MAILING LIST ---------------------- [PD] dynamically settable many-to-many cordless audio routing http://www.mail-archive.com/pd-list@iem.at/msg29163.html [PD] About dynamic patches http://lists.puredata.info/pipermail/pd-list/2002-05/006646.html [PD] [PD-announce] many - a library for managing many instances http://lists.puredata.info/pipermail/pd-list/2010-11/084446.html http://puredata.info/community/projects/software/many [PD] About dynamic patches http://lists.puredata.info/pipermail/pd-list/2002-05/006658.html [PD] Automated object/message/etc creation http://lists.puredata.info/pipermail/pd-list/2005-11/032911.html DYN~ ---- http://konkanok.com/2010/12/dyn-object-for-pure-data/ DYN~ - INSTALLATION ------------------- --- flext --- - Download flext, see readme.txt, see build.txt - bash build.sh pd gcc - edit buildsys/config-lnx-pd-gcc.txt : # where is the PD source package?

[PD-announce] The RjDj (and Pd) Reactive Music Forum is there!
by Frank Barknecht 18 Aug '11

18 Aug '11

Join us at the RjDj Reactive Music Forum: ========================================= http://more.rjdj.me/forum/ After more than a year, RjDj has developed into one of the most loved music applications on iPod/iPhone. Literally thousands of music lovers spend hours listening to reactive, algorithmic, generative new music generated in realtime on their little mobile computers. Even musicians like Carl Craig dive into the RjDj world by now. The music of RjDj is composed with Pure Data as the RjDj composition software. It's pretty cool to know that Pd patches are enjoyed by people around the world in Europe, the States, Japan, wherever. We @ Reality Jockey felt like it would be beneficial to create a place where the experience and creation of reactive music could be discussed, both in relation to RjDj and beyond - so we have created a reactive music forum for just that. So there it is: We're pleased to announce the opening of the "RjDj Reactive Music Forum": http://more.rjdj.me/forum/ New Scenes available ==================== In not totally unrelated news we also have many new Scenes available on rjdj.me, most of them free as in beer or even speech. There is stuff from Japan: http://more.rjdj.me/2009/11/03/new-scenes-from-japan/ where RjDj is becoming big as Natto, or half a dozen new Scenes by Pd experts like Martin Brinkmann: http://more.rjdj.me/2009/10/15/half-a-dozen-new-scenes/ All this is Pd vanilla btw. :) And of course your music could be a part of the reactive music experience as well. Just read http://more.rjdj.me/composer/ to see what changes you may have to make to your existing Pd patch to tranform it into a scene for RjDj - and then how to upload it to rjdj.me. Maybe your scene will be the next big thing?

GEM: borderless window is also always on top (and hasn't an icon)
by Matteo Sisti Sette 01 Aug '11

01 Aug '11

Hi, In ubuntu, if I send "border 0" to [gemwin], then the window (once created), besides being borderless which is the expected part, also sticks on top and doesn't have a button in the panel on the bottom of the screen as windows usually have. Not so in Windows, where it just creates a borderless window which, a part being borderless, behaves as any other window. Is there a way in Linux to get a gem window that is simply borderless without sticking on top and without having to renounce to the panel button?? thanks m.

Waiting an array to be finished reading
by Arda Eden 06 Jul '11

06 Jul '11

Hi all, I'm reading a drum loop from an array. While playing when i read another loop in to the array it naturaly keeps playing from the phasor's current value. How can i wait the array to be finished reading before writing the new sound file into the array ? Thanks.

rockafella time-stretcher
by Patrice Colet 26 Jun '11

26 Jun '11

I've turned the B14.rockafella audio example into an abstraction where [phasor~] has been replaced by a [line~] for triggering the sample reading, the abstraction and a test patch is attached. Once the soundfile has been loaded into a table we just need to set the original tempo of the soundfile, and the tempo at which we want the soundfile to be played. If we want the soundfile to be played in loop mode, we just have to trig again when the sample reading is over, by using [del] for example, or [qlist]. The stretch works good but something very strange is happening, let me try to explain, when the read point reaches the middle of the soundfile a noise is appearing, and I couldn't determine why, it sounds like a buffer overflow, or a little distortion. this is happening when both tempo have the same amount. Maybe the method for reading a soundfile is different when using [line~]? I wouldn't like to use the vocoder method because it takes a lot of cpu and artifacts comes whenever the sound is stretched or not. -- Patrice Colet

control lot of audios files with arduino + puredata
by FernandoG 23 Jun '11

23 Jun '11

Hi i need to design a sistem to control 40 diferents audio files and playback in a stereo sistem. I was thinking to use puredata and arduino, load the 40 audios in a pd patch and use 40 switches and resistors into some arduino inputs to trigger and playback any of the 40 audios in pd. Every switch will be conected to a diferent resistor to generate diferents voltages then arduino inputs can diferenciate witch audio to playback. Also i need to power on a led any time a specific audio is been playback. The 40 audios will not be playback simultanusly, but probably al least 15 or 20 could be. Anybody knows about a similar proyect? can i use analog input to control various samples or its not good idea? multiplexors? do i need to use an arduino mega or its not necesary?can i power 15-20 led simultaneously? the best way to do this system stable for long long time? Thanks
