This release includes following fixes: *MyCanvas does not become invisible if it is partially visible in GOP mode *copy-paste from console does not work with the ctrl+c shortcut *Proper focusing out of the selection (where typing into .printout console makes problems for textedfor objects) *Resizing window when text is hidden still prevents resizing below the text size *GOP resize hooks should be visible only if no object is selected *when re-saving prototype abstraction it disappears on the parent canvas *disis_wiimote does not re-detect motion plus every time when re-connecting and re-enabling the extension (partially fixed (needs update to libCwiid, will be updated soon)--for the time being, easiest thing is to enable extension twice; NB: this will not be necessary once the libCwiid is updated) *image and other non-vanilla objects do not translate with the GOP *ggee objects button and image updated, gcanvas disabled as it has too many bugs to be worth fixing (IMO) *implemented gop legacy redraw *selection as part of the infinite undo (for those tricky selections that take a while to do and can be messed up with a single mis-click) NB: ctrl+a is currently ignored, mainly because it is easy to do but will be likely addressed in the next release L2Ork now also supports builds for both 32-bit and 64-bit Linux systems and can be downloaded from the usual place: http://l2ork.music.vt.edu/main/?page_id=56 Bug reports are in high demand, so get busy and let me know of any potential hiccups. -- Ivica Ico Bukvic, D.M.A Composition, Music Technology Director, DISIS Interactive Sound& Intermedia Studio Director, L2Ork Linux Laptop Orchestra Assistant Director, CCTAD Virginia Tech Department of Music Blacksburg, VA 24061-0240 (540) 231-6139 (540) 231-5034 (fax) disis.music.vt.edu l2ork.music.vt.edu ico.bukvic.net

OSC Sequencer IanniX
by chrisgr99 28 Feb '12

28 Feb '12

You may also be interested in a project I started about six months ago, which is a fork of IanniX I call GeoSonix. It will be free and open source. In a week or two it will be available as an alpha download of the source or executables on Bitbucket. At this point only OSX and Windows because I haven't had time to build and test a Linux version. The name GeoSonix comes from a combination of IanniX and GeoMaestro: http://www.zogotounga.net/GM/eGM0.html which is/was based on Keykit, and is my other source of inspiration in the project. Here's an example of what GeoSonix can do: http://vimeo.com/36209199 There are more examples on my Vimeo account. I actually contributed the code for many of the enhancements in the most recent version of IanniX and wrote the updated documentation. However I reluctantly forked it because I wanted to make more of a fresh start than the IanniX team would have wanted (its a long story). I initially focussed on the user interface, making it easier to use, and on bug fixing, making it more robust. Since then I've added lots of other cool features and have more planned. For example: - "projects" are now fully supported and are structured as folders with resource forks like in Ableton Live - there is a patchbay. This allows scores to be easily portable to different system setups, and to be routed to different sound generators - the scripting language now accepts JavaScript commands with normal parameters rather than requiring all commands to be converted to strings. - I've added a harmony processor similar to that in Supercollider - I've extensively refactored it internally, making the code easier to understand and easier to move forward, and fixed lots of bugs. GeoSonix has probably 50 significant enhancements over the most recent version of IanniX. If you're interested, I'll post here again when GeoSonix is available for download. - Chris Graham

[PD-announce] 2nd Pd mini-Con Dublin, Ireland - call for works
by richard duckworth 28 Feb '12

28 Feb '12

Hi all, it gives me great pleasure to announce that the 2nd Pd mini-Con has been given the green light: it will take place in the Dept. of Music, Trinity College Dublin, Ireland on the 11th and 12th of May, 2012. There is wriggle room to spill over to the 10th and/or 13th if needs be. This years 'Con promises to be bigger and better since we have forged mutual alliances with other Irish-based Pd-er camps & circuit-bender groups. There will be a performance night as well in the Music Dept. recital room and break-out room(s) as necessary for workshops etc. This call is for papers, demonstrations, performances, workshops, and /or any Pd-related endeavour. Simply contact me (off-list) with submissions (include your tech spec), or if you have any questions. There is no deadline per se, but if you submit very late, the availability of space/resources etc. might become scarce. Tech specs. etc available on request. All the best, Rich Rich Duckworth Lecturer in Music Technology Department of Music House 5 Trinity College Dublin 2 Ireland Tel 353 1 896 1500 It's the most devastating moment in a young mans life, when he quite reasonably says to himself, "I shall never play The Dane!" ________________________________

pix_openni crash Pd
by Jack 28 Feb '12

28 Feb '12

Hello, i compiled pix_openni for my Ubuntu 11.04 with Gem 0.93 and Pd 0.42.6. When i open the patch 'pix_openni-help.pd', i get in the Pd console : [pix_openni]: pix_openni 0.03 - experimental - 2011/2012 by Matthias Kronlachner [pix_openni]: using multiple kinects not available now... chosen ID: 0 [pix_openni]: OPEN NI initialised successfully. And [pix_openni] object seems to be OK. But when i create the Gemwin, Pd crash : Erreur de segmentation jack@jack-N55SF:~$ socket receive error: Connection reset by peer (104) I did something bad ? ++ Jack

[PD-announce] pdlua and tclpd: now embedded in Pd-extended 0.43
by Hans-Christoph Steiner 28 Feb '12

28 Feb '12

There are two new, easy ways to write objects for Pd: tclpd by Federico Ferri and pdlua by Claude Heiland-Allen, Frank Barknecht and Martin Peach. Both are now included in Pd-extended 0.43 and are automatically loaded at startup. That means you can write a script in Lua or Tcl and have that script be a true object in Pd. Both pdlua and tclpd provide the large majority of the Pd externals API, and you can even write GUI objects using tclpd. Tcl and Lua both excel at handling strings, one thing that Pd is not the best at, so if you have a project that needs to parse or manage a lot of strings, then you have a new approach. There are some other ways of using other languages to write objects for Pd: pyext for Python and pdj for Java. These two are different in a key way than pdlua and tclpd. pyext and pdj allow you to load scripts into an object called [pyext] or [pdj]. tclpd and pdlua let you create full Pd objects that are completely transparent to the user. You create an object written in tclpd or pdlua just like any other Pd object, and those objects can have their own help patch too. Both pdlua and tclpd come with a lot of examples, go to the Help Browser and find them in the list of libraries there. I also started writing the 'tclfile' library to bring the Tcl file API to Pd: http://puredata.info/downloads/tclfile .hc _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

0.43 oddities (Was Re: pdlua and tclpd: now embedded in Pd-extended 0.43)
by András Murányi 28 Feb '12

28 Feb '12

Just a list of strange things I noticed running latest autobuild - on this account where Pd was never used before. (some of these are perhaps known or perfectly ok. Now that pd on my account is practically out of order, I'm kind of a newbie when I start it up...) - starts up with message: Cannot read GUI prefs file: "~/.config/pd-extended/recentfiles.conf" - "maximum object loading depth 1000 reached" message when object not found - there is no .pdextended file. If I'm not wrong, it's created when you first try to save preferences, but your preferences won't be saved. - Before exit, if chose to save dirty new patch, an Application Error window appears: > Not connected to 'pd' process > Not connected to 'pd' process > while executing > "error "Not connected to 'pd' process"" > (procedure "pdsend" line 6) > invoked from within > "pdsend "pd watchdog"" > (procedure "pdtk_watchdog" line 2) > invoked from within > "pdtk_watchdog" > ("after" script) > - After quit i get this error every time: pdsend errorname: >>error writing "sock6": broken pipe<< - Default .pdextended has no 'path' list - When using 'path' in .pdextended, many, seemingly pointless (?) errors come up like this: > WARNING: duplicate 'manual' library found! > '/usr/lib/pd-extended/extra/cyclone/manual' is active > '/usr/lib/pd-extended/extra/iemlib/manual' is duplicate > or like this kind: > WARNING: duplicate 'pdlua' library found! > '/usr/lib/pd-extended/startup/pdlua' is active > '/usr/lib/pd-extended/extra/pdlua' is duplicate > or like this: > WARNING: duplicate 'oscx' library found! > '/usr/lib/pd-extended/extra/oscx' is active > '/usr/lib/pd-extended/extra/oscx' is duplicate > András
