Two-dimensional gesture mapping for interactive real-time electronic music instruments
by Thomas Grill 11 Jul '09

11 Jul '09

Hey all, in case someone is interested here's my recently finished master thesis: http://grrrr.org/pub/grill-2008-master-2d_gesture_mapping.pdf or in very compact form, as a presentation poster: http://grrrr.org/pub/grill-2008-master-poster.pdf This thesis describes a novel, fairly general and (for the player) non-technical interface concept for software-based music instruments. The actual proof-of-concept instrument has been realized using pd and gem (with a number of optimized flext-based external objects to make it all possible on current hardware). gr~~~

jack_transport improvements
by Jacob Lee 28 May '09

28 May '09

I've added some code to the jack_transport external (tb/jack_transport/ in pd-extended) to show the current bar/beat (and also bpm and tempo) in real time. Messages are only sent out when pd is computing audio, and also no more than once per beat (to avoid floods of messages). I'm not outputting all the available information from the jack transport -- e.g. the current tick within the beat -- either because it updates too quickly or because it's just not useful to me, but it would be trivial to add those. The motivation here is that I'm using klick -- http://das.nasophon.de/klick/ -- as the jack transport master (mainly to control sooperlooper), and now it is possible to trigger events within pd at particular beats or bar numbers. The code is available at http://artdent.homelinux.net/svn/jack_transport~/ . The makefile should be suitable for building jack_transport~ from inside a directory that is sibling to the existing jack_transport. I've only tested it on Linux, but it should work anywhere jack_transport does. I hope this external is useful to others. Suggestions for improvements are of course welcome. -- Jacob Lee artdent(a)gmail.com

gcanvas?
by Oded Ben-Tal 23 May '09

23 May '09

gcanvas is behaving differently in these two situations: linux (fc10) pd-0.39 object is gray and can resize correctly win pd-extended 0.40.3 object is white and resize changes the input area but not the object. Is it a feature or a bug? In both cases the values seems to be done correctly. Oded ___________________________________________________ Oded Ben-Tal http://ccrma.stanford.edu/~oded

[import]ing libdirs from places other than extra/?
by Luke Iannini 24 Mar '09

24 Mar '09

Hi hans/all, I'm trying to switch my entire library of patches over to [import] and removing everything from my path to decrease loading time of my very nested patches. Everything worked great for the libdirs in extra (in the Pd-extended.app bundle), but I'm not having any luck [import]ing from anywhere else (i.e. my personal patch collection). According to http://puredata.info/docs/faq/how-do-i-install-externals-and-help-files-wit… , I was under the impression I could add libdirs (which I have added -meta.pd files to) to ~/Library/Pd or /Library/Pd and [import] would find them. But, I'm unable to instantiate any of the patches in my libdirs after doing this and [import]ing them. [import] does not, at least, complain, when I instantiate it (i.e. I get "libdir_loader: added 'Concepts' to the canvas-local objectclass path" rather than "error: [import]: ERROR: can't load library in 'Concepttt'") so, something is working. Moving my directories into extra/ fixes the problem, but I'd rather not do that! Also, is it defined at a source level that ~/Library/Pd and /Library/Pd are the only places libdirs can be loaded from (I couldn't find it i so)? Or, is is just that every folder in the global path is searched for libdirs (or, at least, is that how it's meant to be)? Cheers Luke

most stable/efficient way/object to play large video files?
by Martin . 18 Mar '09

18 Mar '09

Hi all, I need to play some video files (~700mb) in a theatre setting, which demands stability. Till now ive used pix_film, but there has been some crashes at seemingly random times when loading the files. Im wondering if there are any precautions or desired objects to use (pix_film, pix_movie, pdp, ...) that are more more stable? Also, is any object more efficient for dealing with larger files? cheers, Martin

Hi, I started to learn to use Blender for controlling it with puredata with OSC protocol, I would have been glad to use gamelogic sockets instead but it's poorly documented and OSC seems more useful in huge project implementations Welcome to any kind of comment instructions are into blend file
