Re: [PD] My personal GEM preview inside a patch...
hello, thanks for the patch, unfortunately, i think it's still too slow to be usable. better than deleting everything and creating them back with new colour, i tried to change colours of the existing one. i tried with both the canvas version and the data structure version. in both case, things are lot's faster in the original patch than in my optimized version. that's not what i was expecting. how come that it's faster to delete a canvas and create a new one than changing a canvas colour?

Re: [PD] My personal GEM preview inside a patch...

In my experience the faster solution for an in patch preview solution was pix_preview or using gridflow and convert gem pix to gridflow list. Actuallly this was the method I used most in my workshops until an installer package of gridflow was available.

The only downside is if you yank the USB soundcard while jack is running pd waits on jack to report that it lost the soundcard and stops which can take up to 20 seconds. In other words in this case it's jack that is hanging and consequently making pd hang as well but only temporarily.

Re: [PD] My personal GEM preview inside a patch...
hello, well, having 2 pd instance will create more problem that it will solve in this situation. - pix_data will appear to use less cpu, but pix_data did not use cpu, it use bandwidth between cpu and gpu. and this can't be share between cpu. - the main bottleneck of this object is the rendering part. not really getting the data. so the pd~ / sharemem will not help. one possible optimisation is using pix_resize/pix_dump to output all data as a list that can be put on a table. pix_data will make as many call as pixel, but the pix_dump will make only 1 call to the gpu. it look like it work a bit better, but i did not really benchmark it. (since that's not where the bottleneck is) i'm however disappointed that destroying / creating a new object is faster than changing an object colour. cheers c Le 25/06/2013 11:16, Philippe Boisnard a écrit : Hello To continue this question, perhaps, this preview can be create between 2 instances of puredata, with sharemem to transmit data colours.

Re: [PD] Where is vanilla's makefile and other stuff located?
Hello Alexandros, The standard installation path for Pd in Ubuntu is /usr/local/lib/ (except for the binary file /usr/bin). Afaik the makefile doesn't install itself somewhere. If you don't know navigate to your pd-source. If you don't seem to have them already type ./autogen.sh and a configure script and a makefile will be created. To be sure no vanilla is installed type sudo make uninstall, then make make install to (re-)install pd. That should be it. --Funs On Tue, Jun 25, 2013 at 10:22 PM, Alexandros Drymonitis adr...@gmail.comwrote: Btw, there must be something wrong cause Pd doesn't have an icon. When I Ctl+Tab to change between applications, in Pd's icon place there's a question mark.. And another minor thing, when Pd opens I get this in the Terminal: 'was... 1' (then Pd opens, no problem) and this error in the Pd window: WARNING: Font family 'Courier' not found, using default (DejaVu Sans Mono) Are there any stuff lost?

I think I've created some mess as there are symbolic links pointing at other symbolic links pointing at pd-extended. Even though I thought I hadn't managed to install vanilla, I realised it's sitting in /usr/bin/ as puredata. In /usr/lib/ there is a pd/ directory which includes a doc/ and a extra/ directory, but these two directories have only Gem stuff, no [bonk~] or [fiddle~] or [expr~] (even though I can create all these objects). I have a vanilla version is OS X and in /Applications/Pd-0.44-0 there is the Contents/ directory where all the necessary stuff lies (Resources/extra etc.). Anyone knows where all this stuff is sitting in Ubuntu?

[PD] specify number of alsa midi out ports
Hello again, Is there a way to specify the number of ALSA MIDI Out ports (in Linux) via the command line or using a command from within Pd? I can specify this running pd-extended -alsamidi and selecting via the GUI: Media--Midi Settings... - but need to specify the number automatically.

The following will do it: On Fri, Feb 3, 2012 at 7:58 AM, Max abonneme...@revolwear.com wrote: if you want to simply reconfigure the audio/midi settings programmatically it might be revealing to listen to the internal pd messages [receive pd] | [print] and then change the audio/midi settings. you can use those messages which will be printed in the console to change your settings when sending messages to a [send pd] that's the principle applied by the mediasettings library hans mentioned.
