PCD8544 (Nokia 3110 and 5110 84×48 LCD) on Raspberry Pi
by Julian Brooks 25 Apr '13

25 Apr '13

Hi all, Bit of an initial punt here: Before I dive into experimenting with the above lcd display does anyone have any experience with these and had it working with Pd? I've bought a rather nice readymade board for use with the RPi http://www.raspberrypi.org/phpBB3/viewtopic.php?f=59&t=38204 and have the test python script working but currently that's about it. Spent several hours reading around the subject and weirdly python makes my brain hurt but C I'm very curious about and interested in (probably my latent thinking that 'proper' Pd'ers can handle a bit of C) but to engage directly with it in Pd somehow would be bloody marvellous. Although I've bought it for the Pi there seems to be lots of people hooking them up to an arduino so that made me think that maybe someone's already been here/done that. As per usual; any and all pointers gratefully accepted. Best wishes to all, Julian

mean power frequency of a non-audio signal
by Marco Donnarumma 24 Apr '13

24 Apr '13

Hey folks, how would you go about computing the mean power frequency of a non-audio signal? I'm aware of the different libraries available for audio signal feature extraction, but can't find much info about non-audio signals. thanks! -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.

[ANN] RPi osc video player
by Antoine Villeret 24 Apr '13

24 Apr '13

hi all, i've just start an OSC video player on the RPi for now, it's just an embryo, it plays a demo video file defined in the code, it's a proof of concept : it can work but it needs some work for now the only feature implemented is the 4 corners perspective correction (intended to be used with a video projector) and i made a small pd patch to control the player when i'll have opportunity, i will add thoses features : - OSC message to choose video file - OSC transport control (play, pause, speed, loop...) - OSC message to choose shader file and control its parameters - command line arguments to choose video file, OSC port, and parameters it's based on the hello_video_cube example from Raspbian, so it uses the hardware decoding capabilities of the Pi of course, it's open source, feel free to test it : https://github.com/avilleret/rpi_osc_video_player + a -- do it yourself http://antoine.villeret.free.fr

Negative input numbers for [pow] return 0
by Joe White 24 Apr '13

24 Apr '13

Hi, Just realised putting a negative number into the [pow] object outputs '0'?!? For example if I do: [-1 ( | [pow 2] it returns 0, where I would expect it to return 1. Is this a known limitation or bug? Are there any work arounds if I want a variable power? (I'm running Pd 0.44.1 on OS X Mountain Lion) Thanks, Joe

Missing objects in Pd-Extended Intel OSX?
by Martin Dupras 23 Apr '13

23 Apr '13

I'm running 0.43.3-extended on a MacBook Pro Retina (Intel Core i7), with OSX 10.8.3. I've only noticed in the last couple of days that some objects are not loading. For instance, if I bring up the netserver-help.pd help file, the netclient object loads, but netserver doesn't. I also notice that some objects in iemmatrix do not load. For instance mtx_mul loads, but not mtx_mul~. Confusingly, the mtx_+ object in mtx+mul-help.pd doesn't load, but it does if I open mtx_add-help.pd. I'm very confused. Can anyone enlighten me? (For the record: I've deleted my .plist file and replaced the Pd-extended app with another fresh copy. No difference.) Many thanks, - martin

[PD-announce] A permanent technician job at the university of Huddersfield
by Julian Brooks 22 Apr '13

22 Apr '13

Hi, P.A. Tremblay has asked me to pass this on (Pd-E is on all of our music computers these days btw): Dear all Sorry for the cross-posting, as I want to spread the word! I think this might interest the most technically inclined, in search for a permanent post. It is not an academic job, but we definitely need some help on maintaining our studios's standard, and speciality, knowledge and wisdom in the virtual studio implementation and maintenance would be welcome! http://www.hud.ac.uk/hr/jobs/jobdetail/index.php?jobId=1863 pa _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Lowpass to Highpass morph
by Jeppi Jeppi 22 Apr '13

22 Apr '13

Hi again, I am looking for a suitable filter or combination of filters such that with a single control the user can morph somehow between very lowpass-lowpass-flat-highpass-very highpass response... What pd filters would you find suitable for that?

flext install (for another amateur)
by Chris Jack 20 Apr '13

20 Apr '13

Hey folks, I have been trying in vain to install flext (cvs download) on my 10.6.8 snow leopard Mac. I've tried it every which way - both using the buildsys and autoconfig - and just cannot get the bugger to build. I have refreshed before each try with a new copy of flext via cvs. Using autoconfig I seem to get this error during build: flutil.cpp: In static member function ‘static void flext_single::CopyMem(void*, const void*, int)’: flutil.cpp:33: error: ‘BlockMoveData’ was not declared in this scope flutil.cpp: In static member function ‘static void flext_single::ZeroMem(void*, int)’: flutil.cpp:44: error: ‘BlockZero’ was not declared in this scope make[1]: *** [libflext_pd_s_a-flutil.o] Error 1 make: *** [install-recursive] Error 1 And using buildsys these errors: Chris-Jacks-Computer-2:flext chrisjack$ bash build.sh pd gcc make -f ./buildsys/gnumake-sub.mak PLATFORM=mac RTSYS=pd COMPILER=gcc BUILDPATH=./buildsys/ PKGINFO=package.txt BUILDCLASS=flext USRCONFIG=config.txt USRMAKE=build/gnumake-mac-gcc.inc TARGETMODE=release TARGETTYPE=single _build_ buildsys/mac/gnumake-gcc-targets.inc:22: warning: overriding commands for target `pd-darwin/release-single' buildsys/mac/gnumake-gcc-targets.inc:18: warning: ignoring old commands for target `pd-darwin/release-single' mkdir -p pd-darwin/release-single mkdir -p pd-darwin/release-single/ g++ -c -DNDEBUG -DFLEXT_EXPORTS -DFLEXT_SYS=2 -DPD -I/Applications/Pd-extended.app/Contents/Resources//src source/flext.h -o pd-darwin/release-single/flext.h.gch touch source/flbase.cpp mkdir -p ./ g++ -c -ffast-math -Os -ftree-vectorize -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -mmmx -msse -msse2 -msse3 -mtune=prescott -DNDEBUG -DFLEXT_EXPORTS -DFLEXT_SYS=2 -DPD -I pd-darwin/release-single -I/Applications/Pd-extended.app/Contents/Resources//src source/flbase.cpp -o pd-darwin/release-single/flbase.opp_i386 source/flbase.cpp:29:22: error: g_canvas.h: No such file or directory source/flbase.cpp: In static member function ‘static bool flext_obj_single::GetParamSym(t_atom&, const t_symbol*, _glist*)’: source/flbase.cpp:130: error: ‘canvas_realizedollar’ was not declared in this scope source/flbase.cpp:133: error: ‘canvas_realizedollar’ was not declared in this scope make[1]: *** [pd-darwin/release-single/flbase.opp_i386] Error 1 make: *** [build-release-single] Error 2 I am pointing the variables in the txt files to the correct locations, of that I am sure. I have also begun with a fresh install of Pd-extended 0.43.4 - could this be it? Too new-a-build? Need I use Pd vanilla to get flext to play ball? I'd really rather not as I already have a bunch of stuff invested in Pd-extended and I want to avoid having to compile countless externals just to run the same projects in vanilla (though this would be a very long-winded option). Your helpings are highly appreciated. Cheers, CJ. -- Chris Jack *art/research* http://itsmrjack.com/ *discus jockeying/sound art* http://soundcloud.com/itsmrjack/
