another day's raspberry pi experiences
by geoffroy 16 Sep '12

16 Sep '12

HI there, I am trying to follow how to compile pd on the raspberry pi and I am stuck at the ./configure in the src folder. The git downloaded all the files and everything seems fine up to that point but there is no configure file in the src folder, so I get a no such file or folder when I do the ./configure. I try the ./autogen.sh but that also failed. Any pointers would be appreciated!! thanks On 09/09/2012 06:45 AM, pd-list-request(a)iem.at wrote: > Message: 5 > Date: Sat, 8 Sep 2012 20:13:41 -0700 > From: Miller Puckette<msp(a)ucsd.edu> > Subject: [PD] another day's raspberry pi experiences > To:pd-list@iem.at > Message-ID:<20120909031341.GJ1555(a)stripe.ucsd.edu> > Content-Type: text/plain; charset=us-ascii > > Hi again- > > Having fooled with the Pi a few more hours I think I now have a better idea > how the thing behaves. > > The main difficulty I've had is that having a USB keyboard and/or mouse > connected to the Pi seems to conflict with USB audio devices.

Frequency Analysis of an existing sound file recorded in a text file
by Emin Durak 15 Sep '12

15 Sep '12

Hello! Might look like a typical beginner question, but I'd like to have some tips on how to do the above mentioned task most efficiently?? I have a sound file that I need to extract all the data and record in a file; ideally by building a txt file with full of each microseconds and equivalent frequency range. It is to be used to construct another sound file from that data, as well as other sorts of applications such as GEM. It seems to be that [fiddle] object is the most conventient, but I'm open to any suggestions to develop it further... Thanks sincerely, Emin

[pix_film] breaks Pd
by João Pais 15 Sep '12

15 Sep '12

Hi, I'm trying to load a film into [pix_film], but that makes Pd shut down. Is there a way of sending a bug report or something? The system is XP, both Pd 0.42-ext and 0.43-ext. It makes the same with any film file, either from the Gem examples, or something else. Thanks, jmmmp

... and the battle with IT begins
by m.e.grimm 15 Sep '12

15 Sep '12

my rant is as follows when making a request to have pd-extended 0.43.1 installed on the teaching station i get: "Mark: For obvious reasons, we won't install a beta release of software in a production environment. The current latest production release will be installed." which im fine with 042.5 but this is just more annoying than anything else. am I alone or do others on this list in Universities battle with IT on a daily basis? i am suspecting im not alone..... is it the word "BETA" that is so bothersome? what is a "production environment"? am i not producing something? -- ____________________ m.e.grimm | m.f.a | ed.m. megrimm(a)gmail.com _________________________________

another user experience with raspberry pi
by Cyrille Henry 14 Sep '12

14 Sep '12

hello, Antoine and I did few test on a raspberry pi. to summarise, we did : - use standard raspbian installation - modify /etc/security/limits.conf as sugested by miller (adding : "* - rtprio 99" and "* - memlock 1000000000") - sudo apt-get update, upgrade and install git tk8.5-dev libasound2-dev git clone git://pure-data.git.sourceforge.net/gitroot/pure-data/pure-data copy the configure file from pd 0.43 cd src , ./configure, make and sudo make install adding -rt in pd startup flag using the integrated HDMI audio out gives 20ms audio buffer minimum to avoid click, when cpu is unused. with nusmuk-audio analog synth emulation (that use 35% cpu when the oscilloscope is removed), 25 ms buffer give no click, few can appear when moving windows. with an old usb soundcard (edirol ua-1A), 10ms audio buffer is enough to avoid click even when moving windows. (still using the same example patch) (44100 or 48000KHz, block size of 64) in both case, audio input must be disable, we did not manage to use it properly. details instruction (in french) can be seen on Antoine blog : http://antoine.villeret.free.fr/?p=359 cheers Cyrille

[PD-announce] Xth Sense: instrument, code, schematic, tutorial on-line now
by Marco Donnarumma 14 Sep '12

14 Sep '12

Heya all, I've been away from the list finalizing the release of the Xth Sense and other major commitments. The Xth Sense (software and hardware) is finally available on-line, get binaries, DIY documentation, and tutorials at: http://res.marcodonnarumma.com/projects/xth-sense/ The digital interface is developed in Pd; there's a main software for the computation of incoming muscle sound (and virtually any sound input), and the xth-sense-lib, a collection of 120 objects (and help files) ranging from specific muscle sound methods, to everyday Pd patching needs. It also includes a lot of GUI stuff, to facilitate building things. Wanna the source? Here you go: https://github.com/marcodsad What is the Xth Sense? "**is a biophysical musical instrument. You can build your own and produce music with it using the sound of your muscles. It is free and open source, and it was named the “world’s most innovative new musical instrument” by the Georgia Tech Center for Music Technology (US, 2012). Its name is spelled ecsth sense (not tenth sense!). But it’s way easier to call XS." With the XS you can also control other software on your machine (video, audio, light systems, etc.), send Voltage output to hardware, or control a prosthetic arm. Hacks are encouraged by the design of the instrument itself. For some ideas see: http://res.marcodonnarumma.com/projects/xth-sense/#get-started We have a (newly born) user's forum, courtesy of Create Digital Music/Motion; the forum lives at: http://createdigitalnoise.com/categories/xth We are on also on Facebook (imagine!): http://www.facebook.com/XthSense if anybody works with it, let me know! We have users and works in Australia, Sweden, US, UK, Ireland, Spain, Vietnam, Germany, Russia, Netherlands, and Italy, so far :) hope it is useful to some of you, cheers, -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.
