The Game of Life
by Andrew Faraday 12 Dec '10

12 Dec '10

Hey All Bit of an early Christmas present. It's a pure-data based, 16x16 version of Jon Conways "Game of Life" (http://en.wikipedia.org/wiki/Conway%27s_Game_of_Life). Perhaps the geekiest thing I've ever done. It's all zipped up because I've used a few abstractions, just uncompress to a single folder and open OpenMe.pd Would love to hear what you guys think of this. Particularly interested in: * Does anyone know if it's been done in puredata before? Can I get hold of it? * Is it well documented enough? * Does it work on different operating systems (was made on ubuntu (netbook remix) so some of it may not transfer)? * How might you improve on this? I may, in the longer run, be planning to use this for a generative music patch. Don't know if that means anything to you. Cheers Andrew

Pd+pachube+python
by FernandoG 12 Dec '10

Hi I am trying to comunicate pd with data coming from pachube (www.pachube.com) using a python script. The script ask for data from pachube web and convert the data to OSC protocol. Then the OSC mesagge is sent to pd. Pd recibe the OSC mesagge but something is wrong when unpack and route the data. Data can not get in a number box object, this error mesagge is diplayed in console: error: gatom: no method for '1' The python script # to receive data import urllib2 # to send on with OpenSoundControl, OSC from simpleOSC import * import time initOSCClient('127.0.0.1', 57110) while 1: data=urllib2.urlopen(' http://api.pachube.com/v2/feeds/2791.csv?key=hereyourcode') for l in data: d = l.strip().split(",", 2) print d sendOSCMsg('/test/num',d[0]) sendOSCMsg('/test/val',d[2]) time.sleep(5) # wait here some secs the patch #N canvas 599 0 450 476 10; #X declare -lib mrpeach; #X obj -217 25 import mrpeach; #X obj -220 112 unpackOSC; #X floatatom -219 277 5 0 0 0 - - -; #X obj -214 148 routeOSC /test; #X obj -191 348 print; #X floatatom -150 281 5 0 0 0 - - -; #X obj -219 66 udpreceive 57110; #X floatatom -92 290 5 0 0 0 - - -; #X obj -204 205 routeOSC /val /num; #X connect 1 0 3 0; #X connect 3 0 8 0; #X connect 6 0 1 0; #X connect 8 0 2 0; #X connect 8 1 5 0; #X connect 8 1 4 0; #X connect 8 2 7 0; any idea? thanks

midiin
by Laurent Willkomm 12 Dec '10

12 Dec '10

Hello list, Using pd-extended 0.42.5 on Ubuntu Maverick 64 bit with alsamidi, I notice that [midiin] does not deliver MIDI Clock/Start/Stop/Continue messages. MTC, Sysex, End of Sysex are working. Kmidimon can see the clocks, so it's no alsa problem. Is this known/intended/bug ? L.Willkomm Noise Watchers Luxembourg

Helmholtz Motion Verifier
by Ludwig Maes 12 Dec '10

12 Dec '10

How would one (and how hard or easy would it be) write a patch which does the following: Instruct the user to play a sustained note on the violin; then give feedback about how accurate Helmholtz motion is achieved; Could we measure how short the transient takes from nonHelmholtz motion to helmholtz motion? How about changing from a note on one string to one on another, ... Could we write a patch that trains the user to minimize install and end times for helmholtz motion and to somehow show a level of periodicity during the systaining period?

Re: [PD] Helmholtz Motion Verifier
by Collin Oldham 12 Dec '10

12 Dec '10

Interesting idea! Might be a good idea to use a pickup, since the body resonances of the instrument will smear the helmholtz motion from the signal a bit if you use mic. Regarding your second question: There will be no phase lock across 2 strings, which is why it is possible, and even likely, that double stops can be played out of tune! Can such a patch be written in Pd? Certainly! Collin

Gem: drag'n crop
by Max 12 Dec '10

12 Dec '10

hi list, here is a Gem riddle: make a box which you can't see because it is a cropped part of the background pasted at the exact position and showing the perfectly cropped part of the background. this is how far i could do it, but now i need more wisdom: m.

Segfault with less libs
by András Murányi 11 Dec '10

11 Dec '10

Dear List, i've made some clanup in my .pdsetting and .pdextended files and removed the paths and libs not needed for me. Now i get segfault when i load my patch. Could it because of a missing lib (like i have deleted a line i shouldn't have) and if so, how come? How can i debug this? With -verbose, i don't get the segfault but the patch never loads... Andras

pix_motion_sector on linux
by Yvan Volochine 10 Dec '10

10 Dec '10

hallo ! I stumbled upon this thread http://www.mail-archive.com/pd-list@iem.at/msg34546.html and I'm wondering if it could be possible to build pix_motion_sector on linux ? the Makefile is osx only (and I'm a n00b and dunno which gcc flags should replace xcode ones etc). cheers, _y

wav file export from table
by William Brent 10 Dec '10

10 Dec '10

Hi all, Do any of the libs in Pd-extended have an object for writing audio from a table directly to a wav file in non real time? -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com
