Both examples work very well and i thank you all. Tom's example is a little closer to what i was envisioning. i always forget about route! cheers~ and thanks to all Pat On Wed Apr 19 18:57:16 EDT 2006, Hans-Christoph Steiner <hans(a)eds.org> wrote: > > And if you want to have bi-directional connections, you can use > [netserver] and [netclient]. > > .hc > > On Apr 19, 2006, at 8:15 PM, Thomas Ouellet Fredericks wrote: > >> You can also send a list like this: >> >> >> [pack f f f f f f f ] >> | >> [send $1$2 $3 $5 $5 $6 $7< (this is a message box) >> | >> [netsend] >> >> >> [netreceive] >> | >> [unpack f f f f f f f] >> >> Tom >> >> On 4/19/06, Max Neupert <abonnements(a)revolwear.com> wrote: >>> [send fader $1] >>> \ >>> \ [send data $1] >>> \| >>> [netsend n] >>> >>> ----------------- >>> >>> [netreceive n] >>> | >>> [route data fader] >>> >>> >>> >>> Am 19.04.2006 um 02:52 schrieb <bigswift(a)cox.net> >>> <bigswift(a)cox.net>: >>> >>>> >>>> hi >>>> >>>> i am fooling with netsend and netreceive on linuxppc pd-38-4. >>>> i always have problems with getting this working how i woul d >>>> like, >>>> but i want to make sure i can do what i am intending.

Big distortion ?
by Olivier Revollat 20 Apr '06

20 Apr '06

Hi, I am looking for an abstraction/external (or even a LADSPA plugin loaded in plugin~) to have a big distortion sound in pure data (for an electric guitar).

Re: [PD] PDP and quicktime pdp_qt
by Dave Leith 20 Apr '06

20 Apr '06

Hi and thanks for your assistance Well sorry to be stubborn and a pain but I still can't get any codec to work. I had already tried all codecs but I re-tried them all again making sure to follow your suggestions. I used both Quicktime 6.5 Pro and Jitter to create the .mov files. I also experimented with argb and YUV. Always the same. Some examples below: As well I experimented with other RC versions (RC5,6, and the newer .39 tests). Version RC7 would recognize most codecs as OK in the console, then crash after about 30 sec. The newer .39 test don't correctly load PDP/PiDiP. Info below as well: I removed everything and reinstalled the OSX PD and X11.

netsend netreceive help
by bigswift＠cox.net 20 Apr '06

20 Apr '06

hi i am fooling with netsend and netreceive on linuxppc pd-38-4. i always have problems with getting this working how i woul d like, but i want to make sure i can do what i am intending. I would like to netsend 8 seperate number values from different ctlin messages. Is this possible? the example shows [send foo $1] | [netsend] and i get connected and netreceive prints tcp foo ### as i move the number box what i would like to have seven seperate values sent but i am sure how to do this. do i need to have seperate netsend & netreceive objects? thanks in advance for any help. pat Patrick Pagano Digital Media Specialist University of Florida Digital Worlds Institute 352-294-2082

concatenate+arduino
by Thomas Ouellet Fredericks 20 Apr '06

20 Apr '06

Here are two little abstraction I made, one to communicate with an Arduino an another to concatenate a list. Both require Zexy. Arduino.pd also requires comport and the included text file "ascii.txt". Arduino.pd is a preliminary exampe and will be further developped. http://interactivite.danslchamp.org/fichiers/arduino_pd.zip and http://mrtof.danslchamp.org/pd/list-concat.zip Tom

usb RFID reader and pd
by Tristan d'Estrée Sterk 19 Apr '06

Antonios, I'm currently looking into RFID too - check this out - it's an RFID radar that lets you read the locations of multiple tags for 100m with a 0.5 meter accuracy. see: http://www.rfid-radar.com/

Re: [PD] Cross correlation using FFT
by Jamie Bullock 19 Apr '06

19 Apr '06

Hi chuck, Thanks a lot for putting this together. I was so near, but yet so far with regard to getting it right. I hope you don't mind, but I have incorporated your code from xcorr~ into the flib library. I thought this would make sense since there is already cross correlation in there. Now [cc~ f] performs frequency domain cross correlation using your algorithm, cc~ without any arguments (or with a delay time as an argument) performs time domain cross correlation based on work by Phil Bourke. I have also removed the dependency on fftw; you might think this is crazy, but for the moment at least, I'd like to stick with Mayer. Thanks again for your help. Jamie On Mon Apr 17 17:24:24 CEST 2006 Charles Henry wrote: Sorry it took me so long to send the external and code..... It just got me thinking that I was doing something really wrong here, but I think I've got it straightened out now. The implementation here does a pretty good job of using xcorr~ in overlapping blocks, like block 256 2. So, we have the two signals, as described before sig1 |/\/\/\/\|/\/\/\/\| 2N non-zero samples sig2 |----/\/\|/\/\----| N non-zero samples, in the middle We can do a running calculation of the cross-correlation, using overlapping blocks. (Don't reblock the output, it won't work that way.) |/\/\/\/\|/\/\/\/\| |----/\/\|/\/\----| |--------|/\/\/\/\|/\/\/\/\| |--------|----/\/\|/\/\----| And the result is that when we add up the results of xcorr across blocks we get a running calculation of the cross correlation. So, I also created two others to help here. intbb~ which integrates (stably) between blocks (which was no doubt unnecessary) and maxm~ which picks out the maximum value, and its location in the vector between bounds, e.g. [maxm~ -256 256] picks out the location of the maximum value, closest to the "origin" of the vector, in either the last 256 samples of xcorr~ or the first 256 samples of xcorr~ again sorry for the long delay chuck

multiio vs. arduino?
by João Miguel Pais 19 Apr '06

19 Apr '06

Hi, I searched the archives, but couldn't find any informations about the thema. I'm considering buying an arduino board. I would like to hear something from the participants about that one vs. the multiio. Important topics would be: - ease of use (what's necessary to install, etc) - number / compatibility of sensors - function in both windows and unix - price - behaviour on pratical situations (performances, concerts, installations...) - and any other that you can think of. Thanks again, joao -- Lugostr. 14 79100 Freiburg i. Br. Deutschland +49 (0)761 7074997 jmmmpais(a)googlemail.com http://www.puredata.org/Members/jmmmp

Pix buffer?
by Jonathan Goodwin 19 Apr '06

19 Apr '06

Good Afternoon everybody, I'm trying to find the best way to use pix_snap2tex and pix_chroma_key in conjunction. Basically, I want to take snaps from a webcam feed, process them and key the results over a regular video file using pix_film etc. Preferably without having to actually display the raw cam feed. My problem is that the snap2tex is grabbing images of whatever is displaying in the GEM window, rather than from a specific feed only. I.e. The webcam. I'm sure there must be a way to chose where to grab from? I think from what people on this list have said it may be with the pix_buffer object but I really can't get to grips with how to use this. If any one can give me some pointers on this, or any other way I could approach this, I'd be most grateful! Thanks.
