Gridflow+ L2Ork pd-extended (was: L2Ork pd-extended release candidate 1 now available)
by ALAN BROOKER 27 Nov '10

If I press ctrl+1 to create an object that's when it crashes out, opening pd patches is fine but if I try to edit them then a crash will occur as well. Also opening Grdiflow help index causes crashes without loading the index patch at all On Sat, Nov 27, 2010 at 5:43 PM, Ivica Ico Bukvic <ico(a)vt.edu> wrote: > This looks like an incompatibility between tagged moving of an object and > something in the gridflow. > > Does this occur with any object or just some specific object(s)? > > Mathieu, The offending call should be the same like the Regular call except > that is this place is using a tag.

Most simple interfacing of 1 or 3 hardware switches (with [comport]?)
by András Murányi 27 Nov '10

27 Nov '10

Dear List, i wish to connect a simple 3-switch foot-switch to Pd, and i was hoping i could do it with [comport], but when digging into it, i got slightly disheartened... can you help me how to do this, at least with 1 switch, without building some complicated interface? It's not a pedal with pots, just "push-buttons" (not even real switches which would stay on or off). Thanks, Andras

Compiling pd-extended externals
by Ivica Ico Bukvic 27 Nov '10

27 Nov '10

Hans, I just finished recompiling externals using L2Ork iteration of Pd, according to the script that came with the Pd-extended's externals/ folder. It appears with the "make install" command all externals have been built inside the build/lib/pd/extra (with doc/) folders. Is this now simply a matter of copying these over into the /usr/lib/pd/extra and doc folders respectively or is there another step in between? Please advise. Many thanks! Best wishes, Ico

selecting based on vectors
by Menno van der Woude 27 Nov '10

27 Nov '10

Hello, using [pdp_mgrid] I am trying to get a geometric form on a GEM window to follow the movement the camera sees. This is fairly easy, cause [pdp_mgrid] outputs int numbers for x and y coordinates, which I can use to have gem draw a circle/square on the appropriate place. So far so good. Now, I wish to have a movement be 'followed' by white squares, that quickly fade in and then slowly fade out. Using a grid of 7 by 7, this means I need to create 49 squares, that, when triggered, will fade in to white, and the fade to black, each in a separate place. I do not knwo a better way to do this. Although inconvenient, it's fine for this relatively low number of objects. My problem is with using the vector info from [pdp_mgrid] to choose from 49 options. Adding/multiplying, etc, x and y is problematic, cause it results in identical numbers for positions that should be unique. Any ideas on how to use vector info (meaning, in this case, x and y info) to select unique objects? Or is there a more efficient way to achieve the desired effect? Maybe it is even a bad idea to combine pdp and gem? See attached patch for an impression of what this should become like. I have not yet completed building this, since I ran into these troubles. Bye!

Analysing voice prosody (Problem Level: Moderate)
by sisil mehta 26 Nov '10

26 Nov '10

Hello, I'm trying to do prosody analysis of a person's voice. So basically I need to take in the voice from the mic and analyse: pitch, amplitude, loudness. I'm new to PD and wondering if someon could point me to the externals/tutorial which explains how to do so in PD (most of the tutorials I've seen in PD were for analysing music. Do the same analyses apply to voice as well?) After googling I the fiddle~ external and was wondering if that can be used to analyse pitch and amplitude of voice. I found these libraries for Max/Msp here ( http://cnmat.berkeley.edu/downloads) which let me find pitch/loudness /amplitude. Is there somthing similar for PD? Thanks a lot -- Regards, Sisil Mehta <https://sites.google.com/site/sisilmehta/> PhD Program@Georgia Tech

oo, Liepaja has a wonderful seashore and some huge hidden ruins of military bunkers... you should have had a walk around!

Btw, I am teaching PureData and GridFlow at Aix-en-Provence this week. It's reserved for students of the school, so, I didn't announce it, but it's just to say that it's happening. Total duration is between 20 and 30 hours long, approx. _______________________________________________________________________ | Mathieu Bouchard ------------------------------------- Aix-en-Provence

PD, Linux and USB multichannel interface
by Carlo Benzi 25 Nov '10

25 Nov '10

Hi! I have a question: is there a USB multichannel interface (for example 8 in - 8 out) running under ubuntustudio or studio64 (processor: Intel Pentium M 740 with 1 GB ram)? I'd like to buy it in order to use Pure Data with this equipment. Thanks a lot for your help! Best greetings Carlo

Gridflow: CPU of #see
by Olivier Heinry 25 Nov '10

25 Nov '10

Hello matju, how do #see and an #out window the same size, say 640x480 in RGB colorspace, compare in terms of CPU consumption? On my Core2duo laptop, #see makes the CPU jump real high. Potsdamer greetings, OH
