GUI Panels
by Dominic Pflaum 06 Oct '10

06 Oct '10

Is it possible to have panels on PD which can be switched? I want to make a GUI that will have in total 1600 switches. Obviously this will not all fit on one screen. Is this possible, and are there any examples of such things? Many thanks, Dom

namecanvas obsolete? Why? Re: Dynamic Graph on Parent
by brandon zeeb 05 Oct '10

05 Oct '10

According to [namecanvas] help, this object is obsolete? How else can one send a message to one and only one abstraction without using namecanvas? Is there the concept of 'this'? The example below will send a message to all patchname.pd abstractions, this is not what I think most require: [message( | [s pd-patchname.pd] On Wed, Sep 29, 2010 at 10:30 PM, brandon zeeb <zeeb.brandon(a)gmail.com>wrote: > Oh, that is awesome!

I was working on a Sound renderer project made in PD and to reduce the latency, we wanted to write the module in C, implementing all the features. Is their a simple way of doing so? If so, please do help Ankur

GEM pix_image and Ubuntu problem solved by thread 0 message
by Dario Pedrioli 05 Oct '10

05 Oct '10

Hi all, we are under PD 0.42.5 - GEM 0.92.3 - Ubuntu 9.04 - NVIDIA Gtx 260 (proprietary driver 256.44) we have a patch (a sort of circular slide show with the images reflected an a plane) with 12 pix_image loading images of 1024 px *1024 px The problem was: half the time we launch the patch some of the pix_image (random number) fail to load the image (gray rectangle). After few hours of debugging and web search we've found a workaround: send a [thread 0( message to every pix_image to prevent the start of a new thread for loading the images. Someone know why this happen? Anyhow, with this workaround we can display 120 images without problems and now we are very happy (after some concern) - Many thanks to all you pd and gem boys!

Shuffling arrays
by Andrew Faraday 05 Oct '10

05 Oct '10

Hey Guys I've recently come across the .shuffle method in Ruby which randomly re-orders the content of an array. Does anyone know of a way to do this in Pd, that is, either change the order of notes within an array or output them in a random order (without repeating any part of it)? Help would be appreciated Andrew

[counter] documentation in help file is incomplete
by Jeffrey Concepcion 05 Oct '10

05 Oct '10

I tried to add this to the bugtracker but it doesn't show up, i must have done something wrong. There is no documentation on the outlets of the [counter] object, so here's what I found: outlet 1- outputs number + bang outlet 2 - (when counting down) outputs bang when reaches 0 and when starting the countdown over outlet 3 - (when counting up) outputs a 1+bang when it reaches max value and 0+bang when starting over; (when counting up & down) same as when counting up outlet 4 - (when counting up) outputs the number of times the secuence has been completed + bang hopefully this can be added (better written, of course) to the help file. -- www.epicjefferson.com www.avmachinists.org Puerto Rico based Art Collective/ Non-Profit Org

GUI speed
by András Murányi 05 Oct '10

05 Oct '10

Dear List, I'm trying to investigate why does a larger patch slow down the GUI so much much. When opened, CPU load goes to 40-50% (when minimized, goes back to ~20%), when i load values from sssad CPU goes up to 60-70% and stays there, and when i start the metro it goes even higher (not 90 or 100% however) and virtually unresponsive. Please take a look at the attached image and tell me if this is normal with a patch of this visual complexity. Make no mistake, the pd core maintains a decent 3-10% CPU load, its pd-gui which cannot handle the party. This is an ongoing problem which prevents me from actually *making music* with my patch. Tried to add the GOP abstractions to the canvas one by one, it seems that CPU load goes up by each element, i mean i couldn't find a "guilty one". Pd 42.5, Ubuntu Lucid, Compiz (<-- does it matter?) Thanks a lot for any advice! Andras

ugly fonts under pdextended 0.42.5
by michael noble 05 Oct '10

05 Oct '10

hi all, I was testing out the new pd-extended builds over the weekend and found a common problem with the Lucid, Maverick and Debian builds . No matter what I tried, I could not get pdextended to load with anything other than the chunky default font, sans anti-aliasing. I have Dejavu family fonts installed on all the test systems. I also tried using the -font-face switch but it didn't seem to make a difference. At first I thought it was something I was doing, but after having the same problem on three different systems, I am now wondering if anyone else is having this issue. Am I missing something blindingly obvious? -michael

Res: Res: music made with Pd
by Eduardo Patricio 05 Oct '10

05 Oct '10

Thanks, Pedro The main ideia is quite simple. I'm using 5 phase-vocoder modules to manipulate small audio samples (using pd tables). The x joystick axis is directly connected to the positions in the tables (so I have location control). The y axis controls the pan. The independent pitch control is mapped to the extra axis I control with my left hand (in the back of the joystick). As I have the same controls for all the 5 samples, there are some options to create "diversity" and variation. Each module has some very simple (but effective) resources: invert pan (then you can have symmetric movements), attack and release times, momentary or non momentary behavior for the action buttons (the 5 top buttons on the logitech attack3 joystick enables the pv modules), intensity of pitch behavior, and pitch lock. The use of audio samples with different morphological qualities can lead to interesting results, but here in 'discos de cobre' I'm using very similar percussion samples (screenshot). I also have a reverb that can be applied to the resulting stereo image (not available for the multichannel out), and a simple delay and a simple granulator that can be programmed before the performance using a kind of "wet-and-dry-time-based-slide-score". Additional feature: 4 loop players to trigger pre-recorded material. That's it. I hope I have being clear enough. my best Eduardo _____________________________________ Eduardo Patrício http://www.eduardopatricio.com.br (41) 8434-0480 ________________________________ De: Pedro Oliveira <hello(a)partidoalto.net> Para: Eduardo Patricio <epatricio(a)yahoo.com> Cc: pd-list <pd-list(a)iem.at> Enviadas: Terça-feira, 5 de Outubro de 2010 3:28:47 Assunto: Re: [PD] Res: music made with Pd Hey there, I saw your first video and it is a quite interesting sonic result.

problem in compiling puredata_opencv
by Adityo Pratomo 05 Oct '10

05 Oct '10

hi there, i was compiling puredata_opencv this morning for a school project. however, i got this error while trying to compile it: configure: error: you need to install opencv library (libcv) i already followed all the sequence of compiling it. I'm on a Mac, so I already put the opencv framework on /Library/Frameworks folder, and I already downloaded the pd 0.42.5 and Gem 0.92.3, because i'm using the latest pd-extended. any suggestion why is this happening? Or should I just use the previous pd-extended so that I can use the available packages of puredata_opencv? Thank you very much for any help :) -- mataharipertama.wordpress.com kotakmakan.multiply.com
