changing the position of arrays dynamically
by peiman khosravi 31 Dec '13

31 Dec '13

Dear all, I have a bunch of arrays in a subpatcher and would like to be able to dynamically chose which one is visible in the parent window. Is this possible? I'm trying to mimic the feel of superimposed graphs, where the 'active' graph can be changed dynamically. Normally I wouldn't bother with this but there are about 20 arrays that act as parameter automations, and my 13 inch screen doesn't provide enough room! I thought of 'pos' but it seems that the array object doesn't understand the 'pos' message. Many Thanks Peiman *www.peimankhosravi.co.uk <http://www.peimankhosravi.co.uk> || RSS Feed <http://peimankhosravi.co.uk/miscposts.rss> || Concert News <http://spectralkimia.wordpress.com/>*

Mess with Pd installation on Linux
by Alexandros Drymonitis 30 Dec '13

30 Dec '13

I'm a newbie in Linux and have installed Ubuntu 12.04. I have a running Pd vanilla (0.44-3), but wanting to use jack, I got the latest version (0.45-4) and recompiled. My steps for both versions were: extract the downloaded file to my home directory (I've made a directory there called 'apps'), and cd to that directory, ./autogen.sh then ./configure --enable-jack (btw, at the end of configure, there was a JACK....no), then make and sudo make install. If I type pd in a terminal I get Pd-0.44-3 working fine (without jack). My question is, how do I get to open Pd-0.45.4? Is pd a symbolic link pointing at the pd binary? If so, how do I make it point at the newer version? And where is this link located? Also, in the beginning I installed Pd-extended but then uninstalled it, and had some compiling efforts with vanilla that didn't work. Going through my system, I see that there are some pd files in /usr/bin/, in /etc/alternatives/, in /usr/share/man/man1, some of which are broken symbolic links (some from the extended installation), maybe some places else too...with a proper compilation aren't things supposed to go to /usr/local/ ? Should I remove any file that's in the directories above?

Here's another cleanup of something I made for a recent performance. Like martha~, it's a Pd-vanilla abstraction, so ready to use on any platform. The idea is to make multiple time-stretched/transposed copies of the live input that trail behind as a kind of detuned halo (or with the right settings, a dense and disgusting mush). A simplified version of the I07.phase.vocoder.pd doc patch is at its core, so this is mainly about taking care of all the buffering, polyphony, and auto-spawning of streams. http://williambrent.conflations.com/pages/research.html#streamStretch -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com

[PD-announce] HoaLibrary for PD - High Order Ambisonics Library
by Pierre Guillot 29 Dec '13

29 Dec '13

Hi, The CICM is pleased to share the first release of HoaLibrary for Pure Data. HoaLibrary is a collection of C++ classes, FAUST functions and objects for Pure Data, Max and VST destined to high order Ambisonics sound reproduction. HoaLibrary allows musicians and composers to synthesize, transform and render sound fields in a creative and artistic way. This library facilitates the understanding and the appropriation of key concepts of Ambisonics. Thanks to original graphical interfaces a lot of new signal processings are allowed like diffuse sound field synthesis, perspective distortion or spatial filtering. HoaLibrary is free, open-source and made available by CICM, the centre of research on musical composition and computer science of the Paris 8 University. Objects: hoa.decoder~ : An ambisonic decoder (ambisonic, binaural, irregular configurations). hoa.encoder~ : An ambisonic encoder. hoa.map~ : An ambisonic sources spatializer. hoa.delay~ : An ambisonic sound field delay. hoa.freeverb~ : An implementation of the freeverb algorithm for Ambisonics. hoa.grain~ : An ambisonic granular synthesizer. hoa.map : A GUI to spatialize sources on a map. hoa.meter~ : A circular meter with sound field descriptor. hoa.optim~ : An ambisonic sound field optimization. hoa.pi : A good pi number. hoa.projector~ : A plane wave decomposer. hoa.recomposer~ : A plane wave recomposer to harmonics domain. hoa.ringmod~ : An ambisonic sound field ring modulation. hoa.rotate~ : An ambisonic sound field rotation external. hoa.scope~ : An ambisonic harmonic scope. hoa.space : A GUI to design ambisonic space. hoa.space~ : A plane wave spatial filter. hoa.wider~ : An ambisonic fractional orders simulator. Release: http://www.mshparisnord.fr/hoalibrary/en Sources: https://github.com/CICM/HoaLibrary Feedbacks are welcome. Thanks.

Re: [PD] Problems with sound after installation

Thanks. Dsp is on, yes. I know that this is not the proper forum for jack-related questions but how to verify that jack is working correctly? There are no error messages.

headroom in Pd
by Alexandre Torres Porres 29 Dec '13

29 Dec '13

Hi there, where can I find info about headroom and clipping on Pd. Or can anyone tell me quickly how it goes? Does it always really clip over a maximum of 1, or is there some headroom? Does it depend on the audiocard or something? thanks

Problems with sound after installation
by Peter O'Doherty 29 Dec '13

29 Dec '13

Hi, I've just installed pd and am having trouble with the audio setup. I think the problem lies with pd and not jack but am not sure. When I do "Test Audio and Midi..." the following error appears in red on the gui: "dio I/O error". The test tones are silent. Here is my setup: Ubuntu 13.04 pd 0.43.4-extended qjackctl 0.3.10 libjack-jackd2-0 libjack-jackd2-dev Jack is selected from the list oss, alsa, portaudio and jack. Thanks for your help.

why is the -jack flag not working?
by Alexandros Drymonitis 29 Dec '13

29 Dec '13

Following the FLOSS manuals, I'm trying to open Pd with the jack flag and I get the 'usage:' message and jack is not included in the audio configuration flags. These are the audio configuration stuff audio configuration flags: -r <n> -- specify sample rate -audioindev ... -- audio in devices; e.g., "1,3" for first and third -audiooutdev ... -- audio out devices (same) -audiodev ... -- specify input and output together -inchannels ... -- audio input channels (by device, like "2" or "16,8") -outchannels ... -- number of audio out channels (same) -channels ... -- specify both input and output channels -audiobuf <n> -- specify size of audio buffer in msec -blocksize <n> -- specify audio I/O block size in sample frames -sleepgrain <n> -- specify number of milliseconds to sleep when idle -nodac -- suppress audio output -noadc -- suppress audio input -noaudio -- suppress audio input and output (-nosound is synonym) -listdev -- list audio and MIDI devices -oss -- use OSS audio API -alsa -- use ALSA audio API -alsaadd <name> -- add an ALSA device name to list -pa -- use Portaudio API (default audio API for this platform: ALSA) I've already started jack with the -d firewire flag, and it seems to be ok, but Pd won't let me use this flag. Any ideas? I'm on Ubuntu 12.04 and Pd-0.44-3
