sound convolution / phase vocoder
by Jean-Marie Adrien 29 Jul '18

29 Jul '18

Hello everyone Still migrating to 64 bits from pd-extended, external by external in this process, tying to use vintage objects such as pvoc~ and partconv~ which came in bsaylor, dll format : found everything via decken, including libdir but cannot get it to work sorry for this question : any hint to have this work with pd 47-64 bits on mac 10.11 ? thanks JM

Japanese language problem
by S.E.P. 29 Jul '18

29 Jul '18

Hello, Pure Data throws the following error when I try to open up Media>Audio Settings: (Tcl) UNHANDLED ERROR: extra characters after close-brace while executing "lappend audio_indevlist {}CN (Realtek High Definition} global audio_outdevlist; set audio_outdevlist {} lappend audio_outdevlist {Xs [J ..." ("uplevel" body line 2) invoked from within "uplevel #0 $docmds" My OS is in Japanese and, according to this page ( https://drugscore.blog.fc2.com/blog-entry-194.html), I need to change the language setting of my OS to English (presumably other European languages would work, since I've used PD on a German-language system) to bypass this system. Just wondering if there was another fix- it's not a big deal for me to change the settings, but maybe for Japanese people interested in PD it would be. Best, Elliot

[PD-announce] faustgen~ - the FAUST compiler embedded in a Pure Data external
by Pierre Guillot 28 Jul '18

28 Jul '18

Hi, The CICM and the GRAME are pleased to announce the faustgen~ object for Pure Data. Faustgen~ is an external object with the FAUST just-in-time (JIT) compiler embedded that allows to load, compile and play FAUST files within the audio programming environment Pure Data. FAUST (Functional Audio Stream) is a functional programming language specifically designed for real-time signal processing and synthesis developed by the GRAME. The FAUST JIT compiler - built with LLVM - brings together the convenience of a standalone interpreted language with the efficiency of a compiled language. The faustgen~ object for Pure Data is a very first version with elementary features, help and contributions are more than welcome. The faustgen~ object is available for Linux, Mac and Windows (64-bit) via Deken (v0.4.1) or via the github repository: https://github.com/CICM/pd-faustgen/releases. We hope that you'll enjoy this project! > > FAUST: http://faust.grame.fr GRAME: http://www.grame.fr CICM: http://cicm.mshparisnord.org > _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

triggering [print~] faster than every 64 samples
by mario buoninfante 28 Jul '18

28 Jul '18

Hi, I'm trying to trigger [print~] every sample. in the same patch I'm using [block~ 1 1 1] to change the block size and [metro 1 1 samp] to trigger [print~]. but I noticed that [print~] is yes printing 1 sample at time (in accord with the block size) but only every 64 samples. so it receives a bang every sample but prints every 64 (default block size). can you guys help me understanding why? I'm pretty sure I'm missing something here :D cheers, Mario

Re: [PD] FANN external for neural nets
by Dan Wilcox 25 Jul '18

25 Jul '18

I would suggest adopting it and add it as an "ann" repository in the pd-externals Github group: https://github.com/pd-externals <https://github.com/pd-externals> We can add you as a member. With pd-lib-builder included, it would then be easy for more people to experiment and keep up to date. I would start by pulling the original commit history from IOhannes' SVN import repos: http://git.puredata.info/cgit/svn2git/libraries/ann.git/ <http://git.puredata.info/cgit/svn2git/libraries/ann.git/>. Then tag the last commit as version 1.0, if it doesn't hav one already. Next, bring in your changes and bump the version to 2.0 and we go from there. One of the issues with Pd-extended was having such a large number of externals (which is great!), but slowly losing maintainers of many of them (which is hard for a small number of devs to deal with). With this transition to deken, we're seeing which externals people really want to keep up, so the code gets resurrected and the work gets distributed. This is a healthy sign for any external :) > Any thoughts on this? Is there another neural net package for Pd that I'm > totally ignorant of?

Re: [PD] [PD-announce] Camomile v1.0.6 - LV2 support, PdStalFx, Audio Buses, etc.

Thanks, it's really appreciated! There is a thread on the pd forum where I speak about it ( https://forum.pdpatchrepo.info/topic/11242/camomile-v1-0-1-an-audio-plugin-…). One idea could be to create a parallel distribution, some kind of Camomile-extended, but I'm not sure that's the good approach (in fact, I'm pretty sure it's not). I would prefer to have the dynamic libraries alongside the patches and, if necessary, to let libraries devs to manage the multiinstance/multithread support (most of the time it's not hard to do) and offering a special version of their libraries. Anyway, for the first approach I can make an example with the freeverb external and let people do the same with their libraries if they want to have their own Camomile distribution. And if you want to have a first look, the first step would be to compile Camomile, it's pretty easy and straightforward (on Mac there is one solution that compile everything and on Linux one makefile), see the readme: https://github.com/pierreguillot/Camomile/blob/master/README.md#compilation. Cheers

FANN external for neural nets
by William Brent 25 Jul '18

25 Jul '18

Hi all, I wanted to try out Davide Morelli's [ann_mlp] object, which uses the FANN library for neural nets, and found that some of the FANN functions it uses no longer work as of FANN 2.0. I decided to take it on and update things to get basic functionality going, and then went further to add access to additional/new FANN options and create an in-depth help file as well. It's been useful to me in timbre classification problems, and if there isn't already a current go-to neural net option for Pd that I just don't know about, I feel like this would be a great tool to put out there again. I'm happy to share this source code/help file, but I wanted to see if [ann_mlp] is something Davide or anyone else still wants to maintain as part of the [ann] library. I also see that Iohannes and Georg Holzmann put in work on [ann], and I'm wondering about its status for the future. I don't think I'll be taking on updating the other objects in [ann], so one option would be for me to put my updated version of Davide's [ann_mlp] out in the world on its own for now. I've been calling it [fann] in my own use since it's a direct interface for FANN functions. Any thoughts on this? Is there another neural net package for Pd that I'm totally ignorant of? A more current version of [ann] using FANN 2.0 that I just didn't come across in my searches?

recursive searching with [text search]
by Liam Goodacre 25 Jul '18

25 Jul '18

People often ask about how to get multiple matches with [text search] (see here<https://forum.pdpatchrepo.info/topic/11504/multiple-search-results-in-text>). There are a few ways of doing it but none of them are very optimal, and it seems like something that would be much easier and more efficient if it were implemented with code. Would there be any traction for a new feature, say [text search -r], to allow for recursive searching?

"too many open files" error in 0.48.1
by Liam Goodacre 25 Jul '18

25 Jul '18

In 0.48.1 on Ubuntu, I'm getting a horrible scenario where PD refuses to open patches or create any more abstractions for me. I get an error message saying "too many open files". Granted I have a lot open, but this is a serious problem as it means I can't access all of my old performances. They worked fine in 0.47. Any ideas? Liam

cyclone not creating objects
by Csaba Láng 24 Jul '18

24 Jul '18

Dear list, i'm on raspi 3 with pd-0.47.1 with deken downloaded and added to the path cyclone. Loads at sturtup: Cyclone 0.3 beta 4; Release date: June 6th 2018 Loading the cyclone library did the following: A) Loaded the non alpha-numeric objects, which are: [!-], [!-~], [!/], [!/~], [!=~], [%~], [+=~], [<=~], [<~], [==~], [>=~] and [>~] B) Added /home/pi/cyclone to Pd's path so the other objects can be loaded too however none of the objects from this library is created even from the help files. Can someone tell me how to make it work? Best, Popesz
