Re: [PD] using joysticks to control PD

Actually, there is both a Linux and a Windows version (I think I even did the Windows version first!)

Re: [PD] C++ for pd

Hallo! > However the advantages in using flext for me as developer outweight > that, IMO. It is really well documented, very clean, has lots of > useful utility functions and I need to use flext anyways for Thomas' > cool externals, so flext is already installed. An other advantage is of course that you can use these externals also in MAX. To myself this is not important, because I do not use MAX, but the more people us a software the more bugs are recognized etc. So just an other thought: Would it be possible to rewrite Gem with flext (with not too much effort), so that Gem would also be useable in MAX (so maybe more people would like to make developments in Gem) ? And the next question: What about threads and flext. I know you can make threaded externals, but do they work relyable? (e.g. a threaded soundfiler (for non-devel-pd), threaded Gem (okay, would be easier without flext, but just in case), ...) > And I like libraries and code reuse in general, so why should there be > a different C++ interface for externals in Gem, PDcontainers, > readanysf~, creb, ...? of course ...

Re: [PD] problem with zexy external: matrix~(.pd_darwin)
by Koray Tahiroglu 04 Feb '05

Hello Everybody, I don't know if that is the same reason but when I try to run [matrix~] external in pd it gives load_object: Symbol "_matrix_tilde_setup" not found error, although matrix~.pd_darwin is in extra folder. anybody has a matrix~.pd_darwin compiled external for OSX that works perfectly fine? best.

matlab to pd (more)
by f.bardet＠voila.fr 04 Feb '05

04 Feb '05

Hi list, Thanks for your replies concerning matlab-to-pd matrix export. Some more questions : Can zexy lib process 3D matrices ? (I mean matrices with 3 indices, e.g. a 10x8x3 matrix) If yes, how is a 3D matrix described in zexy, and how can I export it from matlab ? If not, is there a pd lib which allows it ? Or a max lib ? thanks a lot. François Bardet 10 place Thomas F-63000 Clermont-Ferrand 0033 4 73 92 50 80 ------------------------------------------ Faites un voeu et puis Voila ! www.voila.fr

matlab to pd
by f.bardet＠voila.fr 04 Feb '05

04 Feb '05

Hi list, I'd like to import into pd a matrix processed in matlab. Is it easy ? I've been trying to : If I type "save mymatrix matrix" within a matlab script, it saves a file : matrix.m If I want to read this file within pd and the zexy external lib, I can send a read message but the file format seems to be different in zexy (the extension is .mtx), and pd doesn't accept it. What is the correct way to import a matrix ? thanks a lot.

convolution filter
by Roman Haefeli 04 Feb '05

04 Feb '05

hi i tried to create a convolution filter (if this is the correct expression for what i want), but i failed. i want to filter an audiosignal with an impulse response (e.g. of a room) or the transfer function of a loudspeaker. i read the docu about 'fft and pd' from marius schebella (http://www.parasitaere-kapazitaeten.net/Pd/fft_und_pd_en.htm) and i tried the patch from page 5. when i use an impulse response, where the first sample is 1 and the rest is 0, it works, which means that the output of the convolution filter is the same as the input. but when i change the position of the sample with value 1, i get bad glitches in the sound. the same, when i use any other impulse responses than the (dummy) one i described first. i also tried the patch from page 10 (convolution filter) which is the same as the pd-doc -> 4.fft-examples -> 08.convobros.pd. but this one seems to work more as a vocoder than like what i want. if somebody understands what i want and i am trying to explain --> hints or links are very welcome. also if somebody have already made a patch to generate reverberation with room impulse responses by convolution, i am very interested. cheers roman

readanysf~ and flext
by Ian Smith-Heisters 04 Feb '05

04 Feb '05

Saw someone talking about readanysf~ on the list today and thought I'd give it a shot. I hadn't realized it had resampling capabitilies. I got it to compile by some fancy mojo from http://iem.kug.ac.at/mailinglists/pd-list/2004-09/022353.html . Now when I open pd I get the following error: /usr/local/lib/pd/externs/readanysf~.pd_linux: /usr/local/lib/libflext.so: undefined symbol: garray_updatetime readanysf~: can't load library Does readanysf~ still only work with flext 0.4.5 as mentioned in the above thread? Or is there some other solution to this? Is there somewhere I can get flext 0.4.5? version junk: PD from CVS about 3 weeks old. About says 0.39 test 0 (?!?) flext 0.4.7 readanysf~ 0.13 chow, Ian -- Ian Smith-Heisters http://www.0x09.com

pool in CVS missing build files?
by B. Bogart 03 Feb '05

03 Feb '05

Hey Thomas, I'm trying to update my linux PD stuff and it seems the CVS folder for pool as of today does not have the build-* config-* and makefiles that readme.txt refers to. I recompiled and installed flext 0.5.0 as well, (I could not figure out how to tell it to go to /use/local/lib/pd/flext and not /usr/local/lib) I tried copying the old pool build files, but all kinds of things have changed, ie no libflext.a but: -rwxr-xr-x 1 root root 647995 2005-02-03 14:48 libflext-pd_d.so -rwxr-xr-x 1 root root 168032 2005-02-03 14:48 libflext-pd_s.a -rwxr-xr-x 1 root root 1094748 2005-02-03 14:48 libflext-pd_sd.a -rwxr-xr-x 1 root root 120564 2005-02-03 14:48 libflext-pd.so -rwxr-xr-x 1 root root 179800 2005-02-03 14:48 libflext-pd_t.a -rwxr-xr-x 1 root root 1151956 2005-02-03 14:48 libflext-pd_td.a So I could not get anything out of pool. Is it being updated for the new build system? Any pointers welcome! Thanks. B.

Re: [PD] fighting with route

hi thoralf if you create your messages with a "pack s s s f" object or with chains of "pp mov" and so on, then there will be a list output and it has to work with "route list". your patch is attached and corrected. tm
