data structure array not mouse editable
by patko 20 Feb '11

20 Feb '11

Hello, I'd like to draw array with data structures that is not mouse editable, and I've seen it's possible to do such thing by drawing array of array. >From what I've understood by reading the archives, this is not really an intended behavior. So I'd like to know if this behavior will stay like this, or if there is a plot option to disable mouse editing. -- Patrice Colet

Regarding ambiguity, I'd say a good rule of thumb is that one should be able to draw the patch on a sheet of paper without introducing any ambiguity. So things like inlet tool tips and cord shaking don't resolve ambiguity in the visual representation of the patch, though they may be useful in other ways.

If you never depend on connection order (which you sholdn't because, as we've discussed, it is visually ambiguous), then how exactly would that help you debug? -Jonathan

Compiling vanilla 0.42-5 on OS X 10.6
by Elliott Slaughter 19 Feb '11

19 Feb '11

Hi, I'm trying to compile vanilla Pd 0.42-5 from source on Mac OS X 10.6, and after doing a ./configure and make got a lot of warnings followed by: lipo: can't figure out the architecture type of: /var/folders/pI/pIcjee4GEbOGlylnzdAsZ++++TI/-Tmp-//ccLn5z7A.out Am I missing something? The instructions didn't make this sound hard. I'm using Xcode 3.2.5 (GCC 4.2.1). Thanks in advance. -- Elliott Slaughter "Don't worry about what anybody else is going to do.

Pd-extended 0.42.5 Lucid - Audio Settings / Delay - not working!
by Ingo Scherzinger 19 Feb '11

19 Feb '11

Hi, I just wanted to change the delay in the audio settings for a higher latency to avoid glitches and dropouts in my current patch. Unfortunately there is no effect when I change the delay time. Even setting it to 100 or 300 ms results in 0 delay (+ the usual os delay, of course)! I am using the first release version of 0.42.5 on Lucid with oss. Does anybody know if there was a bug about the audio settings in that version? Everything is working as expected on windows xp with (probably) the same version as well as with the 0.43 version on windows. (I havn't tested 0.43 on Linux, yet) Ingo

Re: [PD] Pd-extended 0.42.5 Lucid - Audio Settings / Delay - notworking!

No Bernardo, I get the same or even better latencies. Down to 5-6 ms (pd audio sttings display) with a very complex patch. Alsa is giving me more problems like digital A/D/A sync errors. As far as I know alsa is using oss anyway. Not sure if I'm wrong here. Anyway, I just figured out what the problem was. I had a "-blocksize 64" flag set when starting the patch. Changing this blocksize to a higher value like 512 did the trick. Now higher delay settings have an effect. Seems a bit strange to me as the actual blocksize doesn't seem to change but the maximum buffer size is increasing. It also like it's giving me a slightly lower cpu consumption (10-20%). I'll have to try different values in order to see what seems to be the best setting.

externals tutorial: link error
by Elliott Slaughter 19 Feb '11

19 Feb '11

I'm getting a link error when following the counter tutorial from the following page: http://pdstatic.iem.at/externals-HOWTO/node4.html 2>counter.obj : error LNK2001: unresolved external symbol _s_float 2>C:\Users\Elliott\...\externals\build\Debug\counter.dll : fatal error LNK1120: 1 unresolved externals I got the first (hello world) example to build and link and run, so I'm not sure what I'm doing wrong here. I am definitely linking against pd.lib, because if I stop linking against it, I get about 8 link errors instead of 1. My code is identical to the example except for an added extern "C" and __declspec(dllexport) to get the counter_setup function to have the correct visibility. I am building with MS Visual Studio 2010 and the Pd 0.42.5 from http://www.crca.ucsd.edu/~msp/software.html . I would be happy to provide more details on my code and build system if that would be helpful. Thanks in advance. -- Elliott Slaughter "Don't worry about what anybody else is going to do.
