Simultaneous Computation
by Hannes Gräuler 09 Mar '09

09 Mar '09

Hi all, I'm new to Pd and I'm looking for some hints on implementing a DSP external. I want to implement an external which is capable of simultaneous calculation of 2 or more coupled instances of it. On the signal level, this is not possible, because the construction of the DSP tree forbids feedback loops. Another way to achieve simultaneous computation of coupled objects is the following: The coupled objects exchange their adresses via pointer messages. Now, when the signal of the first of the coupled objects is about to be computed it should also calculate all coupled objects and store each result in a buffer. When the DSP-perform on of the remaining objects is called, it simply copies the buffer its outlet. 1. While the above proposal feels like a hack to me, I'd like to ask if there is any other (smarter) way to enable simultaneous computations? 2. Given my proposal is worth to be tried, how would I get to know the "first of the coupled objects"? Is there a way to get the timestamp of the current DSP iteration, so that I can determine when to calculate all buffers? Thanks for reading, Hannes

pd~ loadbanged stdout hangs all pd processes
by Luke Iannini 09 Mar '09

09 Mar '09

Hallo, the attached repro hangs for me quite reliably : ) It's not always reproducible with just one [pd~] object, but two seem to do the trick every time. 42-4 of course. Best and sorry for the never-ending stream of crashes : ) Luke

Hi, I'm having trouble using [piperead~] on Ubuntu Linux. When I try the example from the help file, [pipewrite~] works ok, but [piperead~] crashes with a segfault. Anybody having similar trouble, or perhaps knows a solution? Thanks. einszueins.

I am the harbinger of crashing
by Luke Iannini 09 Mar '09

09 Mar '09

Sigh, here's another : ) This seems to have something to do with my MPD24 drum pads... whenever they're connected and I enter the MIDI preferences of Pd, I get the attached crash. It also occurs if they're configured (via .pdrc or the plist) as a default device. This started occurring on the newest builds of Pd-E as well as on Pd-0.42-4. It does not occur of my build of 0.40.3-extended. Anyone have any ideas? Best Luke

GSoC web project idea
by Hans-Christoph Steiner 09 Mar '09

09 Mar '09

I've had an idea for a long time for a web interface to the patches that people post to the pd-list. Basically, lots of really great code is posted to the Pd list, but it is not very easy to find it there. What if there was a searchable database of all patches posted to the pd list. You could search by object name to see all patches that use a certain object, then download it. I think that someone who was a decent web programmer could do this. Perhaps using something like Lucene, or really whatever. Is it worth a summer of code project? .hc ---------------------------------------------------------------------------- News is what people want to keep hidden and everything else is publicity. - Bill Moyers

GSC 09 : Organisation and Categorisation of Pd-Extended Externals
by João Pais 09 Mar '09

09 Mar '09

Hi, I just added a new category for the GSC09, Organisation and Categorisation of Pd-Extended Externals. This follows up recent discussions on the pd-dev list. It might not be eligible due to being more about restructuring already existing code than to make new code (which could be seen as "documentation"). But if doesn't go on, at least there was some effort to sketch the problem. The page is at http://puredata.info/dev/summer-of-code/OrganisationAndCategorisationOfPdEx…. About mentoring: neither me nor Enrique are up for the task of reorganising svn, as we don't know enough about what goes on below the user level of Pd - so we can't do much more than say "this or this would be nice". So our names are there due to interest in the project, but someone else should take care of the practical part of working the compilation material. If you think this person could be you, just put your name in. Best, JoÃ£o Pais -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp

shell .... again....
by mark edward grimm 09 Mar '09

09 Mar '09

i have been "trying" to use shell... works OK in linux but in osx it just crashes. i am just wondering if this thread went anywhere: http://lists.puredata.info/pipermail/pd-list/2009-01/067700.html i have it in a bunch of patches now and would love to use it more ... if it had more cross-compatibility (osx) because i tend to work with others + other os's. maybe i should just change to pdlua as frank suggested? or might shell someday get fixed? not sure what to do.... cheers mark

Each slider/etc. writes to a given index in the array and can easily be retrieved upon [loadbang]. Matt

Turn off Output~ automatically
by narbino＠ucsd.edu 08 Mar '09

08 Mar '09

I have multiple output~ in a patch that have 2 number boxes feeding to it, and when the numbers are moving the output~ turns on but when the numbers are not moving it continues to play the last sound played. How do i turn off the sound when the numbers are not moving without having to mute it myself?? Thank you. -Natalie
