Random number generation quest
by Enrique Erne 15 Nov '12

15 Nov '12

Hi List! Can a random number form 0 to 100 be generated with the following requirements: - No externals / Vanilla Pd only - DSP must be off - The patch is loaded with Pd through command line interface i.e. `pd -noprefs -nogui givemerandom.pd` - The output should not always be the same number Thanks for looking into it eni

Issue with [shell] and jack_connect/disconnect
by michael noble 13 Nov '12

13 Nov '12

hi all, I'm trying to use the [shell] object to automate JACK connections under Linux by calling jack_connect or jack_disconnect. While this works at first, it seems that the ultimate result is that pd spawns a number of processes that remain in the background, and very soon jack_connect simply stops responding. Has anyone experienced a similar issue, or can anyone suggest an alternative to [shell] for this purpose? thanks Michael

Kalimba: a Unity-Puredata binding released!
by Filippo Beck Peccoz 13 Nov '12

13 Nov '12

Hi list, I'm writing to let you know that Kalimba- a Puredata binding for Unity which also deploys on iOS and Android via libPD - is now on github. https://github.com/hagish/kalimba It's possible to locally create patches that receive data from Unity via TCP, and then build the project for mobile devices. We hope that anyone who's interested in using Unity together with PD will benefit from this!

For any thread that starts on the list, its best to keep it there, unless there is specific privacy concerns about the info in the email. Have you tried the other libs? I don't really use Jack, so I don't know this stuff so well. Also, I attached a new version of this library which should work on Pd older than 0.43 .hc

Extension Cord
by Jonathan Wilkes 12 Nov '12

12 Nov '12

Here's an idea for a useful gui object in case anyone else has seen a need: Problem: using [t a] or [pd] to extend a wire requires all incoming connections at the top of the object which makes it a crude substitution for segmented wires. Problem 2: segmented wires can end up making patches harder to read (though I don't necessarily agree) Problem 3: Often, esp. in help patches, you want to stack a bunch of msg boxes and connect them to the object like so: [method_1( [method_2( [method_3( [method_4( [object] But doing so obscures the visual diagram-- for example, [method_4( might erroneously have been left unconnected but the connection from [method_1( to [object] obscures this error. Solution: an "extension cord" object-- a line segment which, like a real extension cord, can take in connections all along the length of the line. It has a base at the bottom like a flagpole, with an outlet (or outlets). The line segment can be at any angle, and an object can connect to it anywhere along that line. Could also call it [flagpole], because in the message box example above the message "flags" would each have a small 45-degree wire connecting to the vertical line of [flagpole], and [flagpole] would have a single outlet at the base connecting to [object]. Thus, each 45-degree angled wire coming from each message box would show clearly that each box is connected, and there would be no ambiguity when viewing the patch as to the dataflow. Similarly, there are times when having the line of [flagpole] extending horizontally would make it easier to read a patch-- for example, if you have a lot of objects fanning into one object and end up with some wires of a very small angle that extend very close to another inlet (or cross through some other object). In such a situation it'd be much more elegant for each object to have a vertical connection to the extension cord. There might also be examples with an angled line, but vert/horiz might cover most situations. If you made it a one pixel border around a one pixel empty area for the pole and just made the base the name of the object in a box, it'd be visually distinct from wires. -Jonathan

I consider this something everyone should install now. The progress bar is a good enhancement. I wonder if it could somehow fit in to the GUI elements better somehow. Its fine how it is, but it seems a little out of place. Looks like there are some debug messages still in it, I get these when hovering: filename is 5.reference/all_about_arrays.pd basedir is /Applications/Pd-0.43.3-extended-20121008.app/Contents/Resources/doc filename is 5.reference/loop~-help.pd basedir is /Applications/Pd-0.43.3-extended-20121008.app/Contents/Resources/doc filename is 5.reference/all_about_arrays.pd filelist is 7751 filelist is 7751 .hc

Read individual words from a text file
by Antonio Roberts 12 Nov '12

12 Nov '12

Is there a way to read individual words from a text file? I've tried using [msgfile] and [textfile] but they can only read lines. I know that you can define a carriage return as a delimiter but is there a way to use a space as one? Thanks Antonio -- ============================ antonio(a)hellocatfood.com http://www.hellocatfood.com ============================

gcc export-dynamic error
by enrike 12 Nov '12

12 Nov '12

hi I am trying to compile pd extended on Ubuntu 12.04.1 32 bits. I am doing $ cd pure-data/packages/linux_make $ make install && make package First I get an error related to libjack (undefined reference to 'jack_port_register'). The list archives suggested to replace all references to "jack" by "jack2" in pd/src/configure. But now I am getting another error. This time gcc complains that unrecognized option '--export-dynamic' I have gcc 4.6.3-1ubuntu5. I have searched online but I dont see what could I do to solve this. any ideas? I have tried several times even starting from scratch deleting the whole folder and uncompressing again from the source tar.gz thanks enrike
