Dear all, BluePD is a new product of Blue Melon which has been released in the BlueSense series of modules. BluePD introduces Pure Data to the world of physical computing. With BluePD you can design your program visually using the popular Pure Data package. BluePD is equipped with a powerfull minicomputer which can execute your patch. This allows BluePD to physically control your setup without any attached computer. BluePD has a special port to connect multiple BlueSense modules. Each BlueSense module allows the user to add switches, analog inputs, digital outputs, servo motors etc. Please visit our site for more information: http://www.bluemelon.org/index.php/Main_page/BlueSense Regards, Dinne Bosman www.bluemelon.org ____________________________________________________________________________________ Looking for last minute shopping deals?

s pd-$0subpatch
by marius schebella 20 Feb '08

20 Feb '08

hi, I am working on dynamically created patches and just figured out (by accident) a nice thing. it seems the $0 in pd-$0subpatch gets substituted correctly by $0 even if it is not at the beginning of a symbol. that means you can have a subpatch [pd $0subpatch] and use [send pd-$0subpatch] to talk to it. makes life a little easier. marius.

Midifile Object
by saint 19 Feb '08

19 Feb '08

hi martin/all, sorry for buggin you about this again, but unfortunately i can't use your (or any) midi external for my purpose if i can't get this to work. the problem i'm having with midifile is this: i can't get midifile to read a .mid file that's in the same folder as the pd patch by referring to it by it's short name only i.e. without the full path c:/progra~1/etc/etc (which does work btw, thanks) is there anyway to get this... [read test.mid( | [midifile] ...to work?! (where the midi file and pd patch are in the same folder of course) basically i need to copy multiple instances of the patch and run it from lots of different folders each referring to different midi files again thanks a million in advance you've been more than helpful so far! ----- Original Message ---- From: Martin Peach <martin.peach(a)sympatico.ca> To: saintidle(a)yahoo.com; pd-list(a)iem.at Sent: Tuesday, 12 February, 2008 8:53:59 PM Subject: Re: [PD] Phasor Driven Midi File Playback? The latest versions are part of pd-extended in http://autobuild.puredata.info/auto-build/ but the last functional WinXp version is in late 2007. The spaces in path names cause trouble throughout pd and other "cross-platform" programs, the only workaround I know of is to rename your directories without spaces. I usually use underscores instead. "Program Files" always causes trouble. Sometimes you can access it using something like C:\PROGRA~1 (the short DOS name) This works on my system: [read C:/PROGRA~1/pd/doc/5.reference/textfile.txt( but [C:/PROGRA~1/pd/doc/5.reference/textfile.txt( | [read $1( does not work.

Re: [PD] the behaviour of [list length] has changed!!
by Matteo Sisti Sette 19 Feb '08

19 Feb '08

Frank wrote >> 2 - the documentation (help patch) is unchanged, and there is no >> ambiguity in it: it describes the old behaviour. > > You may have a different help patch than I: Mine doesn't describe this > issue at all. You have to look inside the [pd length] subpatch. It says: "The "list length" object outputs the number of arguments in a list or other message." Though it is not very very explicit, it does describe the old behaviour strictly speaking. I am not good at writing help-prose, otherwise I would post a corrected version. A possibility may be something like: "The 'list length' object outputs the number of items in a list. Non-list messages are automatically converted to list before computation". But I'm sure anyone can come up with something better. Btw sorry again for posting the message without searching the archive. bye m.

zexy help (asked zexy but it crashes PD)
by matteo sisti sette 19 Feb '08

19 Feb '08

Hi, I have just installed zexy because I need to truncate a symbol and I thought I'd try that with symbol2list and list2symbol. At first I thought that [symbol2list] and [list2symbol] would be available as objects but it isn't so. So I thought it may be [zexy symbol2list]... I created a [zexy] object which appears with only one inlet and no outlet, and a message on the PD output window appears saying "Send me a 'help' message". So I created a [help( message box, I connected it to the [zexy] object and sent it... wasn't it what it meant? This crashes PD. Right-clicking on the [zexy] object and selecting "help" doesn't work ("sorry, couldn't find help patch for "zexy.pd"). I have PD-Vanilla (now not so vanilla any more) on Windows XP. I followed the installation instructions and ran z_install.bat: it copied zexy.dll to the "extra" directory, the help patches to extra/help-zexy, and the abstractions (*.pd) directly into the extra directory. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

is this a bug?
by Matteo Sisti Sette 19 Feb '08

19 Feb '08

Hi, In the attached patch, I try to dynamically create an object (in the example an [s]) by sending a message to the canvas, and I want this object to have a creation argument $1-foo1 or $1-foo2, etc... That is, the creation argument of the object must contain a "$1" that must not be evaluated when creating the object, plus some fixed part and a number that must be evaluated when creating the object. Then I create at the same time a second object that has a creation argument that is just a clean $1 (not evaluated at creation time). Look at the attached patch and click on the [3( message box. Can anyone tell why the object on the left is created with creation argument \$1-foo3 rather than $1-foo3, while the object on the right is created with creation argument $1 (not \$1)? Shouldn't the two behave the same way? (in my opinion like the one on the right) If I then save the patch and look at it as a text file, I see that the object on the left is saved as \\\$1-foo3 with four slashes!!! If I then open the patch I saved, it looks fine ([s $1-foo3] with no slash) and if I re-save it the 3 extra slashes are eliminated. I have often come across similar situations in which either the dollar argument is evaluated or too many slashes are added, but you can't obtain an unevaluated dollar argument with no slashes (i.e. internally only one slash). If this is by design, I really don't understand it.

nqpoly4 mystery
by Andy Farnell 19 Feb '08

19 Feb '08

Does anybody really understand nqpoly4~ ? :) I don't use it very often , but when I do it needs several goats sacrificing to make it work. Maybe I forgot to appease the right god or something this time, but I just keep getting $1 $2 $3 $4 $5 $6 $7 $8 $8 can't create According to the helpfile abstractions need to obey certain requirements. Does anyone know what these 'certain requirements" are, exactly..? Has anyone every written a tutorial on it? The helpfile contains some promising looking examples, but honestly after all the time I've used Pd I still don't understand this voodoo object. cheers for any help Andy -- Use the source

One which remains constant and provides the feedback, and another one that you vary the length of. ([vd~] might be a better option) Another way could be to use a table instead of a delay buffer. Tim

[output] some old Pd+GridFlow videos

Hi all, I uploaded some old videos (from the last 3 years or so) made with Pd and GridFlow (except "B15", which used PostScript): http://www.blurty.com/users/claudiusmaximus/day/2008/02/17#434 Hope they're of interest, Claude -- http://claudiusmaximus.goto10.org
