Pd 0.37.4 app test release for MacOS X
by Hans-Christoph Steiner 15 Sep '04

15 Sep '04

So I have gotten the rough version of the new MacOS X package working. Keep in mind that this is a test version, but it should be usable. The aim is to have everything needed to run Pd in a Pd.app, so that you can just drag-n-drop to install. Plus, the long term goal is to make Pd behave like a normal MacOS X app, but there needs to be some biggish changes for that to happen. http://at.or.at/hans/pd/installers/ Lots of stuff has been added, including: iemlib pmpd toxy There is some stuff I would like to add, but need some help from the respective developers: flext (compile straight from CVS on MacOS X) Gem (compile from the command line) pdp (statically link for all deps) gridflow (help compiling) So this Pd.app is all set for the AppMain.tcl way of building a Tcl/Tk MacOS X app. In order for that to work, Wish Shell has to launch Pd rather than Pd launching Wish Shell. I started playing around with trying to get that working but didn't get that far. Anyone else working on this or have some pointers? .hc http://at.or.at/hans/

Pure data Process on electronic stand alone board ?
by abel.jerome＠free.fr 15 Sep '04

15 Sep '04

hello List! A dummy question. Is it possible to transport a patch pd on a light electronic system, which is powered by a simple batterie? Because, I think about interaction in the city, with sensors and speakers. the problem is the computer between them. Not very simple to leave a computer (or a computer in a box) in a street. Is there a way to export to another protected machine for outdoor? Ps: I can't go to the pd convention (money, money) so I couldn't see the list in real life, snif snif. so, have a big fun meeting. Shoot the evidence, and stand up pure data in the real world ! JR

GUI question
by Anton Woldhek 14 Sep '04

14 Sep '04

I was wondering why PD has a vertical data flow. Just looking at the resolution of my screen: 1024 by 768. I got more space horizontally. Obviously the horizontal screen came from Max. Just curious if there are good reasons to choose a horitonal way of structuring. Cheers Anton ps I failed to search the archives prior to this post, pls ignore/flame/etc. me if this has allready been beaten to death.

VST
by Thomas Ouellet Fredericks 14 Sep '04

14 Sep '04

Up to now, all my VST plugins work great with vst~ for PD. Thanks a lot! Here are a few observations: 1) When you load a dll, eventhought it is not a VST it still outputs the invalid dll name when you click getplug. I think GETPLUG should only output valide vst plugin names as a means of checking if your plugin is correctly loaded. 2) I think Vst~ is treated as a graphical object meaning in warps the window size when graph on parent is activated. 3) Sometimes, it can not get the names of the parameters eventhought they are detected and function. examples : crazy ivan from http://www.smartelectronix.com/~bram/ and a bunch of mda vsts from http://www.mda-vst.com/ R.A) Is there a way to send a midi Sync signal, maybe there is a way to do it with midi messages, I just do not know how. R.B)Also, could vst~ output midi messages? The two previous requests would open up the world of vst sequencers and that would be great. Happy to be a vst~ user tom

toxy quirk
by cdr 14 Sep '04

14 Sep '04

>can anyone get dropfile.pd to corectly open with .38test4? >on windows? on my pd it opens blank (if i have -lib toxy in my .bat). i'm not sure that's specific to 0.38. however i would always recommend building toxy to your pd version, rather than use binaries( the makefile in externals/miXed/ will build in GCC on windows, or linux..or osx...) since a minor tweak in any of the g_ files could break everything...(mathieu has seemed interested in pure-Tk GUI objects so i would hope or suspect the process is integrated one day..) so i noticed if you open drop*.pd first, pd freezes, on this: image create bitmap ::toxy::img::empty -data {} proc ::toxy::doreply {target vname vndx op} { pd [concat $target _rp $::toxy::reply \;] unset ::toxy::reply } pdtk_canvas_new .x9f5850 505 131 +471+279 0 wm title .x9f5850 {dropfile.pd - C:/samples/_p/pd} set menu_windowlist {{dropfile.pd .x9f5850} } pdtk_fixwindowmenu however, if you open another toxy-using patch first, or, if you add -lib "widget;zexy" it should work on launch....

dynamic subpatch / canvas naming
by Tim Blechmann 14 Sep '04

14 Sep '04

hi all, i've got a problem with message based patch generation ... i'm using an abstraction with a subpatch, i want to create objects inside this subpatch. therefor i named the subpatch $0-something ... but when i do something like: |ii $0| | |sprintf pd-%d-something| | |; $1 obj 100 100 catch~ test( it returns: "error: $1: not enough arguments supplied" ... i _can_ create the object when putting a namecanvas $0-something into the subpatch, but since it's declared obsolete, i suppose, there is another way ... cheers ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk After one look at this planet any visitor from outer space would say "I want to see the manager."

Re: [PD-dev] small gizmos
by Tom Schouten 14 Sep '04

hi all, i did some more research on the cross-compilation thing and realized it is better to do this in pf. it has all the required machinery to make it work, can run standalone and can be hosted by pd. mole is currently too much of a liability to use as a basis for building the pd<->microcontroller thing. once the project works it should be possible to make it run in mole, which is much smaller because it doesn't have all this packet crap, until then i will concentrate on pf and send all remarks and comments to the pf-list. i've just sent a large email to the pf-list explaining the roadmap for hooking up virtual and real machines to pf. check: http://zwizwa.fartit.com/pipermail/pf-list as a test case i am porting the scaf virtual machine (simple cellular automaton forth) to pf. this works, not counting some small bugs. still, it's 'virtual' :) the only thing in the way at the moment to make this microcontroller thing work is the actual hardware and the bootstrap interpreter, which could be the 3-instruction forth. cheers tom

Data structures: Editing an array of arrays
by Frank Barknecht 14 Sep '04

14 Sep '04

Hi, now I'm playing around with the really mind-twisting parts of data structs: arrays of arrays. Attached patch uses a template, array_of_arrays, in the subpatch "pd paint-array". This has an array of arrays, but it seems impossible, to edit the elements of the interior arrays with the mouse. I can change them through a nested "element" filtering network as shown in the lower right corner of the patch, but they are impossible to reach with mouse editing. Is this intentional? Or a bug or maybe just a not finished part of the data structures subsystem? Ciao -- Frank Barknecht _ ______footils.org__

Wah Synth?
by chris tyrrell 14 Sep '04

14 Sep '04

hmmmm, seeing as there has been much talk of retro sounds I wanted to ask if anyone knew how to do or had done any good implementations of "wah synths" in pd, there apparently doesnt seem to be much information online about the process although i know it's a modulated filter but other than that not much at all. I assume that vcf~ has apart to play seeeing as how it can be modulated by an audio signal, but my past attempts were even worse than unsucessful. btw just so you know - the sound i'm looking for is those old over the top orchestral sounding wahs (think vangelis)... ===== ___________________________________________________________ALL-NEW Yahoo!
