0.43 should still be a test version
by Matteo Sisti Sette 16 Mar '12

16 Mar '12

Hi, I tested Pd Vanilla 0.43 for just a couple of days (this was some weeks ago) and I found enough show-stopper regressions that I had to immediately revert to version 0.42.5. Version 0.43 still isn't mature enough to be used for purposes other than testing it. It should not be considered as the recommended release for "everyday use"; and most important, until it is stable, bug fixes should be still released for version 0.42. I am especially worried about this last thing, as now for example I have to choose between a version that can't broadcast UDP packets on Linux (0.42.5) and a version where the GUI may stop responding at any time (0.43.0). Here are three bugs that make it unusable, all of them are regressions: bug 3298989: suddenly all the gui objects of a certain type (e.g. all sliders) stop responding bug 3273884: mouse wheel scrolling doesn't work (it scrolls all the way down and all the way up in a single "step") bug 3273848: editing an object box is painful. Depending on where exactly you click, you may be unable to reach the last character (even with the right arrow key); you have to click on it several times until you are lucky. Note that this is not meant as criticism to the great effort that has been done to write Pd 0.43; if I am criticizing anything at all it is the decision to release it as a stable release superseding 0.42.5. It's just too soon. I understand that the more people download and use it, the sooner these bugs can be detected and fixed and the sooner PD 0.43 will be stable. But if testing has to be encouraged, it must be done in a fair way. People who are not downloading Pd for the sake of testing it, and who need to get the most stable version, should be aware that 0.43 is _not_ the version they should download. Cheers, m.

IPA Vowel space analyzer
by Ludwig Maes 20 Feb '12

20 Feb '12

Hi, I was wondering how one would locate a vowel in the IPA vowel quadrangle using pd... Of course I would expect the corners of the vowel to depend on individual characteristics, but I dont know where to start. Anyone any ideas? Greetings, Ludwig

Re: [PD] Patching in fragments
by Jonathan Wilkes 16 Feb '12

16 Feb '12

Cool. When I use the keyboard shortcut "o", something seems different about [osc~] but I can't quite put my finger on it (see attached) :) Is there a way for the Tcl plugin to tell pd to use the key bindings only in editmode, and only when there isn't an active cursor in an object or message box? Also, can the Tcl plugin do things like dangle the object from the mouse pointer (without using the mouse message hack) and remove the object (without the cut message hack)? The behavior I'm after is this: 1) click the shortcut key and the object fragment dangles from the mouse(or it gets put on the canvas and is selected). 2) if the same key is pressed again, that object is removed and the next object fragment associated with that key dangles from the mouse (or gets put on the canvas, selected). 3) if a different shortcut key is pressed, the fragment gets put on the canvas (unselected) and the new fragment dangles from the mouse. I can get that behavior in my abstraction, but it messes with the clipboard data, plus it's dangerous because if you have part of your patch selected and you hit a shortcut key that part of the patch is lost (and you can't undo it!). -Jonathan --- On Fri, 1/8/10, Hans-Christoph Steiner <hans(a)at.or.at> wrote: > From: Hans-Christoph Steiner <hans(a)at.or.at> > Subject: Re: [PD] Patching in fragments > To: "Jonathan Wilkes" <jancsika(a)yahoo.com> > Cc: "PD List" <pd-list(a)iem.at> > Date: Friday, January 8, 2010, 6:48 AM > > Looks promising.

Re: [PD] IP address in windows?

PD-Launch videos + Miller Puckette's 20-lecture puredata video course??
by Epic Jefferson 05 Jan '12

05 Jan '12

Hi, I know the documentation of pd-Launch was quite iffy. But perhaps someone could let me know if it's been uploaded anywhere yet and, if so, where to find it. Also, I remember some usb sticks where for sale at some point with a supposed 20 lecture course on pd by Miller. Any way I can find that somewhere too? -- www.epicjefferson.com www.avmachinists.org Puerto Rico based Art Collective/ Non-Profit Org

CVs
by Josh Moore 07 Dec '11

07 Dec '11

I just got out of a long and heated argument with someone who claimed he was an EE and told me that digital synthesizers use CVs. I tried to explain to him that if they did, it would be ONLY a numerical conversion so he was wrong and he still insisted that digital synthesizers used CVs. Has anyone had this kind of experience?

OOP practices in Pure Data
by abel.jerome＠free.fr 07 Dec '11

07 Dec '11

Hi all, All along years of practice, I've developped with Pd as well as object oriented languages. Some methods and designs from OOP (object oriented programming) structure my patches, because I think they are very useful to clear thoughts and share patches. It is sometimes difficult to understand patches from other people, and more difficult when it is a complete project. Therefore I think it's quite "good" to link Pd programming with OOP. In the same idea, I like those resources : http://puredata.info/docs/tutorials/TipsAndTricks http://puredata.info/Members/bbogart/pddp http://puredata.info/docs/style-guide http://www.earcatching.com/pdconv/pdconv.pdf Sharing practices is also very useful to help eachother and beginners people structure their code (and their thoughts).

[OT] SSE/MMX tips?
by Bill Gribble 06 Dec '11

06 Dec '11

I am trying to code a simple operation using SSE2 instructions where possible. I have a feeling that what I want to do is just a matter of a couple of shufps and haddps instructions but I can't get it. Lazyweb please help! The operation is integration. I have a vector of 4 single floats (v4sf) and a carry-in float to start. For example CI F0 F1 F2 F3 5 1 0 10 -5 Yields F0 F1 F2 F3 6 6 16 11 So far iteration on plain floats seems to be the best I can come up with, but HADDPS is tantalizingly close to what I want to do. Any hints? Thanks, Bill Gribble

GEM's minimum requirements
by Nicola Pandini 03 Dec '11

03 Dec '11

Hi list! I'm trying to use an old laptop with a Celeron 2,6Ghz to playback some videos with a basic GEM chain (pix_film, pix_gain, pix_texture), but the performances are very poor. It's only due to the crappy celeron :-) ? What are the minimum requirements to play a video with GEM? Is there any optimization possible, like using videos encoded with a lighter video codec, or something like this? I'm using Debian with open video drivers (ATI dropped the support for the laptop's video card). Thanks! -- Nicola
