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.

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?

[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

I07 vocoder questions
by João Pais 30 Nov '11

30 Nov '11

Hi, This is a long mail. I was having a closer look at the I07 vocoder example, and wanted to ask a couple questions (some of them general, some a bit petty). They're divided into parts, in case someone doesn't want to answer everything: - in [pd read-windows], there's the [r $0-insamprate], is supposed to make "sample rate correction". Tracking from where this value comes, it leads to the sample loading subpatch, [pd insample] in the main window. There, the connection doesn't make sense to me: a) the right outlet of [unpack s f] never should give out something, as [openpanel] only delivers a symbol. b) so, the patch is hard coded to bang a 44100 to [s $0-insamprate] Since the whole patch can work with any sample rate, what is the function of the 44100? Does it assume that the loaded samples will be at 44.1KHz? So, a [wavinfo~] or similar object that says the samplerate of the loaded file would be better, right? And, if both loaded sample and patch have the same sample rate, this variable isn't really necessary, as it will give out 1, right? (which will be multiplied with the transposition, therefore changing nothing). So, resuming: does this connection recalculates the playback rate of the $0-sample table, assuming that the loaded sample is always at 44.1KHz, and the patch's sample rate can be variable? - - - - - - When pressing rewind, the location value goes to a small negative number. I gather that that's the half of msec for the window lenght. Why does a sample playback start there, instead of directly in 0? So that the front window starts on time, while the back window is delayed? (as explained in [pd read-windows]) - - - - - - Location display (main window, leftest) is in msec of the original sample, right? - - - - - - [s location-set] in [pd read-windows]: since this variable gets its value from [r see-loc] (which is banged~), it doesn't need to receive the value from [r location], right? - - - - - - [pd hann-window]: the variables window-msec and window-sec don't have receive counterparts. Probably a remain from an old patch? - - - - - - The no-detune bang should send 0 to transpo-set instead, right? - - - - - - As I never studied the fft part really closely, it still remains a mistery to me (although the function of each segment is described). Can someone point me to a place where to make sense of what's happening around? Or I should just go through all the tutorials until I get here? In case it interests to anyone, I've made a local version of the patch, with all variables and tables preceded with $0. Thanks again, JoÃ£o Pais

pix_set / pix_gain weirdness
by Matteo Sisti Sette 24 Nov '11

24 Nov '11

Hi, I get some strange behaviour with the attached patch which is basically: [gemhead] | | | [0 0 0 1 1 0 0 1 0 1 0 1 0 0 1 1 ( | | [pix_set] | | | \ // numbox attached to the second i.e. "common" inlet | | [pix_gain 1] | [pix_texture] | [rectangle] 1) When I send a new value to pix_gain's inlet, the output is not updated until I re-send the pixel color values to pix_set. 2) If I modify the pix_gain object and change its creation argument (which means the object is recreated), the pix_set seems to be reset as well: the rectangle resets to white, as if the pix_set objet was recreated. I have to re-send the pixel values to pix_set. After doing this, the pixel colors are as expected and the gain is applied correctly Why doesn't the pix_gain update its output when a new value of the gain is applied? Why does pix_set reset when I recreate the pix_gain object? Is all this expected behaviour and I am missing something? thanks m.
