butterworth/chebyshev/etc in biquad?
by Alexandre Torres Porres 16 Dec '14

16 Dec '14

Hello there. I've been studying filters and I was hoping someone could help me figure out some details about the filter objects in Pd. I'm mostly concerned about the filter types such as butterworth, chebyshev, bessel and eliptic. For instance, in [biquad~], can you get all of these 4 types of filter? I guess so... but if it's true, what are the differences in calculating the coefficients? Or perhaps someone could suggest me somewhere to learn about it. But like, about the filters described at "Cookbook formulae for audio EQ biquad filter coefficients" http://www.musicdsp.org/files/Audio-EQ-Cookbook.txt Do any of you know if they're Butterworth or what? And what about the filters in Pd, I was able to implement with biquad the following objetcs: [lop~], [hip~], [bp~], [lores~] and [reson~]. What types would they be? I'd also like to hear something about [vcf~]. Well, that's it... thanks ;)

Re: [PD] Cyclone help patches & issue list
by Dan Wilcox 16 Dec '14

If that does become a real scenario, I hope we can find a way to bring some of the Pd-extended UI changes into vanilla, such as the pixel perfect sizing across platforms, an option for the extended coloring (graytones) etc. Before anyone says “Pd-Lork has that”, I’m just wondering if it’s feasible to bring in some of the work Hans did after the gui cleanup which is already in vanilla. -------- Dan Wilcox @danomatika danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/> > On Dec 15, 2014, at 4:58 PM, pd-list-request(a)lists.iem.at wrote: > > From: Miller Puckette <msp(a)ucsd.edu <mailto:msp@ucsd.edu>> > Cc: "pd-list(a)mail.iem.at <mailto:pd-list@mail.iem.at>" <pd-list(a)mail.iem.at <mailto:pd-list@mail.iem.at>> > To: Alexandre Torres Porres <porres(a)gmail.com <mailto:porres@gmail.com>> > Date: December 15, 2014 at 4:46:22 PM EST > Subject: Re: [PD] Cyclone help patches & issue list > > > Just FYI….

Pd from git with -jack
by Roman Haefeli 16 Dec '14

16 Dec '14

Hey all Since a little while, Pd from git segfaults when I try to run it with -jack. I wanted to hunt down what's going on and tried to backtrace the issue with gdb, only to find out that there were no debug symbols compiled in. Google lead me to the following: $ CFLAGS="-g3 -O0" ./configure --enable-jack --disable-portaudio $ make -j3 $ sudo make install Interestingly, from then on Pd runs fine with -jack. My understanding of the gcc compiler (and probably building in general) is too limited to understand what is going on. In what way would those flags influence whether Pd segfaults or not with -jack? Is such behavior probably related to the version of gcc? Roman

data structures......
by i go bananas 15 Dec '14

15 Dec '14

something i have thought for a LONG time, and i guess a few others have too. They are just too hard to use. but they keep popping up in updates to pd, so it seems they are still being worked on. couldn't that work be put to better use? like, for instance, on a native PD state saving system???

Re: [PD] Cyclone suite initiative
by Fred Jan Kraan 13 Dec '14

Hi Ivica, Jonathan, Thanks for the response. @Ivica: > Why not simply use cyclone help patches provided in pd-l2ork that > already conform to the pddp standard? The pd-l2ork help patches with standard format indeed look much better than the 'free-style' pd-extended patches. That is why I use these as a base. But I do not copy them directly for several reasons: - the lack of curly lines in pd-extended make pd-l2ork formatted patches a little less clean than possible, - not all patches are correct, usually because the original had the problem, - the pd META information is incorrect (probably copied from an pd-core object), - to learn as much as possible of these objects, I try then to see if they work and how. This can lead to changes to the patch. Of course a mass copy would be a fast way to improve cyclone help, but with the long term goal in mind, I think this slow method could result in better help files. Later I will see how they look in pd-vanilla and pd-l2ork and make adjustments. @Jonathan: > But then Pd Vanilla aficionados might complain that to use cyclone they > would be forced to also install the pddp library for [pddplink] and > [helplink], because those objects do not ship with Pd Vanilla. > Otherwise they would end up with a lot of broken objects in those > help patches. > There seems to a 'rule' to make help-patches only dependent on vanilla objects, and this makes sense. But maybe we can use a rich help-patch to generate a vanilla-compliant one (see below). > All the little Pd libraries in Debian don't help this problem, because > not every GNU/Linux distribution uses apt. (Nor does OSX or Windows, > for that matter.) > The other main distribution tool is rpm. It might be interesting to know how much of the "Linux-market" uses either deb or rpm. For Windows and OSX, there is no ready made solution yet. But other software packages have a cross-platform package distribution system; the examples I know are perl (ActiveState) and cygwin. But is probably not trival to build or adapt something for Pd. > Also, I believe Hans emailed awhile back asking if I'd do the work > of removing the PDDP template boilerplate from the tutorial revisions > I did. He wanted me to leave only the [pd META] subpatch, because > that's evidently the only part Miller wanted to add to Vanilla. Making help-patches as much as possible is also one of the modifications I make to the pd-l2ork help-patches. So far I ignored the pddp code. But removing the line with "pddp/pddplink" seems to work and this can be scripted. But for pd environments that always have the complete set, it is a great feature to have links. Greetings, Fred Jan

Hello, is there a way to not spend hours about trying to find where an object come from when it couldn't create? An online database, something perennial...
