Fwd: external help, please
by Alexandre Torres Porres 22 Aug '19

22 Aug '19

Hi folks, I need help on an external. I wanna perform a task on an array of signal inputs. It's a multichannel object, and I define the number of channels with an argument. Here's just the core of it, as an object named "mtx~", where I map the input to the output. And this is what happens. [image: Imagem inline 1] So you see I get a weird mirrored output, instead of something like "1 2 3 4 5 6". The perform method in the code is just static t_int *mtx_perform(t_int *w){ t_mtx *x = (t_mtx *)(w[1]); int nblock = (int)(w[2]); t_float **in_vectors = x->x_in_vectors; t_float **out_vectors = x->x_out_vectors; t_int i; for(i = 0; i < x->x_ch; i++){ t_float *in = in_vectors[i]; t_float *out = out_vectors[i]; t_int n = nblock; while(n--) *out++ = *in++; } return (w + 3); } What am I doing wrong? How should this go? See attached the help test example and code. Thanks

About inlet DSP prolog.
by Nicolas Danet 05 Aug '18

Hi, < https://github.com/pure-data/pure-data/blob/master/src/g_io.c#L210 > x->x_fill = x->x_endbuf - (x->x_hop - prologphase * re_parentvecsize); < g.io.c / line 210 > IMHO it does not properly shift the buffer in case of overlap (i.g. [block~ 512 4]) if stopping/restarting the DSP. x->x_fill = prologphase ? x->x_endbuf - (x->x_hop - prologphase * re_parentvecsize) : x->x_endbuf; The change above might solve the problem. I'm not 100 % sure. I'm currently testing the fix on Spaghettis < https://github.com/Spaghettis/Spaghettis/compare/dev >.

Re: [PD-dev] MARCH in Deken file name
by Dan Wilcox 30 Apr '18

When I think "march" I think of the string I pass to the compiler to explicitly get 32 or 64 bit. For clang on macOS, I say "x86_64" and for 32 bit I say "i386". It's fine if deken uses the different string, I was more trying to clarify my understanding. Ideally, I'd prefer if those string matched but I can also understand the underscore in "x86_64" is not ideal for the filename parsing. > On Apr 30, 2018, at 10:14 AM, pd-dev-request(a)lists.iem.at wrote: > >> >> When compiler on macOS, it's DEFINITELY x86_64.

amd64? When compiler on macOS, it's DEFINITELY x86_64. Isn't it the same in MinGW? > On Apr 29, 2018, at 12:00 PM, pd-dev-request(a)lists.iem.at wrote: > > On 04/28/2018 02:04 AM, Thomas Mayer wrote: >> Hi, >> >> what should the string for MARCH be in the deken file name for Intel >> compatible processors, the deken documentation is unclear here: >> >> - 64 bit: amd64 or x86_64? >> AFAIK both mean the same thing, but are used in different contexts, most >> Linux distros use amd64, while on Windows x64 (Visual Studio) and x86_64 >> (MinGW) are used, no idea about Mac. > > use "amd64" (although "x86_64" is allowed as well, the former is more > concise and used by the 'deken' cmdline utility) -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

MARCH in Deken file name
by Thomas Mayer 30 Apr '18

30 Apr '18

Hi, what should the string for MARCH be in the deken file name for Intel compatible processors, the deken documentation is unclear here: - 64 bit: amd64 or x86_64? AFAIK both mean the same thing, but are used in different contexts, most Linux distros use amd64, while on Windows x64 (Visual Studio) and x86_64 (MinGW) are used, no idea about Mac. - 32 bit: i386 or x86? Linux distros use i386, Windows x86, no idea about Mac. The examples use both 64 bit versions, inconsistent in the usage: https://github.com/pure-data/deken/blob/master/developer/README.md#filename… Thanks, Thomas -- "I'm a white male, age 18 to 49.

purest_json from Deken links to wrong libraries in Debian Stretch
by Roman Haefeli 28 Apr '18

28 Apr '18

Hey all Ubuntu 16.04 ships libjson-c2, Debian Stretch ships libjson-c3. The externals from purest_json from Deken link against libjson-c.so.2 and thus do not work in Debian Stretch. I only discovered that after I removed "obsolete" packages (packages that were installed from previous releases and were not removed during upgrade). Now I wonder: Is it possible as a Deken package maintainer to take care of this situation gracefully? Currently, you get packages from Deken that cannot work on some systems. Roman

soundfiler~ thread usage
by Dan Wilcox 17 Apr '18

17 Apr '18

I'm working on a project with 64 soundfiler~ objects which may or may not be used all at once. I've noticed in the debugger that the each object is using a thread after instantiation, even when not actually reading a file. Is this normal? If so, what's the reasoning? I'd think it would be better, resource-wise, to spin up a thread as needed. Does starting/joining a thread take too long and break determinacy? -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
