Hello everyone, Does the ">~" still exist? From what I gather it was in Pd-extended, but I can't find which library it comes from. Does anyone know? Thanks! - martin

Gem: Looking for suggestions for camera / capture setup
by Max 10 Mar '21

10 Mar '21

Hi List, what's a good setup for a decent framerate (50, 60 fps or even higher?) HD live capture from Gem? Is it even possible? A related problem is that ideally I would like to have Gems framerate be driven by the capturing, so that I'm sure not to have missed frames or have captured the same frame twice. Is there a solution to that? m.

messy situations: writesf~ feature request
by info＠hansroels.be 09 Mar '21

09 Mar '21

Hello, I think it's a problem that in 'messy' situations you don't have feedback from writesf~ to know/see that the recording is happening. With 'messy' I mean situations where you aren't fully concentrated on recording, for example: simultaneously performing on stage and making a multichannel recording, moderating a meeting and at the same time recording it. I have noticed that after some of these messy situations, I didn't have a recording or a channel was missing/silent. I tested writesf~ and here are some observations: A) if you send a [stop( message to writesf~ after [open( the recording doesn't start but there is no error message (in the main Pd window); next, if you send [start( there is an error message and no recording. B) if you send [start( -and thus start the recording-, next switch off the DSP, switch it on again, the recording automatically continues (from the moment the DSP has been switched on again). No error message is printed. C) if during a recording, the DSP is switched off and the patch -with writesf~- is also closed, the recording stops of course but no panic: the recorded file is OK and available to be read. No error message is printed. D) If you send a second [start( message during the recording, an error message is printed but in fact the recording continues without any problems. E) If you send [open(, next [start( when the DSP is off, the recording doesn't start but no error message is printed. Next, when you switch on the DSP, the recording automatically starts. F) If the signal connection going to writesf~ is broken, the recording starts without an error message, but the recorded file will be useless: it only has zeroes. G) If no signal at all is connected to writesf~ it still records (zeroes) if the DSP is on. No error message or warning is printed. B) & C) & E) are great ! I think D) & A) are a bit strange and in situation F) & G) it would be better that the recording wouldn't start or at least give some kind of error or warning message). So here is my feature request: 1. writesf~ has an output which displays if the recording is happening. 2. writesf~ doesn't record or outputs a 'no input' warning message when the (upstream) signal leading to writesf~ is broken or missing Hans

Hi, I've installed deken-plugin from deken on pd 0.51.4 - Windows 10 I get this error on pd console: ----------- UNHANDLED ERROR: char map list unbalanced while executing "string map "@PD_PATH@ $::sys_libdir" $path" (procedure "::deken::utilities::substpath" line 2) invoked from within "::deken::utilities::substpath $p " (procedure "::deken::utilities::get_writabledir" line 3) invoked from within "::deken::utilities::get_writabledir [list $::deken::installpath ] " (procedure "::deken::find_installpath" line 5) invoked from within "::deken::find_installpath" (procedure "::deken::initialize" line 10) invoked from within "::deken::initialize" invoked from within "if { [::deken::versioncheck 0.7.1] } { namespace eval ::deken:: { namespace export open_searchui variable winid variable platform var..."

samplerate mess when using JACK
by Roman Haefeli 06 Mar '21

06 Mar '21

Hi I would like to draw attention to this issue: https://github.com/pure-data/pure-data/issues/1283 It can have serious side effects, like wrong pitches, wrong timing, mismatch between audio streams sent over network (an issue which disguises itself as very jittery connection) and probably other problems. Since I mostly run Pd from command line, the problem never occurred to me, but I got reports from people who were trying to set samplerate through the dialog. Roman

Is it possible to access an abstraction without namecanvas?
by José de Abreu 05 Mar '21

05 Mar '21

Hello list, this is just a curiosity of mine When we create [pd test] we can send messages to pd-test, so if i send [;pd-test vis 1] it will show up. But if i create an abstraction "test", [; test vis 1] doesn't work, i am assuming that i need to put a namecanvas there, but, is it possible to access it without namecanvas? as a further question, a cloned abstraction also could be accessed without namecanvas? even just the first instance (there is nothing wrong for me in putting [namecanvas test$1] inside the clone, this is just a curiosity about how these auto created names works)

Is there a cost to wiggling GUI objects which aren't visible?
by William Huston 05 Mar '21

05 Mar '21

My 12 band Flanger/Panner thing was so awesome, I decided to convert it to [clone] to make it an N-Band thing. I'm getting close! ... But I am using a lot of wiggling GUI things inside the clone instances. Is this a problem? I have [hsl]s [vsl]s & blinking [bng]s, triggered by a global metro, sample interval (typically) 50 to 250 ms. *[metro 100] -> [s GlobalMetro]* placed at the top level ... all to help me see what is happening. I realize with [clone], there could be a big CPU cost here. *QUESTION:* *1: Is there a CPU cost to wiggling GUI objects * *in abstractions or subpatches * *which aren't visible?* *2: Does the rate of the metro matter? i.e.,* *Is there a higher CPU cost for many moving GUI objects * *updated at 10ms vs 250 ms?* Thanks, BH -- William Huston: WilliamAHuston(a)gmail.com Binghamton NY *Public Service Mapping / Videography / Research / Education / Safety Advocacy* Blog <http://WilliamAHuston.blogspot.com> -- Facebook <http://facebook.com/billhuston> -- Twitter <http://twitter.com/WilliamAHuston>-- Youtube <https://www.youtube.com/channel/UCGijK1amWOLglT3YeTyEBNQ?sub_congfirmation=1> * -- Podcast Blog <https://billhustonpodcast.blogspot.com/>* *Document collections*: VirtualPipelines <http://TinyURL.com/VirtualPipelines> -- BHDCSDimockArchive <http://bit.ly/BHDCSDimockArchive> *Please support my work! -- *TinyURL.com/DonateToBillHuston

[PD-announce] a barrel of fun: deken v0.7.1
by IOhannes m zmölnig 04 Mar '21

04 Mar '21

hi i'd like to announce the release of deken-v0.7.1 https://github.com/pure-data/deken/releases/v0.7.1 the GUI-plugin can be installed via deken. just go to "Help -> Find externals" and enter "deken-plugin" as the search string. this is the version i'd like to get into the next Pd release as the standard "find externals" implementation. so please test :-) what's new? deken-plugin ("Find externals" within Pd) ========================================= - decide whether you want to search of libraries, objects or both - select multiple packages (with right-click) and download/install them at once - install packages from files - library sorting has improved (newer libraries sort before older libraries, rather than reversed-alphabetically) - (optional) drag'n'drop package files onto the dialog to install them - callback to allow Pd to search for uncreatable objects (dekenception) - better support for packages with externals that don't do any number processing - optionally keep package files after downloading them - improve SHA256 verification handling - introduce @PD_PATH@ placeholder for the path the the current Pd-instance, so you can set the installation directory to @PD_PATH@/extra and installations won't interfere with each other. - (optional) SHA256 verification - fix close-window shortcut - lots more of fixes, bugs and laughs the features marked as "(optional)" require additional software to be installed (e.g. the "tcllib" (for SHA256 verification) resp. the "tkdnd" (for drag'n'drop; if you got the dropsuite plugin to work, then this will work as well) some of the features are not really user-visible yet, notably the one labelled "(dekenception)". but this is the deken-part of the recent click-broken-object-to-find-the-library demo i posted on the pd-list. deken cmdline (create and upload packages) ========================================== for those of you who develop libraries and publish them via deken, there's also an updated version of the `deken` cmdline utility. - much improved generation of object lists (using the DESCRIPTION of the object's help-patch) - new flag to override the package name - new flag to skip GPG-signing - settable output dir when creating packages - strip a leading "v" from the version to prevent accidental "vv1.2.3" versions - take dynamic libraries into account when calculating the architecture - new "systemfix" command - new "systeminfo" command (for bugreports) - new "uninstall" command to uninstall packages (or deken itself) - fix password input on MSYS2 - switch to hy-0.19/Python3 - binaries for macOS & Windows - Docker image (registry.git.iem.at/pd/deken:v0.7.1) for use in CI-systems - lots of fixes, wine and bugs _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

can a [clone] instance determine the total number of clones?
by William Huston 04 Mar '21

04 Mar '21

Is there a way for a clone instance to determine the total number of clones? Because often the behavior of a clone depends on its relative position within a chain of instances. "I am instance 12 of 100, therefore, I should behave like so...." I find myself passing in the number of total clones as a parameter. I would like to avoid this if possible.
