[r pd-dsp-started] bangs upon object deletion?
by Peter P. 15 May '23

15 May '23

Hi list, I am using [r pd-dsp-started] to recalculate parameters. I am wondering why it outputs a bang when I create an (empty) object, and delete it again, either with the "Cut" menu item or the backspace key. Is this intentional and what would be a rationale? Thanks! P

Re: [PD] Number atom box limits overstepped
by Dan Wilcox 11 May '23

Howdy all, there is a changelog fr sorts included with the HTML docs. For Pd 0.46, it says: "Bug fixes to IEM GUIs: sliders and radio buttons pass floating-point numbers through without limiting them to the GUI's range or resolution. Also, the toggle no longer resets its "value" (the nonzero number it outputs) when receiving numbers in messages. Set compatibility to 0.45 or earlier to get the old behavior (using "pd compatibility" message or a startup flag)." This change brought the behavior of those GUIS to be in line with atoms and can be disabled, although it probably also disables other need things you might want. I can't find the commit for this, but I think it came from Miller, so maybe he can weight in. In any case, someone could always examine and port the Pd-L2ork approach to further discussion... > On May 11, 2023, at 4:54 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 2 > Date: Thu, 11 May 2023 08:30:01 -0400 > From: William Huston <williamahuston(a)gmail.com <mailto:williamahuston@gmail.com>> > To: Jo?o Pais <jmmmpais(a)gmail.com <mailto:jmmmpais@gmail.com>> > Cc: PD-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: Re: [PD] Number atom box limits overstepped > Message-ID: > <CA+HRq4mgC-YZT7PH=WAb5Rhj0OpT9gaeJi0MBH3bcViaFAawDA(a)mail.gmail.com <mailto:CA+HRq4mgC-YZT7PH=WAb5Rhj0OpT9gaeJi0MBH3bcViaFAawDA@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Joao, > > IIRC, some objects in pd-extended, like hsliders, > would always respect the limits whether dialed-in, or > when coming from an input. > > When i finally switched to vanilla, I noticed the same thing, > limits were not respected on the inputs, and a lot of my patches broke. > > I don't know whether the "sensible" behavior was ever in the > mainline branch, or only in -extended. > > It would be nice if we could request the sensible behavior in a PD patch. > I know it's always hard to change the behavior of an object w/o breaking > compatibility with older patches. > > But it would be nice to be able allow a checkbox that says > "enforce limits on inputs" (which is the sensible thing). > > BH -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Audio latency on linux
by Orm Finnendahl 11 May '23

11 May '23

Hi, for a project involving controlled and tuned feedback through the Audio Interface, we need very low latency (~ 9-10 ms roundtrip through the analog ins/outs) for it to work properly. We did some tests using OSX and linux based systems with different audio interfaces. On OSX I can get down to 16 ms with pd (44.1 kHz sr); using Max/MSP we can get below 10ms with a vector size of 32. On Linux the lowest I can get with pd is 29.33 ms with 48k samplerate (this is using alsa; jack is ~34 ms). jack_delay reports a 9.6 ms roundtrip delay through the analog outputs with a vector size of 64, so it is not the driver and in principle should be possible to get a lower latency in linux. I don't know if jack_delay is implemented with additional i/o buffers but even if pd adds an extra period in both directions that should be well below 30ms (64 samples are 1.33 ms at 48k). The added 20ms in comparison to jack_delay appear quite large to me. I even tried to compile pd with a lower blocksize (I changed DEFDACBLKSIZE in s_stuff.h and DEFSENDVS in d_global.c and can get down to a vectorsize of 32 without distortion at the audio interface), but that doesn't change the i/o latency at all. I didn't yet study the alsa/jack related code. Can anyone shed a light on this? It'd be much nicer to use pd for this than writing a dedicated app doing all the dsp (or using Max/MSP on OSX :-( -- Orm

change variables in struct?
by Forrest Curo 11 May '23

11 May '23

If I want to use a working example struct (from the datastructures help patches) I can readily change the values of the variables it uses. What about changing the names of those variables to something more meaningful for their use in a new structure? Will I need to construct the dreadful patch from scratch? Forrest Curo San Diego

Audio latency on linux
by Orm Finnendahl 10 May '23

10 May '23

Hi, I found it: The delay setting in the audio settings is the culprit: It was set at 25 ms and setting is to 0 ms will reduce the latency. Sorry for the noise... -- Orm _______________________________________________ Pd-list(a)lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list

pd~ set audio API on linux
by Orm Finnendahl 07 May '23

07 May '23

Hi, when using pd~ on linux and turning dsp on, the subprocess outputs "no audio API specified" to its pd window. It works receiving/sending audio from/to the parent process but in my special use case it'd be even nicer to input/output audio directly to the interface, which works as soon as I specify the audio API in the media prefs of the subprocess. Is it possible to specify the jack audio API somehow to the subprocess via message and/or params to pd~ to automate this? -- Orm

[menubutton] bug on W 11 machine
by oliver 03 May '23

03 May '23

Hi, just tried my (bad) luck on a new Windows 11 machine, and found the [menubutton] external of the TOF library to produce an (i guess) TK error. i have the latest PD (0.53.2) and the latest TOF version (0.4.2.) when i open the helppatch for [menubbutton] i can clear and fill the menu but as soon as I select something from it, i get a (red) error message in the console: menubutton0000021392f40970: no such object It seems to be Tk related, doesn't it ? For backtracking, i tried older versions of PD (on the W11 machine), and according to this, the error starts with version 0.52. With PD 0.51, [menubutton] works. I already files a bug report at Fred-Jan's github site, but just for the record: has anybody else experienced this ?

pd for android and abl_link~
by Orm Finnendahl 01 May '23

01 May '23

Hi, I'd like to build MobMuPlat with pdlib including the abl_link~ external. As far as I've understood, the original MobMuPlat code uses jcenter which is not active anymore and has been replaced by maven. It seems I need to add the maven repository to MobMuPlat's build scripts and somehow add the dependencies of abl_link~. Can anybody give information or point me to references how to accomplish this? Any help is appreciated! -- Orm
