http get/post request in pd. how to?
by KHM t.hartmann 27 Nov '22

27 Nov '22

Hello List, is there a way to make http requests (get/post) in Pd? In max it can be done with the [dictionary] for composing the request header/body als JSON objects, then send it as a request with [maxurl]. Thanks for hints, Tobias __________________________________________ Dr. Tobias Hartmann Künstlerisch-Wissenschaftlicher Mitarbeiter / Assistant Professor exMedia - Sound Kunsthochschule für Medien Köln (KHM) Academy of Media Arts Cologne Peter-Welter-Platz 2 50676 Köln t.hartmann(a)khm.de +49 (0) 221 20189 228 www.khm.de www.exmedia.khm.de www.hartmanntobias.com

Thanks. There is also [m_scale] in rjlib <https://github.com/rjdj/rjlib> which includes dB and log non-linear scaling. I have not tried something like slide~ yet...

Distributing externals in notarized DMGs, was: http get/post request in pd. how to?
by Dan Wilcox 27 Nov '22

27 Nov '22

@Thomas: If you are interested, I have a helper makefile for signing & notarizing projects on macOS for distribution: https://github.com/zkmkarlsruhe/mac-dist-helper <https://github.com/zkmkarlsruhe/mac-dist-helper> There is an example pd external in a separate repo: https://github.com/zkmkarlsruhe/mac-dist-helper-examples <https://github.com/zkmkarlsruhe/mac-dist-helper-examples> If the project is distributed as a notarized DMG, then there won't be any security popups when loading the external. The only downside is you need a developer account for the process. I assume deken cannot currently extract DMGs but it might be good if we can offer that as an option, ie. zip the dmg into the .dek, then the dmg is unzipped, then mounted using the system's hdiutil. > On Nov 27, 2022, at 12:00 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 1 > Date: Sat, 26 Nov 2022 15:36:28 +0100 > From: KHM Mail <t.hartmann(a)khm.de <mailto:t.hartmann@khm.de>> > To: IOhannes m zm?lnig <zmoelnig(a)iem.at <mailto:zmoelnig@iem.at>> > Cc: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > Subject: Re: [PD] http get/post request in pd. how to? > Message-ID: <7A28C93B-343F-4D88-9E95-1F5EECC99326(a)khm.de <mailto:7A28C93B-343F-4D88-9E95-1F5EECC99326@khm.de>> > Content-Type: text/plain; charset="utf-8" > > thanks!

scale~ and slide~
by Orm Finnendahl 27 Nov '22

Hi List, as I couldn't find pd abstractions mimicking the behaviour of Max's slide~ and scale~ objects (with the separation of slide-up and slide-down values in slide~ and the enhanced exponential mapping of scale~) I rolled my own and attach it for your convenience and future reference in the ML archives.

Re: [PD] Another request to replace Pd's docs by a "better one" (was: some gui objects with grey background in help patches?)
by Dan Wilcox 26 Nov '22

26 Nov '22

If you read everything, you will go crazy. You have to filter and focus on what is actually helpful to your own goals, otherwise you will work on solving everyone else's problems for free, forever and still likely only receive bug reports. And some may wonder why not everyone is waiting on the forums, or on FB, or wherever to read every discussion... On a related note, I see the GUI help files all contain a representative example of the widget in question in the upper right corner... in default coloring. Personally, I feel that's good enough to relay the distinction between "white" and "grey." I do agree with IOhannes to avoid the blue text sine it mimics text selection coloring. > On Nov 26, 2022, at 1:40 AM, pd-list-request(a)lists.iem.at wrote: > > Nonetheless, I see this feedback today!

Another request to replace Pd's docs by a "better one" (was: some gui objects with grey background in help patches?)
by Alexandre Torres Porres 26 Nov '22

26 Nov '22

Hi. I assume nobody can take this discussion anymore, but the funniest thing happened and I just have to bring it up here and make some further considerations stressing things I already mentioned. I'm changing the thread subject a bit to tell you about the case. In the discord channel of "Plug Data" (a fork of Pd by Timothy Schoen) someone just requested PlugData to adopt L2ork's help files instead of Vanilla's! Didn't I say so? If you're only here in this mail list, you might miss this, but on facebook groups, discord channels, classes and whatnot, you get this ALL OF THE TIME and it just happened yet again today : ) For reference, here's the full message: *@Timothy Could you consider replacing the *-help.pd files with the updated help files found in L2Ork and PurrData? The default PD ones are filled with landmines, for example if you open bp~-help, now you have to fight with the dB box inside the little output~ graph. Just setting that dB to a correct value is painful, I think you might find if you try it. When you open bp~-help in L2Ork or PurrData the patcher is already locked and you can toggle DSP in 1 click in the upper right in a reliable location, and the docs are laid out nicer with iolet and argument descriptions. Granted some of the text has been shortened and edited down which irks me but overall the docs are more modern and have less legacy layout issues.* There are several issues in this request and I'm getting into the discussion. He's talking about the [output~] abstraction, which was introduced recently, along with references (which are already in PlugData by the way). So it's funny the complaint that L2ork has references (*iolet and argument descriptions*) cause so does Pd! It's not on the front but in a subpatch, and this is why I have an annoying "<= click" message to force people to notice it and open it (maybe I should use a pink color?). While we're at it, let me say I like the freedom of having a separate canvas for references, it gives us flexibility that is useful in a few cases. By the way, this is also how it works in the highly acclaimed and supposedly superior documentation of MAX (you gotta click on a "*?*" menu and then on a reference that opens in a separate window). Anyway, I wish the problem and feedback was "I hoped the reference was there right away as in L2ork and not in a subpatch". We could talk about that, and I could explain the problems, like how do you plan to deal with the help file of [expr] then? :) Btw, see how greatly this was managed in Purr Data... (or don't and take my word it's not superior). But this is up for discussion anyway... It's funny how it was mentioned that clicking on the number box of the [output~] abstraction, now present in [bp~]'s help file, is hard. I don't know how much harder it is than clicking on a slider and how easier it is to set the "right dB value" in a slider and what's really funny is that Purr Data's example for [bp~] doesn't really have a better option to raise volume as it has no usable example, nothing to output sound or listen to. While Vanilla's example is now much superior with an actual white noise being filtered so people can actually listen to it in action. Inlet description and argument is also clear in the help file example... Nonetheless, the perception is that this is all bad and how Vanilla's docs is "*filled with landmines*"... but no real examples are given to support how L2ork's is more "*modern and has less legacy layout issues*". I'll tell you one thing though, it doesn't seem to be the fact that [output~] now carries a bang whose background color is light grey and this stands out to the eye as the only thing in the patch that's not either pure black or pure white... the fact that l2ork's help file of float has a shiny light green bang for no good reason, while other bangs are white does not seem to pose a problem either. Some might think this matter is stupid and silly, but I see it has quite an important impact. It gives Vanilla an unfair bad reputation and rejection. As you can see, I'm really committed and fighting for this cause. I always heard how bad vanilla's docs were and it was a bit unfair as I could see many problems and mistakes in Extended/L2ork. Ok, they had references in most (but not all) 'vanilla' help files. I really wanted to revamp Vanilla's docs for this and now we clearly have much more quality information as a gazillion things were made, with countless revisions, changes, additions and fixes - plus we now have newly written from scratch references for ALL help files. So it is *really* unfair now. Nonetheless, I see this feedback today! I guess that well consolidated notions, unfair or not, are hard to challenge and it takes time. I busted my ass a lot in the last couple of years and it still doesn't seem enough :) I'm not giving up on this though... I'm glad and proud that Vanilla's documentation today is much more superior than any other fork. It would be maybe too much to expect that other forks just grab this documentation, but I hope that in the next few years this notion gets its deserved recognition. It's not that people aren't recognizing it's getting better. There are many positive feedbacks, but more things are yet to be done. Not sure yet what to do though. I don't think we need to mimic the looks of L2ork to pretend we're now using its supposedly more up to date and better revised content :) but I still see that minor user interface details are still taken into consideration to promote some sort of rejection and resistance. So, this is also a heads up to 'old school' people that didn't feel comfortable with some changes. As you can see, I'm still being somewhat conservative. I won't get too crazy or do things "in the dark", but I will study, I will think, I will ask, and I will probably include a bit more 'eye candy' things and other little details to make it more appealing aesthetically. I will also describe the reasoning behind further changes, saying how I based my decisions on what I gathered from feedback and discussions in other channels than this mail list and stuff... Please share your thoughts as well, of course. Also, this channel is always opened ==> https://github.com/pure-data/pddp/discussions cheers

ofelia 0.4 issues on linux (manjaro / endeavour / ubuntu studio 22.10) and development state
by padovani 25 Nov '22

25 Nov '22

Hello, I'm trying to make ofelia work on different linux systems (first I was trying in Manjaro and then I decided to run some virtual machines to see if the problem was localized). After downloading the 0.4 version via deken and running the scripts (arch ones for Manjaro 21.3.7 and Endeavour 3.43-1 and the Ubuntu ones for Ubuntu Studio 22.10), I could not instantiate the library. The initial issues I had seem to be related to the libGLEW and libboost_filesystem versions expected by ofelia. I have tried to solve this by creating symlinks with the expected filenames. sudo ln /usr/lib/libGLEW.so.2.2 /usr/lib/libGLEW.so.2.1 sudo ln /usr/lib/libboost_filesystem.so.1.80.0 /usr/lib/libboost_filesystem.so.1.71.0 Although these first issues are solved by doing this, I still get this error while trying the shape/polygon example: /home/padovani/pd-externals/ofelia/ofelia.pd_linux: /home/padovani/pd-externals/ofelia/ofelia.pd_linux: undefined symbol: _ZNK5boost10filesystem4path9extensionEv ofelia d $0-of ... couldn't create /home/padovani/pd-externals/ofelia/ofelia.pd_linux: /home/padovani/pd-externals/ofelia/ofelia.pd_linux: undefined symbol: _ZNK5boost10filesystem4path9extensionEv ofelia d $0-of ... couldn't create /home/padovani/pd-externals/ofelia/ofelia.pd_linux: /home/padovani/pd-externals/ofelia/ofelia.pd_linux: undefined symbol: _ZNK5boost10filesystem4path9extensionEv ofelia d $0-of ... couldn't create /home/padovani/pd-externals/ofelia/ofelia.pd_linux: /home/padovani/pd-externals/ofelia/ofelia.pd_linux: undefined symbol: _ZNK5boost10filesystem4path9extensionEv ofelia f; ofPushMatrix(); ofTranslate(ofGetWidth() * 0.2, ofGetHeight() * 0.5); ofRotateZDeg(ofGetFrameNum() * 0.5); polygon(0, 0, 82, 3); ofPopMatrix(); ; ofPushMatrix(); ofTranslate(ofGetWidth() * 0.5, ofGetHeight() * 0.5); ofRotateZDeg(ofGetFrameNum() * 1); polygon(0, 0, 80, 20); ofPopMatrix(); ; ofPushMatrix(); ofTranslate(ofGetWidth() * 0.8, ofGetHeight() * 0.5); ofRotateZDeg(ofGetFrameNum() * -1); polygon(0, 0, 70, 7); ofPopMatrix(); ... couldn't create /home/padovani/pd-externals/ofelia/ofelia.pd_linux: /home/padovani/pd-externals/ofelia/ofelia.pd_linux: undefined symbol: _ZNK5boost10filesystem4path9extensionEv ofelia f; ofBackground(102); ofFill(); function polygon(x, y, radius, npoints); local angle = OF_TWO_PI / npoints; ofBeginShape(); for i = 0, OF_TWO_PI, angle do; local sx = x + math.cos(i) * radius; local sy = y + math.sin(i) * radius; ofVertex(sx, sy); end; ofEndShape(true); end; ... couldn't create Any clues on how to solve this? BTW... is ofelia development currently abandoned or is it some very specific issue I am having here? Thanks in advance for any clues!

How to make a key control a sound
by Daniel Martin 24 Nov '22

24 Nov '22

Hello, My name is Daniel. I'm currently working on a patch for an investigation on the effects of harmonics on human health. I'm new in PD and would like to ask if the following two patches are possible:1) First I want the user (test participant) to be able to play a sample and choose a particular fundamental frequency for that sound. Then the user should be able through certain keys from the computer keyboard to filter that sound and let the fundamental plus a certain harmonic be heard. I would need to assign 15 different keys to the first 15 harmonics. So I suppose what I need is like a sampler that works like an instrument, I would use probably a cello sample. When I press a key, the sample should start to play and keep playing as long as I keep pressing the key. And it should stop when I release the key. 2) A second approach is to let the test participant sing a fundamental note and through pressing certain keys let him/her hear his/her voice filtered with a particular harmonic amplified. That should happen live, as he/she sings. It's a kind of artificial overtone singing. I'm currently following the tutorial of Kreidler (pd-tutorial.com) and it seems pretty complicated. I would really aprecciate your help, specially regarding how to make a key play a note or activate a filter. Best regards,Daniel Salva
