Preset management for Pd Vanilla
by Alexandre Torres Porres 13 Nov '23

13 Nov '23

Never really needed fancy preset management other than storing messages in a basic vanilla way. But I've seen people mention how Pd lacks a nice preset system. Not that I know what a fancy one actually needs since I never felt the demand. So I'm here to ask what people use in Pd Vanilla, be it a pure vanilla solution or an external. And also to ask what people miss. This is what I came up with as a pure vanilla abstraction, it's based on [text] and [savestate]. Here's the thing: https://drive.google.com/file/d/1A0ISEJo5F1E578WHM1doo1n2CJAthonU/view?usp=… In short, the preset abstraction takes messages and stores them. You can have many of these on your patch and use them to recall presets for any parameters. It takes any kind of messages. I'm making use of built-in sends and receives in the number boxes to make the patch cleaner. Just think that you can have separate control of each parameter having its own preset or group all of them together globally, or a group here and another there, whatever... Once you save the patch, the presets you saved get stored in the patch. As for my current idea for my ELSE library, I'm using an object similar to grab to take messages from [receive] objects. It's a development over this original vanilla abstraction. My first draft is this, I hope that sharing the screenshot give you a nice idea.

soundtouch~ for Pd Vanilla
by Alexandre Torres Porres 31 Oct '23

31 Oct '23

Hi folks, I'm on a vibe of uploading missing libraries and objects for Pd Vanilla on deken. On the list I have FFTease, Lyonpotpourri, CICM-Tools and more stuff that I'm looking into, just so you know... Now, I see there's an old soundtouch~ external here: http://www.katjaas.nl/pitchshift/soundtouch~.html - it's "version 0.9" by Katja Vetter. It was developed with SoundTouch version 1.6 and Pure Data version 0.42. I tested on Pd 0.51-4 32 bits on mac and it works fine. There are binaries for download on the link above, but not for 64 bits. I wonder if anyone wants to help me build these with pd-lib-builder and all. Now, the ceammc librarym (and Pd-ceammc distribution) has a soundtouch~ external too. It's the same name, but not the same external, this one is marked as "version 0.1". So we do already have "a" soundtouch~ for vanilla, but I wanted to also get katja's external up there. So I just uploaded the download from that page here https://github.com/porres/pd-soundtouch - It's just the download as it is and we need to change to hopefully use pd-lib-builder, which would make things easier. I did try that and it didn't work. So, anyone onboard with this? cheers

cannot find ggee external - I need [shell] or [command]
by mick mengucci 01 Sep '23

01 Sep '23

Hi list I need the [shell] object to trigger python codes from within Pure Data. I am trying on raspberry os, with a raspberry 4, Pd version 0.51.4. But it would be usefull also for pc as in schools I rarely meet linux users, unfortunately. I checked here https://puredata.info/docs/ListOfPdExternals/ where it says that flatspace or ggee or flatspace/ggee would have this object. But in Dekken (Find externals) I do not get any result. I also saw that Alexandros suggests [command] but which external do I need installed? -- MKSTURA.EU MISTURAPURA.NET <http://WWW.MISTURAPURA.NET> mickmengucci.bandcamp.com facebook.com/mickmengucci3 facebook.com/Labio.pt pure mixture vibration since 1995

Prototype for adding an object browser into Pd Vanilla's core
by Alexandre Torres Porres 05 Jul '23

05 Jul '23

Hi everyone, I made a prototype of a GUI addition that I would really like to have included in the Pd-Vanilla distribution. I don't don;t think it is worth or plan to provide it as a tcl/tk plugin and I'll get to that soon. Nonetheless, as a prototype for anyone to easily test, I did upload object-browser-test-plugin to deken and you can get it. You can also check https://github.com/porres/object-browser-test-plugin And what does it do? When you right click anywhere on a patch canvas you can go to 'add object' which gives you a menu of all Pd objects that you can then choose from and it'll add the element exactly where you right clicked at. This is possible regardless if you're in edit or run mode. See screenshot below. [image: Screen Shot 2023-03-10 at 02.32.26.png] I got the idea and basis from Pd-ceammc, by the way. But PlugData is also working on something similar, why not offer an official one upstream? As someone who uses Pd to teach newbies all the time, I believe something like this would help them much more in the learning curve. The general consensus from users when I mentioned this on the facebook group (and other places) was quite positive. I understand though that there might be concerns in maintaining this and keeping the core light. Well, if it gets included, I plan to take care of it and do things like insert a new object whenever it comes up as long as I live. I am relatively young and don't have plans to die soon. This would be part of my documentation engagement. And once it is in, I guess the load won't be relevant. I think this is problematic to keep as a plugin as it'll mostly be missed by users. Another problem is that I think it is hard to maintain this out of the core and I say this because while my plugin works now, it is already broken for the current master on github, so it won't work on the next update. It really makes sense to keep this in the core then. By the way, it already includes the not yet released [snake~ in]/[snake~ out] objects, and when I wanted to test this with the latest current version is when I found out it breaks. But it works up to 0.53-2 (at least with its test version that you can find). And yes, I added options for objects that have a function defined by the 1st argument (such as [array random]), [snake~ in/out], ect). I also added options to add GUIs, message boxes, list box, etc... Is anyone bummed out and would have some sort of issue with this functionality? Worst case scenario I guess would be to allow some configuration in preferences to disable this, but I can't see this as an annoying addition. I think that even for me (someone who revised and wrote references for ALL objects) this is useful, as even I can forget the name of an object sometimes... what are your thoughts? cheers

example needed: rfft~ into magnitudes AND phases AND back
by Peter P. 03 Jun '23

03 Jun '23

Hi list, trying to work on phase angles of spectra I am looking for an easy example with actual Pd objects how to convert a [rfft~] output from real and imaginary to magnitudes and phases, eventually unwrap phases if required, and then convert magnitudes and phases back to a cartesian for [rifft~]. I know about the Dudas/Lippe pvoc tutorials for MaxMSP but can not find much in Pd's documentation. Perhaps I am missing something? Thanks for any pointers! best, Peter

update on Gem for Apple Silicon?
by John Harrison 03 Jun '23

03 Jun '23

We're approaching 3 years now since Apple released the M1 and there's no Gem available for distribution on Apple Silicon that I'm aware of. I'm not finding a lot of conversation about it on this list and when searching in the Gem-dev list I found nothing. I tried compiling Gem for Apple Silicon myself and to my surprise it compiled and ran. There are some issues though. I didn't test thoroughly but quickly playing with some examples I saw artifacts when playing videos and general choppiness. Is Gem for Apple Silicon on anybody's radar? I'm up for being part of a team to get Gem on Apple Silicon if there's interest. -- John https://johnharrison.cc

Help with Gem on Fedora
by Francisco Medeiros 01 Jun '23

01 Jun '23

I need to play vídeo files with Gem on Nobara linux which is Fedora based but when compiling Gem I can only get film-support to use QuickTime. Does anyone know a way to install gmerin on Fedora? or What kind of video codecs work well with quicktime4linux? It complains about a bad magic number no matter what kind of file I try to open. Thanks, F. Medeiros

Linux/Manjaro: use system file manager insteado of tcl/tk one?
by padovani 31 May '23

31 May '23

Hi, is it possible to change the behaviour of PD to use the system file manager (Dolphin [https://pasteboard.co/3M8II8KNYusE.png] or Nautilus [ https://pasteboard.co/I4iBUqqcBAXH.png]) when opening / saving patches and other files instead of the painfull tk ( https://pasteboard.co/0YVTUU6uUV44.png) one? Have recently switched from mac and this specific PD idiosyncrasy is taking me much more time to patch. Thanks in advance!

If someone compiles vbap the way you described, which Mac > architectures will then be able to load the external? > > best, Peter The compiler, by default, builds for the native architecture of the build machine. If you need a multi-arch build, specify the archs on the command line using the "arch" pd-lib-builder Makefile variable: make arch="x86_64 arm64" Confirm the compiled archs via file: file vbap.pd_darwin which should spit out the compiled archs found. On my system I get: % file vbap.pd_darwin vbap.pd_darwin: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit bundle x86_64] [arm64:Mach-O 64-bit bundle arm64] vbap.pd_darwin (for architecture x86_64): Mach-O 64-bit bundle x86_64 vbap.pd_darwin (for architecture arm64): Mach-O 64-bit bundle arm64 You can zip the folder and send it someone else, however a Getkeeper check will be triggered since the dynamic libs are not signed or notarized. It should mean the person running Pd will be asked if they will allow to load the lib. If I remember correctly, if you allow once, then it will run ok afterwards. Note: the available architectures depend on which macOS version & command line tools/Xcode combination the build system has. Any newer macOS 10.15+ will support both x86_64 (Intel 64-bit) and arm64 (Apple Silicon). Also, the build system does *not* need the full Xcode installed to build a simple C + Makefile project. The command line tools installed via "Xcode-select --install" will suffice. I should probably add the above info the pd-lib-builder tips & tricks markdown... -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
