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

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

[PD-announce] Max pd~ object test compiled for M1 processors
by Miller Puckette via Pd-announce 13 Apr '23

13 Apr '23

To Pd announce - The pd~ Max object (which allows you to embed Pd patches in Max/MSP) is now available for the M1 architecture in a test version (0.55test1). You can get it at the usual spot: http://msp.ucsd.edu/software.html It _should_ be possible to run it in Max version 8 for either intel or "M1" (apple) architecture, using Pd compiled for either architecture - but I haven't tried out all the permutations yet. Bug reports are most welcome, either to Pd list or to me personally. cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

Re: [PD] Creating/editing patches on android?
by Dan Wilcox 07 Apr '23

07 Apr '23

Howdy Matevz, I don't believe so, although I must include the caveat tat I do not use Android, so perhaps there is something out there I am not aware of. Running patches via libpd in a mobile app is much easier than creating a live, graphical *editor* as with desktop Pd as: 1. the interaction metaphors are different 2. libpd does not have a way to tap into the core pd editing logic (yet) That being said (written?), it's certainly possible to create something that can automate writing a Pd file which can then be loaded by libpd, however, once things complicated enough, you basically end up duplicating most of the core logic with the detriment that you have to carefully try to keep it up to date with whatever version of pd / libpd you are using. In short: it's a lot of thankless work that is best *not* done without lots of interest, resources, and support. The closest thing I can think of is rooting the device to install a Linux distro so you can run *desktop* Pd, however I don't think this is where your question is focused. As the author of PdParty, which utilizes libpd on iOS, I made a clear decision early on to *not* tackle on-device editing, mainly for the reasons mentioned above. > On Feb 23, 2023, at 12:00 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 2 > Date: Thu, 23 Feb 2023 10:44:58 +0100 > From: Matevz Leskovsek <matevz.leskovsek(a)gmail.com <mailto:matevz.leskovsek@gmail.com>> > To: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > Subject: [PD] Creating/editing patches on android? > Message-ID: > <CAEsQPf7MQ+SLkCzqo848OQ9LweoCUzjVPVHXvQYSfvKZ+Gt5qg(a)mail.gmail.com <mailto:CAEsQPf7MQ+SLkCzqo848OQ9LweoCUzjVPVHXvQYSfvKZ+Gt5qg@mail.gmail.com>> > Content-Type: text/plain; charset="UTF-8" > > Hi all, as I remember all those PD on Android platforms (mobmuplat, > pddroid) only allowed running patches and not editing those, meaning > that one needed a desktop computer to create and edit patches.

Re: [PD] Attaching Xcode debugger
by Dan Wilcox 28 Feb '23

28 Feb '23

You were not unclear. I was trying to be clear that it's probably easier to built Pd yourself than to try to figure out changing entitlements files to trick Gatekeeper. It's not hard and I have to admit I am unwilling to try the linked trick for Supercollider (because I can already build Pd). > On Feb 28, 2023, at 1:26 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 2 > Date: Tue, 28 Feb 2023 11:54:27 +0000 > From: Pierre Alexandre Tremblay <tremblap(a)gmail.com <mailto:tremblap@gmail.com>> > Cc: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: Re: [PD] Attaching Xcode debugger > Message-ID: <4C0811D9-F180-42A3-8643-D149E7F64F72(a)gmail.com <mailto:4C0811D9-F180-42A3-8643-D149E7F64F72@gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Thanks for these > > I was unclear - I?m trying to debug an external (all flags ok) to a downloaded version of Pd and this is where the sandboxing is freaking out lldb.

Sure, but allowing *any* old program to be debugged / decompiled in realtime is not the best for security implications, at least Apple thinks so. Your subject is a little misleading as the "Xcode debugger" is essential lldb. Xcode itself simply wraps lldb when debugging and provides a UI top interact with it. In fact, on a debug build crash in Xcode, you can enter lldb commands directly into the console, ie. "bt" will provide a backtrace directly. > How do people attach a debugger to pd to do development? "lldb" like "gdb" For quick tests of a known crasher, I usually use: make cd bin lldb pd This will use the system Tcl/Tk which has had issues for years now, but is enough for quick testing. For best testing, build the .app and invoke the pd binary inside it. For example: make make app lldb Pd-0.53-2.app/Contents/Resources/bin/pd Once lldb launches, you have to start the process: process launch When a crash happens, you can get the backtrace with "bt", change frames with "f #", and print variables via "v". If you have used gdb before, this is a helpful crib sheet: https://lldb.llvm.org/use/map.html <https://lldb.llvm.org/use/map.html> Note: If you are using a newer macOS system and want to *also* use a newer version of Tcl/Tk, build Wish.app first then use it to make the Pd .app bundle: ./macos/tcltk-wish.sh 8.6.12 produces a Wish-8.6.12.app. Next use it to build Pd .app with: ./mac/osx-app.sh -w Wish-8.6.12.app 0.53-2 Now you can change the C sources and rebuild with: make ./mac/osx-app.sh -w Wish-8.6.12.app 0.53-2 > Do I have to recompile pd myself as the long winded detour? If you want debugging symbols, yes. Fortunately it is relative easy to compile Pd so I don't consider it "long-winded." In fact, we have spent quite a bit of time to make this both possible *and* relatively easy.

Attaching Xcode debugger
by Pierre Alexandre Tremblay 27 Feb '23

27 Feb '23

Hello So we all know how Apple is sandboxing like hell. I have found this article which allows me to modify the entitlements for SuperCollider but the same procedure doesn’t work on Pd. https://stackoverflow.com/questions/69914876/why-xcode-can-not-attach-to-so… How do people attach a debugger to pd to do development? Do I have to recompile pd myself as the long winded detour? Any pointers welcome p
