plans for Pd 0.48
by Miller Puckette 17 Apr '17

17 Apr '17

Hi all, I'm now ready to start working toward the next Pd release (0.48) . I've barely touched the Pd sources since the 0.47-1 release last June, and meanwhile picked up lots of ideas from the Pd convention and always have my own long list of things to do. In the interest of transparency I'll try to map out my plans for the 3-ish months I think it will take me to get to 0.48. I'll only be advancing rather slowly before Feb. 4 because I have two separate music production projects before then; I'll start working faster after that. First thing is always to merge in as many patches and pull requests as I can. I get these from two sources: sourceforge (https://sourceforge.net/p/pure-data/patches/) and github (https://github.com/pure-data/pure-data/pulls). At the moment I don't prioritize one of those above the other. I do this first because, when I enter a period of heavy code editing I risk causing conflicts with patches/pull requests and I don't want to create extra work for contributors. In a few days I'll start on my own changes, with the major ones first so that there's extras time to get them decently debugged; then while bugs in the major changes are surfacing I can take on a larger list of smaller changes. The major changes I want to try to put in this release are as follows: 1. Make a stab at making Pdlib callable from multiple threads. There's a suggestion from Peter Brinkmann in which gensym() (and I presume by extension, pd_bind() etc) would be protected by a lock. I have an alternative idea I'd like to float; I'll do this in a separate message to follow. 2. fix "preferences" so that you can load/store them explicitly to files, and offer an option to delete all "system" preferences ("defaults" on mac; registry info on Windows). 3. Adapt and incorporate the Pd-llork/purr-data "infinite undo" feature. Since the code has diverged I'll probably have to extensively rewrite it to work in Pd vanilla. 4. fix the DSP sorting mechanism so that objects can sense whether they have signals connected and, if not, avoid having Pd automatically generate fake signals for them to use. This way, for example, "+~" can finally detect whether it's got a signal connected without having the user have to tell it via "+~ 0". Also, then the filters (hip~ etc) can then be upgraded to allow signals for filter parameters, without doing the extra calculations if there's no signal connected. This will require adding something to the "DSP" mechanism; I'm still not sure how to do this in the best way. 5. Make a binary "FUDI" format for pd~ objects, and perhaps also offer it as an option for netsend/netreceive (I'm not sure if that's needed or not - maybe the existing "-b" binary formatting can be used in conjunction with some new formatting/parsing objects to allow passing floats and symbols around in binary messages instead.) 6. Hack at sigmund~ to add some features it needs. This is a long list and I probably won't get to all of it. Then I'll move onto all the smaller changes, which are too numerous to list here.

.pdrc?
by Peter P. 15 Apr '17

15 Apr '17

Hi, I find that my Pd does do autopatching despite -noautopatch being specified in my ~/.pdrc which makes me wonder if that file is read at all? Or has the name/location of pd's config file changed by now? This is with Pd-0.47.1 ("") compiled for Debian (0.47.1-3) installed via Debian apt. Thanks! P

Good morning, i receive osc data through netreceive into pd. How can i netsend these data outside from pd ? Could someone please make me an example ? Thanks a lot.

sending motion messages to subpatch
by a. adhiyatma 15 Apr '17

15 Apr '17

Hi everyone, I'm trying to get my subpatch to move around in its parent patch by sending it the message [motion x y z( unfortunately when I send the message the post window shows "consistency check failed: editor" I've attached a snippet to show the problem. I'm curious if anyone else is getting this bug, if it's a no-longer supported holdover from extended, or if there's another way to do this. I'm using Pd Vanilla 0.47-1. Thanks in advance! A.

Re: [PD] Formant from SC in Pd?

Though I get the idea that the fof-filter thingy is based on a bank of such filters, huh? "Formant", on the other hand, is described as an "oscillator", it "generates a set of harmonics around a formant frequency at a given fundamental frequency", has parameters for fundamental frequency, formant frequency and bandwidth of the formant frequency. I'm really curious on how to implement it as a pd patch ;) - but I don't think I've seen anything like it in the Pd world. cheers

Formant from SC in Pd?
by Alexandre Torres Porres 14 Apr '17

14 Apr '17

Howdy, you people have an idea of what that Formant UGen from SuperCollider is? I'm wondering how to recreate it in a Pd patch, or at least find some references to what it is. thanks

[PD-announce] batchrecord library - alpha release!
by Christof Ressi 13 Apr '17

13 Apr '17

Dear list, I just finished a tiny library (actually just one abstraction and one external) which allows to stream audio to disc in zero logical time (= as fast as possible). this is basically the same as running Pd in batch mode (i.e. with the -batch flag) - but you can do it within the usual interactive mode! My first approach was single stepping DSP with [switch~]. unfortunately, it doesn't work with clock objects like [delay], [metro], [line] because clock timeouts are tied to the global scheduler. replacing an [until] to [switch~] with a very fast [metro] at least allowed clocks with delay 0 to time out (e.g. [bang~], [env~] etc.). Finally, I went for the most naive solution: I wrote a simple external which calls sched_tick() whenever it receives a bang. what shall I say: it works :-D. this library made me very happy, because it allows me to render any number of seconds/minutes/hours of a patch to disc without leaving the interactive mode. this way I can have a nice big chaotic patch, tweak it till I have the right settings and then just write like 1 hour of sound material in just a few minutes. Now I just rendered 15 minutes of super-timestreched Henry Mancini. I'm pretty sure someone has already had this idea but I didn't come across anything... here you can download the alpha release: https://git.iem.at/ressi/batchrecord for Windows, it should work out of the box. Linux and OSX users just have to compile [schedtick] with "build.sh" (you're of course warmly invited to send me the binaries :-) Any kind of feedback is highly welcome! I tested on Pd 0.47.1 on a Lenovo Thinkpad with Windows 7 and couldn't find an issue yet. Once I know that it is stable and safe (which I'm not totally sure about...) I will make a proper release and upload to the Deken. Have fun!

switch~ default off?
by Matt Davey 13 Apr '17

13 Apr '17

i've always been annoyed that [switch~] is off by default. could we at least get a creation argument to turn it on??? Miller? Please?

I have no intention of updating GEM for OpenGL ES and/or to support GEM on iOS. It’s definitely *possible* but beyond my current time, energy level, and personal project requirements. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

help compiling a pd external
by Pagano, Patrick 13 Apr '17

13 Apr '17

hello i am hopeful somone might be able to help me convert a max external into a pd one https://github.com/DanBennettDev/db.bounce this is a cool approximation of a peter b chaotic triangle wave and i was wondering if anyone here could compile it for linux? I don't have a linux distro on a working machine at home so i figured someone here might be interested cheers~ pp [https://avatars2.githubusercontent.com/u/10479778?v=3&s=400]<https://github.com/DanBennettDev/db.bounce> GitHub - DanBennettDev/db.bounce: Max MSP audio external ...<https://github.com/DanBennettDev/db.bounce> github.com README.md db.bounce.
