[PD-announce] Pd-extended 0.43.4 beta release, its almost done!
by Hans-Christoph Steiner 05 Nov '12

05 Nov '12

So in a little burst of activity, there has been new work on the Pd-extended 0.43 release. A bunch of bugs have been fixed, a new Windows XP build server is up and running, a couple of bugs are still outstanding. Overall, things are looking good and ready to go! Unless you are affected by one of the bugs listed below, I think that this beta version is already much better than the last release. You can get it here: https://puredata.info/downloads/pd-extended/releases/0.43.4 If you are running Ubuntu or Linux Mint (lucid thru quantal), you can add this PPA to automatically find and install Pd-extended beta updates: https://launchpad.net/~eighthave/+archive/pd-extended/ Running this command in the Terminal is the easiest way to add this PPA to your machine: sudo add-apt-repository ppa:eighthave/pd-extended Unfixed bugs ------------ These are the bugs that are not yet fixed. If you can help with them we appreciate all the help we can get.

vline~ precision under lower block sizes
by João Pais 05 Nov '12

05 Nov '12

Hello, a friend noticed that vline~ behaves differently with different block sizes - namely that the smaller the block size is, the less precision it has. Besides the numbers being different with each block size, the latest values go slightly over the border of the desired range. Is this a bug, a feature, or an unavoidable behavior of the vline~ algorithms? Attached is a patch which explains the situation. I think it should be clearly enough explained. The bottom line is: in the patch I am working, block size is 1 (sample rate 48KHz, in case it matters). Which choices are there to improve vline~'s precision, so that I get the results I am expecting? Thanks, JoÃ£o

Recording audio to mp3 using LAME or ffmpeg ?
by Pierre Massat 04 Nov '12

04 Nov '12

Dear List, How would you go about recording the audio output of a Pd patch directly to mp3 (or any other compressed format actually), without using the object from the Unauthorized library ? Would it be feasible to use the [shell] object with a script using ffmpeg or LAME ? I don't really know whether there would be serious timing uses, who to use those for recording a stream instead of a file, how to send Pd's audio out... I could always record to wav and run a script afterwards to compress and delete the original file, but i'd rather have something more direct. Cheers, Pierre.

increasing and decreasing values using keyboard
by Rick T 03 Nov '12

03 Nov '12

Greetings All I'm trying to see if their is a better way to increase and decrease values using the keyboard. At the moment the only way I've figured out to increase and decrease values using the keyboard is to 1) Create "function" for keyboard increasing value 2) Create "function" for keyboard decreasing value 3) Combine "functions" using bondo with expr to calculate value. Is their a better way to do this it seems convoluted. See attached PD PS: I'm using PD-extended .43.4 on ubuntu 10.04 Linux 64bit

I prefer the GPL myself, however it's not compatible with iOS. My opinion so far, is that the iPad is the best hardware for what I need, so I've chosen to work with that for now. Once the OpenFrameworks ARM port is working much better, I have the option of going Beagle/Raspberry PI. > BTW i think Robotcowboy looks great, although i was also curious where Chris M's PdParty (iOS version of DroidParty) alpha port went. The code is still there on Github. I decided last fall, that I was spending too much time on that as a narrow exercise and really needed to get the app going on a larger scale. My plan is to reintegrate that back into the rc app, so guis in a scene's _main.pd will show up on the screen. This way, the app can be used for graphics, graphics+pd, or pd only. As I said before, I want a flexible workflow and using the pd guis for an audio only scene is a great option. Development is going hand in hand with work on my artistic thesis at the same time: a live a/v show about going to Mars. Updates may be slow in coming for a little while. The intent, however, is to use the app for the live show and song making, so I definitely have deadlines ... ------------- Mars One Way NASA and commercial space companies are working towards sending humans to Mars by the 2030s. In fact, the Mars One project states that by utilizing existing technology, we could send colonists to the Earth’s red neighbor in 2023 ... albeit on a one way trip. Half the equipment, half the fuel, half the cost for a human settlement without a return option. Would you go? Mars One Way is a live, audio visual show which explores this question through a figurative journey to Mars and subsequent colonization: from training, liftoff, the 3 months to Mars, landing, and colonization. Based on hard science fiction and current/future NASA and commercial space plans, the show is meant to both educate and entertain, while posing large questions into the nature of human colonization and it’s inherent risks and rewards. -------- Dan Wilcox danomatika.com robotcowboy.com

Re: [PD] PKGBUILD of pd-extended 0.43-4 for Archers
by Fero Kiraly 03 Nov '12

03 Nov '12

Thanks to Hans suggestions I made a research why I cant compile pd-ex from branch. It takes me some time but I found that was something wrong in GEM configure.ac script. So I did it ! https://aur.archlinux.org/packages.php?ID=44798 ---> should be the correct build package script for the latest pd-extended It is made from: https://pure-data.svn.sourceforge.net/svnroot/pure-data/branches/pd-extende… + git://pure-data.git.sourceforge.net/gitroot/pure-data/pd-extended.git {I apologize all the guys who liked pd-extended with the latest GEM, but (I understand this) it is 'official' package of pd-ex, now.} fero

rjdj is gone, robotcowboy is coming ...
by Dan Wilcox 03 Nov '12

03 Nov '12

Hey all, So it seems the rjdj app is off the iOS app store already :( Just letting you know I have an alternative coming for running pd patches on iOS & desktop: the robotcowboy app. It's basically my performance environment as an app including pd, midi, osc, and a Processing-like lua scripting environment. I could use some help on beta testing, website work, etc soon since I'm trying to get this out *while* planning/working on my masters thesis project (robotcowboy is going to Mars!). Any help would be greatly appreciated. This app is being built in OpenFrameworks, so it works on Mac/Win/Lin & iOS. Android support could be added, but I don't have an android device. https://github.com/danomatika/robotcowboy -------- Dan Wilcox danomatika.com robotcowboy.com

Re: [PD] Licensing issues (was rjdj is gone, robotcowboy is coming ...)
by Peter Kirn 03 Nov '12

03 Nov '12

Hello, I just want to chime in here. I don't think it's accurate to say pd-extended is "GPL." pd-extended is essentially a distribution of externals, abstractions, and other conveniences. Obviously, developers are free to use what license they want. Yes, libpd and Pd-vanilla use an extremely permissive license. I believe it's possible to develop free software for iOS. I think on reflection it makes a stronger statement to reach that platform - locked-down as it may be - with free software than it does to ignore it. This means using a BSD- or MIT-style license and not GPL or LGPL; the earlier thread was right. Note that I think you *can* use a copyleft license for your patches, because these will run independently of iOS. There are other reasons - compatibility and simplicity being foremost - to favor vanilla in development with libpd whether or not you're using iOS. I think we may be overstating the problem here a bit. In other words, yes, Apple has a problem with GPL. But libpd developers I think don't have a problem with Apple, if that makes sense. And I think we make a stronger statement by showing how well the free solution works than we do banging our head against a brick wall. I believe in the GPL license, which is why we're using it on MeeBlip. But I think the short answer is, use BSD with libpd, try to default to vanilla, and maximize the contexts with which your software can be used. Add GPL or copyleft to patches to encourage others to share. That for me seems a pretty nice solution. Now, Apple aside, it does seem that it makes sense for external developers to use the same license as Pd. (Patches and abstractions are a different issues, because they're effectively content rather than part of your code.) But that's up to developers. Peter
