Feature Proposal
by Roman Haefeli 05 Sep '16

05 Sep '16

Hey all After having worked with Python a bit, I'm very intrigued by the many useful data containers it provides (tuples, lists, sets, dictionaries). At the same time, I am sometimes troubled by the inflexibility of arguments in Pd. Writing abstractions that deal with a variable number of arguments is hard. Even retrieving the number of specified arguments inside the abstraction is hard. Also, if you have fixed argument part and a variable part, you need to make sure that the variable part is put at the end of the argument list, otherwise there is no way to distinguish them. I'm just thinking loud here and do not have any idea, how hard it would be to implement in Pd. I'm just trying to raise a discussion about the topic. Here some (probably not very thought-through) ideas: == GROUPING IN ABSTRACTION ARGUMENTS == Allow grouping of atoms, so that you can pass a whole list to one single argument like this: [myabs ( one two 3 ) 4 five] inside the abstraction: $1 would evaluate to 'list one two 3' $2 would evaluate to '4' $3 would evaluate to '5' == GETTING NUMBER OF ARGS == With the same example: [myabs ( one two 3 ) 4 five] inside the abstraction: $# would evaluate to '3' (number of arguments given) == GROUPING IN MESSAGES == [1 2 ( 97 98 99 ) 4 5( | [$2 ( would give '97 98 99' == NAMED ARGUMENTS == [myabs freq=440 vol=1] inside the abstraction: $freq would evaluate to '440' $vol would evalute to '1' If a certain argument is not specified as creation argument, it would evaluate to '0' (similar to existing behavior). == USE CASE == [oscformat] takes an arbitrary number of arguments to create an OSC address. While I find this the cleaner and more pd-like way than /one/two/three, this has big draw-back. You currently cannot pass the OSC address (containing an arbitrary number of address fields) to an abstraction when using [oscformat]. The number of arguments must known beforehand when using this format. With [packOSC] from the osc library, you can do: [myabs /base/address] and therein: [packOSC $1/freq] which evaluates to /base/address/freq. By allowing grouping of arguments, one could achieve the same without resorting to long symbols (which has other drawbacks). In the main patch you could create: [myabs ( base address )] and therein: [oscformat $1 freq] and [oscformat] would actually see 'base address freq'. There are many other cool things you could do. It would allow to create lists of lists, which can be easily split again later (which is currently very hard to do and involves a lot of serializing and using delimiters or prepended number-of-elements). Generally, it would allow to create much more flexible abstractions. Any feedback welcome. Roman

Paper submission, camera-ready?
by Ed Kelly 01 Sep '16

01 Sep '16

Hi Jaime, Will there be a "camera-ready" submission after the announcement date as there is with ICMC? I have references to add, and to update links on the papers I submitted.Also, it would be great to do poster/demo sessions with both the papers I submitted. Is this exclusively paper or demo? or could I do both? Cheers,Ed Kelly Lone Shark releases: Light Vessel Automatic available now on 12" vinyl.Build Your Wings on the Way Down, the new digital album available @ http://scifirecords.co.uk/releases Earthlings compilation is out now @ http://www.pyramidtransmissions.com Ninja Jamm - the revolutionary music remix app for iOS and Android: http://www.ninjajamm.com/ Gemnotes-0.2: Live music notation for Pure Data, and Metastudio 5 live composition and improvisation suite, available at http://sharktracks.co.uk/puredata

Package and sources for complex-mod~ and hilbert~ ?
by Angelo Arcadi 31 Aug '16

31 Aug '16

Hello, when I was using pd-extended I used to use the objects complex-mod~ and hilbert~. Now on Vanilla I don't find them, nor I am able to find them with Deken. Which package they belong to? If I am not wrong they should come with vanillla.... however, pd says "couldn't create" for both of them. I am on a mac osx 10.11.5, using pd 64 bit version 0.47.1. Does anyone know where the sources of these can be found? Thanks in advance Best Angelo

comport + usb hub issue
by Rick Snow 31 Aug '16

31 Aug '16

Howdy list, I am using comport to send messages to three arduinos via osx for an installation. Almost invariably one of the connections drops after an extended period of time. It seems that only unplugging and replugging in the usb hub's usb cable will refresh the connection (after sending the connect message again from the patch). I am running the project on an older macbook pro with osx 10.8.5. Is this a usb hub problem (radioshack brand) or should I be looking at something else? Advice/Experiences appreciated! Cheers, Rick

legal issues with reverse engineering proprietary software (such as Max)
by Alexandre Torres Porres 28 Aug '16

28 Aug '16

Howdy, perhaps you wise folks can help me think about this topic. What are legal issues with reverse engineering proprietary software as an open source project, what are the boundaries when it is not ok anymore? Sure I'm more interested in the case of cloning Max/MSP to Pd as in the cyclone library, but it's a generic topic anyhow that can be broadened. But if we're to discuss this particular case, does Cycling hold the power to sue and prevent cyclone from being distributed? It's not like their code is being used anyway, or some patented/proprietary algorithm is being "stolen". It's all about *reverse engineering* it and having same functionality as objects with the same name... and I don't think you can hold the rights to that. Maybe if you were to clone the whole damn software exactly, and be able to save files in the max format and everything... then you'd be on to something... I think you'd cross the line with that one... well, that's what I have for now, thanks cheers

LibPD for .NET and Mono now available from NuGet
by Thomas Mayer 26 Aug '16

26 Aug '16

Hello, I have uploaded and fully functional version of LibPD for .NET and Mono to NuGet: https://www.nuget.org/packages/LibPDBinding I have opted to number the versions independantly from LibPD itself, as new packages may be uploaded with new architectures and OS. It has been compiled using the latest release 0.9.2 plus my two pull requests: https://github.com/libpd/libpd/pull/113 https://github.com/libpd/libpd/pull/139 Included are native libraries for Windows and Linux, both x86 and amd64, as well as the necessary .NET and Mono dll. For an example on how to use LibPD with C#, take a look at the sample app: https://github.com/residuum/libpd/tree/csharp/samples/csharp/naudio I have already toyed around a bit with it: https://github.com/residuum/premier-league-sonification/tree/master/CsharpD… Thanks, Thomas -- "Ich komme aus dem Staunen nicht heraus."
