compiling hidio for Windows
by ffdd cchh 05 Feb '20

05 Feb '20

Dear list, I need to use external controllers via USB with vanilla (say, a PS4 controller), and I have not found a compiled version of [hidio] for Windows. Please, let me know if there are ready-made options out there (feel free to change subject line if that thread goes wild). In the meantime, I am trying to compile [hidio] for Windows. I'm on Windows 10.0.18362, x64-based PC. I am using a MSYS terminal with MINGw64. I took the latest code from Benitoite's repository ( https://github.com/Benitoite/hidio) and I am stuck with "undefined reference"s all over. I attach here the console log. I would very much welcome any idea on how to approach this so I can use vanilla with my students :) Best, f

get average luminance of the camera
by enrike 04 Feb '20

04 Feb '20

hi Is it possible to get the average luminance of the camera input using GEM? I am exploring pix_data but as far as I can see it only works with individual pixels. If I could average or reduce the color information from the camera to a single color, then I think I could just take the pix_data grey value of any pixel. But I am not sure this can be done. I am checking different pix_ objects but I dont see how I could get this to work. Any tips? thanks enrike

by Alexandre Torres Porres 04 Feb '20

04 Feb '20

Hey, do we have people from the San Francisco Bay Area? Anybody interested in me giving a workshop at Center for New Music? It'd be on my work with my tutorial https://github.com/porres/Live-Electronic-Music-Tutorial <https://github.com/porres/Live-Electronic-Music-Tutorial?fbclid=IwAR2xpYXNt…> and ELSE library https://github.com/porres/pd-else <https://github.com/porres/pd-else?fbclid=IwAR26qAgdi5EmuN8z7BBy3Q5yvw3g9D9h…> . If there's interest, we could do something on february 11th. I need to be sure there's interest before we can make this oficial. Thanks, Alex

vbap / deken / ggee
by Jesse Mejia 03 Feb '20

03 Feb '20

I recall a vbap library existing awhile back on deken that included a define_loudspeakers object. The only object I see on deken currently for vbap is the implementation in ggee and i’m wondering if the define_loudspeakers functionality is built in or just missing? The helpfile shows a functioning vbap example but with no loudspeaker definition. I’m also not sure what the object defaults to if nothing is explicitly defined. Does anyone know how this works? If it’s just a matter of documentation i can jump on the ggee github and help out, but I know there are some more complete looking vbap binaries out there.. but I’m having trouble finding them precompiled cross platform. Not sure what the best route is, and as a teacher I’d love to clarify the path to getting vbap up and running more broadly. Thanks! -Jesse

tabread4~ indexing issues
by Jeppi Jeppi 03 Feb '20

03 Feb '20

Hi all, I noticed nasty clicks occur when indexing arrays larger than 16384 samples with tabread4~. I attach a demo file, notice I index the array with a cosine therefore no discontinuities are expected, yet beyond that size I get regular clicks. What is the cause and how could it be overcome? Thanks, josep

Re: [PD] PD Vanilia / Gem / Deken (Dan Wilcox)
by Jérôme Abel 03 Feb '20

Hi, I think a part of my question (How to share Pd.0.50 and Gem 0.94 on Linux ?) was quite the same. I understand that the suggestion is to use "apt" instead of deken on Linux. Just for Gem ? The other libraries seem to work fine with deken. On my Xubuntu machine, "apt" shows older versions of Pure Data (0.48.1-3) and Gem (0.93.3-13), even if I install pd-deken-apt. Any tips ? Thanks. -- Jérôme Abel http://jeromeabel.net

expression with arctn
by Csaba Láng 03 Feb '20

03 Feb '20

Dear list, how would you calculate with an expression this formula: arctg(y/x) looks like tan, sin, cos cannot be in the expression, does it mean I have to brake it into parts? Best, Popesz

Re: [PD] MIDI 2.0 in Pd?
by Dan Wilcox 03 Feb '20

03 Feb '20

In general, the plans seem to fall on whoever needs it first, then whoever wants to actually do it. I overhauled the MIDI handling a couple years ago now, so hopefully it won't be too difficult to extend what we have if someone wants to jump into byte protocols. I'm mildly interested but it will take a while until I can get around to it. > On Feb 3, 2020, at 3:39 AM, pd-list-request(a)lists.iem.at wrote: > > Message: 3 > Date: Mon, 3 Feb 2020 11:28:56 +0900 > From: Julián Villegas <villegas.julian(a)gmail.com <mailto:villegas.julian@gmail.com>> > To: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > Subject: [PD] MIDI 2.0 in Pd? > Message-ID: <EB10B5F8-3FB3-44B3-99C2-2E8DE2C08DFD(a)gmail.com <mailto:EB10B5F8-3FB3-44B3-99C2-2E8DE2C08DFD@gmail.com>> > Content-Type: text/plain; charset=utf-8 > > Hi, > > I came across this: > > https://www.midi.org/articles-old/details-about-midi-2-0-midi-ci-profiles-a… <https://www.midi.org/articles-old/details-about-midi-2-0-midi-ci-profiles-a…> > > and I was wondering if there are plans to upgrade Pd to fully use the new version of this protocol… To be honest, this is an ambitious plan for me to develop myself but I’d be happy to contribute. > > Have a nice week, > > Julian. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

MIDI 2.0 in Pd?
by Julián Villegas 03 Feb '20

03 Feb '20

Hi, I came across this: https://www.midi.org/articles-old/details-about-midi-2-0-midi-ci-profiles-a… and I was wondering if there are plans to upgrade Pd to fully use the new version of this protocol… To be honest, this is an ambitious plan for me to develop myself but I’d be happy to contribute. Have a nice week, Julian.

Maybe it would be helpful to display some text suggesting checking apt-get / the system package manager first when a user opens deken on a Debian system (or maybe Linux in general). > On 2/2/20 9:28 PM, Maurin Donneaud wrote: >> Dear IOhannes, >> >> The issue is : >> The only Gem package I can find with Deken is >> :Gem-v0.0.extended-(Linux-i386-32)(Linux-amd64-64)-externals.tar.gz >> <http://puredata.info/Members/chr15m/software/v0-0extended/Gem/Gem-v0.0.exte… <http://puredata.info/Members/chr15m/software/v0-0extended/Gem/Gem-v0.0.exte…>> >> >> Coould it be possible to get the last version of Gen (94-1) with Deken ? > > why would you? > since you are on a Debian based distribution, you already have *apt*, > which is a far better and more mature package manager than deken. > (on other distributions, you have other package managers; *all* of them > are better than deken) > > anyhow, install the "pd-deken-apt" package (via `apt`), and you can see > (and install) Debian's pd-packages via apt. > (it lacks the object-search though) -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
