new feature for ponies to spit floats at objects
by Jonathan Wilkes 08 Nov '13

08 Nov '13

Hi list, I added a "forwardmess" method for canvases so that you can forward a message to any object on the canvas (by index). This will finally make it possible for Pure Data objects to receive any message a pony happens to spit at it: https://puredata.info/Members/jancsika/pony-spits-numbers-at-Pd.webm/view Best, Jonathan

Re: [PD] Packages for Ubuntu 13.10?
by Szymon 07 Nov '13

07 Nov '13

Hello, I just installed Ubuntu 13.10 and am wondering what repo should i choose, I know about those that might be proper for my ubuntu version: deb http://ppa.launchpad.net/eighthave/pd-extended/ubuntu saucy main (It's the only one that contains package and the package is for 13.10, but is it safe to install it if as Hans-Christoph Steiner says they are untested properly?) deb http://apt.puredata.info/releases stable main (It's a debian one, but if it works (does it?) and fits ubuntu then it would be easier in the future, after new ubuntu release is finished there's always problem with repo) deb http://apt.puredata.info/releases saucy main (there is no package) Best Regards.

Hi Josh, The cppTest does not make any sound, it only runs the patch to test that message sending is working (something quick and dirty I wrote, not meant to be a working example). This is the same as the plain C test. This is by design because there is no default audio api layer in pure C++, as opposed to Obj-C/Cocoa. I'll add some notes to the comments about this. Simply put, you need to call the processFloat, processShort, etc functions in the audio processing callback of whatever audio api you use (PortAudio, Jack, CoreAudio, etc). So yes, the iOS examples do make sound because they use the libpd Obj-C audio unit and audio controller, but the cppTest does not. Also, there has been some work on the Obj-C wrapper so it can work on OSX as well. Has anyone done that/gotten it working? I'd love to get some info/Github pull request on what to change so we can add that functionality.

The patch themselves works fine. Print statements are ok and sending & receiving messages seem ok. But I even built a patch which just *~ two phasors, and couldn't hear it when I used the cppTest code to open my patch. I don't think there is anything wrong with libpd nor my sound card as I compiled & ran the iOSTest project (deployed to a simulator iPhone) and that worked (fuzzy audio, but sound came through). > > Anyone have any good ideas?

could not open midi input 1 (nanoKONTROL SLIDER/KNOB): PortMidi: `Bad pointer'
by Alexandros Drymonitis 06 Nov '13

Even though Pd can see my midi controller, last days I've been receiving this error message as soon as I launch Pd. Anyone knows why this happens?

Re: [PD] [PD-announce] earGram: concatenate sound synthesis/generative music
by Gilberto Bernardes 06 Nov '13

Dear Marco thanks for your feedback. The dimensionality reduction algorithms are not externals...simply abstraction, so, I guess you will not find any trouble running it on Linux. If you run it on pd-extended, I'm pretty sure you will not need other any external libraries, with the exception of gridflow for the computation of eigenvectors in PCA. Look into earGramv0.18>dependencies>abs you will find all abstractions here, or just open the file _absOverview. There's a couple of solutions for dimensionality reduction more or less complex such as: self-organised maps (SOM) PCA haar dct random projection star centroid and star coordinates (the only applied in earGram, actually) best, Gilberto 2013/11/6 Marco Donnarumma <lists(a)marcodonnarumma.com> > Hi Gilberto, > > thanks for sharing your work! > > I'm interested in looking at your dimensionality reduction objects, but > I'm a Linux user.

using rpi_osc_video_player
by Simon Wise 06 Nov '13

06 Nov '13

I've finally got back to working with video on the RPi, and Antoine's player is very useful. I am hoping to add alpha, layers and still images to it, and the ability to seek to the start of the video (at least). The current code is working, playing back the sample test.h264 file nicely but seems only to recognise the .h264 container ... do you know how to convert .mov files (that play well in omxplayer) to that file format? Also I am getting an error when I stop a thread ... OMX_FillThisBuffer(ilclient_get_handle(video_render), eglBuffer) at line 68 of video.c is failing. Simon
