[PD-announce] share-mem lib
by Cyrille Henry 10 Jul '13

10 Jul '13

hello, i just did a initial commit of share-mem, a lib dedicated to deal with shared memory. background : pd / pd~ communication is really slow. by example, having a pd~ patch with 8 audio in and 8 out, use about 50% cpu of a recent computer for each process only to deal with audio communication. sending a large array from one process to the other is almost not possible in RT. This really limit pd~ usability. ----- Thanks to share memory, communication between process can be greatly improve. This lib is mainly composed of an external, and few abstraction and examples. Everything look stable, at least on a ubuntu (12.04) and a osX laptop. Implementation follow POSIX standard, so it will unfortunately not work on windows. everything that I need is there, even if lot's more work could be made. I hope to have user feedback before making more development. Cheers Cyrille _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Hello list, Excuse the hassle... But I think this very important .. The windows version of pd-extended 0.43 don't have support to Jack.. It would be great can connect my new pd extended release to ableton live to play a little.. -- Esteban Viveros (27) 8815 7170 (27) 3066 0359 (11) 95761 4125 (11) 2738 7868 www.bandpage.com/estebanviveros <http://soundcloud.com/estebanviveros> https://www.facebook.com/estebanviveros.art http://www.papodecompositor-es.blogspot.com.br/ http://expurgacao.art.br/

PD 4 Pandora
by dreamer 12 Mar '13

12 Mar '13

I've been trying to compile Puredata for the Pandora handheld. Getting the UI to work with tcl/tk 8.5 was fairly straightforward, although the terminal is filled with: watchdog: signalling pd... Otherwise I'm having a lot of issues with alsa. When selecting alsa as output I get: snd_pcm_hw_params (input): Invalid argument snd_pcm_hw_params (output): Invalid argument In the settings I can select two alsa devices: omap3pandora (hardware) omap3pandora (plugin) Which both fail. When I select portaudio output I get: pd: src/common/pa_front.c:325: Pa_Initialize: Assertion `"PortAudio: compile time and runtime endianness don't match" && (((char *)&nativeOne)[0]) == 0` failed.Pd: signal 6 And it crashes. Are there some configure flags to mitigate these problems? Some more info on the device in question: http://en.wikipedia.org/wiki/Pandora_%28console%29#Pandora_1GHz Any ideas to get this working are welcome :) regards, drmr

Midi note handling for monophonic synth
by Joe White 25 Feb '13

25 Feb '13

Hi all, I'm implementing a synth in Pd using midi/notein as an input. One problem I keep coming up against is handling note off messages. This guy's blog post describes the issue - http://kemptonmooney.com/2010/09/pure-data-midi-note-off-solution/ However, I think his solution is not exactly what I'm looking for. The synths I use in Logic have note priority methods and remember all held down notes (or at least 10). I wondering if anyone has managed to implement something like this in Pd or might know where I can find out more about it. ddg.mono from Max ( http://www.cycling74.com/docs/max5/refpages/m4l-ref/ddg.mono.html) looks similar to what I want - but I don't use Max and I don't think I can access the source. Any ideas? Thanks, Joe

GUI overload
by Ed Kelly 15 Feb '13

15 Feb '13

Hi List, I'm not going to say whether this is a "recurrent" problem as it's hard to say whether the rewrite of the GUI has affected it... I'm using a lot of abstractions with larger GOP or non-GOP GUIs, and I find the following problem occurs. There comes a point where the GUI objects stop responding in a patch when it is reloaded. I am wondering if there is a specific limit to GUI objects that could be changed. I think Pd is making some kind of decision that "there's too much of this stuff - I'm gonna prioritize the audio and not worry about it" and I'd like to know how or if it is possible to control this process from within Pd, or by setting flags on the command line. I'm also making less GUI intensive versions for performance time, since the really big GUI patches are often pattern-sequencers which I will not want to program when I am performing. Example patch enclosed to give you an idea. The really GUI-intensive objects are the trackers, especially quadtracker (which I think has pushed the GUI of Pd patches about as far as I can go now). System: quad core i5 PC running Ubuntu (10.04 Lucid), Pd-0.43-4, lots of externals compiled and loaded. Warm wishes, Ed Gemnotes-0.2: Live music notation for Pure Data, now with dynamics! http://sharktracks.co.uk/
