pd~ subprocess
by tim vets 22 Apr '11

22 Apr '11

Hi all, I'm trying out pd~ for spreading workload over multiple processors, and thus increase performance. but if I load my [subproctest] as an abstraction, it doesn't cause clicks, while with: [pd~ start subproctest.pd( | [pd~ -ninsig 8 -noutsig 8 -fifo 20] ...clicks galore... (pd-extended 0.42.5, ubuntustudio Hardy, qjackctl, RME hdsp, intel core i7 processor) any tips? thanks, Tim

Re: [PD] Midi note handling for monophonic synth
by Joe White 21 Apr '11

21 Apr '11

Hi Claude, Thanks for the info, how are you searching the list btw? Found this in the search you linked: "i coded two simple externals that do the job (and tell you the gate status also, eg. if there are notes pressed or not). you can find on my (under construction) website http://xaero.ath.cx/cms/software' It's sod's law that the link is broken :( > If the order of key presses matters, you could keep an ordered list of > pressed notes (example below using Haskell to prototype the algorithm) > and sound the most recently pressed note that hasn't been released: This exactly what I want, although I don't know Haskell at all, sorry. I can keep an ordered list with just one item, however, using item pairs (pitch, velocity) gets more difficult with how Pd handles commas (i'm assuming comma is the best way to keep a separated list).

If pitch is the only thing determining which notes should sound, you could use a [table $0-active 128] (one index for each MIDI note) to count how many times each note has been pressed and not released, then process it how you like. If the order of key presses matters, you could keep an ordered list of pressed notes (example below using Haskell to prototype the algorithm) and sound the most recently pressed note that hasn't been released: ----8<---- $ ghci ... > let soundingNote = listToMaybe > let noteOn note vel notes = (note, vel) : notes > let noteOff note vel notes = deleteBy ((==)`on`fst) (note, vel) notes > let noNotes = [] > let test = noteOff 62 60 . noteOn 60 60 . noteOn 62 60 $ noNotes > soundingNote test Just (60,60) > soundingNote (noteOff 60 25 test) Nothing ----8<---- > I wondering if anyone has managed to implement something like this in Pd or > might know where I can find out more about it.

Gem: 12 Screens
by Max 21 Apr '11

21 Apr '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi List, what's the best hardware approach to render 12 screens with Gem? A computer with a quad head GFX card and four triple head2go? or better for synced computers? The screens display multiple movies at the same time which change their positions and the bezels of the screen shall be subtracted from the image (gemframebuffer)... Anyone has done that before? max -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iEYEARECAAYFAk2wGWMACgkQ3EB7kzgMM6IxfACZAWvwZ4ZcUf4Osf0bA682q3Nb B7EAnRtJ1/IdK4nBd9QnJ2snMDfsy1OG =7cNx -----END PGP SIGNATURE-----

There's a nice article about Miller, Pd, and artists who use it in their work in the San Diego City Beat: http://www.sdcitybeat.com/sandiego/article-8972-the-language-of-invention.h… It also mentions the Inception app and the pd-LAunch event in San Diego on Monday. -Theron ^

[PD-announce] [Pdmtl] Formation sur PureData à l'UQAM – 10mai-2juin 2011 (fwd)
by Mathieu Bouchard 20 Apr '11

20 Apr '11

Pd course at UQÀM in Montréal next month. 8 evenings times 3 hours = 24 hours total. Open to everybody (not restricted to students, not restricted to residents of Île-de-Montréal, etc) ---------- Forwarded message ---------- Date: Wed, 20 Apr 2011 09:33:43 -0400 From: Claude Lebeuf <claude_lebeuf(a)hotmail.com> To: pdmtl(a)lists.artengine.ca Subject: [Pdmtl] Formation sur PureData à l'UQAM – 10mai-2juin 2011 Bonjour. Je voudrais vous faire part d'une formation sur Pure Data qui démarrera bientôt. Cette formation, proposée dans le cadre du SITel (Service de l'information et des télécommunications de l'UQAM), est ouverte aux étudiants ainsi qu'à la communauté. Il s'agit d'un cours de 24 heures, étalé sur 4 semaines à raison de 2 soirs par semaine. Le cours sera de niveau débutant-intermédiaire, c'est-à-dire qu'il devrait permettre à des gens qui ont déjà quelques connaissances en la matière (par exemple avec MaxMSP) de comprendre le fonctionnement de Pure Data et ses particularités. Avec la permission de ses auteurs, le cours utilisera dans une bonne mesure le récent manuel FLOSS, produit en français au début de l'année par une équipe d'utilisateurs. http://objavi.flossmanuals.net/books/Puredata-fr-2011.02.11-20.53.23.pdf Le minimum d'inscription nécessaire pour démarrer le cours est de 10 personnes. Le plus vite se font les inscriptions, le plus d'assurance nous aurons que le cours démarre. Et, si l'intérêt est assez marqué, il pourrait y avoir répétition à l'avenir... Une bonne façon de répandre l'utilisation du logiciel libre et d'appuyer ses contributeurs. Merci d'en parler autour de vous.

pd & firewire in the Natty Narwhal
by batinste 20 Apr '11

20 Apr '11

Hi list I've upgraded my Ubuntu to Natty Narwhal beta (kernel 2.6.38-8 x86_64). I'm trying to run pd 0.42-6 (from the ubuntu universe repo) with jackdmp 1.9.7 and libffado 2.999.0, on my Edirol FA-101. This was running nice on Ubuntu 10.10. I launch jackd with : jackd -P70 -p128 -dfirewire -r44100 -p256 -n3 As soon as i click "Apply" to select the jack backend in pd, its telling me : jack_client_new: deprecated JackSocketClientChannel read fail Cannot open pure_data_0 client and Jackd then answers : JackFFADODriver::ffado_driver_wait - unhandled xrun firewire ERR: wait status < 0! (= -1) JackAudioDriver::ProcessAsync: read error, stopping... JackProcessSync::LockedTimedWait error usec = 5000000 err = Connection timed out If i only launch jack, after some time i get : JackFFADODriver::ffado_driver_wait - unhandled xrun firewire ERR: wait status < 0! (= -1) JackAudioDriver::ProcessAsync: read error, stopping... Do anyone here got the same issue ? I have found that the right method to open a jack port is now jack_client_open(). It seems that pd 0.42-6 is not using this method.

PdDroidParty - play your unmodified Pd patches on Android devices
by Chris McCormick 19 Apr '11

19 Apr '11

Hello, PdDroidParty is, I think, the easiest way to get your patches running on your Android devices. It emulates Pd native user interface elements (only toggle and slider implemented so far) so all you need to do is name your patch droidparty_main.pd and copy it to your SD card. Download and install the apk from here, and then try out the drum machine example by unzipping it to your SD card: http://mccormick.cx/projects/PdDroidParty/ This is beta software hot off the compiler, but I think it's just ready enough for use. As always, patches welcome! Goodnight! Chris. PS oh yeah, get the source like this: bzr co http://mccormick.cx/dev/PdDroidParty/ ------------------- http://mccormick.cx
