line: grain rate and delta
by tim vets 21 Oct '10

21 Oct '10

Hi all, I'm a bit confused about the grain rate of [line] the help says that 'the default grain rate is 20 ms' however, when I connect a [delta] to a [line], it shows zero's, while inserting a [speedlim 20] changes that. also some other tests in attached patch. can someone explain ? Thanks, Tim

Loop point : a way to make it smooth?
by Pierre Massat 21 Oct '10

21 Oct '10

Hi all! I've made a looping patch for a friend who needs to create a musical piece for her school. She's complaining about the fact that she hears when the sample loops back to it's beginning. I tried to envelop it using a table to control the volume which just ramps up from 0 to 1 during X ms (X being adjustable), outputs 1 during most of the sample except for the last X ms where it ramps back down. The ramps are not linear, they have sort of an inverse square shape. This doesn't really do the trick. I've been thinking of writing the sample to 2 tables, one delayed by the length of the sample minus X ms, so that i can play both tables and switch between the two to avoid having to bring the volume to 0 at one point. The sample needs to be X ms longer. Is there another way to go? I've been doing some research on the web, but i've found no satisfying answer. Thanks! Pierre

Re: [PD] bpm counter
by patko 20 Oct '10

20 Oct '10

Hello, I'm working on a bpm counter for soundfiles only, and get an high percentage of good results with little drums loops. This patch detects only binary rythms, maybe it will be possible to make this realtime... ----- "L.J." <potaxpotax(a)gmail.com> a écrit : > before building something that's already there, has anyone done a > working bpm counter in pd? > > _______________________________________________ > Pd-list(a)iem.at mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list -- Patrice Colet

pduino + arduino UNO
by alessandro contini 20 Oct '10

20 Oct '10

hey there, i'm teaching in an intensive course about Arduino in an italian design school. some of the students are using Pduino for their final projects. the point is i have a student who bought the new Arduino UNO board, we tried to use it with Firmata 2.2 and Pduino, but it doesn't work. when loading the arduino-test it loads only a part of the patch in the console view. it recognizes the board as an Arduino UNO, but then it says "can't create" i tried to search for the problem with google, but we haven't found anything useful. maybe someone encountered a similar problem? :) alessandro contini + www.cntlsn.com

by Mathieu Bouchard 20 Oct '10

20 Oct '10

---------- Forwarded message ---------- Date: Wed, 20 Oct 2010 01:10:55 -0400 (EDT) From: Mathieu Bouchard <matju(a)artengine.ca> To: pdmtl(a)artengine.ca Subject: pdmtl#37 Trente-septième rencontre du club d'utilisateurs de PureData de Montréal à Vidéographe, au 4550, rue Garnier (coin Mont-Royal) Le samedi 23 octobre 2010 de 13h00 à 17h00 1. Pure Data et les Larseneurs (Thomas Thiery) La présentation "Pure Data et les Larseneurs" a pour objectif de présenter deux "patchs" utilisés par le projet de concerts ou d'interventions dédiés aux larsens, "Larseneurs". Elle se déroulera en trois temps, l'une consacrée à la présentation du projet et des actions réalisées puis par la présentation du "patch larsenophone" simple et enfin la description du "patch larsenophone réseau". Larseneur : http://larseneur.net Thomas Thiery : http://www.th-th.fr 2. Nouveaux externes dans la librairie "tof" (Thomas O. Fredericks) Je présenterai quelques externes d'interface-utilisateur, et le système de routage/gui/paramètres/sauvegarde param (version «release») 3. Thomas O. Fredericks va me poser des questions sur ma présentation passée à propos de la nouvelle façon de faire de l'OpenGL dans GridFlow 9.11 ([gf/gl]). 4. On parlera un peu de ZenGarden (http://github.com/mhroth/ZenGarden) 5. Le Cyc (Martin Eckart) For the project I built a projection system in PD-GEM which allows the artist to "perform" the visuals (including panning/zooming) in real-time with the band. It's a glorified slideshow but I'm proud of it :) We're performing that and our newer project "Hello Adventure" (no online samples...yet. More of a stop-motion animation piece) in Montreal this coming weekend and in other parts of Ontario through early November so if you're in the area please do come say hi. http://www.polydactylhearts.ca/?page_id=397 _______________________________________________________________________ | Mathieu Bouchard ------------------------------ Villeray, Montréal, QC _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Latency under Linux/Jack (again...)
by Raphael Raccuia 19 Oct '10

19 Oct '10

Hi list, I tested Pd rt as I need low latency for a performance next week... It seems -rt flag doesn't have any effect. I measured Pd latency with jdelay, and always get 640 (@48000), so about 13ms (pd only)... lower I set buffer in jack (no less than 256), more DIO errors I get... and there are a lot! This setting works great with many application (Ardour...), with about 10ms (~15 really). So I would have ~25ms, which is acceptable, but too many DIO errors! -what is -defeatrt setting? (I tried 0 and 1, no change) -why is -rt flag without effect? -tried nosleep, no change... I also tried to start pd in root (sudo)... It says: priority 8 scheduling enabled. priority 6 scheduling enabled. (which I normally don't have) but unfortunately can't connect to jack (state 17) thank's for your help

Hello, Would like to build for 10.5.8, Pd-extended. Using a macbook Pro, dual core , 2.5, 4 gb ram. Have had troubles with both the build using git - when calling from the terminal, it opens with limited time - I wish it would run, and have all needed Fink files after 10 days... My fink tcltk is 8.4.19-3, and I had to install 8.5 as a binary after the 8.4/8.5 source builds failed (svn) the pd-extended svn also fails after a few functions, even after I downgraded all fink versions to be explicitly the same as listed on the dev page. Of course I also removed all other versions of pd from usr/. Only gmp is higher (gmp5 5.0.1-5, gmp5-shlibs) though the gmp-shlibs is still 4.3.2-5. Any ideas of possible conflicts, libraries to remove or upgrade, would be welcome. cheers, MJ

Graphic Novel Opera
by Martin Eckart 19 Oct '10

19 Oct '10

Hi list, Just wanted to send out a link to my group's graphic-novel (rock?) opera "Le Cyc" that we recently released online: http://www.polydactylhearts.ca/?page_id=397 For the project I built a projection system in PD-GEM which allows the artist to "perform" the visuals (including panning/zooming) in real-time with the band. It's a glorified slideshow but I'm proud of it :) We're performing that and our newer project "Hello Adventure" (no online samples...yet. More of a stop-motion animation piece) in Montreal this coming weekend and in other parts of Ontario through early November so if you're in the area please do come say hi. Cheers, -martin
