Re: [PD] settings on Ubuntu

Hi Ivica, list... it turns out both of them had vanilla Pd installed. They downloaded extended packages and installed them and everything went fine from there.

Re: [PD] Which Linux distribution are you using?
by Marco Donnarumma 14 Nov '10

I'm also having real good experience with Ubuntu 10.4 (slightly customized with the UStudio packages). I agree that only Firewire devices performance seems to really improve with a RT kernel. In RT with a Ricoh chip and FFADO from svn I can have 8ms latency (I only tried using 6 channels and 8 i/o open), although I have to note that a few times with heavy load of audio streaming amongst different applications jack dies and needs to be restarted. I didn't need to set IRQ so far. In non-RT I use a edirol ua-25 which works pretty good with low latency too (but not as good as firewire rt).

Musical notation object on Pd
by Caio Barros 14 Nov '10

14 Nov '10

Hello guys. I've been dreaming about an object that would display musical notation and output data (like midi numbers for instance). I found a discutions about something like that here in our list ( http://www.mail-archive.com/pd-list@iem.at/msg19969.html) but this was a discussion about creating live musical notation for performance, and what I have in mind is something more like a Computer Assisted Composition/Research tool. If i'm not mistaken Open Music and PWGL (http://www2.siba.fi/PWGL/) already have something like this. Look at the images I made of how this object would look like: - The input would be a message with the midi number of the pitch, and the object would display a Treble or Bass cleff with the note and output the number of the pitch through the outlet (cleff_pd_01.png). - It would be possible to alterate the pitch by holding and dragging the mouse (cleff_pd_02.png) - Chords could be made... (cleff_pd_03.png) - or melodies... (cleff_pd_04.png) - or even sequences of chords. (cleff_pd_05.png) The output could easily be transformed into notation for lilypond, for instance (like Collin Oldham did in that thread I mentioned). Do you think it's possible to do something like that? At the moment I don't have the money to pay a programmer to do that (I would happily do it if I could). Maybe I can learn how to do this, but I don't know where to start. I already see some complications to build this object: - it would have to stretch itself so the chords and melodies would fit; - It would have to decide what cleff to use (or maybe not, the user could send a message like [treble<); - There should have a way to choose between flat and sharp; - A nice thing would be to have more than one staff at once, like a piano staff for instance, and so on... For now I'm just wondering if something like this could be done. I've been doing some calculations of composition techniques using Pd and I miss musical notation so much. Bye! Caio Barros Bonus: I made an abstraction to transform midi note to pitch name and also frequency as a part of a bunch of composition tools I use. (and after I read those threads about creating the notation object in GEM I discovered that some people already did it, but here it go anyway). see midi_note.pd

Before this the midi notes needs to be scaled, with that way it's possible to make up any scale maybe it would be better to use another class object for the scale as well.

pd~, 2 gemwin, vsync, nvidia, linux
by cyrille henry 14 Nov '10

14 Nov '10

hello, i'm using a gem patch inside a pd~, in order to separate a huge computation, and the rendering of this process. But since i need pix_image/pix_data in the 1st process, i have to open 2 gem windows. only the 2nd one is visible. i'm using export __GL_SYNC_DISPLAY_DEVICE=CRT-0 do have vsync on the external screen. (don't understand why nvidia-setting did not work any more for this) my problem is that only the 1 gem windows is sync to Vblank. but i need the 2nd to be synchronize. i could modify all my patch in order to have the rendering in the main pd patch and computation in pd~, but that would be a huge work. So i'm looking for a way to force sync to Vblank for all openGL windows. (nvidia setting use to work for this, but did not anymore). (i'm using nvidia driver 195.36.24 with ubuntu 10.04, gem svn , pd 0.42.5 vanilla) any idea? alternatively, i'll be happy if i can have a Gem only solution to use pix_data without having to open a windows. thanks for any help Cyrille

In french only (désolé pour le même mail provenant de différentes listes !). Pour une meilleure mise en page, vous pouvez consulter le PDF joint à ce mail : /dev/art/#2 Rencontres, discussions et échanges entre artistes et développeurs utilisant les nouvelles technologies de programmation (arts numériques, hacking, performances, etc.). Le 14 novembre de 14h à 18h au BlackBoxe 17 rue de la Chapelle / 75018 Paris Metro ligne 12 / Station Marx Dormoy ou Porte de la Chapelle 14h / 16h : rencontres, discussions et échanges autour des arts numériques, de la performance, du hacking et du développement d'applications et d'installations. 16h / 16h30 : Pot/apéro 16h30 / 18h : performance + présentation de Ariadna Alsina et Alejandro Olarte Suite électronique pour violon et guitare v2 Alejandro et Ariadna sont musiciens, ils évoluent depuis plusieurs années dans la musique électroacoustique improvisée ou composée. Leur parcours les emmène à jouer en solo, en formation ou en collaboration avec des artistes issus d'autres disciplines. Pour cette performance, ils utilisent les sonorités d'un violon et d'une guitare augmentée pour représenter différents moments poétiques contrastés en faisant appel à plusieurs modes de jeu et à différents paradigmes de synthèse. Alejandro utilise le logiciel Super Collider pour le traitement de l’audio numérique en temps réel. Ariadna utilise Max/MSP avec les mêmes finalités. Alejandro Olarte: Formé en Colombie à l’Université Nationale et en France au Conservatoire National Supérieur, Alejandro chercheur en électroacoustique s’intéresse aux nouvelles lutheries, à l’improvisation, à l’interaction avec la danse et le théâtre et à la programmation. Ariadna Alsina: Après une première étape de formation comme violoniste, Ariadna se consacre depuis quelques années à la composition électroacoustique et mixte. Formée en Sonologie à l’École Supérieure de Musique de la Catalogne (Barcelona), elle s’intéresse aux objets sonores et au field-recording, qu’elle étudie et utilise pour ses créations artistiques et musicales. Prochain rendez-vous /dev/art/#3 le vendredi 19 novembre de 19h à 23h au BlackBoxe / 17 rue de la Chapelle / 75018 Paris ++ Jack _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Plugin~ arguments?
by Pierre Massat 14 Nov '10

14 Nov '10

Hi, I'm trying to use plugin~ for the first time and I'm stuck with the arguments. I wanted to try one of Steve Harris' plugins, tapeDelay. The plugin object loads it fine, and i get a bunch of control arguments when i send info to it. plugin~: constructed plugin "Tape Delay Simulation" successfully plugin~: plugin ports: audio 1/1 ctrl 10/0 plugin~: plugin active print: port in control Tape speed (inches/sec\\, 1=normal) 0 10 print: port in control Dry level (dB) -90 0 print: port in control Tap 1 distance (inches) 0 4 print: port in control Tap 1 level (dB) -90 0 print: port in control Tap 2 distance (inches) 0 4 print: port in control Tap 2 level (dB) -90 0 print: port in control Tap 3 distance (inches) 0 4 print: port in control Tap 3 level (dB) -90 0 print: port in control Tap 4 distance (inches) 0 4 print: port in control Tap 4 level (dB) -90 0 How do i control Tap 1 distance and Tap 1 level, for instance? More generally, I'm wondering if there is a rule to sort of translate the control arguments one gets in the console into the ones that are supposed to be used in messages. Cheers! Pierre

I was wondering if there are chaos or fractal equations number generators in pd? are there libraries for this? thanks R.

Not necessarily. Here's a simple FM patch where dynamic patching + data structures are used to visualize the signal data in the object chain itself. Once you get an interesting sound just click the "wires" to animate. It's a nice gimmick to trick people who don't like reading boring graph data into reading slightly less boring graph data.
