Re: [PD] Stupid arduino question
by Collin 18 Nov '10

18 Nov '10

This is a little late, so you may not want to get into it, but I once hacked firmata a little, so that it could read an encoder. I'll attach it.

Hi, I want to write a little patch in order to record 30seconds of audio, playing it back and then again recording and playing it back, and so on. Any examples/objects to suggest ? thx -- _.|| _. _ _ \/\/(_|||(_|(_ (/_

[PD-announce] /dev/art/#3 in Paris with Derek Holzer - Friday november, 19
by Jack 18 Nov '10

18 Nov '10

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/#3 Rencontres, discussions et échanges entre artistes et développeurs utilisant les nouvelles technologies de programmation (arts numériques, hacking, performances, etc.). Le vendredi 19 novembre / 19h-23h au BlackBoxe 17 rue de la Chapelle / 75018 Paris Metro ligne 12 / Station Marx Dormoy ou Porte de la Chapelle 19h / 21h : rencontres, discussions et échanges autour des arts numériques, de la performance, du hacking et du développement d'applications et d'installations. 21h / 21h30 : Pot/apéro 21h30 / 23h : performance + présentation de Derek Holzer : ToneWheels Installé à Berlin, Derek Holzer est un artiste américain passionné par la fabrication de ses propres machines analogiques, le field recording et les musiques expérimentales. Habitué des performances sonores, il viendra présenter son étonnant projet ToneWheels. ToneWheels, est une expérience de conversion d'image graphiques en sons, grâce à l'utilisation de disques transparents dont les motifs imprimés sont lus par des capteurs de lumières pour créer des textures sonores et visuelles. Performance totalement live et hardware analogique, ToneWheels cherche à révéler au public le processus de création et de construction de la performance elle-même. Derek Holzer is an American sound artist living in Berlin, whose current interests include DIY analog electronics, sound art, field recording and the meeting points of electroacoustic, noise, improv and extreme music. He has played live experimental sound, as well as taught workshops in noise art technology. He comes in Paris to present his project ToneWheels. ToneWheels is an experiment in converting graphical imagery to sound, inspired by some of the pioneering 20th Century electronic music inventions. Transparent tonewheels with repeating patterns are spun over light-sensitive electronic circuitry to produce sound and light pulsations and textures. This all-analog set is performed entirely live without the use of computers, using only overhead projectors as light source, performance interface and audience display. In this way, ToneWheels aims to open up the “black box” of electronic music and video by exposing the working processes of the performance for the audience to see. _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Re: [PD] lowest latency ARM board for Pd

I would be happy to know how you did install pd on your freerunner... I did tried to install from rep (using debian QText v28) and it doesn't start, PDa seems too old to install (need osso-esd wich is not available...) I had been able to install it before but not anymore :/ any hints ? tks Ol. ogeem.be okno.be > Subject: Re: [PD] lowest latency ARM board for Pd > To: cosmin O_O <horiacosmin(a)hotmail.com> > Cc: pd-list(a)iem.at > Message-ID: <4CDD2B53.9050002(a)iem.at> > Content-Type: text/plain; charset="iso-8859-1" > > On 11/12/2010 11:11 AM, cosmin O_O wrote: > >> I don't know if I done the good way of measurments, but I've only choose the "10ms" option on audio buffer and test some patches to see if the sound was correct. >> And it was (without cranks). >> >> > > ah i see. > the "10ms option" does not mean so much. it only affects the buffer Pd > uses internally; the audio-subsystem will add latency on top of that. > > the only reliable way to test latency is to measure it (by means of cables). > > which OS are you running on the FreeRunner?

Re: [PD] microtonal pitch glide using Risset's bell
by Collin 18 Nov '10

Hi Julian, To make this work you can modify the partial.pd abstraction to receive the frequency message as a signal. e.g. replace this bit: [r frequency] | | [* ] | [+ $4] | with this: [r~ frequency] | | [*~ ] | [+~ $4] | then send something like [72, 72.4 15( | [line~] | [mtof~] | [s~ frequency] Does that make sense, dad? congratulations, Collin On Nov 17, 2010, at 2:41 AM, pd-list-request(a)iem.at wrote: > Message: 2 > Date: Wed, 17 Nov 2010 10:37:35 +0000 > From: J bz <jbeezez(a)gmail.com> > Subject: [PD] microtonal pitch glide using Risset's bell > To: pd-list(a)iem.at > Message-ID: > <AANLkTim8hSjVmfN3hO5RynrtqYx=rz1qYLx9G-qSdRXJ(a)mail.gmail.com> > Content-Type: text/plain; charset="iso-8859-1" > > Dear List, > > I have a basic rip of the Risset Bell from the tutorial patches and > I can't > seem to figure out how to make the overall pitch glide from one > microtone to > another from midi number 72 to 72.4 over 15ms, for example? > > A month old baby and a looming deadline has turned my brain into > mush... > > Patch is attached (it's for an upcoming performance of John Cage's > 'Ryoanji'). > > All good wishes, > > Julian

Which Linux distribution are you using?
by Pierre Massat 18 Nov '10

18 Nov '10

Hi all! I have realized lately that Fedora/PlanetCCRMA may not be the best linux rt distro out there in terms of updates for Pd. So I wanted to conduct a survey among pd-list members to know who is using what. It seems like Ubuntu Studio is the distro that's most frequently updated. Too bed because the last time i tried to install it on my laptop it didn't work... Any advice would be appreciated. I need a rt kernel, of course... Pierre

Re: [PD] microtonal pitch glide using Risset's bell
by Andrew Faraday 17 Nov '10

Hey Jb I've just had a look and fixed if for you. It was one of the classic Pd Gotchas. Basically the frequency you wanted to change (from the outside) was going direct from a recieve to the cool right inlet of a [*] object. Meaning it would require an extra bang or a change in the argument number to take effect. Just swapped the wires into this object round and it works fine. Oh, the [pd line] is just my testing system, running up and down from midi 40 to 100, obviously you'll want to change this to work with your patch.

Hi, for sure everyone noticed already, but since puredata.info isn't online for some days now, I just wanted to ask if you know when it will be back again.

microtonal pitch glide using Risset's bell
by J bz 17 Nov '10

Dear List, I have a basic rip of the Risset Bell from the tutorial patches and I can't seem to figure out how to make the overall pitch glide from one microtone to another from midi number 72 to 72.4 over 15ms, for example? A month old baby and a looming deadline has turned my brain into mush... Patch is attached (it's for an upcoming performance of John Cage's 'Ryoanji'). All good wishes, Julian

curve3d alternative
by mami music 17 Nov '10

17 Nov '10

Hi everyone I need to create a grid in GEM in which i can control each node independently. I tried using [curve3d] but the transposition of one node affects its neighbors (as this object is intended to work). What i need is something that would be capable of creating some sort of histogram, where each node can take a Z value independently. I guess that if i use [curve] and use the resolution equal to the number of nodes i could achieve the effect, but i would be dealing with many independent entinties and would have to duplicate them to achieve the orthogonality of the mesh. Any suggesions? Thanks D
