Fwd: [PD] Gem questions

Why doesnt the email list set the reply field to be the list, and not the receiver. Am I the only one with a short enough attention span to constantly fuck that up? :) ------------------ Hi. Thanks for the feedback, I will look into GLdefine object, and any GEMGl_ objects (which I understand should all be GEM prepended to any normal openGL calls (ie the object name)?) Do you guys (or anyone) have any simple example patches using the gemgl_*/gemdefine objects? Where do they fit in the em chain, etc? Just curious so I can get started. Peace!

The arguments of #for are organised the other way around, so that it's instead: [#for (-4 -1 -1 -1 0 0) (5 2 2 2 1 1) (1 1 1 1 1 1)] With all the start-indices first, all the end-indices next (the ends are always excluded), and then the index-steps (all ones because you want them to increment one by one) .-----------------------------------------------------------------. / The Diagram is the Program (TM) ,--------------------------------} {----------------------------------" http://artengine.ca/matju / `-----------------------------------------------------------------'

Gem questions
by vade 04 Apr '05

04 Apr '05

Hello list. 2 quick questions. 1) Is there a way to enable an alpha channel for the [color ( message to gemwin? I ask because jitters [erase_color] attribute with an alpha between 0 and 1 allows for interesting trailing effects when geometry is moved, and leaves a gradated trail behind it. Quite nice. 2) Is there a way to change blend mode attributes for gemhead objects? Ie force a renderchain to render with one of the 7 source and 7 alpha blending modes that should be available? forgive me if this is in the docs somewhere, but I havent seen it mentioned. Thanks, - { v a d e } / /

oh I hate this kind of Webmail I'll put the file filterplot_biquad.pd in here as text, so that one can get it by pd-list archives, too. (or is there an easy way to convert the I04gY2FudmFzIDE3IDAgMTE1MCA3OTQgMTI7DQojWCBv stuff to a nice pd patch?) sorry for mailing twice Bernhard #N canvas 17 0 1150 794 12; #X obj 56 417 bang~; #X obj 56 449 dirac~;

PureData Montreal Users Group
by Mathieu Bouchard 04 Apr '05

04 Apr '05

Hi, this is just to say that the PureData Montréal Users Group is still alive after 15 months. We have had our 9th meeting last Saturday, and the attendance was 11, 8 of which were from the city of Montréal and 3 from the city of Gatineau. The 8th meeting had 16 people. The mailing list is about to reach 100 people, and here is the url for subscribing: http://ns.artengine.ca/mailman/listinfo/pdmtl The mailing-list is used for announcements of users group meetings, puredata shows, shows of other dataflow software (sometimes), some other interesting announcements in interactive arts, and occasionally it's also used for user questions about puredata. Pasted below are the announcements for the 8th and 9th meetings, so that you can see the kinds of things we are doing. Sorry, I won't translate, but if you don't read French, at least you will be able to read most important keywords. :-) The tenth meeting will be in early May, and if everything goes well, it will be at Vidéographe-PARC. Vidéographe is an artist-run centre specialized in video production and distribution, established 1972. The PARC is the media art lab branch of Vidéographe, which started getting more into PureData recently, and where we have had our 4th meeting. ------------------8<--------cut-here--------8<------------------ Quoi: PureData Montréal Users Group meeting #9 Quand: 2005 avril 02, 13:00 Où: Studio de Marc Fournel Durocher 6545, 4ième étage Admission: 0.00$ (dons acceptés) Maximum 30 personnes Langue: Français avec un peu d'anglais, comme d'habitude. 13:00-13:30 : Intro 13:30-15:00 : MARC FOURNEL & THOMAS OUELLET FREDERICKS Tontauben une installation audio interactive avec système de positionnement local captant le déplacement de certains objets dans la pièce. note: cette présentation avait été prévue pour la réunion précédente, mais a été reportée pour cause de problèmes techniques. Cette version-ci sera plus étoffée puisque l'équipement complet est déjà dans le local de la réunion. Durant la présentation, il y aura des éléments performatifs ainsi que la participation de l'auditoire. 15:15-15:45 : MICHAL SETA Introduction to RRadical and LADSPA (and possibly a performance) 15:45-16:15 : THOMAS OUELLET FREDERICKS P5GLOVE (http://www.p5glove.com/) : Suite à des discussions sur la pd-list, je me suis procuré un p5glove. Je vais présenter cette technologie fort abordable ainsi que les moyens de l'intégrer à Pure Data (midi). 16:15-16:?? : THOMAS OUELLET FREDERICKS Data-art : Présentation de Data-art : Développement et objectifs. Data-art est un site de ressources en fraçais pour les artistes utilisant Pure Data. Data-art a été initié par Jean Décarie et financé par le CIAM. ________________________________________ PS: Comment venir par métro: trajet à partir du métro Beaubien: ouest sur BeaubienE nord sur StLaurent ouest sur BeaubienO nord sur Durocher trajet à partir du métro Parc: sud sur Parc (bus 80) ouest sur BeaubienO nord sur Durocher ------------------8<--------cut-here--------8<------------------ > Quoi: PureData Montréal Users Group meeting #8 > Quand: 2005 fév 26, 13:00 > Endroit: Saint-Denis 8257 (métro Jarry) > > Admission: > 0.00$ (dons acceptés) > Maximum 20 personnes > RÉSERVATION REQUISE (mailto:matju@artengine.ca; tel:383.3801) > > Langue: Français avec un peu d'anglais, comme d'habitude.

Marc Fournel: Tontauben une installation audio interactive avec système de positionnement local captant le déplacement de certains objets dans la pièce. (POSTPONED TO MEETING #9) 3. Patrick Lacombe (20-30 min): Une présentation de la chose audio que je build depuis quelques mois. C'est plein de patchs que j'ai trouvées sur le web (mailing-list, em411) qui sont réunies dans une patch qui s'occupe des volumes (limiter), des effets et qui ouvre les possibilités de faire de la musique expérimentale en temps-réel. J'aimerais réitérer ma proposition de faire une patch audio commune à pdmtl. durée 20/30 minutes. 4. Patrick Lacombe (court): pix m'a aidé à installer qa3pd, je pourrais montrer/parler pendant quelques minutes des possibilités de ce bridge (de quake3 à pd via netreceive). 5. Julien Keable et Jean-Sébastien Sénécal (30-45 min): "DRONE -- Les arts numériques pour la masse" Drone est un logiciel libre pour le traitement audio et vidéo en temps réel. Basé sur une structure en flot de données très similaire à PureData, Drone s'en distingue également sur plusieurs aspects. Cet exposé présentera d'abord l'historique du logiciel et du collectif qui l'entoure. Nous tenterons d'illustrer notre philosophie de développement, les difficultés auxquelles nous avons fait face et comment nous les avons surmontées. Nous compléterons par une démonstration du logiciel et par une discussion sur les similarités et les différences avec PureData en tentant d'ouvrir la voie à d'éventuelles collaborations. .-----------------------------------------------------------------. / The Diagram is the Program (TM) ,--------------------------------} {----------------------------------" http://artengine.ca/matju / `-----------------------------------------------------------------'

It s using the [fft~] of the impulse response of the filter, you can see the impulse response in the (resizable) array response. (The impulse response is what you were drawing in using [FIR~].) You can also play around with [biquad~] by setting the pole and zero positions of the biquad filter. (The adjusted zeros and poles both have an conjugate complex counterpart, i.e. the same value but with negative imaginary part.) HTH a bit Bernhard

pd debian package

hi guenther, hi list ... there are 2 annoying things happening with the pd package on debian: first, this is the memory leak that kills pd after a certain time: ==3726== 2050332 (1118472 direct, 931860 indirect) bytes in 46603 blocks are def initely lost in loss record 157 of 158 ==3726== at 0x1B904F75: calloc (vg_replace_malloc.c:175) ==3726== by 0x1B99FEDA: snd_midi_event_new (in /usr/lib/libasound.so.2.0.0) ==3726== by 0x80E8BBF: sys_poll_midi (in /usr/bin/pd) ==3726== second: starting with pd with -nomidi segfaults: [Switching to Thread 1076206016 (LWP 3770)] 0x400a62fe in snd_seq_get_client_info () from /usr/lib/libasound.so.2 (gdb) where #0 0x400a62fe in snd_seq_get_client_info () from /usr/lib/libasound.so.2 #1 0x080e886d in sys_do_open_midi () versions: pd: 0.38.4+amidi-1 libasound: 1.0.8-3 thanks ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

Re: [PD] Prime limit sliders
by Chuckk Hubbard 04 Apr '05

04 Apr '05

Hi, Mathieu. This sounds pretty intense, but maybe because I haven't gotten that far into Pd. That is dead on, though, to just have the slider go smoothly decimal and use the closest value in the table. That would work perfectly. I never considered that the grid would have to be double the exponents + 1. Never occured to me. Wow, I kind of understand this. Might it be less involved to have the possible values of the sliders determined by a prime to the power of -1 to 1 (maybe throwing 9 in as a "prime"), but this ratio being multiplied by all of the last 7 or 8 pitches, and the results being the available pitches? In that case, I can't imagine what would happen if you changed a note in the middle of the sequence. But this would allow endless modulation in small, rational steps.

Prime limit sliders
by Chuckk Hubbard 04 Apr '05

I want to create a microtonal step sequencer. I'm wondering if this is possible: I want to be able to set the prime limits separately, like how many powers of each prime number up to 17 or so will be allowed as values. Then, the pitch slider will give only values that are fractions where the numerator and denominator are multiples of those primes. For instance, with the prime limits: 3-4 5-1 7-1 11-1 13-0 17-0 I would get values like: 11/8 3/2 8/5 5/3 27/16 12/7 7/4 16/9 9/5 Or maybe they could be displayed as stuff like 5x7/3x3x13 or whatnot. 2 would be assumed infinite, at least for now. One option that would be okay would be numerator and denominator displayed in separate boxes, if they could be controlled by one slider. I'm thinking a/b = c, and the value of c determines the pitch value, but a and b are displayed. The trouble is that every possible value of a/b would have to be known to put them in order. Is it possible? Thanks. -Chuckk -- "Some people got attitude, Backed up with attitude." -G. Love
