dynamic normalization
by Marco Donnarumma 11 Apr '10

11 Apr '10

Hi list, I've been playing around building a pd version of a basic virtual tenori. The result is good so far, but, when more than 5 or 6 notes are being played at the same time the sound is clipped. How can I dinamically normalize an audio output? Or am I pointing a wrong solution to the issue? Patch is attached. -- Marco Donnarumma aka TheSAD Independent New Media Arts Professional, Performer, Teacher - Edinburgh, UK PORTFOLIO: http://marcodonnarumma.com LAB: http://www.thesaddj.com | http://cntrl.sourceforge.net | http://www.flxer.net EVENT: http://www.liveperformersmeeting.net

[hid] button down press
by Tyler Leavitt 11 Apr '10

11 Apr '10

hello all... first off, wow! i never took a look at pd before i needed to control hydrogen via usb gamepad today, but wow... awesome program, sorry to have looked over it for so long. that being said, many thanks to the community & developers for making my computer audio tinkering 10x more fun! now... i just started using it today. my current flow for sending MIDI events via USB gamepad button downpresses is like this: [hid]---[route key]----[route btn_0]----[route 1]----[makenote] the second route object of course has more than one button (btn_0 through btn_11) with each output going through its own [route 1] (to only signal on the down press). needless to sat thats a lot of [route 1] objects... is there a way i can clean this code up? something along the lines of [route btn_0,1 btn_1,1 btn_2,1] etc.... hope i made myself clear... thanks much, tyler

Open Square Room 1.0
by Olivier Baudu 10 Apr '10

10 Apr '10

Hi... I'm happy to inform you that the 1.0 version of the Open Square Room is available here : http://yamatierea.org/papatchs/squareroom/OSR.htm It is a little audio and visual sequencer which can be used either with mouse, joysticks, wii remotes or MIDI keyboard by four persons simultaneously... I'm sorry that the web-site and the patch are actually only in french, but it's possible to test the basics functions without any french notion... Maybe it could be usefull to know that it was developed on a Ubuntu 8.04 with Pd-extended 0.41.4. It seems to work with other systems and configuration but I 've not tested by myslef. It's far from a bulletproof development but it works... (on my computer... :-p ). I hope you'll enjoyed 01ivier

Re: [PD] memento file retore crashes Pd
by colet.patrice＠free.fr 10 Apr '10

is there another project as sophisticated as memento but working on all platforms? ----- Mail Original ----- De: "weiss" <postmeister(a)weiss-archiv.de> À: pd-list(a)iem.at Envoyé: Mardi 6 Avril 2010 17h54:02 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: Re: [PD] memento file retore crashes Pd hi, i had the same problem with prepend while i changed from 0.41-4 to 0.42. pd starts with a message like this in the console: "class prepend renamed to prepend_aliased." in fact this means that the iem_prepend is used instead of the cyclone-prepend object. (i guess its cyclone on my system.) this doesnt crash pd, but memento isnt working because these objects are not compatible. as i figured out there is something different with the list-selector. didnt had time yet to really look at this problem. maybe later. (or frank will do the job????). martin forgot to say that iam on winxp and not using pd-extended. > Hello David, > > long ago under windows I've removed some crash with memento by replacing [prepend] with [list prepend]-[list trim], maybe it drives to some hints... > > > ----- Mail Original ----- > De: "David Schaffer" <schafferdavid(a)hotmail.com> > À: "pd list" <pd-list(a)iem.at> > Envoyé: Mardi 6 Avril 2010 10h10:50 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne > Objet: Re: [PD] memento file retore crashes Pd > > > > I forgot to mention: I'm on Win XP running the latest version of extended... > > > > > From: David Schaffer > Sent: Tuesday, April 06, 2010 10:07 AM > To: pd list > Subject: [PD] memento file retore crashes Pd > > > Hi there, > > I seeme to have a memento problem: I can easily save a configuration to file (.txt) but each time I try to restore the file, Pd crashes. I'm probably doing something wrong but I can't figure out what it is. I usually start by creating a .txt file somewhere and then use the "save" button on the careGUI object. That seems to work well since the file is created and has all the data into it. Then, when willing to restore, I push the file button, select the file I've created before andpuûsh the "restore" button, then booom. Am I doing someting wrong here? Can't find the goddam tutorial anymore... any help would be appreciated. > Thanks > > D.S > > http://www.flickr.com/photos/schafferdavid/ > http://audioblog.arteradio.com/David_Schaffer/ > > > > > > _______________________________________________ > Pd-list(a)iem.at mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list > > _______________________________________________ > Pd-list(a)iem.at mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list > > _______________________________________________ > Pd-list(a)iem.at mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _______________________________________________ Pd-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

gemmouse and pix_data
by jim 10 Apr '10

10 Apr '10

Hi, I'm trying to use gemmouse with pix_data to get the color values of pixels in an image under the mouse. gemmouse and pix_data use different co-ordinates? Is there a simple way to do this. It would be simpler if pix_draw put the image I was looking at into the bottom left of the gem window but it doesn't also because translateXYZ uses a different scale again from pix_data and gemmouse that complicates the matter. Anyway I'm sure there is a simple way to get the color values under the cursor. Any hints? Thanks, Jim

Re: [PD] default font for pdp_text and pdp_qtext
by Hans-Christoph Steiner 10 Apr '10

10 Apr '10

If you want to revert to that, I am fine with it. I never could get that helmet.ttf font working, that's why I switched it to Bitstream Vera. Since GNOME used that font as its default, it would be the most likely font to be already installed. .hc On Apr 9, 2010, at 2:11 PM, ydegoyon(a)gmail.com wrote: > > s'lam, > > yeh but these fonts, you introduced them ... > at irst, pidip was using helmet.ttf > that was coming with the source package .. > > massalama, > sevy > > Hans-Christoph Steiner wrote: >> So now that Bitstream Vera seems to have been purged from Debian and >> Ubuntu, I think that the PiDiP text objects should use a different >> font >> as the default.

cheaper bonk~ replacement ?
by tim vets 10 Apr '10

10 Apr '10

hello, I'm trying to optimize a patch to run it at the lowest possible latency. There is a subpatch with 6 bonk~ objects in it. This seems to be quite heavy on the cpu. As soon as I switch it on i get crackles. Is there a cheaper alternative to track attacks ? gr, Tim

new work for electronics, with pure data
by D McCarthy 10 Apr '10

10 Apr '10

Dear PD community, Last year, pd was used to perform one of my musical compositions; a sonata for electronics / just-tuned instrument. It was performed by the pianist and composer David Bremner at the National Concert Hall, Dublin. In case any of the members of this mailing list would like a copy of the score, and of the patch which was used for this electronics sonata, here are the download links: Score: http://www.mediafire.com/?myyzbdajc3m Patch: http://www.mediafire.com/?ib5tmtvym2z It's possible to listen to how it sounds from the myspace page http://www.myspace.com/davidernestmccarthymusic It's called "Sonáid" (which is Irish for Sonata) and this is an excerpt from the last movement of the work. In the score, rather than supply a patch, the algorithm is described verbally. If anyone has any criticism, or suggestions as to how this description could be improved, i.e. if there are any errors in there, or if you have any suggestions about how to make this patch more efficient, your pointing these out to me (by email, if you want) would be appreciated. If you would like to hear a full recording of the work or if you would like to have it performed at a concert, feel free to get in touch via this email address; (concert performance fees are from as little as 100 euro) It's very much hoped that people out there will try to perform this work, even privately. If you have good keyboard skills, or if you know someone who does, print it out and try it! To perform the work, a 60 key MIDI keyboard is needed. A special tuning system is used and the score dictates which notes are to be depressed, rather than which notes are sounding. Also, you'll need a fast latency time. Enjoy! And thanks to everyone who helped me get started with PD. Yours, Sincerely, David Ernest Mc Carthy.
