DSP loops
by Kim Taylor 02 Feb '07

02 Feb '07

Hi again all I'm having a bit of trouble putting my program together. I'm trying to implement a series of object blocks that form the synthesis framework, up until now everything's been ok. My problem is that on the top level of the program, I'm trying to connect the blocks together, but the configurations I desire involve feedback and result in "error: DSP loop detected (some tilde objects not scheduled)" I know send~ and receive~ can be used to overcome this, also throw~ and catch~ if I'm not mistaken. However I can't use these as they result in a fixed length time-delay. Normally this wouldn't matter so much, however as my synthesis technique relies almost fundamentally on very small delays (I'm implementing digital waveguide synthesis) this fixed delay time makes a huge difference. I'm not terribly experienced with Pd, has anyone been in a similar situation and care to share some experience? The only way I can think of overcoming the DSP loop problem is to use a delread~ and delwrite~ to complete the loop, setting the delay time to 0 and setting the level sampling block size to 1. However this seems a very roundabout way of doing it and not ideal, especially for the top level of the program! Cheers Kim

pd music

hi all, here's one track done with pd. it's a live recording, no edition, no mastering only adc~ -> some tweaking -> sfwrite~ i think it's a good example of what can be done with a cheap microphone, a bad guitar player (me) and pd. pat

gui redraw improved by holding down a random key
by hard off 02 Feb '07

02 Feb '07

on os x (10.39), and using pd 0.39.2 extended test 7, i'm getting this weird behaviour with the gui redraw. using a 20x20 pixel canvas as a cursor, and sending a [pos xy< message to change the cursor's position, the gui redraw is really blocky. BUT, if i hold down a key on the keyboard (any key seems to work), the gui redraws suddenly work really smoothly, and the 20x20 pixel canvas glides across the screen beautifully. the same thing happens with other gui objects (number boxes etc) too. attached is a patch that demonstates this. basically, the nice smooth action when i hold down a key is what i am after, but i don't want to have to hold down a key to do that.

mapping library examples
by Hans-Christoph Steiner 02 Feb '07

02 Feb '07

Cyrille and I started work on the mapping library a while back. I am wondering how many people have used some of the objects, and whether anyone would be willing to share a project where they used some of the objects. We are writing a paper about the progress of this library, so it would be nice to include some examples from the real world (i.e. outside what we do ;) .hc ------------------------------------------------------------------------ I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality and freedom for their spirits. - Martin Luther King, Jr.

Maximum Array Size (Again! was: [PD] array arrow test7)
by Kyle Klipowicz 01 Feb '07

01 Feb '07

Yes, this is a built-in limitation that can be modified in the source code. You could try writing a multi-array patch that uses seamless transitions or do as Andy suggested. Or you could modify the source, and recompile. References: http://lists.puredata.info/pipermail/pd-list/2003-04/011065.html (change source) http://lists.puredata.info/pipermail/pd-list/2003-04/011065.html (other discussion/caveats) Actually, I just found this message from Miller (April, 2003): 'Alternatively, just specify "-maxsize 1000000000" (or whatever) in the "read" message. Oops, still no usable help window for read/writesf... I've got that in the pipe for the next release.' (http://lists.puredata.info/pipermail/pd-list/2003-04/011069.html) Does anybody know if this was implemented? I have no way to test right now, but that would be great. ~Kyle On 1/31/07, padawan12 <padawan12(a)obiwannabe.co.uk> wrote: > Hi Echo! > > Tip: Don't use files longer than 2 mins :) > > Best way is to use [sfread~] instead. > > Andy > > On Wed, 31 Jan 2007 00:37:54 +0100 > Echo Ho <pidi(a)echoho.at> wrote: > > > hallo pidier > > i'm using Core 2 Duo mac book , and i don't know if the flowing > > problem is a os x (10.39 pd 0.39.2 extended test 7 or not: > > > > it doesn't load to array properly, when a sound file is longer than 2 > > Min. > > Message | read -resize -maxsize le+08 | > > > > error: soundfiler_read: truncated to 4000000 elements > > warning: array array1: clearing save-in-patch flag > > error: usage: read [flags] filename tablename... > > flags: -skip <n> -nframes <n> -resize -maxsize <n> ... > > -raw <headerbytes> <channels> <bytespersamp> <endian (b, l, or n)>. > > > > it works with a old extended version on G4... > > ;-( is there any tip for me? > > > > (\ /) > > [- . - ___earweego_sonicvision > > www.earweego.net > > > > > > > > > > > > _______________________________________________ > PD-list(a)iem.at mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list > -- http://theradioproject.com http://perhapsidid.blogspot.com (((())))(()()((((((((()())))()(((((((())()()())()))) (())))))(()))))))))))))(((((((((((()()))))))))((()))) ))(((((((((((())))())))))))))))))))__________ _____())))))(((((((((((((()))))))))))_______ ((((((())))))))))))((((((((000)))oOOOOOO

GL: invalid enumerant Gem, Ubuntu Edgy Eft
by Fanouris Moraitis 01 Feb '07

01 Feb '07

Hi all, I have the following error when I try to use pix_texture GL: invalid enumerant and also the texture is not loading. (For anyone that is interested in order to build pd under Ubuntu Edgy Eft with and Ati Mobility radeon X300 graphic card I had first to follow the directions in the following link http://wiki.cchtml.com/index.php/Ubuntu_Edgy_Installation_Guide ----it is important to use ati-driver-installer-8.33.6-x86.x86_64.run---- otherwise pd was crashing every time that I closed the gemwin) thanks, fanouris

Gemwin as Capture Driver to use in other software
by Peter Forde 31 Jan '07

31 Jan '07

Hello List, Is it possible to export the gemwin to other software in real-time. It seems to there are other softwares that can screen record and send this on such as Softcam, this uses up too much CPU and is highhly unstable. I just need another programme on the same machine to accept gem's output as an input.. Is it possible to turn it into a capture driver. If this was so the other software might recognise it. I need to be able to run Pd through another resolume so that in a live environment I can jump between one setup and the other without effecting the 2nd display's output. I am running on WinXP and Pd extended 38.2. Thanks a lot. _________________________________________________________________ Search for grocery stores. Find gratitude.

Dataflow Dictionary for Max and PD users...
by Nick Fox-Gieg 31 Jan '07

31 Jan '07

Hi, I'm a student at Sonology in The Hague, and I've started a "Dataflow Dictionary" wiki for Max and PD users--so you can look up an object in one program and find its equivalent in the other: www.fox-gieg.com/dictionary I was wondering if any list members would like to contribute to it? Thanks, Nick Fox-Gieg www.fox-gieg.com
