random movieclips with pdp_qt
by Riku Mäkinen 24 Aug '07

24 Aug '07

Hi, I can´t figure out how to open random movieclips with pdp_qt. When I send open $1/1.mov to pdp_qt it works fine and Pd opens the clip but how do I make second number of the message variable? (Something like open $1/$2.mov??) By the way I don´t really understand whole dollarsign-stuff.. With GEM I managed to do wellworking videoclip-randomplayer but I need to use some blur-effects of pdp for videoinstallation. There´s patch attached with the mail for some kind person to look at. best wishes, riku

The name $0 has the same scope of the names $1,$2, in the sense that: in any two places where two $0's would have the same value, two $1's would have the same value. Both are values that are generated at the time of creating the object (semantically I mean, I don't know if it is so in implementation and it is irrelevant) and don't change later. So it is not *so* inconsistent. Making $0 mean in a message the same it means in an object box, would make it *a lot* more inconsistent with $1,$2 in messages than $0 is with $1,$2 in object boxes. $1,$2... in messages are evaluated at the time the message box receives its input and generates its output; they are arguments of the message it receives. The "natural" object-counterpart of $0 would be a number that is unique to that particular message event (not message box) or message tree, though that would be of little or no use..... or wouldn't it? Also, consider the following goal: (*) give direct access to (implicit and explicit) creation arguments ($n) of the patch within a message Making $0 mean the same in a message box than outside it would address goal (*) only for the particular case of $0 and not for n>0, and I personally think this isn't an elegant approach. Also, any future attempt to address (*) for n>0, would probably result more difficult or have to be more inconsistend if the $0 case has been treated this way. I am personally strongly against implementing $0 in messages meaning the same as $0 outside them. It would introduce further inconsistence. If there actually is some inconsistence now, it is not a good reason imho to deliberately introduce more inconsistence. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Clicca qui: http://adv.email.it/cgi-bin/foclick.cgi?mid=6905&d=17-8

SMP Questions
by Matthew Polashek 23 Aug '07

23 Aug '07

Hi! Anyone know if PD is aided by SMP? I'm throwing together a new box in which I will install UbuntuStudio with the intention of using it as a live processing rig for live performance using PD. I'm interested in discovering whether it makes more sense to get a Core 2 Quad processor that runs with a bus speed of 1066 or a Core 2 Duo processor that runs with a bus speed of 1333. The idea is to reduce latency as much as possible. I'll get I/O via a RME 9652 and a couple Behringer ADA8000 units. Also, any thoughts on how ram speed plays into this equation? I'm looking at the Intel dg33fb board. Matthew Polashek matt(a)tinysongs.com www.tinysongs.com www.JandMJazz.com www.BLDBand.com

pd-gui waiting for connection request
by Matthias Blau 23 Aug '07

23 Aug '07

Hi list, after playing around with debian etch I can't get pd to pop up the gui anymore, pd -verbose just tells me it is using port 5400 and "Waiting for connection request..." and doesn't do anything. Googling around told me that there were/are other people having the same problem, but no suggestions for solutions so far. So i thought this list would be the right place to ask for advice. Any help? Thanks, Matthias

How can I mirror the canvas into a GEM window?
by joan 22 Aug '07

22 Aug '07

Hello, I'm starting to use puredata recently, and I'd like to know if there exists a simple way to put a real-time mirror of the canvas into a gem window, for example, to overlay the images I want to display with the puredata objects I use to generate them. Someone told me in max/msp there is an object called DesktopJitter that does that. In theory it should be easy, as both the GEM windows and the canvas are displayed by the same graphic card. However, someone told me the graphic objects are managed in a weird way in PD so -even if it's perhaps not related-, I am not sure I can find how to do it. And I have no idea of how the canvas is managed in PD. Some advice? Thanks, Joan PS. Unfortunately, I'm mainly working on Windows. However, if a solution exists only for mac or linux, I'll be happy to hear about it.

Excerpt from a PD class in 2010 (when $0 for message boxes has been implemented meaning the same as a $0 in an object box): STUDENT: So a $ sign in an object means a creation argument of the abstraction instance. But I've seen some $0's around... I thought $1 was the first creation argument. TEACHER: Yes, $1 is the first creation argument. $0 is a sort of special implicit creation argument which is a number assigned by PD unique to a patch. It is especially useful as a prefix for assigning "local" names to sends, receives, values, etc. STUDENT: Oh, I see. Now, I have tried using $1 and $2 in this message box, but I get confusing and unexpected results. TEACHER: (looks at the student's patch) That's because a dollar sign in a message box is not the same as a dollar sign in an object box. In a message box, $1 and $2 are the first and second argument of the message that is input to the message box. They may change every time a message is received. STUDENT: (showing another patch) Oh. So what does the $0 mean in this message box? TEACHER: Well, $0 in a message box *is* the same as in an object box. So you can access the $0 of the patch from within a message without making a clump around the message box. STUDENT: And what if I need to access the $1 or $2 of the patch from within a message? TEACHER: You have to make a clump around the message box. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: La soluzione per vendere o coprare qualcosa, la trovi su Email.it Annunci!

Re: [PD] shell script for ieee1394 on debian
by Tim Boykett 21 Aug '07

Hi Olivier, I seem to be having the problem again that some paranoid program is snipping off the dv.sh script because it might contain a virus! Did you mean the following script: mkdir -p /dev/ieee1394/dv/host0/PAL mknod -m 666 /dev/ieee1394/dv/host0/PAL/in c 171 34 mknod -m 666 /dev/ieee1394/dv/host0/PAL/out c 171 35 I copied this from the article that you linked below. If it is this, then Hurrah! it works. Do you have any idea why it is necessary to create these nodes, while Kino seems to find the devices without any trouble? It would be nice if this "just worked" "out of the box" on linux. Cheers, tim On 16/08/2007, at 10:12 AM, Olivier Heinry wrote: > WARNING: This e-mail has been altered by MIMEDefang.

VST for audio network
by João Miguel Pais 21 Aug '07

21 Aug '07

Hi, can anyone recomend a good VST plugin to send audio data through a local network, with good audio quality and low latency? Something that could be used with PD/Max-MSP (or basically any program who uses VSTs) in both XP and OSX, for an improvising laptop trio connected through a local network (router, not internet). I was looking at tubePlug - http://t-u-b-e.de/iplug.htm -, but there seems to be a standard 1sec (!) latency, even when opening both server and sender in the same computer. But besides that, this plug-in seems to have potencial. After contacting the author, he seemed interested in adding a variable latency parameter, but who knows when it will be implemented.
