Pd and Edirol UA-25
by Ede Cameron 04 Jun '07

04 Jun '07

After reading on the list about Edirol UA-25 I went out and got one on run on Debian. I can get sound when running in standard mode or midi in advanced but can't get both. I read on the list that some- one is running both midi and sound. Problem is the UA-25 seems to force 24bit in advanced mode which Pd won't run at or is there a way to get around this. Debian Etch Power Book 1.5 Edirol UA-25?

Because it's cheaper to implement. If well done, it's also an intermediate step towards automatic threading. It's important to cut hard goals into easier goals, because it reduces required investment and gives quicker returns. Also, I wouldn't trust automatic threading to make use of the CPUs in the best possible way all of the time, *especially* for real-time. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC Canada

pix_record frames per second and again cpu-performance
by moritz 01 Jun '07

01 Jun '07

hello list two questions about pix_record: i render out some movieclips with pix_record. the Gem-render is 15 frames per second, but when i play it with mplayer it says it plays 20 frames per second. I have to force mplayer to play it 15 frames per second. can i give pix_record an argument that it should only record 15 fps? or is it just an mplayer affair? second question: i want to record different geos, so i have to pix_snap every frame and then go into pix_record. i think pix_snap is very cpu intensive, sometimes pd crashes. Is there another solution to record the Gemwindow that do not cost that much cpu power? thanx moritz

Thanks IOhannes So has anyone developed pd-plugin? it seems it only works on windows.... is there anyone else who developed other versions available of such plugin ? :D On May 31, 2007, at 7:35 PM, zmoelnig(a)iem.at wrote: > Quoting Miguel Cardoso <mcardoso(a)soopa.org>: > > >> Hi Frank! >> >> >>> http://www.iua.upf.edu/~malonso/pdplugin/ >>> >>> >> >> I had seen that one before, but it doesn't seem to work... on windows >> it installs de plugin, but when I try the test examples they don't >> work. >> anyone on the pdlist has used them? >> is the plugin still being developed? >> From the info you sent me it seems that pdplugin is just a >> javascript plugin to connect to pd server, rather than having pd >> running on the client-side. >> >> > > no its not. > the "barcelona" plugin is basicaly stripped down pd compiled into a > plugin (so it is exactly what you asked for) > > there are 2 other approaches: > - controlling a pd server via a plugin (javascript, java,....) or > directly via xml-rpc; there are several sites out there that use this > (afaik gollum.artefacte has a pd/pdp/pidip streaming server; pd-radio > was of the second type) > - controlling a full-fledged local installation of pd via a plugin > (iem's iARS took that road) > > mfg.asdr > IOhannes > > > > >

Re: [PD] what distinguishes a numeric symbol as an argument?
by Matteo Sisti Sette 01 Jun '07

01 Jun '07

Thanks a lot Frank, now I see it all quite clearly. I always thought that the two following conjectures were true: conjecture 1 - any given message output by any PD object can always be reproduced by writing it down literally in a message box conjecture 2 - a PD message is simply a human-readable string that you can always "see" by for example [print]ing it, or prepending a "set" and viewing it in a message box, and two messages that "appear" identical are identical. Now I see both conjectures are wrong (kinda disappointed since I loved them) but once I assume that, and thank to your explanation, everything is clear and coherent. A desired message can always be generated using a makefilename or something, and the difference between different cases can be detected - though all this in a less immediate way than I thought. Now that I think about it, a proper escaping mechanism for writing literals and spelling messages could allow both conjectures to become true without touching the message mechanism: an escape character such as § or whatever may force a number to be interpreted as a numeric symbol (or numeric symbol-selector). For example: [§123( [list 1 3 §123 foo bar( [symbol §123( Also, the [print] object may print out numeric symbols with the escape character Also, when dynamically setting (or updating) the content of a message box, the escape character may show up. Wouldn't it be desirable? What would the drawbacks be?

what distinguishes a numeric symbol as an argument?
by Matteo Sisti Sette 01 Jun '07

01 Jun '07

Hi list I understand that [symbol 43( is not the same as [43( as it is interpreted as a symbol, not a float. So I can send the message [symbol 43( to a symbol atom, or to any object that works with symbols, and it will be handled just as if it was [symbol dog(, right? However, when this symbol is inserted as an argument into a message, or packed into a list, what is it that distinguishes it from the number 43?? Let's make a practical example. I want to dynamically set the label of a canvas so that it shows a number. Suppose the receive symbol of the canvas is mycanvas_receive. (1) The following doesn't work: [label 43( (*) | [s mycanvas_receive] (2) Nor does this: [43( (or replace this with a number box) | [label $1( (*) | [s mycanvas_receive] (3) Nor this: [symbol 43( | [label $1( (*) | [s mycanvas_receive] (4) While this DOES work [43( (or replace this with a number box) | [makesymbol %d] | [label $1( (*) | [s mycanvas_receive] However, I can't see any difference between the output of the message box (*) in (4) and in (1-3). If I connect that message box to a [print] in any of the four examples above, the output is always "label 43". It seems that the message that is generated in example 4 is intrinsically but invisibly different from the previous 3 examples. I may deduce that each argument of a message has an associated type that somewhat depends on its "history" and cannot always be "seen"... which I don't like but may be an explanation. However, this does not explain the following: * Isn't the output of [makefilename] in example (4) just the same as [symbol 43( of example 3?? Then why doesn't example 3 work as well??? Also, consider this: (5) [label 43( | [unpack s f] and this (6) [symbol 43( | [label $1( (**) | [unpack s f] In example (5), the second outlet of unpack outputs float 43, which is (somewhat) coherent with the fact that example (1) didn't succeed to set the canvas label However, in example (6) unpack gives the error "unpack: type mismatch"... so I guess that the "$1" (i.e. the "43") in (**) is seen as a symbol, not a float....... but then, again: why didn't example (3) set the canvas label??? Anybody can help me to understand the underlying logic? Oh shit!!!!!!! Now I see that the following: [symbol 43( | [print] just outputs "symbol " while [43( | [makesymbol %d] | [print] outputs "symbol 43" as expected.... isn't it weird?????? Well... again, if anyone can help me to undertsand this, I'll be grateful Thank you m. -- Email.it, the professional e-mail, gratis per te: http://www.email.it/f Sponsor: Vacanza in Grecia: 7 giorni con trattamento all inclusive in albergo 4 stelle a soli 479 Euro Clicca qui: http://adv.email.it/cgi-bin/foclick.cgi?mid=6607&d=31-5

puredata evolution
by victor 01 Jun '07

01 Jun '07

Hi, I love pd :) but after many years from its creation, why some times it seem a casd's castle? http://teacher.scholastic.com/max/castle/img/cardcast.jpg After to read in that list the tipical question "pix_video don't work". I'm thinking about pd do you think that gem is a mature proyect for video creation? why not? why the evolution is slow? or simply why there are not a object for to save pretty videos in open formats? (same asks for pdp). Maybe the extended version is a valuable effort for to have a open platform for creatives. Then which is the sense of desiredata? ( https://devel.goto10.org/desiredata) summarizing: Which is the next future of PureData thanks

libjack-0.80.0.so.0
by Wolfgang Fulda 31 May '07

31 May '07

hello list, trying to run various pd-extended-versions (0.38 onto 0.40) under Linux (opensuse 10.2) I continually get: /"error while loading shared libraries: libjack-0.80.0.so.0: cannot/ /open shared object file: No such file or directory" I've browsed not only the pd-archives to see, that this is a common problem - Recently I had ///pd ///running fine under Linux-distribution kubuntu 6.06 - there was/// a "libjack0.100..."/// automatically installed by the package. But for other reasons I cannot use this distribution - so it would be nice to do it this way ... Are there probably ///any helpful ideas? Thank you! Wolfgang Fulda//

py/pyext missing in pd-extended

Hi all! Is py/pyext supposed to be included in pd-extended distribution?
