Re: [PD] Textfile vs. Lists vs. Arrays vs. ?
by Matteo Sisti Sette 27 Feb '10

Can't you simply load the files in exactly the same way you do now, but instead of doing it "on demand" (load a single file when the data it contains is needed), load all them at startup (into [textfile] objects, [list]s or arrays) and access them later?? -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Drawing a sound volume
by meino.cramer＠gmx.de 27 Feb '10

Hi, I want to control the sound volume of a couple of [osc~]'s and I want to draw it. I saw a "synth" (example/demo) where the amplitude of a wave was draw with the mouse in a little "scope" and I am curious to know whether is possible for regulating two hand full of osc?

GEM: gemwin perspec strange behavior
by Dario Pedrioli 26 Feb '10

26 Feb '10

Hi all, I'm triyng to play with perspec message. I notice that if I send a "normal" message to gemwin, everything works ok. But if I send the same message "compiled" from a message or a number box (or whatever), the center of the scene go to the left bottom point. OK: [perspec -2 2 -2 2 1 20< | [gemwin] KO: [2< | [perspec -$1 $1 -$1 $1 1 20< My sistem is a ubuntu 64bit - GEM: ver: 0.92.2 - nvidia GTX 260 with closed source drivers Someone noticed this? It's only on my machine? Thanks.

Textfile vs. Lists vs. Arrays vs. ?
by saint 26 Feb '10

26 Feb '10

Hi all, I've a pd system that involves the playing back of sequences and patterns. I store the pattern data in lots of separate text files which the system reads on the fly once the next pattern is called upon. My problem is that I get audio dropouts when changing some patterns, usually ones that call on a lot of text files. (I've put all the graphic-heavy stuff into a subpatch which remains closed during live playback as my initial feeling was the glitches were caused by graphical stuff as is usual with pd. But surely once in a subpatch and closed there's no overhead?) I suppose what I'm asking is, would I get better performance if I wasn't constantly calling upon text files on the hard disk? Say, saving the strings of numbers to lists or arrays? What would the best way to go about that if so? The reason I went for the text file route was that it was simple to re-order the sequences via a file manager and just generally easier to track down problems by inspecting the files rather than poking around in lists and arrays. But audio always has final say! Thanks in advance as always, John.

gemframebuffer and video OR multiple shaders
by Ben Baker-Smith 26 Feb '10

26 Feb '10

Hello, I'm working on porting Andrew Benson's optical flow glsl shaders over to PD. I've got the primary shader working, but need to send the output to the second shader. I figured that the best way to deal with this would be to use [gemframebuffer] to send the results of my first chain (including [pix_video] and the first shader) to a second chain to be processed with the second shader. My first problem is that I cannot seem to get [gemframebuffer] to work with [pix_video] or with [pix_film] for that matter. Is this the appropriate tool? Alternately, if someone knows how to use multiple shaders in the same render chain then I wouldn't have to use [gemframebuffer] at all. -Ben

PD FLOSS manual and help patch corrections
by Ben Baker-Smith 26 Feb '10

26 Feb '10

The last line on http://en.flossmanuals.net/PureData/GEMImagesMoviesAndVideo says to check out the [sig2pix~] object. The object is actually [pix_sig2pix~]. Separately, in the help patch for [pix_movie] it recommends using the same [colorspace RGBA( messages that work with [pix_film], but these messages return the error: "pix_movieDarwin: no method for 'colorspace'" I wasn't sure who to send these corrections to, but I figured whoever it was is probably on the list. Thanks! -Ben

GEM great framerate instability unless -noaudio
by Matteo Sisti Sette 26 Feb '10

26 Feb '10

Hi, On my Vista machine, I get an enormous instability of the framerate with Gem, even if dsp is switched off. However, if I run PD with the "-noaudio" flag, then the framerate is perfectly stable. Is it normal? When I say "enormous" I mean the time elapsed between a frame and the next one often goes below one millisecond and above 80ms, though an avarage of 40ms is always maintained. I am testing this with the attached patch, which has only a gemhead and a [realtime], so there's no actual processing of image or video. If anyone doubts that it can be just the time shown by [realtime] that is unreliable, note that if I run Pd with -noaudio the measured framerate actually _is_ much more stable (rarely below 37ms or above 43ms a frame) and also, I have tried it with a simple video (homer.avi) and I could note the jerky playing. Isn't it strange that turning off DSP does not change anything while running Pd with -noaudio does?? thanks m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com #N canvas 386 43 829 662 12; #X obj 94 82 gemhead; #X obj 94 114 t b b; #X obj 95 145 timer; #X obj 95 175 t b f; #X obj 98 241 /; #X msg 74 214 1000; #X floatatom 90 286 5 0 0 0 - - -; #X obj 293 72 gemhead; #X obj 293 104 t b b; #X obj 294 165 t b f; #X obj 297 231 /; #X msg 273 204 1000; #X floatatom 289 276 5 0 0 0 - - -; #X obj 498 151 gemwin; #X msg 537 63 destroy; #X msg 469 107 frame 25 \, create \, 1 \, frame 25; #X obj 294 135 realtime; #X floatatom 346 464 5 0 0 0 - - -; #X obj 661 270 t f b; #X obj 703 308 f; #X obj 679 400 +; #X obj 679 429 t f f; #X obj 714 354 * 0.99; #X obj 641 355 * 0.01; #X obj 696 460 t b f; #X obj 699 526 /; #X msg 675 499 1000; #X floatatom 691 571 5 0 0 0 - - -; #X floatatom 393 141 5 0 0 0 - - -; #X floatatom 477 335 5 0 0 0 - - -; #X floatatom 461 229 5 0 0 0 - - -; #X obj 366 220 moses 38; #X obj 419 277 moses 42; #X obj 326 430 moses 1; #X floatatom 386 337 5 0 0 0 - - -; #X connect 0 0 1 0; #X connect 1 0 2 0; #X connect 1 1 2 1; #X connect 2 0 3 0; #X connect 3 0 5 0; #X connect 3 1 4 1; #X connect 4 0 6 0; #X connect 5 0 4 0; #X connect 7 0 8 0; #X connect 8 0 16 0; #X connect 8 1 16 1; #X connect 9 0 11 0; #X connect 9 1 10 1; #X connect 9 1 18 0; #X connect 9 1 31 0; #X connect 10 0 12 0; #X connect 11 0 10 0; #X connect 14 0 13 0; #X connect 15 0 13 0; #X connect 16 0 9 0; #X connect 18 0 23 0; #X connect 18 1 19 0; #X connect 19 0 22 0; #X connect 20 0 21 0; #X connect 21 0 24 0; #X connect 21 1 19 1; #X connect 22 0 20 1; #X connect 23 0 20 0; #X connect 24 0 26 0; #X connect 24 1 25 1; #X connect 25 0 27 0; #X connect 26 0 25 0; #X connect 28 0 31 1; #X connect 30 0 32 1; #X connect 31 0 33 0; #X connect 31 1 32 0; #X connect 32 1 29 0; #X connect 33 0 17 0; #X connect 33 1 34 0;

LiWoLi raises the question of whether a practice of 'doing it together' (DIT) might be a more successful formula for developing free tools (FLOSS tools) for art & culture, learning & teaching. This also implies examining the motivation of active producers and making room for the aspect of "unpaid work". We are interested in contributions from groups that have realized projects 'successfully' or even 'less successfully' under the aspect of DIT in the field of Free and Open Source Software (FLOSS), open hardware, art & culture, learning & teaching, and want to make their 'tools and works' freely available and distribute them. * * * * * * * * * * * * * * * * * * * C a t e g o r i e s * * * * * * * * * * * * * * * * * * * Free and Open Source Tools # FLOSS (free/libre Open Source Software), Open Hardware tools.

Re: [PD] Strange bug in my patch
by Matteo Sisti Sette 26 Feb '10

26 Feb '10

I remember a bug in PD that if you create an instance of an abstraction (even by hand with ctrl+1) which contains dsp objects, its content doesn't start doing dsp processing until one more object is created (i.e. it is not added to the dsp chain when it should). If more than one object (abstraction instances) are created in one message-tree (i.e. triggered by one "bang"), _maybe_ all of them will be mute until the creation of any new object in a separate message tree. So a workaround in your case could be to programmatically create some "dummy" object after creating new "attack generators" and "pitch shifter". If the guess I have exposed in the second paragraph is correct, you will need at least a [delay 0] before the creation of the dummy object. However I think you could implement the whole thing without dynamically creating objects, by acurately arranging sends, receives (with and without tilde), throw~s, catch~s, statically creating a big number of "allocatable" objects (capable of playing one table now, another one later etc according to messages they receive), managing polyphony (maybe with [poly]) and of course, switch~ing off every object that is not playing... By the way I don't see anything inconvenient at all in what you asked :) ciao m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com
