Re: [PD] Strange bug in my patch
The patch uses dynamic creation of objects and when dynamically creating signal-processing objects or abstractions, the dsp graph is not automatically recompiled (I hope I use the right words here). Recompilation of the graph can be forced by switching dsp off and on again. This is a known issue and has been discussed on the list. I can't recall if it is considered a feature or a bug, but probably it doesn't matter, since dynamic object creation is not officially supported).

If you run Pd in its 1st debug mode (pd -d 1), you'll see posts showing that creating or deleting an object quickly deactivates/reactivates DSP. So once you've loaded your sound file, set parameters and clicked Start, manually toggling DSP on, off, then on solves the problem as well. I didn't put in the time to see why DSP needed to be toggled in that way for your particular case though. Can you think of anything in your patch that might be linked to something like that? Just a guess (I haven't chased down all your sends and receives), but since this is isolated to cases where density equals 1, it seems pretty likely a patching logic bug is preventing a parameter from getting to a DSP object until after the Start button is pushed. Then, re-initializing DSP is refreshing that object's settings and all is well. Actually, when creating a tilde object or an abstraction, that processes signals, dynamically it's not taken into account for the currently used dsp graph. However, when you create the second instance (or any other tilde object), the first one is taken into account, but not the second. So even if it seems to work for densities 1, you actually hear only n-1 instances.

What my patch does is to load sound files and play them back at random intervals of time. If you load enough samples, it can create a very dense and granular sound texture, hence the name Texgen (texture generator). When I load a sample I can control the minimum and maximum interval between attacks, degree of tranposition (or pitch shift) and the density of the play back wich is just how many times the same sample is loaded so it can be played more times simultaneously. The problem I'm having is that when I load a sample with density = 1 the sound doesn't comes out and, that's the strange part, if a creat and object like, say, a bang button and delete it, the sound magicaly pops out of the loudspeakers. I know this is a little inconvenient thig to ask, but can someone help me? I don't know where else i could look for help. I attached the patch in this e-mail, and it can be also downloaded here: http://puredata.info/Members/caiobarros/texgen/ together with a sound for testing it.

Re: [PD] Strange bug in my patch
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 matteosistise...@gmail.com http://www.matteosistisette.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] Textfile vs. Lists vs. Arrays vs. ?
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. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] GEM great framerate instability unless -noaudio
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.

I solved this problem by copying the files in RAM, on a virtual disk, prior to playing from the patch. On Linux, I have a shell script that copies to /dev/shm then symlink to the folder where the patch resides, then start pd and it runs smoothly. As long as your files dont take up much space in memory, it's fine. Otherwise, they shouldn't sum up more than half the total RAM of your machine, otherwise it swaps.

Can someone update the [gemframebuffer] help patch to explain this anomaly? -Ben On Fri, Feb 26, 2010 at 12:37 PM, cyrille henry c...@chnry.net wrote: hello, you have to use frambuffer in order to chain multiple shader. there are example for this in the glsl section of Gem help. the most common problem with gemframbuffer is that you need to add a translateXYZ 0 0 -4 after the gemhead in order to have the same vision point than without the frambuffer.

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-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] Drawing a sound volume
Hi, I want to control the sound volume of a couple of [osc~]'s and I want to draw it.

Re: [PD] Strange bug in my patch
First of all, thank you for the support. This patch already gave me some headaches, but with this problem I just couldn't figure out what was going on. For what I understood, the problem is in Pd itself (I didn't understand if that is a pd bug or not though). But, Matteo, if the patch don't create objects dynamically It will always be limited by the number of allocable objects, isn't it? The other solution could work, and I'll probably do something like that since right now is much more important for me to get my piece done, although I can't help having a sensation of cheating (but this is of course just my compulsive neurosis). But why again dynamic object creation is not officially supported? It works fine in pd vanilla, wich was the one I used to build this patch, but it does have some problems. Isn't it usefull? Anyway, what you guys said was very very helpfull. And about the inconvenience, I was woried that I could not explain my problem in the subject and did not know how to search in the archive about this. So someone would have to look at my patch to understand what I was saying wich I find a little boring. Like all newbies, I was just worried of making a stupid question. Bye Caio Barros 2010/2/26 Matteo Sisti Sette matteosistise...@gmail.com when dynamically creating signal-processing objects or abstractions, the dsp graph is not automatically recompiled [...] I can't recall if it is considered a feature or a bug, but probably it doesn't matter, since dynamic object creation is not officially supported. [...] Actually, when creating a tilde object or an abstraction, that processes signals, dynamically it's not taken into account for the currently used dsp graph. However, when you create the second instance (or any other tilde object), the first one is taken into account, but not the second. This is _not_ only with dynamically created objects. It also happens with manually-created instances of abstractions containing dsp objects. See the attached patch: open test.pd, it contains a [catch~ audio] connected to the dac. Then create in it an instance of [myabs~ 500]: it contains an osc connected to a [throw~ audio], and $1 is used as the frequency. You will hear nothing. Then create a [myabs~ 700]: now you'll start to hear the previously created one, but not the second. And so on. So the bug also affects officially supported patching and it does matter, though only for live patching (everything works fine when you load a saved patch). When you know it it's not a major issue (or an issue at all), but until you realise it, it can be quite confusing when editing the patch and try to figure out what's going on... -- Matteo Sisti Sette matteosistise...@gmail.com http://www.matteosistisette.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Drawing a sound volume
Hey The best I can think of is: 3.audio.examples/D08.table.spectrum.pd On the help browserThat's a bank of oscillators which reference their volumes against an array, you might want something like that. Otherwise you could easily use a smaller array and just reference one point to each of your oscillators to it, or alternatively some vertical sliders side-by-side with sends to vary each of your partials. Hope this helps.

[PD] Fontsizes
Hi, I am still unsure, whether I have installed puredata correctly... Being on Gentoo-Linux, which I periodically update, I use a so called overlay especially made for gentoo to install pd-extended. When I start pd, the initial dialog (that one with the console) came up with a microscopic font size. Loading any patch also results in dialog, which came up with that too small font. Now I am able to change it to a bigger size, which often mess up the laout of that patch. I tried to set the font size globally in ~/.pdsettings, which does not work, though pd repports in startup flags my setting. I also can set to that fontsize by hand. When starting pd from the command line it reports: Pd version 0.41-4extended compiled 14:14:02 Feb 21 2010 port 5401 TCL_LIBRARY=/usr/lib/pd/tcl/library TK_LIBRARY=/usr/lib/pd/tk/library /usr/lib/pd/bin/pd-gui 5401 Waiting for connection request... ... connected Is there any way to increase the complete pd-display by a factor to make things readable?
