[PD] [PD-announce] Pd @ KHM open days
Hi, the Academy of Media Arts Cologne (famous for this year's Linux Audio Conference) invites to its annual exhibition of student's works 16th to 19th July. There will be several Pd works again, some of them in the Klanglabor/Soundlab of the Academy, where Matthias Neuenhofer and myself will show pieces for the "16:9" speaker wall of Rumori/Teige. I cannot say much about Matthias' work, except that it's hauntingly beautiful! My piece is called "schusslig 1.7 beta" and consists of an unfinished abstract 2D bullet hell shoot'em'up game (Psyvariar meets Pong) written in Lua (the engine is ~500 lines of pure Lua, to be published later), graphics projected with Gem and sonified with Pd (with some game sounds courtesy of Obiwannabe) for you to survive.

[PD] Spell checking / existence of a word
Hi list, Has anybody developped a way to check the existence of a word in a given dictionnary? As a basis, I was looking at the aspell command line spell checking tool : http://aspell.net/ This is well suited, but it will need to use the shell object and I'm working under OSX, so I'm not sure of it's long term stability. Aspell can be used as a lib also, so i was wondering if anyone has ever developped an external based on it? Or has anyone some other ideas to do that?

[PD] [PD-announce] xxxxx pd workshop, berlin 29-31 august
You've got Pluggability. Pure Data in the Summer. 29-31 August, 2008 x/pickledfeet, Berlin Cost: 60 EUR (with HID sensor board), 50 EUR (without) Pure Data (Pd) presents the ultimate, free software environment for sheer audio, video and hardware pluggability, patching and piping. Pd provides the basis for all manner of audiovisual performance and trans-media installation, as well as satisfying the artistic quest for heady experimentation and improvisation. Yet few artists take the time to master a solid foundation in this graphical programming environment. The three day You've got pluggability workshop aims to provide a firm grounding and clear overview of the varied possibilities and paths offered by Pure Data. The first day will introduce Pd and quickly move on to how to create patches which create sounds and noises. The second day will look further at sound, particularly how to work with sampled audio, and will introduce the GEM library for working with live and recorded video. The third day will start with a look at the HID (Human Interface Device) system for getting sensor input into Pd, and venture into to using this input to control the audio and video patches which the participants have already created. No previous experience is necessary to take this workshop. This PD workshop will be roughly based on the Pure Data FLOSS Manual, written by Derek Holzer, Luka Princic, Adam Hyde and contributors from the PD community: http://flossmanuals.net/puredata Participants should bring their own laptop running GNU/Linux, Mac OS X or Windows, and with Pure Data Extended installed from: http://puredata.info/downloads They are also encouraged to bring their own ideas, sensors, USB game controllers, MIDI devices, microphones and video cameras. There will be an opportunity to buy the inexpensive x-HID sensor input board produced at Pickled Feet: http://1010.co.uk/avrhid.html Limited places!

Good thinking. The soloist is considering an upgrade to dual 10,000rpm SCSI drives -- a wise move given that mine is not be the only work in his repertoire requiring this level of computer performance. > Depending on the size of your files you > might bite the bullet and load them into tables...

This is *extremely* helpful. My previous approach involved the creation of unique abstractions for slightly modified instances.

Yup, you hit the "humanization" nail on the head. In certain sections of the piece, the computer builds complete musical gestures in real time. Depending on where it is in the score, the patch chooses the appropriate soundfile type and selects a specific file to trigger from a predetermined list wherein all files are similar, but never identical. (For obvious reasons, subtle volume and timbre changes are important when attempting to create an organic and richly varied performance environment). Randomizing start times between 6 and 56 ms seems to provide a natural "ensemble" feel in these instances. > It uses the same general method as the generic patch, but adds some > other goodies I would feel obligated to provide if I were giving the > abstraction to someone to use... but maybe it's way overkill for > personal use, or inside a patch where nobody's gonna see it.

Agreed. And I'm surprised there aren't others running into this problem with 8-channel 88.2/24 interactive patches like this. Of course, the 8-channel environment is useful for its ambisonic and other spatialization potential, and one solution that works well (for certain musical situations) is to spatialize monophonic soundfiles in real time. This is a great solution for reducing performance demand on the hard drive, but quickly becomes expensive in CPU cycles...

You could use Lua instead. It's like [shell] on steroids, if you
employ something like "io.popen" like this:
word = get_word_from_inlet()
cmd = "aspell -c " .. word
p = assert(io.popen(cmd))
result = p:read("*all")
Lua is trivial to build on OS-X. I just did it and I'm a complete OS-X
idiot. Here's how: You check out pdlua from goto10 subversion, edit
Makefile.static to let it find m_pd.h and build for OS-X ("PLATFORM =
macosx"), then do "make -f Makefile.static" while connected to the net
to let make download and build Lua for you and that's it. OS-X seems
to come with everything needed.

Our wiki used to be configured to only allow edits from logged in people, and all the vandalism was done through logged-in accounts. This why having a captcha for creating accounts might help as well. I see in the pdpedia 'recent changes' page that most of the spam is confined to two or three pages only, but it still messes up the history overview and makes it unreadable because of the tens of edits per day. Another question on the wiki: as a PD newcomer, one of the things I'm looking for is a more or less 'formal' description for each module's parameters, inputs and outputs. Most of the help pages have a short description and some example of a modules usage, but there does not seem to be a single structural way to describe each module. Would it be an idea to define some templates and examples for this purpose and ask the users of the wiki to use this to describe modules ?

You can split the difference, though, if you're using ambisonics, provided you're using B-format (wxyz). You can do all your ambisonic encoding and room simulation ahead of time, and then do the decoding in Pd. This way you'd only be reading four channels at a time, and the conversion from B-format to 8-channels is a fairly inexpensive set of multiplies and adds (a little more expensive if it's a "cube" rather than an "octagon" array, I think, since you could discard the "Z" harmonic with the octagon; in Pd a cube decode could be on the order of 24 +'s and as few as 4 *'s, most of the adds taking place in connections as the vectors are automatically added) -- you could easily make an abstraction to just put on the end right before you send it to [dac~], since b-format streams should mix linearly. I'm sure there are externals which could do this more efficiently than an abstraction (loathe as I am to use externals when there's an easy abstraction solution). In this setup, normalization becomes a little harder, though. It would also be useful if you later wanted to do some simple ambisonic "panning" of the solo marimba throughout the array - you'd have half the architecture you'd need for it, and B-format encoding of two or three streams is not gonna break the bank (unless you were doing some kind of full-on room simulation on top of it). The point is moot if you're using 2nd-order ambisonics, though, or if you've already spent a lot of time mixing and normalizing. As an aside, for pieces with different sections and patches with modularized processes, it might be a good idea to use the fade-in and fade-out in conjunction with [switch~] for expensive processes so that you're only burning cycles when the subpatch or abstraction for that section or process is being used -- but you have to be careful when there are delays involved since, iirc, delay lines maintain their state when they're shut off. You also have to insulate its [line~]'s and such from being triggered while it's off -- but it's easy enough to simply use [spigot]s to keep the patch from receiving any message at all.

Previously, it was really easy to delete all of the spams, so they weren't in the history anymore. But it seems my 'delete' tab has disappeared.

Great points all around. Of course I spent a great deal of time considering a range of similar approaches before I began work on the project. The commission dictated a high-resolution, 8-channel cube array, and the decision to avoid B-format came down to the fact that I wasn't happy with reverberation quality produced by the available csound ambisonic and spatialization algorithms. I knew I was giving up a certain amount of flexibility by directly rendering the files (using csound and a custom java-based preprocessor), but it seems I didn't quite anticipate the heavy demand the files would put on the playback system.

[PD] Free rotation in GEM
Hi, I have a question which I know myself is very vague, but may also be straight forward as well to anyone who has had the same problem. Trying to achieve free rotation *without* using [accumrotate], I have come across concepts such as multiplying matrixs and converting a matrix to "quarternion", "gimbal lock". At least my understanding so far is that, no combination of chaining [rotate] objects give me results I expect. How do you implement precise control of rotation matrixs? Is this exactly what people use GridFlow for? Or else, is the only option to make a patch which crunches yucky and complex matrix multiplication, then feed the results to [rotate] ? -- David Shimamoto ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

GridFlow does not support quaternions. I bet it's possible to add support for it using abstractions, but it wouldn't be fast.

Re: [PD] Free rotation in GEM
Hi Mathieu, I have not looked into GridFlow much, but I had the impression that its main concept was to add matrix manipulation features to Pd, all of its visual capabilities being just one of the many results of data you can manipulate with matrix. (or is the egg first?) Anyway, understanding its marvelous potentials, I have lately been stuck with Windows platforms. At least I got your point that utilizing GridFlow only for crunching numbers may work but not so efficient. What I am trying to do is rotate the vector axis of the object before applying [rotation]. This also calls for a method of summing the rotations when applying multiple times (and my current understanding is that this can only be done by multiplying the quaternion on each rotation) If there is no solution at the moment, perhaps Gem could use a few extra objects to ease advanced rotations? I feel like I am complaining about lack of features without pointing out what exactly is missing, when I should be blaming my lack of math skills. hmmm.. -- David Shimamoto > On Wed, 16 Jul 2008, PSPunch wrote: > >> Trying to achieve free rotation *without* using [accumrotate], I have >> come across concepts such as multiplying matrixs and converting a matrix >> to "quarternion" >> How do you implement precise control of rotation matrixs? >> Is this exactly what people use GridFlow for? > > If you tried GridFlow's bundled examples you'd see what I use GridFlow > for.

Hi Frank,
Did you have to install the XCode developer kit (or whatever it's
called) to do this? Or is there a built in compiler? What version of OSX
is it?
Thx for the help, sorry for the OT!
Chris.

Well, that's sort of it, if you use the name 'matrix' as taken from Jitter, or as taken from a plain linear algebra system that has been expanded to higher-order structures. I mean that in math, 'matrix' is limited to mean a grid of weights that make inputs correspond to outputs. the indices of that grid are 2-dimensional, with the rows representing inputs and the columns representing outputs or the other way around depending on which way you prefer it (or which way your software prefers it). The concept of 'matrix' as you would find in Jitter is something more generic, meaning that it's more about just storage than any particular operators... math is much more operator-oriented: matrices are matrices because of how you add and multiply them. Anyway, understanding its marvelous potentials, I have lately been stuck with Windows platforms. At least I got your point that utilizing GridFlow only for crunching numbers may work but not so efficient. No, you didn't get my point.

I don't recall anything in Pd that directly supports quaternions. Depending on what plugins you can use, you may or may not have a way to cook your own quaternions. I suspect that it's doable in GridFlow and less doable with other plugins, as it is usually the case, but I don't know.
