Re: [PD] purepd atan2~ without expr/externals?
A way to attack it might be to find a continued fraction form like I did for tanh, about 4 or 5 terms was an adequate approximation. Hi, I'd like to use a signal [atan2~] in a Pd without externals nor [expr~] (i.e. inn RjDj).

Re: [PD] a story for Lists
This has always confused me, and even in my book I took a simplified approach to explaining lists. It is definitely worth working hard on this passage to choose clear and agreed words. a. Hallo, Hans-Christoph Steiner hat gesagt: // Hans-Christoph Steiner wrote: In keeping with the FLOSSmanuals methodology, we need a story to tell when introducing lists. I have the intro done, but now we need a story (i.e. developing an example program). I was thinking that a story involving only lists of numbers would be a good place to start. Sorry for not being able to contribute much currently (I'm moving houses) but I think a neat usecase for lists and meta messages (which are important to explain in that context as well) could be the ADSR envelope. Its parameters are a list of four (rsp. five with level) numbers. It can be very useful to be able to set a ADSR by passing complete lists. It can also be useful to set the parameters with meta-messages like A 20, D 30, S 76, R 300. Here's an implementation of an adsr that relies heavily on list-processing: http://footils.org/cms/weblog/2009/mar/21/adsr-envelopes-pd/ I would also strongly recommend to use a consistent terminology for lists that are not lists in the Pd sense: I would call them meta-messages just like Miller does, and if there's ambiguity the manual should call proper lists list-messages. In the Lists-chapter at http://en.flossmanuals.net/bin/view/PureData/Lists it may be useful to also use a non-commutative math object like [/] or [-] with list-input, because that's a useful trick to quickly get the inverse or complement of a number: [1 $1(---[/ ] Ciao -- Frank ___ 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] sound for blender apricot opensource game
I agree, and have more or less reached the stage where I could sound design an entire small film in Pd. Time is obviously a factor and if I were to do this it would really need a few other volunteers who were enthusiastic about it (sound design for such a feature could be a challenging project) Anyway, what stuck me was something (I think it was) Dan James said about Elephants Dream; - that despite the visuals being entirely FOSS the soundtrack had to employ Windows/non-free components because of a lack of reliable sound tools and skills. That reflects on us all rather badly of course. Let's say the Blender Apricot team were amenable to the idea and we could reach a concensus to using the new film as a vehicle to showcase Pd, would anybody else like to be involved in a sound design team using Pd 0.40 on 64Studio with a Python interface to the event stream? Or maybe Lua would be our timeline/event glue. I am of course open to other suggestions or to supporting another team with radically different ideas, but this is how it would work best for me. andy This sounds like a great opportunity for Pd, especially considering that Pd is the sound engine in the game Spore. .hc On Feb 1, 2008, at 7:09 PM, olme wrote: seeing this: http://apricot.blender.org/?p=59 , I had the idea that somebody could do it efficiently with generated sound dezign (like brilliantly discussed earlier here by andy - obiwannabe.co.uk ) In short : Blender Instituut search for a sound designer for the upcoming opensource game codenamed apricot.

Re: [PD] [ot][hardware] mini-itx
I love these things. The original reason for trying them was to have a silent (no fan) system. The 533/600MHz Edens are wonderful for installations and really cheap now. Best all rounder is the 1GHz Nehemia imo, I've gigged with one instead of a laptop and they are very reliable. You can run them fanless with careful heatsinking. All the M series are good, many flavours to choose from. The downside of USB1 types is slow boot time. The most powerful mini-itx form are the Celerons, built a couple of custom small form factor servers for people using these and last time I checked they had almost a year of uptime. On the bad side...some of the advanced features like hardware mpeg decompression don't work without Windows. Also don't buy anything from mini-itx.com though. I had one DOA and after I shipped it back they never sent the goods. They don't answer any correspondence.

Re: [PD] Looping samples with tabread4~
You're on exactly the right track and thinking all the right things. An important value to grab is the length of the sample (in samples) which you can get from [soundfiler]. Multiply your [phasor~] by the magnitude of the loop and add it to an offset in samples and that should be the table index you need. (please excuse awful html formatting , using webmailer ) andy Hi! Maybe I haven’t looked hard enough but I just haven’t been able to find any examples on building a sample playback engine that will allow for sample-start, loop-start and loop-end positions to be set. The question is what would be the easiest way to achieve this. I have been thinking about ways to achieve the sample clock driver but since I’m new to PD perhaps my thinking is too complex. My ideas have been: Should I try generating the sample clock driver using two phasor~ objects where one phasor~ handles sample-start ‘til loop-end and let the other one (loop-start ‘til loop-end) kick in once the first one has completed it’s first and single run. Perhaps using a vline~ for the first part instead of a phasor~ Simply using one phasor~ object and offsetting the start value of it’s second cycle to the loop-start position Simply using a vline~ object and “loop it” with a different start position the second time onwards. I suppose I would have to use the samphold~ object to make the shift between phasor~ or vline~ or just to offset the start position of a phasors~ second cycle. Any ideas or examples on how to best achieve this would be more than welcome. /Mikael ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Also, if the patch is to be linked from a web page (link to a single Pd file) then most browsers can associate the filetype and open Pd. This doesn't work if the file is tarred or zipped so just make it a tar file isn't really a satisfactory solution. The more robust way is to have everything embedded inside the patch and have Pd handle it.

Re: [PD] Cymatics/Chladni figures simulation
Amazing idea for a project Carl. The way I see it you have two routes. 1) Do a full finite element physical model of a circular lamina and measure the amplitude at many points on the surface. The sand falls into minima nodes iirc . 2) Cheat. Create the visuals by mapping the known standing waves of various modes but missing out the actually building a physical model part. The latter is more feasible for a real-time simulation, but possibly more difficult than using the model. You'll need a much better mathematician than me to help you work out the mapping. In the worst case you could sample the data, do a frequency sweep and fit an equation to each standing pattern which is indexed by the frequency input from your voice. Hope that helps.

Thanks for sharing that I enjoyed it. Some lovely sounds. I wasn't much taken with Mr quacky at the start :), but once that was over I enjoyed the textures and decelerating rythms. I don't hear how the maths works, but it works for me. If you like textures based on dilating/warping events the attached patches might inspire some ideas. The first is for an elastic object that gives up a little kinetic energy on each bounce, the other is a fragmentation model for something falling apart that uses bifurcation. They're for bouncing balls and breaking glass for me, but I think they have compositional uses if you twist em a bit.

Obviously the decimal expansion of pi does have some order, but you might want to call it unmappable. - though the PI version is determinate and always plays the same, I believe. Because pi is always pi, but even if you use some randoms unless you seed randoms the patch always plays the same from load (zero time), because they're pseudo random sequences. That's a neat thing for composing. The fibonacci sequence structure was there though, and possibly the only overt display of math, as that sequence controlled when different parts began to fade in or out, within a set plan I'd laid out on paper. I listened again and I hear it clearly where it alters the timing, that definitely works very well. Unfortunately, although the sound at the start is synthetic, it is from a VST, and not synthesized in Pure Data. I'm not convinced I could even run a big, polyphonic subtractive synth built in PD currently, I fear with so much running it would most likely eat my entire CPU on WinXP, so using VST's in PD has been my compromise. Actually, because of that and time constraints, it was either use VST's, or ditch Pure Data altogether for the project. The piece as a whole did push my CPU pretty much to the limit, especially with the reverb added. That's interesting, how you use Pd and how efficiency and the sounds you use influence how it turned out. The quacking = simple fm chirps, that wasn't how I originally intended to realized that part of the composition, but the deadline for the piece was today (on the microsound list). I do intend to make a new version next week though, and if I'm lucky I can synthesize something closer to my original intention in PD. Also, as I've said before, low-level DSP isn't really my thing, I'm more into the composition side of things and at least some higher level modular components. Anyway, this piece realizes only about 1/3 of my original plan, though now that the important abstractions are built I could realize new versions more quickly. Yeah, it speeds up quickly when you have a base of abstractions and tools and things ready built. Same with any environment I guess. I'll have a look at those abstractions, thanks! I must mention that none of this stuff would be possible without ZEXY, Frank's list-abs collection (and especially, I must mention the [line-interp] which I only just discovered after working on a different solution to the same problem, and Grill's [vst~]. So a big thanks to all those who contributed in those projects! Sounds like you had a lot of fun, I think the results turned out pretty good. best, Andy ~David On 3/24/07, padawan12 [EMAIL PROTECTED] wrote: Thanks for sharing that I enjoyed it.

If you like textures based on dilating/warping events the attached patches might inspire some ideas. The first is for an elastic object that gives up a little kinetic energy on each bounce, the other is a fragmentation model for something falling apart that uses bifurcation. They're for bouncing balls and breaking glass for me, but I think they have compositional uses if you twist em a bit.

I suppose it depends on your goals, for example a lot of composers learn a disproportionate amount of stats and distributions. I'm humbled by those guys. I borrowed an extra book from my probability teacher (since probability class at an art school is kind of tame), hoping to understand Gaussian, Poisson, etc., after seeing them in the Csound manual, but I'm kind of marooned. Can you remember what it was? I say disproportionate, but really from ignorance of use in composition. For sounds generally they are useful. The times I've encountered that theory was with water, where I found bilinear exponential to be useful, gaussian normal and 1/f for damping effects. I think there was bit of talk on this list about perlin noise and somebody mentioned 3D terrain generation, I'm generally interested in that and other natural distributions that can be used for textutred extents. I think if I understood more behind the statistical theories I could link them better to observed physical behaviours. But there's a lot to think about, http://en.wikipedia.org/wiki/Probability_distribution Having the graphs printed on the right is really useful because in stats talk some familiar curves are called by different names. Probably half of them are no use for sound applications at all. Poisson should be useful for rain and breaking glass and quite sparse events I guess. Also I thought all the tons of stats work that's been done on earthquakes is probably useful to model any type of frictional excitation generally, I mean if it works for tectonic plates aren't the same principles there between a violin bow and a string? You never apprehend the object as a whole, because you don't know what comes next. Then again, I just apprehended that bottle of lager as a whole, so I'm not sure if I'm making much sense...

Another take is the hoover-pwm.pd, which is a juno voice basically, it's much brighter and fizzy down low. It just depends what you want more in the low registers, up high theres not so much difference. One is pulse width mod of a square, the other is slope mod of a triangle, both have a bit of frequency lfo on too at about 5 Hz. A fat Juno hoover noise uses the fast chorus so there's one on both versions. Each has the same sequence so you can compare the sounds. All the hoover flavours have a different character, like a highpass resonant filter makes an interesting addition. But what they share in common is a busy sound made by having 3 or 4 detuned components. Juno is a pwm + saw + square mix, with the square an octave down.

This is the weaponised version with no anti-aliasing whatsoever (apparently that makes it sound better). Careful, it's already claimed one set of speakers. You might want to put some filters on the output to tame it a bit. But it's not classic hoover. You want lots of detuned triangles for that. Somewhere there's one called Edgar.pd I made which does that quite nicely, but just rip the dual slope triangle out of this one, dupe it a few times and give them a spread of about 3%, that's the secret ingredient.

Re: [PD] Superdiscounter
But I don't think you can update the jitteryness (can I say that) of metroplus on the fly like with this. For humanising drums this is the way to go because it seems happy with you updating the list without any hiccups. There's some rules for humanising based on anatomy/physical ergonomics, a drummer will tend to lay back one side, so depending on how the kit is set up and the drummers handedness (left/right) you'll get some crosstalk between the snare and kickdrumtimings. Cognitive/psychoacoustic factors mean there's two scopes of timing, that enables a drummer to keep track of a larger scale timing while bringing individual hits back and forwards. I think you could use the [superdiscounter] to make some pretty neat grooves by slowly changing the list.

I don't know if it's because Pd is younger, or less popular, or just that it hasn't accepted many externs into the mainline (as Csound has ravenously), but unlike Max/MSP or even Csound, Pd has very few effects you can realize without knowing *exactly* how the DSP behind them works. With Csound you get medical student brain, loads of built in functions parameter lists memorised by rote. Pd is nice because you understand what's going on because it's right in front of you, or because you built it or can open it and see how someone else built it (abstractions). And you can also get stuck right in and bend it and change it, great learning value, a big benefit of open source. That and the help files. Pd has so many great well thought out help files. When I was a total noob realising you could just right click and get help was the fist major money shot.

The Kawai K2000, K5 and K5000 are all additive synthesisers.

It is the tweaking of those input parameters that creates the filter-like effect.

If I remember correctly K1 was 4 part per voice, just 4 static spectra with an envelope for each and you could modulate two of them together which made some neat ringmod type effects. It was advertised as an easier to program version of the K5, but in fact it was nothing like it. The K5 had some really fancy breakpoint envelopes that were very flexible, with a kind of matrix to assign each env to one or more groups of sinewaves. It needed plenty of time and patience to program but made some sounds that were unrivalled at the time. I also get those mixed up. The K2000 was a Kurtzweil now I recall, a development of the K1000 additive synthesiser. That one really had individual sines and was quite a beast. The resonant filter is actually an FIR Comb filter with very tight bands. In addition, it is pre-programmed with an envelope shape for a really dynamic sweeping effect. Ah yes, that would be lush to follow up an additive stage with. Placing the bands at some ratio (a/b * f) of the harmonics would make them all pop in and out in some sequence when you sweep it. Follow that up with a bit of delay and you have a very sparkly sound. so something with bandpass filters would be great, which are used for formant filters and vocoders. Have you checked out the Lattice filter object? Of course these approaches are not as precise as resynthesis but have a destinct sound without the additive sparkle. I am about to create a morphing filter synthesizer with some bandpasses in pd with the Emu Morpheus in mind. Although they interpolate the filter coefficients to create the dynamic morph. Sounds great, look forward to hearing that one. Can the biquad or FIR objects do this? How dynamic are they, I nether tried them... No. Well not by interpolating the coefficients directly. It will go unstable and blow up at lots of places. You need to do the interpolation of the parameters before the intermediate stage variables.

[PD] Re: Looping
Looks like you cut it right for the phase actually. What I notice looking at it in the editor is quite a bit of VLF, there's a wobble in there at about 2-4 Hz. Very low frequencies tend to give you a DC offset mismatch wherever you cut it, so try high passing it at above 20Hz. Also, there's a bit of movement in the spectrum up top, quite a noisy effect that might be making it difficult to loop without an apparently sudden change of timbre. There are two ways around this. One is to make a crossfade of 3 sections, mix them down and then cut it 1/3 of the way from each end, the start and end will have the same spectrum. The other way is to double the length of it by copying, reverse, invert phase and insert append (you get a symmetrical forwards - backwards loop that starts and ends on the same spectrum) On Tue, 30 Jan 2007 11:18:37 -0800 (PST) PORRES [EMAIL PROTECTED] wrote: thanks, the samples seem to be ok when looped in sound forge and all... check the wave loop file attached. cheers alex Charles Henry [EMAIL PROTECTED] wrote: Hey, there, Alex, I had been talking about this with Andy a while back, and we concluded that clicking occurs because of phase discontinuities between the beginning and end of the loop.

Are you saying it's only possible to manipulate time in powers or two, like ... 1/8, 1/4, 1/2, 1, 2, 4, 8 ...? Or is that a limitation of the implementation (your stretch function). Also, what are the possibilites for interpolating between wavelet coefficients taken from different sounds as a kind of cross-synthesis?

Re: [PD] Granular Cross-fader
Sounds good Kyle. If you listen to old skool house DJs they often use the tone control to start with only the hi-hats/top of the mix (because that is where you get the best time acuity) then as the mix fades to the second part they drop in the bass. For the mostpart only a few parameters will work for the grainsize and randomness without it sounding watery and blurred, an optimal window size and overlap. The starting assumption is that you have two audio files and two phasors/line segments that give you a pair of timelines that are locked in beat sync. The most obvious granular mix effect is to mix N grains from one side with 1-N grains from the other per unit time. But the weight/density of the sound is a product of the number of grains per unit time and the grain size, so another mix would be to increase the size of one grain stream and reduce the other. You could make another interesting effect by dissolving one stream into chaos by adding random time offsets to blur it out, and then quickly mixing the other one in with the same amount of blurring, then bring the new stream back into focus. As far as tone/spectrum goes, smaller grains will generally be higher (because they must contain shorter periods) and longer grains will have more low frequencies. Either way, you'll get modulation artifacts for grains whos period is less than 1/F if F is the lowest frequency in the mix, but I assume that is okay, just part of the effect.

I'm in the pre-planning phase right now, and would love to get some ideas/suggestions for how to implement this. Basically what I'd like to have is similar to a DJ cross fader, but using granular methods to stochastically mix two (or more) signals using various common granular ideas (pitch shifting, time stretching, grain size, randomness parameters, overlap, etc.). This would make transitions much more exciting from a DJ end as well as when mixing two or more signals on a DAW.

Re: pd sl (was RE: [PD] Shoutcast~ for OS X?)
I did a quick scan of some SL info and yes, it seems you just need to start a shoutcast on your own server (you'll need it on a box with a fat pipe not your home machine probably) and the URL is passed into SL from where the clients pick it up. No need to make a replicatable object afaics. Check out the CVS that Georg gave you and compile that to experiment, but ultimately you'll want one that fits your server architecture. You will want to run pd -nogui on the remote. I'm sure we can all help you with this. But alas, like shift8 says, us Linux users can't join in the fun with the dancing cocks just yet :) I'm sure you'll find a few Pd musicians who would be up for doing a virtual gig at your island club too.

Sorry, no coffee yet. I didn't see the noob bit, welcome to the puredat list - that diagram is probably very confusing.

If the synth is washed in reverb too much I think you lose the focus of the sound, the sound becomes all about the reverb and not about the synth, so you lose control because you cant really hear it anymore as you twiddle the controls. I agree about dropping the freeverb from the patch, as it's really better to let people choose their own (or no) effects unless it's truly integral to the synth's sound. And it makes things more portable and usable on lower spec hardware too. However, I disagree about reverb being a global effect unless you are Phil Collins. I think this depends on the genre. Yeah totally. I was being a cock about Phil Collins, it's just that late 80's hey we can afford 10 of those Yamaha REV1 boxes so lets use them on everything that grates on me. Some tracks use reverb totally disparately to create a good effect, and honestly, there's no reason *not* to have a synth patch or entire track based largely on reverb effects - I just think it's a common mistake when building and composing with synths to begin with adding too many effects on each one, and ending up with over-dense mixes. How much reverb and what kind? That's an old favorite ;) ! I'm of the less is the new more school this week :) Specific purposes are worth remembering, like you say, the difference in where you want the best replay sound , headphones vs a club PA is a proper baffler, and as usual there's a happy compromise to seek that defines your own style. I make quite a bit of techno/house/electro/minimal, and to me reverb is almost never a global effect. I usually use it (or a synced delay) on one or two sounds in a mix which need to have a sort of floating/wash feel and lay over the top. I see, you target specific elements you want to have a reverb. I guess I do too, I mean being selective on the global reverb(s) mixes, though the aim is often to bind things together that want to be in the same space. I say reverb(s) because actually I think the best result is obtained by using two processes, one to handle the early reflections, the hardness and tightness of the reverb and one to handle the wash, but they have to work together. But the key to getting nice and tight percussion, and very clean mixes that will sound right in a a big room, is having most of your stuff totally dry with no effects at all, except compression of some sort ... Yeah agree, that early detroit and NY techno was so powerful because of it, the clubs gave the sound it's life and you could pump it up big because it was dry. I might have 8 fx tracks, and just one will have reverb, and a second delay. This assumes one is making tracks that may be played on a club system at some point. Headphone/listening music would give one more leeway. But this technique been working for me as my stuff is sounding quite good on those systems -- comparable to other stuff I've been playing out with my own stuff side by side. Note, I'm not saying put different reverb on each thing - but rather use a single reverb, but only on one or two elements in a mix. This being the case, you still wouldn't want the reverb built into the synth, as it needs to be applied in terms of the mix as a whole. Just my personal opinion. Good one. And I suppose it depends on your mixdown style and way of working too. I have grown fond of jack-rack and leaving all those processing decisions right till the last moment. Having said that there's probably room for a few more good reverb objects in Pd, things like [vdn~] and whatnot, maybe some nice convolution.

Re: [PD] fmbox patch for d/l, improv
That's wicked fun. It's got loads of sweet spots, I've just been messing with for it for half an hour and had some hilarious and some beautiful sounds from it. You've got a 4 op FM algorithm with fully connected feedback so the range is huge, and I love the extra filtermaina where you're using the operators to modulate the filter too :) That's crazy but, it sounds brilliant on slow waves! Personally I'd drop the freeverb. Lot's of people seem to put a reverb on their synths then get to see it's really best without it. Reverb is nearly always global effect in most cases, unless you're Phil Collins and want your drumkit to sound like each drum is in a different room. If the synth is washed in reverb too much I think you lose the focus of the sound, the sound becomes all about the reverb and not about the synth, so you lose control because you cant really hear it anymore as you twiddle the controls. I think you'll find a few peeps have made cool ambience and texture synths, check out Alberto Zins outerspace and some Claudius-Maximus patches like Chaos engine. You might also like the machine machine in my collection. Nice GUI too. Improvements you could make are to add offsets between the frequencies ;) !!! And a little bank of presets where you've programmed a few juicy patches is always really good when you lok at new synth, it gives you a quick overview of the kind of sounds it can make, so you can quickly choose if it's right for a part. The difference between using a named send~ and a connection is negligable or null, but there's a disadvantage (and feature!) to using [send~] and [receive~] which is a 1 sample delay. There's also a lovely feature (hideous bug) that means the order you create sends and receives makes a difference, but otherwise don't worry about the efficiency.

Presumably they play OK for everyone, that's just the upshot of writing only in Miller Vanilla and avoiding any externs not in the most basic distros. Comparing this to my old way of working on TV music, I would have to keep track of so many file formats, midi, VST plugins, or worst of all on Protools when everything was stored in one monster proprietry blob along with redundant data. It tied me and my colleagues to a particular studio setup, or required hours exporting and importing between applications. Everything revolved around mixes, samples, crystalised and clinically trimmed to the beat loops. Yuck! This way everything stays as fluid *data* right until the last moment, so it can even be parameterised in situ, which is exactly what is needed for games or interactive application music.

Re: [PD] bang when phasor~ reaches 1
The solution Marius offered is probably the most reliable. I've used Jamies [snapshot~] based solution in many cases it works fine, but sometimes misses a beat. It's because the blocksize (nominally 64) on which [snapshot~] operates may not contain the zero you're looking for. The thing you want is [delta~], but you can make your own arrangement with a [z~] and a [-~]. Basically look for any large dx/dt, not just negative, remember that a phasor can also be negative in slope, ie [phasor~ -100]. See also that as the frequency increases toward a high value eventually the solution will fail (each rising slope will be sufficiently fast to trigger the delta comparator. Theres probably a more elgant solution, I heard Martin Brinkman is a good chap to ask as he tends to work in the signal domain and derive his control messages.

Re: [PD] Pure coherent noise (Perlin noise)
On Wed, 15 Nov 2006 13:00:55 +0100 [EMAIL PROTECTED] wrote: Martin, We can imagine applications of multidimensional noise. Yes, the concept is clear enough, for example static on a black and white television screen is 3D noise (x, y, brightness) and for a colour picture we can add two or three more depending on the encoding. But you need to be rigorous in defining a few things... I was thinking about a melodic line piloted by a one dimensional Perlin noise. No problem. In d1 you have only a number line on which new values appear with a magnitude given by a probability inherent in the noise spectrum. In this case there is no difference between noise and a walk. If the random signal is bipolar then adding a new value to the previous one (a one dimentional vector with a sign if you like) then the result is not distinguishable from simply using the random signal values. The view of the noise as a spectrum, and the view of the noise as a walk, which on balance will have an average of 0 and always return to the origin, coincide. With an infinite number of vectors you will cross the origin an infinite number of times regardless of your scale. In d2 we have to look at things in a clearer way. Now it really makes more sense to look at it as a walk on a 2D surface (and it helps to switch between cartesian pairs and polar pairs so that we can control direction and magnitude independently too) Why? Well consider the jumps that would occur if you just used an x and y value as two independent random values. On one step it could occupy an extreme corner, say 255,255 and on the next step it might go to 0,0. For a melodic contour with sensible deviations you need to take the last x,y coords and add a scaled (small) x, y offset to it on each step. I think this is what you mean by track when you say... But the second will still able to track the first one, to come closer, to go away and then back close to the initial pattern. You can see experimentally and from proofs that it will still return to the origin for any number of iterations. Practically it makes sense to wrap your d2 plane (into a sphere/torus or reflected onto aliases of itself) because real life random numbers you might want to use to perform music and the theoretical ones we are discussing are different worlds. In a gig you probably want the numbers constrained in spacetime in a reasonable way so that the audience don't have to wait millions of years for it to come back to a useful range. Also because the noise (chaos in fact) generated by libnoise is deterministic, one can also experiment with two patterns in advance (or delayed) respectively from one to another. Your chances of perceiving those relationships are small. Even though it's pseudo-noise you would be best to treat it as real noise for all practical purposes. Which leads us to the concept of noise in d3. Given an infinite number of random vectors in d1 and d2 the probability of returning to the origin is 1. In other words the walk occupies a bounded spacetime, even if it is unbounded in either space or time separately. But in d3 the probability of it returning to O is not one, not even with infinite time, it's about 0.3 afair according to Polya. This is profound and has many implications, not least of all for space travel. I haven't really considered what that implies for music, but you still have to coax or coerce your random 3D walks into a space you are happy with, which is non trivial in 3D. In other words, I would use it as a control rather than as a signal Yep, as a control signal rather than an audio/visual signal. Which means choosing a mapping of your parameter space onto the control space, for example in a trumpet melody, d1=pitch, d2=embrochure d3=dynamic, d4=mute d1 is constrained to a small range but free to move in fairly unconstrained jumps d2 and d3 are codependent, there are values of pairs d2,d3 that don't exist in reality (or for your synthesis model) so they have to be linked in a sensible way. d4 is probably a boolean or only occupies a few values, the mute is either on, partially on, or off (disclaimer: I'm not a trumpet player so I'm guessing this). So as you see, the control space you may have and the parameter space you wish to navigate may not be congruous (I think that's the right word)... they don't fit over each other nicely because some dimentions are stretched. If you can normalise your spaces you can do musically interesting things, like rotating a gesture in the pitch-dynamic plane etc../ Hope this makes some sense, it really is a subject that benefits from pictures and diagrams more than most. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: 14 November 2006 18:17 To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; pd-list@iem.at Subject: Re: RE: [PD] Pure coherent noise (Perlin noise) You can make coherent noise by adding filtered noise~ objects.

Re: [PD] running PD from a USB stick / drive
Going from scratch for a single purpose USB boot I would go the DSL route because it's so easy, thre's a make USB install script that adds a filesystem, isolinux and installs the rootfs and all that stuff for you. Another script allows you to work on the custom image using apt so it's straightforward to remove lots of stuff to strip it down without falling into dependency hell, then just add the Pd/GEM deb packages. You could probably keep it down below 64M with a bit of care.

Re: [PD] CPU cost II
You couldn't reasonably tag every object with a cost because that might change for many reasons, but you can know the load of an object or patch on your current CPU using the [cputime] object which shows a percentage scale. You can usually use it to work out the heavy offenders by muting DSP with [switch~] and seeing what is using up lots of cycles, but it's not really accurate benchmarking.

Re: [PD] control signal sample speed
Yes, convert your control signals to audio rate with [sig~] (maybe interpolate them too using [line~]) and then use [vcf~] which has an audio rate Cf I'm not sure about a-rate control od Q though.

The difficult part is that this cilinder I am modeling is constantly changing its volume, thereby changing its resonant frequency and Q. This works well at lower speeds but the trouble is that the cycles go up to once every 30 milliseconds. This means that the frequency and Q go up and down again 33 times per second. Long before these frequencies this setup tends to explode and create feedback. My thoughts about my problem tend to point at the Nyquist frequency of control signal sample time. Is this true and can I change the sampling speed of control signals? Of course I thought about sending the data in audio signal but [bp~] does not accept that of course. Is there another filter out there that I can control with audio signals if I cannot change the control signal sample speed? _ All-in-one security and maintenance for your PC.
