Re: [PD] No loadbang in dynamically created objects
Great, I just realized this was recently touched up, so sorry for the repeat thread. This makes complete sense, the polyphonic host to my dynamic object creation is now sending [loadbang( messages to the newly created patches.

Am I missing something, or did I just stumble upon a bug? [loadbang] is something that has to be banging whenever the patching is finished. The patch that does dynamic creation is the one that is responsible for loadbanging the objects. Basic Pd only allows loadbanging a complete canvas, by sending a loadbang message to the canvas. However, there are extensions for doing other things. For example, [gf/canvas_loadbang], together with [gf/canvas_count], allows you to send a loadbang to only the newest objects, in a canvas that had already been loadbanged. (The rule is that loadbang should be done only once per object at most, never more than that.) Note that creating objects manually also does not cause any loadbangs, though it would be a good thing to have a menu item for triggering loadbang on objects that didn't exist back when loadbang was done in that canvas. That would be a quite awesome shortcut. __**__** ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC -- Brandon Zeeb ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] timing
If Pd's default block size is 64 samples, and events are only processed at the beginning of a block cycle. Therefore, if you're running at 48,000hz sample rate, then your Event Rate is 750hz. Likewise a 96,000hz sample rate will give you a 1500hz Event Rate. As Mathieu mentioned, if you need anything higher than this, your only options are: 1. Decrease your block size 2. Calculate at audio-rate using ~ objects As for between samples, are you referring to some kind of upsampling? In that case, either increase the sample rate of a sub-patch using [block~] relative to the current sample rate, or use either a [delread~]/[delwrite~] pair or [fexpr~] to hold the last sample value from a given stream for calculation. ~Brandon ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Events a.k.a messages are 'virtually' [1] processed at any time (literally any time, which includes any time between samples. The only restriction is the resolution of the 32bit floating point number format used by Pd). This can be easily shown with this little patch: [metro 3.1415] | [t b b] || [timer] | [3.1415\ - number box You can change the metro to any value and [timer] will report back exactly that value. AFAIK, this exact timing occurs as long we're considering the message-only domain. However, there are some objectclasses which accept messages at the inlets and produce signals at the outlets, e.g. [sig~]. Many (almost all?) of them only evaluate the messages _at_ block boundaries and thus the resulting signal can only be changed at block boundaries. This effect makes the messages look like they only happen at block boundaries, although they actually happen at any time. There are other objects that work in both, message and signal domain, which don't suffer from that problem: [vline~] and [vsnapshot~]. Both take the exact timing of the message into account. [1]: I say 'virtually', because Pd actually really computes one or several events only once per block, though is this done transparently when looking from the outside. Summary: * [metro] and [del] are as accurate as you can wish them to be. * Always use [vline~] when timing-exact conversion from message to signal matters * most tilde-classes with message inlets ignore the timing of the messages * You don't need lower block sizes for having exact timing in the message domain * Messages triggered from external sources (GUIs [bng]/[hslider] etc., MIDI [midiin]/[ctlin] etc., networking [netreceive] etc., serial [comport], etc.) usually don't have more exact timing than the block size.

Re: [PD] PD OOP?
In my experience with emulating OOP in Pd I've had moderate success. As a Java developer by day, I find myself attempting to recreate familiar patterns within Pd (ie: usually IoC and Flyweight in Pd). Main problems with recreating OOP in Pd are the following: 1. Everything is global 2. No control over abstraction (object) construction order and lifecycle 3. No introspection (although not required, very helpful, and don't tell me it's in some external, I don't care!) 4. No concept of this 5. No interfaces or abstract abstractions (to control inlet patterns) 6. Unfriendly and inconsistent type system (it is cumbersome in real use, although I get over this by using [list]) 7. and on and on In most Pd patches, I see people using a few lookup tables again and again (ie: mtof). As this is a complete waste of memory, one can attempt the Flyweight pattern. However, doing so in Pd is a very dangerous game, as you will have NO idea which abstraction first created the table and thus have no control over retaining access to it. In my library I've dropped this approach in favor of something closer to IoC. Basic IoC is very possible, and indeed very rewarding. Very often I pass in other abstractions as object creation arguments. The most simple example of this in my library is my [bypass~] abstraction used to dynamically enable and disable a given abstraction. I use this EVERYWHERE to save CPU cycles in combination with another object to programmatically disable the sub-abstraction when the user selects a given value (ie: when the filter cutoff is at MAX with no resonance, disable the filter). In use: [bypass~ some_process~ 330 1 3 9] Where [bypass~] expects it's 1st argument to be an abstraction and the next 10 to be arguments to that abstraction.

Does that sound good ?
That's not a bad idea! Essentially attempting to delegate the creation of
the table.
In a given abstraction you do NOT have control of the order in which your
abstractions are created in memory.
Yes you do. It's the implicit object numbering. You can renumber an object
by deleting and undeleting it. Any new object is created at the end of the
order, such that when you save the patch, it will be reloadable in that
order.
That said, it's considered bad practice to rely on this. People who need to
rely on this may use dynamic patching instead.
Perhaps, but not if you're creating the objects by hand. As you say, it is
a bad practice.
I care more about Pd as a language and as a means to learn. For my
purposes, using externals is pointless,
I beg your pardon ???
Pd with a lot of externals is a language too !
although I do appreciate all the hard work.
do you, really ?
Why are people getting offended here? I'm simply attempting to avoid
information overload, my background is primarily in software development,
not DSP. I use Pd to help learn these basics, and I will use pd-extended
when I've mastered the basics. With that in mind, what's the point in using
a pre-baked filter if I haven't created my own and don't yet fully
understand the theory behind it? This says more about me than it does you
:)
Basically, an abstraction (or object) is given what it needs to function by
a 3rd party.
Ok, then connections are given to the abstractions in a kind of attribute
that we call an outlet : wouldn't that be a form of IoC ?
Nope, that would be delegation. A simple example would be this. Assume you
have an abstraction which uses [metro] to synchronize a particular process.
Now, if you wanted to synchronize with mates on the net using [netro],* you
would have to create a second abstraction*! Using IoC / Strategy, you
create your abstraction and pass a symbol referencing the metronome you want
to use. In Java / Spring IoC psuedocode:
class DoFunThings {
private ICounter counter;
private ISomeFunThing funThing;
public void setCounter(ICounter newCounter) {
* counter = newCounter;*
}
public void setSomeFunThing(ISomeFunThing thing) {
funThing = thing;
}
public void doIt(Intlet inlet1, Inlet inlet2) {
* int val = counter.next();*
funThing(val);
}
}
/// now let's build it
ICounter netCounter = new NetCounter(127.0.0.1);
DoFunThings myAbstraction = new DoFunThings();
myAbstraction.setCounter(netCounter);
//... this is boring
myAbstraction.setCounter(new LocalMetronome(100));
Within Pd we can't achieve pure IoC since we can't construct abstractions by
themselves and pass them into other abstractions. Although, we can only
pass along the name of the abstraction with it's creation arguments. This
rides a blurry line between Strategy and IoC patterns. Is this making more
sense?

Given the distance d1 and d2, these distances are usually identical in a traditional bitcrush or simple quantization. I would like to be able to vary the distance between points of an incoming signal such that the distance between points is a function of a given quantization value, the current Y value, AND a given quantization curve. As a first step (and illustrated in the attached PNG), smaller values of Y will produce a more pronounced quantization given a x^2 quantization curve while larger values of Y will produce a smaller distance between steps.

I'm looking to quantize an incoming signal (or value) given a max and min quantization value and an arbitrary curve. Think quantization of note events to a series of note lengths or your standard bitcrush algorithm, it's pretty much the same. The arbitrary curve should influence the degree to which the bitcrush algorithm is applied to the signal such that one could have less quantization at smaller values of the input signal, and greater quantization and larger values (or vice versa). Simple table-lookup is insufficient as it requires you to pre-define a maximum input signal amount. I'm willing to waive this requirement if an implementation is not possible without it. This will be used in the following circumstances: To quantize envelopes signals to any arbitrary series (say !, Fibonacci, x^2, 2^x, etc) To quantize signal loop length values to an arbitrary series of note values (say 1/16, 1/8, 1/2, 1/1) To apply non-linear bitcrushing to a signal such that higher values are expressed with less of an effect than smaller values To quantize pitch events to a pre-defined series Is this making sense? My attempts thus far has extended the RjDj bitcrush abstraction with mild success.

Comparison with AudioMulch, which also uses Portaudio suggests that is only in part a Portaudio problem. AudioMulch idles at ~10% on my machine. I suspect that the problem with Pd+portaudio may be due to a small buffer size used by Pd. I thought Pd's 'Delay' setting in audio preferences was supposed to handle this, but changing delay to 500ms, has no effect on CPU use. Also added to tracker.

[PD] Non-Linear Quantization / Bitcrush
Hey All, I've been burning my brain over this issue lately and I can't seem to come up with an elegant solution, and stay with me here as I attempt to explain it best I can. For me and my needs, being able to quantize an arbitrary signal to any arbitrary series is the Holy Grail (and I'm not talking about simple table lookup!). I'm looking to quantize an incoming signal (or value) given a max and min quantization value and an arbitrary curve. Think quantization of note events to a series of note lengths or your standard bitcrush algorithm, it's pretty much the same. The arbitrary curve should influence the degree to which the bitcrush algorithm is applied to the signal such that one could have less quantization at smaller values of the input signal, and greater quantization and larger values (or vice versa). Simple table-lookup is insufficient as it requires you to pre-define a maximum input signal amount. I'm willing to waive this requirement if an implementation is not possible without it. This will be used in the following circumstances: 1. To quantize envelopes signals to any arbitrary series (say !, Fibonacci, x^2, 2^x, etc) 2. To quantize signal loop length values to an arbitrary series of note values (say 1/16, 1/8, 1/2, 1/1) 3. To apply non-linear bitcrushing to a signal such that higher values are expressed with less of an effect than smaller values 4. To quantize pitch events to a pre-defined series Is this making sense? My attempts thus far has extended the RjDj bitcrush abstraction with mild success. I can recreate the effect but the output signal bears too many artifacts from the input signal (ie: the curve retains part of it's original slope from the input signal and is not flattened or held until the next value).

Re: [PD] dub chords in Pd
To Roman's suggestion, this works well. For the sake of your speakers and DSP chain, I'd add a [clip~ -1 1] to the end of that to be safe, and place that combo both right before the [delwrite~ dub] and on the output stream. For the sake of maximum dub, use a [vd~] instead of a [delread~] and slowly apply modulation to the base index delay amount. Say, 500ms +/- 50 by modulating the base amount either with a periodic function or [lop~] filtered [noise~]. I've yet to try this, but in my head it seems dubby.

Re: [PD] dub chords in Pd
Agreed, Check the help patch H15.phaser.pd and H03.band-pass.pd, I'd start with running your favorite saw chords into a bandpass filter triggered by note-on, sweep that downward. Patch that into the recirculating delay Andy described (touch of distortion with a bandpass in the delay feedback loop). Finally, add a phasor to the final output. For maximum dub, dangerously vary all important parameters. In sum you have three components: 1. Simple instrument with bandpass filter descending (and resetting) on note-on 2. Recirculating delay with slight distortion on the input, and a bandpass filter in the feedback loop 3. Phasor on output You could probably do similar any number of different ways, but this is how I'd try it.

Each time around the loop the distortion function shifts some of the energy away from it's original position, some up and out band and some into the capture of the bandpass. As it goes round and round (recurses) it gets focussed more and more into one or two places. Good dub delays are always pretty close to exploding in certain frequencies close to the 1-2kHz mid. That's the trick. You need to experiment with dangerously unstable settings to get it to sing. Distortion followed by bandbass.

[PD] Introduction to elementary filter components in Pd
Greetings, So I'm reading Miller's book hoping for a real world explanation of the elementary filter objects in Pd (z~, rpole~, czero~, etc). Unfortunately, this only occupies 3-4 pages. Does anyone have a set of tutorials, abstractions, or are their any documents available which go into further detail into these objects? For starters, I'd like to build a few simple classic filter types (ie: lpf, hpf w/ recirculation). lop~, hip~, and bp~ are nice, and one can build recirculating filters with these, but they don't offer audio-rate control of filter cutoff. So, for an intermediate to advanced Pd user who would like know more about this real, what would you recommend?

[PD] bang~ event resolution
Hello, With regards to the block limit thread and the following previous discussion [1], I have a question regarding event timing resolution in Puredata. In the previous email thread, it was noted: What is also interesting, is that i get the double value of 2.9 msec for blocksizes above 64, for example 65 and above. There are no adc~ or dac~ objects or any subpatches in this setup. Does this mean that the resolution of a bang is in *multiples* of 1.45msec? For example: 1. If I am attempting to send a message every 8msec (5.51 dsp blocks), will the event actually be sent, rendered, and perceived to occur every 8msec or will it be rounded up to the next block ( #6 ) at 8.7msec? 2. If an event is scheduled to occur every 1.50msec, will it be scheduled in time every 1.50msec or every 2.90msec? I've read the pertinent section of Miller's Theory and Technique of Electronic Music, but I guess this is one small bit I'm still hung up on.

Re: [PD] parallel processing
More specifically, my question is: How does PD's performance scale when the number of available processing units increases from 2 to 4 and to 8 cores? Is the main engine written in such a way as to take advantage of this, or is it primarily a single-threaded? Possible scenarios could be: 1. I have a patch with 8 very intense sub patches. Do all of these sub-patches run on the same core or are they spread out across available processors? 2. Assume I have an 8 CPU system (dual quad opterons etc). I have 8 patches open within one Pd instance, do all 8 patches run on the same core or 2, or do they spread out across all the available 8 cores? Besides running multiple copies of Pd, how does Pd scale on many-cpu systems?

First use rsync to get the code: http://puredata.info/docs/developer/GettingPdSource Then install all the dependencies: http://puredata.info/docs/developer/darwin Then add the script to a cron job so it runs automatically: pure-data/scripts/auto-build/pd-extended-auto-builder.sh Universal builds for Pd-extended won't work, but it wouldn't be too hard to get working, and very much a worthwhile project. .hc On Jan 25, 2008, at 2:11 PM, bsoisoi wrote: I have a 1.5ghz powerbook G4 with 2gb of RAM that is acting as a server for me right now. It is running 10.5.1, and I'm pretty sure powerpc macs can build Universal Binary / Intel binaries. If someone can figure that out (or help me figure it out) I can donate dedicated CPU time on this machine for nightly Pd-extended PPC/Intel autobuilds.

If someone wants to tackle that, then we can just have universal builds every night on whatever machine AFAIK. .hc On Jan 20, 2008, at 11:28 PM, vade wrote: What machine is it hans/marius? Perhaps we can set aside an intel box for um, us researchers and we can leave it on :) Since I am probably around more than Hans is I can check on it periodically. I believe PPC systems can compile intel builds, with 10.5, no (im not positive but I think you can target them??)? If so, we may have a spare machine for this at Poly we can put in the research area that no one will mess with...

Afaik the machines got totally reset for the beginning of the new semester (starting with jan22). don't know if it will be up again. hans? marius. bsoisoi wrote: Hello everyone, Is there a reason there hasn't been an autobuild for Mac OS X x86 since around 2007-12-07? Do we know when we can expect the Intel builds to resume?

Re: [PD] Pd-0.40.3-extended and Pd-0.39.3-extended on 10.5 Leopard
I second that. It runs fine on OS X 10.5.1. Good work, Hans. Thanks for the quick response. btw, to all Pd devs, you all are doing a great job. ~Brandon On Nov 17, 2007, at 12:26 PM, marius schebella wrote: good job! first of all: no crash with the help menu and no crash on saving... thanks a lot. marius.

I don't want to say this loud, but I had to switch to max to do some work that needs to get done immediately. (the problem is more related to Gem) at least I will be able to write good documentation about the differences betw. gem/jitter pd/ max and maybe think about translators for the future. Is miller's pd using another tcl/tk version than pd-extended? marius. Hans-Christoph Steiner wrote: I am in the process of upgrading the Tcl/Tk version for the nightly builds. I should have it done today, so tomorrow's build should include it. The new version of Tcl/Tk is supposed to address some of these crashes (I think they are related to Apple changing somethings in the push to make everything 64-bit, but I could be wrong). Please let me know whether this works for all y'all early adopters :) .hc On Nov 16, 2007, at 9:03 AM, Si Mills wrote: Hi Apple released 10.5.1 update today and it was hoped that it might solve this issue, but it doesn't seem to be any different. hopefully this will be rectified soon! thanks On 16 Nov 2007, at 13:07, bsoisoi wrote: Hey all, is anyone else having difficulties running either version of Pd- extended on OS X 10.5 Leopard?
