[PD] No loadbang in dynamically created objects
Hey dudes, I'm on 0.43-0 vanilla and just noticed that [loadbang] bangs are not being fired within abstractions which are created dynamically.

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] 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

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

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?

Re: [PD] PD OOP?
Agreed. By "everything" I should have been more precise: 1. tables 2. ui elements 3. values 4. send/receive 5. throw/catch 6. I'm probably forgetting something... All of the above are available globally within a given patch without some kind of namespacing (either with $0 or some eventual derivative thereof). In a scalable Pd patch, this makes up most of the communication in a given patch. You are right, when something must be local, a patch cord is most appropriate.

Re: [PD] PD OOP?
#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 Say you compute a raised cosine window and store it in a table, this table is used within one instance of a granular table reading voice abstraction, 1-n of these abstractions are created at run time for polyphony. Now you have N instances of this table. Some people cache mtof in a table, and thus that was my original point. 2. No control over abstraction (object) construction order and lifecycle In a given abstraction you do NOT have control of the order in which your abstractions are created in memory. With my attempt at the Flyweight pattern for large lookup tables, it became apparent that if I were to remove an abstraction while editing a patch, I would have no idea if I removed the abstraction with reference to the real table or not. This is almost similar to prototypal inheritance where the instantiated object controls the resource, not the prototype. For example, a given UI on an Android phone widget will usually share graphic resources with others of it's type to save memory. IMHO, directing your criticism at pd-vanilla alone is extremely unproductive. You have to accept the fact that doing real work in Pd may require a lot of externals. It's sad, but it's like that. I wouldn't use Pd if it didn't have externals. I care more about Pd as a language and as a means to learn. For my purposes, using externals is pointless, although I do appreciate all the hard work. #5. No interfaces or abstract abstractions (to control inlet patterns) I would like to know which inlets of a given abstraction are signals and which are events for the purpose of dynamic patching / autowiring. Bonus points if inlet metadata is available. With a bit of introspection, one could determine the name of the inlet, and thus autowire (dynamically patch) it to the correct binding (binding in my library, u_dispatch in RjDj). I work around this by enforcing a strict interface (as with RjDj) of two event inlets (hot and cold) where the cold inlet receives binding (dispatch) events. ~ objects just prepend signal inlets to the hot-side. Please first give an example of a useful use of the FlyweightPattern. Any given abstraction that requires a large lookup table obtains a reference (ie: the table name) of this large table without having to construct it by itself, it doesn't know how to create it, it just receives it... but every abstraction that requires this table receives the same one. This is much like a singleton. Otherwise it's a complete waste of resources. 6. Unfriendly and inconsistent type system (it is cumbersome in real use, > although I get over this by using [list]) > I once proposed alternate versions of [unpack], [select], etc., that had no type restrictions. There was a discussion on it. See : That would be great. In my uses I don't really need a [unpack a a a], usually by the time I reach a [pack] I already have a strong enough determination of what types I'm working with (my binding/dispatch is type-agnostic though), but it would be nice. Is this just ONE kind of InversionOfControl (IoC) ? I'd guess that there are several quite different manners of doing that in Pd, no ? But I have trouble reading definitions and tutorials of IoC. I probably have used a bunch of different IoC techniques in Pd and other languages already. Basically, an abstraction (or object) is given what it needs to function by a 3rd party. The abstraction in question only focuses on it's given task and doesn't know how to create it's dependencies. For testability and reusability, this is a fantastic pattern. So far I've been using constructor IoC (in creation arguments), but one could just as easily pass this information as a list to an abstraction's inlet. Max's [poly] and RjDj's u_makepoly~ objects are a very simple example of this. If you look at the structure of any given synthesizer voice in Pd, I'm sure you can think of other useful examples of this.

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. Every patch which uses [bypass]~ must have 1 signal inlet and 1 event inlet. Unfortunately, this interface can't be programmatically enforced. [bypass~] passes it's 1st two inlets to the sub-abstraction, while the 3rd is used to control [bypass~] I've attached [bypass~] and it's dependencies, have fun! ~Brandon bypass~-help.pd Description: Binary data bypass~.pd Description: Binary data mute~-help.pd Description: Binary data mute~.pd Description: Binary data defined-help.pd Description: Binary data defined.pd Description: Binary data ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

This is even better. If I could minimize the jumps around Y = 0.5 to -0.5 It'll be exactly what I'm looking for... or a start at least. Do you see what I mean now?

Re: [PD] Non-Linear Quantization / Bitcrush
I've attached my best attempt at recreating this effect, the attached PNG will be used as a reference. 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.

[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] Pd 20% idle CPU usage on MBP
This thread comes up every year or two, try running Pd with JackOSX instead of having Pd communicate directly with OS X. You should see the Pd process decrease it's CPU usage significantly.

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.

Dynamic patching is one of the best thing PD has going for it.

[PD] Dynamic Graph on Parent
Is there a way to dynamically adjust and enabled graph on parent (GOP)? I'm building some UI sequencer widgets and it would be preferable to dynamically adjust the GOP size given user input, say number of steps in a step sequencer (ie: an 8x8 vs a 16x16 step sequencer using the same abstraction). If this is documented anywhere a link to the docs will suffice, I'm unable to find any.

[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.

Btw, this seems to be a feature of almost all of the GGEE biquad coefficient externals. Check line 67 on highpass.c, bandpass.c, equalizer.c, and so forth.

Re: [PD] throw~/catch~ headroom
Andy, Great idea, I'll keep that in mind. You are correct, [throw~]/[catch~] does not contain a set maximum value. In the process of swapping out the cascading [+~] objects, I introduced a "feature" to the system which was causing the distortion.

[PD] throw~/catch~ headroom
Hey PD-List, Has the throw~/catch~ system been designed to have a different available headroom than standard [+~] and [*~] objects? I've been designing a few polyphonic patches and have decided to use throw~/catch~ instead of hard-wiring the summing bus. I've found that when the signal approaches 1.0, distortion occurs. Has this been designed as such for a reason? Cheers, ~Brandon ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] better tabread4~
Excellent point, don't listen to me! :) From your example, I'm assuming you're hinting at including the ability in this abstraction to switch interpolation schemes by enabling/disabling sub-patched tabread~, tabread4~, and tabread4c~ objects via inlet messages or creation arguments. In the end, I would probably only use a tabread4c~ type object in special circumstances given tabread4~ is good enough. So whatever you decide to do I'm sure it's going to be legit (as Pd rocks).

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?

Re: [PD] Pd-0.40.3-extended-20080221-macosx104-i386.dmg
Cool, that's good to know. I'll try again this week, and attempt to score all packages but libsndfile1. (I may have this Fink configuration backed up). As for Tcl/tk on 10.5, should I upgrade to 8.4.18, 8.5.1, or stick with what I have standard? By the way, thanks a bunch for building extended for Mac/Intel. Thanks a bunch guys.

The unstable stuff can be a little dodgy, but if the only thing that's missing is libsndfile1, I think everything should build ok. AFAIK, [sndfiler] and/or [readanysf~] are not automatically included in the build, and they are the only ones that need libsndfile1. As for the Pd-0.40.3-extended-20080221-macosx104-i386.dmg, I built that on my laptop, which is running 10.4.11. .hc On Feb 23, 2008, at 5:33 PM, Brandon Zeeb wrote: Excellent.

I'm using that, actually, and flac from darwinports. At this point, the builds fail at g_canvas.c... I can't even get Millers Pd to build yet.

Re: [PD] overall horrible performance in OS X
About the iTunes EQ, that is really funny. I just profiled PD while running the example patch, and you're right (see example 1 below). Using "Instruments" showed similar results, + a _lot_ of time spent microsleeping.

Your problem might be simply having the latest Macbook with its unbelievably shitty drivers. The Apple written drivers have gotten really bad lately - try to stick with ATI GPUs just to avoid Apple's in house Nvidia drivers for example.

Re: [PD] vline~ question
Ahh, okay. RIght, but if you scheduled that last message at 1800 instead of 59000 it would interrupt the full motion of the previous item. I was looking at these messages from the perspective of classic envelope generators (for example, the 'time varying' envelopes on the Roland XP-50/60/80 series for example, which are simply a set of volume points with associated slide times). So I get it now. The example below is a good one, hard off. If I were to make that envelope on the XP-50, for example, I would need a point in between to setup the long delay between 2000 and 59000, and would look something like this: [0, 1 1000, 0 500 2000, 0 57000 2000, 7000 6 59000( Thanks a bunch, ~brandon On Jan 26, 2008, at 1:10 PM, hard off wrote: > [0, 1 1000, 0 500 2000, 7000 6 59000( > | > [vline~] > > > > = > > start at zero, > > ramp to 1 over a 1000ms period, > > ramp down to zero in 500ms, 2000ms after initial bang, > > ramp up to 7000 in 6ms, 59000ms after inital bang > > > > > nothing gets 'cut off'..the 3rd digit just schedules a delay from > initial bang. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
