Damned, I feel old.

Did anybody have news about günter?
Or Tim Blechmann, Thomas Grill and other people that we don't see much on the

Re: [PD] [PD-announce] simplex noise sampling in Pure Data

[cyrille henry]

Hello,

This sound very nice!
The help file worth spending time to explore your examples.

And I just discovered that your 3d sound visualiser is click/drag-able!

Thanks for your work.
cheers

the [simplex~] external is available on Deken (including Pd64 builds)
and received a few updates since my previous message about it -
including optional derivatives output and optimizations for the
visuals in the help file.

obviously, the core of this is the noise algorithms, which were
implemented by stefan gustavson. the help file gives a few examples -
enjoy!

cheers,

Re: [PD] Gemwin vs [pix_snap]

[cyrille henry]

hello,
The image of the gem windows appear to be 1280x960.
pix_snap capture a 640x480 image.
Are you sure that the gemwin is create with a dimen of 640x480?
Maybe there is a compensation somewhere because of high resolution apple screen.

can you send your patch?
cheers

Dear Lists,

I have an old patch I want to revive and the following problem:

I have a gemwin with certain dimensions, say 640x480pix, and I want to record 
it using [pix_snap]+[pix_writer]. I use the same dimensions for pix_snap but it 
is only capturing the left bottom corner of my gemwin. The resulting pix has 
the correct dimensions, also 640x480pix.

I use macOS 14.4, pd 54.1,
GEM: ver: 0.94.git v0.94-973-g1659d628b
GEM: compiled  on May 23 2024

Here are two pix showing the problem:

While we're at it, as I only know about macOS, let me ask about windows and 
linux...

So, Windows 11, the current version, is only for 64 bit architectures, right? 
so one cannot install pd 32 bit on it.

As for Linux, is there any most recent version only for 64-bit architecture?

debian is known to run on multiples architecture :
https://wiki.debian.org/SupportedArchitectures

anyway, you need a 64 bit OS if you want to address more than 3Go of memory.

I see, not being well versed, I see I'm again confusing 64-bit architecture with 
double precision. And I'm still confused on what "CPU-architecture" actually 
means. Let's see if I get things straight.

Older macs with intel chips can run two different architectures: *i386* 
(Intel 32bit) and *amd64* (Intel 64bit). This depends on the OS and the last to 
allow i386 was Mojave (10.14). Newer arm64 is obviously only 64bit.

I'm positive this is what it is, but it still strikes me as a bit uncanny that a 
computer can have more than one architecture, as my intuition would tell me that the 
architecture of my chip can only be of one type. So I guess I don't really get the 
concept of "cpu-architecture".

Anyway, things like this should be made clearer for dummies like me in the 
manual and stuff.

depends on what you mean by "can".
technically they could.
practically, Pd64 will *not* load an external that ends with .pd_darwin.
see the mailinglist archives and the github issues for a lengthy
discussion why it is like this.

sure, why not?
the "double" floattype has been around for some time.
a quick wikipedia check shows that one of the first (C)PU to implement
IEEE 754 (the floating point standard that defines "double" floats as we
know them) was the Intel 8087, a 16bit processor (and famous
co-processor for the 8086)
It would be capable of running Pd64 (".cpm-x86_16-64.so").

Re: [PD] Solving the three-body problem [1] with pmpd and GEM, anyone ?

[cyrille henry]

Hello Winfried,

It's really easy to simulate this problem.
Benjamin Wesch send me a patch off list. I added it to mine, so here are 4 
different way to go. (using mass2d, pmpd2d, pmpd2d~ and pmpd3d~)

The biggest challenge is finding initial conditions that did not result in a 
very fast divergence of the masses.

Re: [PD] [gem] trigger in gemchain

[cyrille henry]

Hello Peter,
Thanks for your answer.

sorry if the unconnected [t a a] mislead you.
The question is not how to apply a texture to 2 squares. The question is why 
the texture is not apply to both square?

The 2 side of the patch create exactly the same gemchain, and should behave 
identical.
They are not.

[trigger] are usually transparent in a gemchain. This is the only 
counterexample I am aware.
It also mean that you can't adapt my L-System example 
(02.Advanced/21.basic_LSystem), or Claude recursion tutorial 
(example/13.recursion) to use texture.

So, I think it's a bug, and I'm wondering if this behaviours change, since I 
never experience it.
but I'm waiting for Iohannes opinion.

Here is another example, using [gemlist] that should have worked, imho.

Cheers
C
P.S, I keep this thread to the list.

Hi

I checked your patch, and as i could see there where some connections

I could apply a texture to 2 squares with the texture-chain split by
[t a a]
see the attached file

all best,

Re: [PD] [gem] trigger in gemchain

[cyrille henry]

hello Jonas,

There is no pix_separator in the patch, but it act like there is one.
and (I think) it should not.

thanks for your answer,
cheers

P.S : I answer back on the mailing list

Hi Cyrille,
I remember [pix_seperator] to help in some situations, without ever have fully

hello,
I always assume that you can split a gemchain using trigger. Lot's of my 
patch are using this feature.
I just discover that it's not working with pix_texture.
I don't know if it's a bug, or if there is a good explanation.
Can someone have a look a the attachment, and tell me why the texture is 
not display on the left square?

thanks

Re: [PD] vcf~ producing output without input for 0Hz cutoff?

[cyrille henry]

I don't think it's weird for a lowpass filter to go under 20Hz. They are not 
restricted to audio signals.
I use them a lot to smooth control signals, or to replace line~.
(I really hate line~ to control sound amplitude or preset transition, it's way 
too robotic)

cheers

and you got a strong DC component over there :)

anyway, it also seems weird to have a lowpass or a bandpass going as low as in 
the 20hz range. If you wanna do it just so it fades out to silence, you need a 
DC filter, something like a [hip~ 5] object, so when the lowpass, bandpass gets 
there, then you have nothing.

Well, let's simplify a bit, forget all the filter complexity (Q, slope, 
definition of the cutoff frequency...).

Let's just say that the output of a lowpass filter cannot move faster than 
the cutoff frequency: a 1Hz filter output cannot move faster than 1Hz (so it 
can't go back and forth in less than a second or so), a 1kHz can't go back and 
forth in less than about 1ms, etc. The output of a 0Hz filter can't move... at 
all. When you set the cutoff to 0Hz, the output freezes to its current value. 
It won't magically decay to 0.

Hey, if you set the framerate of a movie to 0 frame/second, it will just 
stop, and will show the same image forever; it won't fade to black!

Thanks Antoine,

Why does a lowpass filter, that has a cutoff frequency of 0Hz imply that
it's output is constant?

I will describe the problem again hoping that I will understand it
better myseld:
I have an oscillating input signal that has some DC offset (unipolar
sawtooth from phasor~). I fade this signal's amplitude to -inf dB using
[line~].

I also fade down the filter cutoff (defined as the -3dB point of the
filter curve) from 400Hz to 0Hz. The filter will then continue to 
produce an
non-decaying output.

If I fade down the filter cutoff down to only 1Hz, it's output will 
decay (somehow
counterintuitively to me). This is the part I don't get.

I understand that vcf~ is a resonant filter, and it can have a gain
greater 1 around the cutoff frequency, especially for high Q values. The
above behavior can also be observed for Q=1.

Thanks for all hints!
Peter

[PD] help files path, difference between startup flag and pdsettings

[cyrille henry]

hello,
I experience a strange problem I can not understand.

for (pmpd) development purpose, I don't want to install it from deken, but use 
my local build.

binary are in ~/pd/git/pd-pmpd/build
help files are in ~/pd/git/pd-pmpd

when I start :
pd -noprefs -path ~/pd/git/pd-pmpd/build/ -path ~/pd/git/pd-pmpd

everything is fine.

but it did not work as expected using pdsettings.

I remove the preference file for test purpose, to start with an empty file.
I added the 2 paths.
My preference file now is :

audioapi: 1
noaudioin: False
audioindev1: 0 2
audioindevname1: sof-hda-dsp (hardware)
noaudioout: False
audiooutdev1: 0 2
audiooutdevname1: sof-hda-dsp (hardware)
audiobuf: 25
rate: 44100
callback: 0
audioblocksize: 64
midiapi: 0
nomidiin: True
nomidiout: True
path1: /home/chnry/pd/git/pd-pmpd/build
path2: /home/chnry/pd/git/pd-pmpd
npath: 2
standardpath: 1
verbose: 1
nloadlib: 0
defeatrt: 0
flags:
zoom: 1
loading: no


My problem is that the help file is not find :

tried /home/chnry/pd/git/pd-pmpd/build/pmpd.linux-amd64-32.so and succeeded
tried /home/chnry/pd/git/pd-pmpd/build/pmpd-help.pd and failed

tried /usr/local/lib/pd-externals/help-pmpd.pd and failed
tried /usr/local/lib/pd/extra/help-pmpd.pd and failed
sorry, couldn't find help patch for "pmpd"

pd search only in the binary path, and in other standard paths, but not in the 
path declared

the solution is to add in pdsettings :
flags: -path ~/pd/git/pd-pmpd

I understand that having binary and help file in different path is not 
expected, but why do pd behave differently using path in .pdsettings, than 
using path in startup flag ?
Is that expected, or is it a bug?


pd 0.54.1, compiled from source, ubuntu linux

the SC spring is not a simplified model, it's the standard model. (you can

if you put 1 mass and 1 spring, you have a 1st order filter.
if you put two 1st order filter one after the other, you have one 2nd order

Re: [PD] spring modeling/scanned synthesis

[cyrille henry]

I know a little bit about filters and will try to investigate more. I've been 
avoiding physical modelling for ages and it seems its finally time to dig in :)


Here is the most simple usable structure : a mass and a link.
it look like a 2nd order resonant filter.
now, the challenge is to find the equation that compute K and D from frequency 
and attenuation time.

being able to say what it is useful for in their forum... but I ported the 
bouncing ball and it seems something way more fun to play with.

I don't understand what is a "spring link motion".
Masses moves according to newton law.
Lot's of different behaviours can be modelled with MSS model...


 as I said and each mass represents a point in a wave table, right?

that's the canonical definition, but you can also put the force applied to the 
mass in the table. or the velocity.
or link length etc

 Also, you have a chain of masses and the last one (the last point in a table) 
connects back to the first one, huh?
that's one possibility. You can also attach both end, like in a guitar, or only 
one, like in an organ pipe.

You can use a membrane better than a string, a random network, make different 
kind of connection between masses, or using a non linear connection between 
them.
You can use a virtual bow, or an clarinet hip to create the movement.

And there are a million more possibility.


you can have a look at few of chdh work :
https://vimeo.com/130239547
http://chdh.net/video_spin.php#;
this is 100% scanned synthesis.



Anyway, just had some time to look back on this. And I've been checking some 
Spring-Mass-Systems.

  I was checking the code of the Spring class in SuperCollider, I was able to port it 
to Pd. See 
https://github.com/supercollider/supercollider/blob/db7eed2a17c361503dbc7f70a557874b6001e3cd/server/plugins/PhysicalModelingUGens.cpp#L77

 note the code says

/// some basic physical modeling ugens - julian rohrhuber 1/04
// these are very simple implementations with cartoonification aspects.
/

And in fact, I was checking this other mass spring damper system implemented in Max 
(that I also ported to Pd) and it seems a much more robust system with more 
meaningful parameters based on actual physical quantities 
https://www.youtube.com/watch?v=2rFkZD51mT8 
<https://www.youtube.com/watch?v=2rFkZD51mT8>

How do both compare to pmpd? 


you probably noticed that they all use the same equation,
The 1st is just a very basic implementation : it's not possible to define a 
non-linear link for example.
The 2nd one solve them in a very simple scenario : 1 mass and 1 spring. So it's 
not possible to create other network.
The beauty of mass/spring system is that it provide an easy way to compute a 
very complex movement, when it's not possible to find analytic solution.

Thanks to pd flexibility, pmpd offer all brick you need to create complex 
movement.
But if you just want to play with meaningful parameter without understanding 
the physics, then pmpd is not for you.
anyway, pmpd was not about sound synthesis, but about control data synthesis. 
It is now possible to generate the same stuff with ~ objects, but you have to 
see it as a way to experiment. It's clearly not a ready to use PM synth.


Is there any canonical model or it's one of those things that is a matter of 
taste and subject to things like desired efficiency versus realism? Do any of 
you know of more models out there in Pd or other computer music systems such as 
Csound, MAX, etc?
there are lot's of software dedicated to MSS, the equations are all about the 
same.
But physical modelling is broader than MSS.



I've also been having fun with Sine Waves with exponential decay envelopes. Like with the [decay~] object from ELSE which is like the Decay class in SC - a one pole filter that you set a "t60" decay time in ms (time it takes to decay 60dB). This way you have a good control on the frequency and decay time. Another option is to just [resonant~] from ELSE, which is also like SuperCollider's Ringz.ar, excited by impulses. This is a resonant 2nd order filter that "rings" for a given decay time and frequency. How does this compare to "Spring Models"? 


you can easily model a 1st or 2nd order resonant filter using pmpd audio 
object. But you will control them using damping and rigidity, not frequency and 
characteristic decay time. They are linked, an abstraction can switch from 1 to 
the 2nd, but that's not the aim of pmpd.

How is Spring "springer" than creating damped oscillators with [decay~] and 
[resonant~]? Also, for reference, I found this in Pd as well 
https://www.youtube.com/watch?v=zW7y5yb0YWQ <https://www.youtube.com/watch?v=zW7y5yb0YWQ> 
that I am relating to [resonant~

it? When can we have it if so?

I'm working in a new pmpd version that include the new pmpd2d~ and pmpd3d~. 
Nothing important change for the rest.
pmpd source are on my github :

https://github.com/ch-nry/pd_pmpd



They use the simple native Spring class for it, and I've been having my eye on 
that one, maybe one day including Spring and Ball/TBall into ELSE as well 
(spring~ and ball~?), cause it also seems like a fun thing to control several 
things in a patch.

You will face problem with spring~ and ball~ because of buffers, you better go 
for spring and ball.
and since a spring should also include damping element, let's call it "link".
And the ball have a null radius, they usually are called "mass" in the physical 
modelling world. (I don't know why SC try to be original and change the naming convention 
usually used)
So, this look a lot like pmpd, and after working with if for more than 20 
years, I can confirm that this is very fun!




Now let me see if I can get the main principal, is it like you have wave table

Hello,
If you want to try scann synthesis, I suggest to try pmpd. specially 
example 47.


Running this in Extended now, it looks amazing. Do we really need Gem though?


You need Gem to run this pmpd example, but you can easily adapt the patch to 
run it without Gem.

 I figure it is just for displaying the array which is also a model of a 
string, right?
yes, but since this string use 2d physical model (X and Y movement), you need 2 
array to display masses displacement and it's not very friendly.

Perhaps one could use a Data Structure array instead?
yes, sure! This example was made before data-structure was a thing, but you can 
adapt it easily!

Or just nothing at all to just focus on the sound.
from my experience, for complex movement and shape of the string, having a 
visualisation help a lot. But it really depend on the way you play with it.


By the way, how do we set the frequency in your example? It seems fixed.

This is Pd, of course you can change the frequency! just adapt the patch to do 
whatever you want!!!
The patch is very simple : everything is obviously in [pd corde] (sorry for my 
french). [pd sound] is where the masses position are put on a table. [pd 
table_read] is where the tableread4~ object are located. You just have to 
change the phasor frequency...



As for pdp, it seems it tries to use the webcam or video sources and I don't 
understand why.

In fact I know nothing about scanned synthesis and I just ran into it by 
accident when reading about vector synthesis in wikipedia, and I even read the 
original paper but I couldn't figure it out much yet.

It sounds at first some kinda of wavetable synthesis but it is clearly physical 
modeling, right?


well. the article describe it as :
"The essence of scanned synthesis is to use a slowly
vibrating object whose resonant frequencies are low
enough so the performer can directly manipulate the
object's vibrations by motions of his body and to scan
(measure) the shape of the object along a periodic path by
a periodic scanning function whose period is the
fundamental frequency of the sound we wish to create."

So, yes, a wavetable synthesis with "slowly" updated table by an algorithm that 
you can interact with.


According to this definition, pdp_scan~ is not really a scann synthesis. But 
it's not very far, since it scann an array at sub-audio frequency.

The only example in the article is about a string, but one can imagine lot's of different 
topology of the physical model, lot's of different way to interact with the model, and 
lot's of different way to "play" the shape of the model...




Would love to dig more in it and provide an external myself but it looks quite 
complex...

all you need to explore scann synth is the pmpd lib and tabwrite / tabread~
A scan synth external will be more limited that what pmpd + pd can already 
offer.

still from the olde sourceforge SVN?


quickly commenting on the build that cyrille posted here now, too: i
took the code from https://github.com/avilleret/pd-pmpd since
https://github.com/ch-nry/pd_pmpd forks from there and antoine
villeret also put v0.12 on deken afaict.


Yes, Antoine took the code on the old SVN and put them on github, manage to use 
github to create binary for few platform.
I forked Antoine repo to keep the code on my side.
There is no need for 2 repository, I'll see Antoine next month and I'll try to 
clean that with him.

 

i'm curious to see whether the reported crashes are related to the
build (i experienced some crashes with the example patches on an m2
mac here, too - although all objects work for me if i test them
separately). 


I'm really surprised by the crash. The code is very basic (no memalloc, no 
external dependency : just few mathematical function).
Just like Peter, I can't reproduce them.
So, this really need to be investigate.


in any case, i would be glad to see a more *official*

macos arm or universal build on deken - i admittedly mainly built this
to work with it here myself. thanks for the tests and involvement!

Since you provide the only binary for mac arm I'm aware of, and unless you have 
an objection, I'll put your build on deken to be the official build!

Cheers
Cyrille

hello,

Benjamin Wesch did compile pmpd for OSX (arm and x86).

Before putting them on deken, ca anyone test them?

Hi list,

often when I use [line¨] to make frequency glissandi, the point when the
ramp starts, and the point where it ends, appear as very sudden events
to my ears. I am wondering if there is an easy way to gradually speed up
the ramp when it starts, and slow it down before it reaches its target
value?
The only way I can think of so far is to model such a behavior with two
masses connected by an elastic link using the pmpd library. But a
vanilla way would be very interesting too!

Thanks in advance for all ideas and pointers!

Re: [PD] how force [pix_film] to use the QuickTime backend on Windows

[cyrille henry]

if you put pd log verbosity to 3, you'll see in the log the backend used by 
pix_film.
On my computer, I've got :
[pix_film]: quicktime4linux support
[pix_film]: image support
You probably have others.

According to pix_film help file, you need to send a "loader" message to use 
only a specific backend.
More informations about specific backend can be found in the help patch.

Re: [PD] Rectangle object does not understand [width 7( message

[cyrille henry]

hello,

ok, thanks for the screenshot. (i still think a patch is easier to share than a 
screenshot)

Since nothing have been changed in this part of Gem this last 10 years, it is 
safe to assume that the difference between your 2 computers is not related to 
Gem.
So, as Iohannes say, the problem is probably on the openGL implementation, 
certainly because of WSL.
I never had this problem on a ubuntu computer with old intel GPU.

I'm sorry , but I have no solution to offer exept not using WSL

I hope it clears your doubts.

it can be a patch problem, specially if your patch is very complex. Please, 
create a simple patch (gemhead / rectangle and the witdh message), that

GEM: compiled  on Jan 12 2023

Can you send the test patch you are using, or try the curve-help file and tell 
us if the width message is working?

if it's not a patch problem, it's the hardware that can't interpret this 
message. What is your GPU?

i'm not sure what you mean with "compiling Gem from deken"...deken is a
way to deliver pre-built binaries, nothing to compile.

what exactly do you mean with "does not understand the message"?

I am still trying to calculate (unwrapped) phases from cartesian complex

Thanks!

Hi list,

trying to work on phase angles of spectra I am looking for an easy
example with actual Pd objects how to convert a [rfft~] output from
real and imaginary to magnitudes and phases, eventually unwrap phases if
required, and then convert magnitudes and phases back to a cartesian for
[rifft~].

I know about the Dudas/Lippe pvoc tutorials for MaxMSP but can not find
much in Pd's documentation. Perhaps I am missing something?

Thanks for any pointers!

You make it sound like it behaves like UDP where some packets are

_serial_

doesn't get randomly lost during transmission.

If you fill the buffer faster than you can empty it, at one point the
buffer will be full and then you will lose data.
you CAN lost data on serial connection.


I see. Do you know how [comport] handles buffer overruns? Does it block
Pd? Does it drop new data and print an error? Does it silently drop
data?

I don't know.
But I was more thinking about data lost in the arduino side.

Of course, data still can get garbled during transmission due to

Hello Rick,
This sound like a problem in the serial connection, maybe the arduino misses

Have you tried to slow down the messages you send (not sending them all on the

Have you try to configure and use all pin interdependently?

Hello list,

I am helping someone use pd with an arduino mega.  They would like to use all 
of the digital output pins.  I’ve used pduino in the past in this way and not 
had trouble, but I seem to be bumping into something now.

I started by using the arduino help patch.  StandardFirmata sketch on the Mega. 
 Connection via usb works fine.

I set all the pins to output by sending "pinMode 2 output” -> “pinMode 45 
output” messages to the arduino object. No errors.

Then, I use the messages “digital 2 1” “digital 2 0” -> “digital 45 1” “digital 
45 0” sent to the arduino object to check the pins.  When checking with a 
multimeter I am not able to get output from pins 2-7.  I do get output from 8-20.  
Between 20-40 some pins work and others not at all.  Other pins will turn on but 
not turn off.

Checking the pins using a simple blink sketch shows all the pins working fine.

Any advice would be greatly appreciate!

Cheers,
Rick

[PD] Fwd: Shared memory for [pd~] processes

I answer back on the list...

I think I did not compile it in the last 10 years, but A.villeret did and he 
use github magic to compile it on various platform.

code is here :

updating this file will certainly do the job for a mac arm64, but I don't have

Hi all,

I hope this is a quick question: is it possible for a [pd~ start foo.pd(

job for ‘-nogui’, but I’ve had no luck with that (and where would it go, if

Thanks for any enlightenment,



The answer is in pd~ help file!


"pd~ start" takes as arguments
any startup flags you wish to send the sub-process. For example, specify 
"-nogui" to
stop the sub-process's GUI from appearing.

Re: [PD] bang [gemhead]?

[cyrille henry]

hello,
The timing to bang a gemhead is very specific. You need to bang it after the 
beginning of the rendering process and before the end of the rendering process. 
(In short, you need to use an other gemhead)
If you want to sync our render on a ~ object, the easiest solution is to use single 
buffering (with message "buffer 1" before the window creation).

This will open a can of worms depending on what you want to do, but let's solve 
1 problem at a time...

An other solution is to set Gem fps to the frequency of the output of the env~ 
object (you can easily compute it).

Cheers

Yes, it's exactly that--there's always at least one shared piece of
information that's hard-coded in both patches, if you want to
communicate solely through shmem.  It's trivially extended though.
All processes agree to read from one chosen shmem ID of size 2 on
startup and know that it contains the ID/size of a variable-length
shmem that's now known.  Before you know it, you're writing a whole
protocol.

What's the best method for callbacks from a process that has completed
its task and has data ready to be staged out?
The toplevel process has to be able to be reached from multiple
processes--so that seems like it should just be a udp port.  Unsure on
this point, though

Best,
Chuck

My conclusion there was that shmem can be used for asynchronous
inter-process communication with minimal risk to real-time. 

it can also be used between 2 synchronous process!

 It's very

good as a fundamental object--it does not block, it does not
synchronize.

that's the aim!


Notable limitations:
1. Every process needs to know/use the same size for shmem ID's.

is that a real limitation?
Do you have a practicable example where one need to share memory of different 
size?


2. Once allocated, a shmem cannot be re-sized.


There is an allocate message now!
It allow to change the Id and the memory size.
But Antoine have problem compiling it on windows, so the last version is only 
available in deken for linux and osX.
I'll be happy if anyone else want to gives a try at a windows compilation...


3. Writing to/from an extremely large array all at once poses a risk
to real-time.

yes, obviously, moving data from an memory position to an other need time.
It's far from ideal, but in this situation of "extremely large array" you can 
spread over time your read/write.

Cyrille



I'd like to write a pair of management abstractions for using fast
forward and shmem, then, that make it easy to stage in/out large,
variable-length data

Anybody else have best practices for IPC when using fast forward?
Having a listener on the 2nd process between computing sprints in the
"fast forward" process completely changes how I can do things.

other: is there a good way to start/stop processes other than
[ggee/shell]? cross-platform?

My impression is that the OpenGL side is all 32bit float. I tried
'quality 1' to [pix_texture] which does (from what I see) linear
interpolation. And I also tried bicubic interpolation with a shader
written by Cyrille Henry from 2007. The shader code is using type vec4
internally and GLSL spec says that this is 32bit float [1].



Computation is done with 32 bit float, but that does not mean that the result 
is stored as a 32 bit float...
The GPGPU example shows how to keep precision in texture (but not to render in 
high precision).

In your example, you only need the gem windows to be rendered in 10bits/color. 
Unfortunately, I don't thing there is flag or message to allow this for now. 
You should create a feature request.

As Claude says, adding dither is a good way to mask this problem.

[PD] pd~ crash with broken pipe and difference between "pd~ start -nogui" and pd~ with gui

[cyrille henry]

hello,
I've got some problem with pd~.
I'm using pd 0.51.4 and pd~ version 0.54.

It look like pd~ scheduling have been changed from what I was used to.

now, pd~ with or without gui did not react on the same way. And I also experience crash 
with "broken pipe" error in various situation.

See attachment for better explanations.

Can someone please confirm this problem?

What is the best practice using pd~?
The only solution I found is to have a [loadbang] -> [dsp 1( -> [send pd] in 
the main patch and in the subprocess patch. This way, things works the same if pd~ is 
started with or without gui.

Re: [PD] list of Pd forks?

Le 06/10/2021 à 16:46, Alexandre Torres Porres a écrit :

hmmm, I thought there was a pretty simple and straightforward and "universal" definition of a fork, which would be 
basically a parallel (independent) development. Maybe there's just no "official scientific definition"? Wikipedia 
 says "/a project fork happens when developers take a copy of 
source code from one software package and start independent development on it, creating a distinct and separate piece of 
software/", one of the referred sources on wikipedia  says 
"/In general it is assumed that a software product evolves within the authoring company or group of developers that develop 
the project. However, in some cases different groups of developers make the software evolve in different directions, a situation 
which is commonly known as a fork./"


[...]

And, well, I can't consider MAX as a fork of Pd or the other way around. I 
heard that MSP objects were first based on Pd signal objects, but that's not 
really a fork of the software, more like appropriation - or stealing :)


The fork is not about Max, but about MSP. Last time I start Max/MSP (v 3.1), the startup 
log says "MSP based on pd by Miller S. Puckette"
I think it fall under the fork definition on the beginning of your mail (MSP use pd code, and is 
now "developed independently" and is clearly a "distinctive piece of software").
MSP is probably the most famous pd fork!

(and electronic-art fork I mention in my previous mail fall also in this 
definition)

Anyway, maybe you are more looking at open sources fork of Pd ? (many closed 
sources fork will never be identified)

Hi List,

I want to share memory between several instances of PD running on separate 
reserved cores. I've tried the share-mem lib, but it has a very high overhead.

Since I am writing custom externals for the puredata patches, I have started to 
include writing the data to be shared into files on a ramdisk. It does work 
quite nicely, but I am wondering whether some more elegant solution could be 
done using the Memory-Mapped Files, or are there any other simple and fast 
solutions around?

Has anyone on this list experience with this? I don't actually need to share 
large data sets, mostly it's just bytes that indicate the state of the patch. 
Network based solutions have proven to be too slow.

These patches will run on raspberry pi.

Thanks!

Re: [PD] Multiple audio outputs on a single-board computer ?

[cyrille henry]

Hello,

I bought one octo for a project thanks to Thomas experience,
It worked great at home when I plugged it on my mix table, but when I install 
everything in the project final destination, plug the sound-card on an 
amplifier, switch everything on: the sound card did not works anymore.
I tried to contact someone at audioinjector, but I hardly have answer to my 
question. IT'S THE WORST CUSTOMER SERVICE EVER!
It's been 2 week, my project is on standby, I'm still stuck with a broken sound 
card.
So I don't recommend this soundcard to anyone and I consider buying a gigaport 
instead and throw this crap away.

unless someone have a suggestion to a cheaper 8 output soundcard for a RPI 4.

Cheers

Dear all,

I haven't posted anything on this list in years.
I'm trying to build a system to play several sound files in a loop,
each around 2 minutes in length, all at the same time. By "several" I
mean 10 to 15 different files. While I'd have no problem making a Pd
patch to achieve this, I have no idea what hardware I could use. I
have a limited budget, and I was planning on running Pd on a Raspberry
Pi (or similar single-board computer).

Is there any cheap way of outputing than many channels from a single
(a couple of) RPi ?


How many are 'many' :-)

If it's <= 8 channels and you don't care (too much) about latency you
could check out a cheap '7.1' USB card (these can cost less than 30 euro
online) and if it exposes 8 writable inputs via jack that could work.
The physical outputs of these are, of course, unbalanced and in couples
so you'd need to do some cable splitting and then maybe have a mixer
nearby...
I never did this on the RPi but I _did_ something similar with a cheap
5.1 usb sound blaster hooked to a laptop in the past.
I'm assuming, of course that each file would 'consume' just 1 channel...

YMMV.

If you want more than 8 output channels it will be hard to stay 'cheap'
(which of course depends on 'how much' is your limited budget), and then
- of course - you need to check linux compatibility (i.e. if they are
'class compliant'...)

My two cents,

Lorenzo.

however, as soon as a number is greater then binary 27 bits the last byte stays

Re: [PD] pd~ -nogui process with Gem [scopeXYZ]

[cyrille henry]

hello,

you need to send a message [pd~ start -nogui patch.pd< to your [pd~] object so 
it open your patch without gui.

Since pd and pd~ are synchronised at sample rate, if one of the process lag, 
the other will also lag. So it's not a good way to separate Gem from the audio.

Solution are :
- reduce Gem framerate so it did not create audio dropout
- use 2 puredata process that are not synchronised, and pass the audio from one 
to the other (using shmem by example), but Gem will not be faster, and you will 
get about the same frame as the previous solution
- use faster hardware


you can search pd archive here : https://lists.puredata.info/pipermail/pd-list/

Hi. I find it difficult to search for discussions related to pd~ because Google

hello,
I've got a problem with pd~ on one of my patch, on a specific computer.
The patch works on all computer I tried except one. On this computer, other 
patch using pd~ works great.
(all computer run different ubuntu flavor, and pd (vanilla) version)
The computer that cause this problem is a 20.04 ubuntu mate, using pd 51.4 
compiled from source

when starting pd~ with the -nogui flag, after few second, pd~ stop working and 
an error appear in pd log : pd~: Resource temporarily unavailable
everything is normal without the -nogui flag.

The patch is to complex to share, and anyway it's working on most computer...

what could cause this problem? what should I try to solve it?

if you want to do C and D only depending of the result of B, the best "pd"

BA

[test result]

A feature not existing because of the difficulty of adding it would be one 
possible answer to my question, so I checked the code before coming here and it 
turned out to be the expected for loop.

 >you still have to come up with an example where it gets so ugly it's

Why? I never said it is hard to bear, I said it was easy enough to work around 
and implied that being able to break out of trigger would make it neater and 
more readable, and at times it would. Most things in life would probably be 
unbearable if we waited until things got difficult to bear before even asking 
why.

 >what are the chances that while you clean up the patches so they are

It is in cleaning this patch that the question arose, but I never said I needed 
it, I did not request a feature. I plainly stated that I suspected the fault 
was with my understanding and not pd. Most languages give you simple ways to 
break out of a sequence of events, but pd seems to treat it as jumping off a 
cliff. As I said in my first post, I am asking why, not how to do this, just 
trying to understand the logic of pd so I can use it better.

on a more general note:

it would be great to have something like a public [GEM-shader] archive, 
probably something like pdpatchrepo.info

should we open a new category there ?
or maybe that already exists and i missed it ?
anybody else on this list that has some GEM shaders to share ?


lot's have already been send on this list!



i have the feeling that a lot of people using GEM "roll their own" shaders  (i, for one, 
did) and it would be a great thing to join forces, so one doesn't have to reinvent the wheel when 
looking for a simple "brightness/contrast" shader ...

funny, this one can be found in 
pd/help/browser/Gem/exemples/10.glsl/01.simple_texture.pd




my own technical knowledge about shader scripting is close to non-existant, but 
i succeeded in adapting stuff found on the net, so that it loads as a shader in 
GEM. basic stuff only, mixers etc ...


it's quite easy to use shader from shadertoy, at least when it's a single pass 
rendering.




since csaba's original post talks about cropping/rotating a texture created 
from a MATLAB shader (would be also great to share !), one possibility could be 
to feed this texture into another shader.

or modify the curent shader!



i tried my clumsy hands on a quick and dirty adaption of MAX's [rota] shader, 
and even though it loads succesfully, it's obviously wrong as the resulting 
texture seems to be 1x1 dimension. i'm sure the error is somewhere in the .vert 
part.

or texturing mode (rectangular or not)

hello,
I had a problem with hidpi screen on linux (ubuntu mate, 20.04):

everything looks good using a 4K screen, everything is also ok when using only 
one 1920x1080 screen, but pd (and only pd) use very big font when using both 
screen in the same time.
The solution was to set dpi with : "xrandr --dpi 80" in a terminal
this fix pd resolution.
I just send this information here since there are few mail about hidpi in this

hope it will help other

Re: [PD] fast way to convert two 8 bit data to one 16 bit data in big lists ?

[cyrille henry]

hello,

if you don't mind using eternals, you can put all data in a table, then use 
tab_downsample from nusmuk_utils to create 2 tables with MSB and LSB, then the 
iem_tab library will provide the other mathematical object to multiply 1st 
table by 256 and add the other one.
It should perform very efficiently.

iirc, there's some logic built into Pd to prevent double loading of plugins.

(this does not effect the built-in deken, as it comes under a slightly
different filename and/or because the "built-in plugins" bypass the

Re: [PD] deken and pd -noprefs

[cyrille henry]

Thanks for your mail. I do use pd 0.50.0, but you are right: it's not the same 
deken version with or without the -noprefs flag.

the old deken plugin was in ~/pd-externals
the new was in ~/Document/pd/externals
I removed the old plugin, now pd find the new one with or without the -noprefs 
flag.

I was not aware that ~/pd-externals was a default search path even if it's not 
listed in the preference dialogue and that this path was used even with 
-noprefs.

There is still something strange : When using pd -noprefs now that I remove the 
old deken, pd can still find the new deken, so ~/Document/pd/externals is still 
in the search path. Since this 2 paths are searched with the -noprefs flag, why 
did the new plugin did not overwrite the old one, just like without this flag?

Anyway, it's working now.

thanks for your help

i'm on ubuntu linux 18.04
pd 0.51.0


are you sure about the Pd-version?

my interpretation of the issue you see is:

0. there has been a single change to the deken package format; the
minimum deken version required for the new package format is deken-0.3.0.
luckily, the deken-server knows about this; if it detects that you are
using an older version of deken, it will always suggest to upgrade deken
first.
it  tries hard to nudge the user into upgrading deken (without actually
forcing them). this is why you get a capital letter warning "MINIMUM
VERSION REQUIRED FOR NEW PACKAGES".
this is really true: if you are using an old version of deken, you will
not see any new-style packages (because deken cannot ectract them anyhow).

1. you are using an older version of Pd, that comes with deken<<0.3.1
(sidenote: Ubuntu-18.04 comes with Pd-0.48-1 preinstalled [1]; Pd-0.48-1
includes deken-0.2.4 [2]

2. a while ago, you have followed the instructions and installed the
updated deken package.
now updating deken does not overwrite the existing source code in the Pd
application folder, but instead installs a gui-plugin (in the usual
path, where deken installs stuff).
when you start Pd, it will first load the included (outdated)
deken-plugin, and then load the plugin (there's a version check that
prevents an older plugin to overwrite the included one).
so you end up with a new and shiny deken plugin that can find and
install all the nifty nusmuk packages.

3. however, when starting Pd with "-noprefs", you are telling Pd to not
take the "usual" extra-folder into account, where you (or rather: deken)
installed the updated deken-plugin.
this usual extra folder is probably "~/Documents/Pd" or some
self-defined folder (as the usual-usual extra folders like
~/.local/lib/pd/extra are searched regardless of the "-noprefs" flag).
so the updated deken-plugin is neither found nor loaded, sending you
back to square 1 and you can no longer find the new-style deken packages.


there's a couple of ways to fix the problem:
- include the /path/to/the/deken-plugin/ manually in your start-up flags
(e.g. ~/Documents/Pd/deken-plugin/, so you don't get the full
~/Documents/Pd/ search-path but only the portion that you want)
- manually include an updated version of deken into the
application-specific extra folder (it should go e.g into
/usr/lib/pd/extra(deken-plugin/)


to conclude: i don't see this as a bug in deken (nor Pd).
(esp. there's nothing *fixable*; new versions of deken (and Pd, which
include a newer version of deken) don't have the problem.

Re: [PD] [GEM] output gemwin to video file workaround using ffmpeg on macos

[cyrille henry]

hello,
The open GL rendering is made in the GPU. grabbing the images by the CPU in 
order to compress them and to record them in the HDD is a slow operation.
I think some software are able to compress the image in the GPU in order to 
grab a smaller file, but Gem don't.
So, there is not a lot's of solution, and you already found them.

I use pix_record when I need a correct quality of a small video. I use mjpa 
with good result.

When I need better quality, I use pix_writer. Usually this can not be made in 
real time. I.E : I create a process that render exactly what I want, without 
human interaction. (For live performance, I record all human interaction in 
tables or texts file during the performance, then I use this data to play again 
the same performance)
Then, It's possible to record both image annd sound in the same time. Even if pd will not 
be sync with real (external) time, the time inside pd will still stay consistent. I.E : 
even if there are lot's of audio dropout and the recording fps is 1/2 of the real fps, pd 
will still record a perfect audio file that will be perfectly sync with the video. You 
just need to start the audio and video recording with the same "bang".

Hi everyone,

Is it possible to grab the OpenGL stream with ffmpeg and save to a video file? 
If so, could anyone point in the right direction as to how to capture the 
stream opened by Gem?

The reason I ask this is that I am looking for ways to render video frames to a 
file and I have not managed a good result using neither [pix_record] nor 
[pix_writer].

With [pix_record] I have systematically tried all codecs and colorspaces and I 
had no luck.

With [pix_writer], I did manage high quality frames with the correct colorspace 
which I then concatenated into a video (with ffmpeg). The drawback I have with 
[pix_writer] is the time it takes to write, which really complicates audio and 
video synching.

Thanks!!

dont know with [draw line(

but you can use [GEMglPolygonMode] with [GEMglLineWidth]
see attached patch
this solution works with [model] too

here, I can set it from 1 to 10 (but no more) pixels

Re: [PD] changing line width in Gem

[cyrille henry]

hello,

you can use the openGL command glLineWidth directlly with gem object 
[GEMglLineWidth]

but some (all?) primitive may reset this value. If so, you can send a [width 4< 
message to this primitive.

Cheers

Re: [PD] what happens when you send signals between 0..1 instead -1..1 to dac?

You might use your DAC to send control voltages for a modular synthesizer, for example. 


I have never tried this, but I guess it might be an edge case, and quite an 
interesting one.


(un)fortunately, most soundcard are DC filtered. This will not work, unless you 
have a very specific sound card.

This also mean than adding a hip~ 5 is not mandatory in most situation.

Re: [PD] get average luminance of the camera

[cyrille henry]

did you try [pix_resize 1 1] ?
cheers


Le 04/02/2020 à 14:17, enrike a écrit :

hi

Is it possible to get the average luminance of the camera input using GEM?

I am exploring pix_data but as far as I can see it only works with individual 
pixels. If I could average or reduce the color information from the camera to a 
single color, then I think I could just take the pix_data grey value of any 
pixel. But I am not sure this can be done. I am checking different pix_ objects 
but I dont see how I could get this to work. Any tips?


thanks

Re: [PD] shmem and bigger buffer size

I don't know why it fail on mac. You can try to split in smaller table, like

But you should also test it on linux first since it's your main target.

Re: [PD] shmem and bigger buffer size

[cyrille henry]

hello,

Do you have enough free memory on your computer?
I just test on y computer, I can reproduce this error as soon as I ask an 
allocation bigger than the available memory on my hardware.
(between 500 000 000 and 1 000 000 000 points)

Re: [PD] pd~ binary for max/msp

[cyrille henry]

most redefinition are a conflict between liboscia and m_pd.h
I would try to remove liboscia from your compilled path.

But I don't know if m_ph.h should be included :
it is removed for max from pd~ source thanks to a #define line 54 :
#ifdef PD
#include "m_pd.h"
#include "s_stuff.h"
static t_class *pd_tilde_class;
#define PDERROR pd_error(x,
#endif

but it's included from "binarymsg.c" (pd~.c, line 104)

I personally use pd on lot's of different computer, including computers that

having user-configurable shortcut can be nice, but having default shortcut that

Re: [PD] opening patch from pd message

[cyrille henry]

helo,

I don't understand why most people use send and receive object all the time 
exept when sending message to pd.

I think > [;
pd open $1.pd /path-topatch;(
 is very confusing.

having :
[open $1.pd /path-topatch;(
  |
[send pd]
is lot's more logic.

moreover, you can add a print and see what you are doing.
In this situation, you would notice that $1 is not convertet to cat.
(an error in pd log would also help to find the problem).


anyway, replace [cat< by [symbol cat< and it will work.

Dear list,

I want to open from a pd patch a pd patch withe the message:

[;

With simple naming of the patches such as numbers, works beautifully.
However if the name is a word, I cannot open them. What kind of command should 
I send to this message to make it work?

just to be clear, if I want to open cat.pd, a message [cat( will not make it 
happen.

Thanks for any hints!

Re: [PD] Raspberry Pi: Loading Samples RAM problem

[cyrille henry]

Le 11/11/2019 à 19:53, Jakob Laue a écrit :

Okay,
now I found some time to look at Giulios patch and I think I understood it :P 
(So many $'s in there :P)
So, what actually happens in that patch is that on [loadbang] we read 32768 
samples into an array using soundfiler.
Then when the file should be played, we do play the first 32768 samples using 
[tabplay~] and simultaneously load the rest of the file using [readsf~]. Then, 
when [tabplay~] is done playing the first bit of the sample, we send a [1( to 
[readsf~] to start playing the rest of the file.
I don't have any audio pops playing eight samples simultaneously, even using 
the cheap hdmi-to-cinch-converter as my audio interface (which caused more pops 
in comparison to the Scarlett USB interface while trying olivers patch). Also, 
I don't have to adjust Pd's audio settings. I can use the standard settings 
(44100, 64 blocksize, 25 msec) and I don't get audio pops, which is good.

But there is one thing that I realised: The wav-files are not played at 
original speed. They are all recorded in 122 bpm. When I play them with Giulois 
patch, the samples are played quite slowly, at around 111 bpm.


look like the sample are recorded at 48KHz and play at 44100.


In a later version of my sample player, I want to be able to change the 
bpm/tempo in which the samples are played, so I will need to have some 
mechanism for changing this. Using e.g. [phasor~] to play samples, this should 
work, but I don't know if it will be possible to do this using Giulios 
approach. In the help file of [tabplay~], it says that samples are played with 
no transposition, so maybe a transposition will not be possible to implement?! 
On the other hand, it says that [tabplay~] does not have the 
interpolation-artefacts that [tabread4~] has, which I would have, if I used a 
[phasor~] approach.


if you want to change the tempo, you need to somehow interpolate the samples...

All the best, Jakob

please also consider using even 2048 as buffersize for [ol_sfplay~]. AND
you might want to increase PD's audio delay with the "-audiobuf" startup
flag.

try "-audiobuf 120" or higher and work your way down from there.

i remember using this method on a PI2 with an 8 track wav-file and
really had to increase those values to get a smooth playback.

it worked alright in the end but then i had no video-traffic ...

in general, use a PI3 if possible

hello,


Le 22/09/2019   13:49, Ingo a  crit :

Hi everybody,

I have 3 questions about using the [pd~] object in an efficient way.
I'm trying to spread some heavy sample voices over multiple processor

cores.


1)
How can I read from common sample tables (or other parameter tables as
well) without having to load all sample (1 GB of samples) multiple times?
In the back of my head I think I heard about a "share memory" library
but couldn't find anything so far.

have a look at shmem, in deken.



2)
How can I assign a specific [pd~] process to a certain core?
Or does Pd automatically assign a new [pd~] process to another core?
It would obviously not improve anything if both patches were running
on the same cpu core .


This is what the OS is made for. In my experience, it just work.



3)
Is there a way that the [pd~] subprocess can receive the [send]
objects directly from the main process without having to resend each
individual send/receive object to the inlet of the sub process and
without having to build a receive object and then resend it by
prepending a header that can resend everything within the sub process?


No.
but this workaround can be nicely hidden in an abstraction.
you can create a [mysend] abstraction that is composed by a [send $1] and a
[list prepend $1] connected to a [send to_my_pd_tilde_object] etc...




I'm having a fairly large amount (185) of sends/receive objects and
tables (way more than 10,000 tables!).
Anything that might cut down the work and makes it more efficient to
run would be great!


you can search and replace all "send" to "mysend" on a pd patch using any
text editor.

cheers
C




Thanks a lot!
Ingo
