What's the deal with the ALSA mmap code?  Doesn't that use callbacks?



just an idea, what about using a signal (generated with sig~ or adc~) 
for checking if DSP is running, and send amplitude to another instance, 
or a daemon that would turn dsp on if signal isn't coming anymore, or 
kill and launch pd again if it doesn't respond to pings

I'm afraid callbacks would take a lot of CPU


(try compiling with and without FAKEBLOCKING and THREADSIGNAL

Re: [PD] can [bp~] be obtained with biquad coefficients?

f*ck, I'll be damned, now my patch that implements [bp~] with [fexpr~] 
seems to work, it's attached. Thanks!


thanks for the share, when I tried to implement filters with expr and 
biquad I haven't been able to get it working fully (some clics appeared 
when changing frequency)... Your implementation works very well in both 
cases, "chapeau bas"




> it's pretty easy to see that from the code you quoted

I can't really see it from the code itself. And, well, remember I 
mentioned about the biquad code?


{
t_sample output =  *in++ + fb1 * last + fb2 * prev;
if (PD_BIGORSMALL(output))
output = 0;
*out++ = ff1 * output + ff2 * last + ff3 * prev;
prev = last;
last = output;
}

Well, I made a silly confusion mistake and thought the first line was 
feedforward  (and then equivalent to the bp~). But still, it could be 
it for all I can tell. How can you actually see wether is feedback or not?


Anyway, the patch works and I can also make it on biquad, it's all 
attached.


> after all it's a resonating filter and therefore needs a feedback path.

I wouldn't know about that, but that's how you convinced me you knew 
what you were talking about :)


Thanks again

after all it's a resonating filter and therefore needs a feedback
path.
so it somehow has to take outgoing samples back in.


> So I feel pretty strong about getting this [fexpr~] right. Is
there anything I did not take into consideration?

yes, calculate coef1, coef2 and gain by using the formulas from
the code,
change the [fexpr~] to something like [ fexpr~ $x[0] + ($f2 *
$y[-1]) + ($f3 * $y[-2]) ],
(where $f2 and $f3 would be coef1 and coef2 resp.)
apply the gain factor afterwards,
and you are done.

Re: [PD] patch wanted: loop station

[patrice colet]

hello roman,

 there are several ways to sync audio loops, in most methods we try to 
read audio samples in a way that they are in sync by changing read speed 
or chunk size, or stretching it with fft, or by making slices with 
bonk~'s attack detection.


 The last methods allows to quantize sound by forcing a slice to be 
played on a timecode which is given by the size of the loop divided into 
sixteenthes, something like this, each slice could eventually be 
stretched to fit the timecode.

I don't know the loop station. Can you elaborate a bit how quantize and

Re: [PD] [PD-announce] Chocolate et Coffee

[patrice colet]

It's just a matter of using open-source tools for compiling this, I 
think using mingw for example on windows instead of VB would resolve 
inclusion in pd-extended, there is a makefile template in pd-extended 
sources.


This project looks really nice otherwise, this seem to not apply the 
same mess used in IEM widgets and others for including the GUI into a 
canvas, inspiring...

Hello,

 you can do this with internal message "menuclose" to a canvas

[;
my_patch_name menuclose(

Here is a method I've found yet to send internal messages through FUDI:

http://blog.tridek.com/post/29834155461/using-libpd-with-unity3d-on-mobile-devices-part-1

 In your patch create a [receive 3000] object with '3000' connected to an empty 
message box,
then you can fill the message box with the internal message and bang it. By 
this way it's possible
to create dynamically whatever you want in the patch, or simply close it.

Cool, make it yourse if you like, I still didn't finish this interface, and 
don't really know when it will be,
so what about putting the knowledge of several people on it?
There are some points I wanted to review,
 the main one is about using one canvas per bar because canvas is limited in 
size, I also would like to write an arranger interface for managing several 
tracks, and to be able to load/edit data from mrpeach/midifile... I should work

Re: [PD] datastructures midirecorder

[Patrice Colet]

Hello Rob,

 scalars can't be deleted actually without the GUI, but there are several 
tricks for doing something like it.

One is about using float indexes instead of using pointer order, and then set 
to -1 or another value that doesn't count
the scalars that have to be removed, and finally use a temporary structure for 
cleaning.
Another one is about using one scalar and an array for including your 
structure, so you can delete values inside element.
It's also possible to save, modify, and reload the structure with using a text 
file.

Just in case you are interested about using tcltk instead of datastructure for 
drawing your GUI (it still uses DS for sequencing)

I've shared a work in progress:

  pitch doesn't come from voice at all in these kinds of sounds, but from a

Re: [PD] openEXR in Gem

[Patrice Colet]

loading an exr image created with Blender failed with gem 0.93.git 374f713 and
image loading support: magick SGI jpeg tiff,
same image is loaded by cinelerra...

anyway I was interested about getting z-depth data, I didn't know if it was 
possible with pix objects

thank you

Re: [PD] Gridflow and fonts on Raspberry Pi

[Patrice Colet]

 I've confused a bit the first trick, renaming a proc could be necessary for 
procedures coded from pd messages, not the ones loaded from a tcl files. Also, 
introcing tcl classes could help for not having duplicated proc names.

 It would be nice to know if sys_gui is ok on Raspberry Pi in the case I'd use 
it on some project :D.

[sys_gui] can replace a large bunch of external objects (zexy, toxy, cyclone, 
moocow, ...), but a bit slower, and sometimes would require the need to use 
[makefilename %c] for curved braces, but in most cases tcl's [list ...] can do 
it. The new text object allows to store easily tcl code inside a patch or 
datastructure, I've found this usefull for storing image data... Including it 
into pd-core would make it very efficient for application designing, there 
still would be the need for [get_dir] in file processing though.

Re: [PD] Gridflow and fonts on Raspberry Pi

[Patrice Colet]

 I've collected some tricks since I'm using sys_gui, attached are the ones you 
might need to build and communicate with your interface through pd, if sys_gui 
is ok on raspberry, all the tcl and tk code is fully documented online...

Tested on Pd 0.45.0

Thank you for sharing this! Particulary the links at the end of the page, the 
shaders proposed at https://www.shadertoy.com
are easy to transpose for Gem, attached is an experiment with the fireball 
shader.

[PD] PMPD how to get constant distance between two masses

[Patrice Colet]

Hello,

 I'm trying to find a setting for linking two masses that have always constant 
distance, but couldn't find how to do it, the link is always resizing like a 
rubber instead of being solid like wood.
 I guessed that fixing K to an high amount would make a solid link, but this is 
breaking it instead.
The purpose is about applying forces to a cylinder represented by two masses 
and a link to make it rotating.

 Without opening pd I think it's something like range $1 $2
and that's what I'm doing when controlling DS from GOP,
it seems the best way to go..

 I'd like one day to understand how to implement DS into a GOP, it's a bit 
triky,
then on a single window it's possible to have the whole interface.

it's not really possible to do this in the context we're talking about because 
we don't know which scalar is modified when it's embedded into an array, a way 
would be about using y value, but in this case y is always = 0

Re: [PD] Data structures: no object for freeing pointers?

[Patrice Colet]

Yes with visibility setting we can access an element of an array only, so each 
state can be stored, retrieved, replaced at will by accessing an element of te 
array... The matter is how accessing an element, idealy it would be a [nbx] 
where max value is the number of array elements, or a scalar but I don't how 
it's possible to fix limits to [drawnumber]

Is it just possible to have background in black, and fonts (comments) in white 
without using [cnv] or [cyclone/comment]?

this setup is so usefull when working with lights.

It's still possible to put only one pointer and then arrays on it, then you can 
add or delete at the last array item, or it's possible to put an id at each 
array element and then remove the element id to delete, then it's possible to 
have undo's.

Re: [PD] GEM: texture on transparent sphere visible from opposite side

[Patrice Colet]

Hello,

 if the texture contains alpha channel by using a rgba image or by using 
pix_alpha, the visible parts of texture behind the sphere will become visible 
where front side is transparent, there is an example in gem tutorial but I 
don't remeber which one it is.

Every scalars have to be removed before modifying [struct] otherwise it crashes

too late, datastructure is really awsome for managing settings, the -v flag 
makes possible the coding of panels that is containing a lot of data...
 Is there a trick to copy data stored into a struct to an array element made 
with the same struct? I guess it should be possible to do it with textfile and 
some load/save messages, I'm actually doing it by using [get], [set] and 
[element], it a bit complicated... Would [sublist] simplify this task? How can 
we make list fields?

 It's hard to stay polite about this, for me it has never worked correctly,

Re: [PD] flip image in glsl

[Patrice Colet]

Hello Jack, 

 I didn't realized how using gemframebuffer is really an interesting approach, 
in fact there is no need to move textures with glsl because it's possible move 
objects rendered into the framebuffer, also the flipping problem isn't occuring 
anymore...
 The solution you are proposing here gives results I haven't expected, and 
might fit some other purposes that might come later,
since the texture processed by glsl (tex0) isn't anymore mapped with mixed 
textures (tex1 and tex2)...
 In all cases thank you for the contribution that gave me all the solutions I 
need in the project I'm working on.

Re: [PD] flip image in glsl

[Patrice Colet]

Hi Jack,

 the fragment code is now very short and much more elegant, certainly faster 
than using conditions, I guess this is due to [pix_info] that is computing 
dimensions of the resulting texture.
 This procedure seems to work for horizontal flipping then corrects strange 
behavior between pix_image and glsl,
but vertical flipping has no consequence.
 It's also possible to crop using the dimen parameter, but I believe there is a 
zoom parameter missing to do it entirely.
So I'm going to restart coding a fragment code from the basis you propose that 
would allow to crop both textures, because this looks fundamental for my 
possible use of this object, that is mainly about mixing two textures which 
coordinates could be modulated to fit a particular context, where textures 
would need to be placed accurately without having to modify it in an image 
editor, maybe you have an idea about how to do it simply?

[PD] flip image in glsl

[Patrice Colet]

Hello, 

 how is it possible to flip upside down an image in glsl example 05.multitexture

I tried to implement this in fragment program:

http://stackoverflow.com/questions/9857089/flip-upside-down-vertex-shader-gles

but it doesn't work. The only thing I can do is changing texture scale and 
position, but I couldn't do it with negative values
like it would be done in pix_coordinates.

In fact when I use pix_multiimage before pix_texture, the image gets flipped, I 
don't know why...

Re: [PD] Drawing a sine function dynamically in Gem

[Patrice Colet]

 Hello,

attached patch is inspired from code found in link you provide:

  for (int i = 0; i< width; i++){
px2 = width/8 + cos(radians(angle2))*(radius);
py2 = 75 + sin(radians(angle2))*(radius);
point(width/8+radius+i, py2);
angle2 -= frequency2;
  }

using Gem and recursion

Re: [PD] latest pd-extended-0.44 on win32

[Patrice Colet]

I think it's not worth to try because the problem is really coming from 
catalyst drivers,
 they just don't work good anymore, I've just found people encountering same 
problem with same graphic card on windows or RC2,
thank you.

[PD] [GEM] catalyst's multiscreen on ubuntu with amdcccle

[Patrice Colet]

 I'm making this thread just to prevent that ubuntu's multiscreen tools aren't 
good, and that there is a good command line that is not mentionned in ubuntu 
forums or manuals, I've found it in archlinux forums and it's called amdcccle, 
this command line should be available when proprietary drivers are installed.

Re: [PD] latest pd-extended-0.44 on win32

[Patrice Colet]

Ah, this might be because this thread wasn't mine, I forgot to mention it's 
happening in vista, where aero has been disabled the first day of use for using 
a classic desktop, as usual ;)...
 Gem has always been working on this computer, but I believe there has been 
some changes in system configuration that is really obscure for me, if only I 
had a tool that would tell me what's happening with graphic acceleration...
 The only point I could get with  OpenGL Extension Viewer is that it could not 
find driver version, and in display settings/Troubleshot tab it says that 
drivers couldn't allow acceleration, no more clue, reinstalling drivers doesn't 
change anything, the only option I have is about reinstalling windows, or even 
better, installing w7 or w8.
Thank you for taking care about this.

Re: [PD] latest pd-extended-0.44 on win32

[Patrice Colet]

I tried the win32 release archive proposed at iem.gem website, same thing is 
happening,

I'm wondering if this is coming from my drivers or hardware, so I've tried 
openGL extension viewer to have a clue,
attached is the result, couldn't try right now on another windows machine...

 Fortunately I also have a linux machine with a big graphic card
and there is no problem at all with Gem ^^...

[PD] latest pd-extended-0.44 on win32

[Patrice Colet]

Hello,

 I'm trying to make it working, yesterday there was a missing libjack.dll 
problem, it has been fixed by eighthave today,
now I'd like to have Gem working...

 [gemwin] is just not responding, no error message, with any patch, it does not 
answer after it's creation...
no idea how else I could report this.

[PD] [gem][arch] crash on loading image

[Patrice Colet]

Package was built yesterday

pd crashes at image loading

open: ./gem.conf: No such file or directory
Magick: Memory allocation failed `Cannot allocate memory' @ 
fatal/cache.c/AcquirePixelCacheNexus/270.

On pd-lork it simply doesn't load image, no crash, no error message.

1) Copy the pdvst folder to the directory that contains the 
   application (e.g. Cubase.exe) that you want to use PdVst with
   (e.g. c:\Program Files\Steinberg\Cubase VST\)

"

This is an extract from README.txt

you have to put pdvst folder with Live.exe wherever it is located.

this works:


C:\Program Files (x86)\Ableton\Live\Program\pdvst

C:\Program Files (x86)\Steinberg\Vstplugins\pdvst

just do this and eventually remove the other files than DLLs in 
VstPlugins\pdvst, or simply add pdvst folder to ableton vst directories

[PD] [GEM][pix_multiimage] error message

Hello,

 I'm using [pix_multiimage] into archlinux 64bit environment.

When opening the helpfile, I've got this error message into pd console:

GEM: Someone sent a bogus pointer to copy2Image

the object seems to work good thought, but is there a way to avoid getting this 
weird error message?

Re: [PD] Solution for deleting files via pd?

[Patrice Colet]

Hello,

in bash shell that would be something like 
[rm -rf /home/Sebastian/Desktop/folder(
|
[ggee/shell]

in ms-dos you can't specify a directory that is not relative to the patch (long 
story),
a simple way would be about making a batch script with this inside:

cd c:\Users\Sebastian\Desktop
rd %1

along with your patch

and then

[open yourBatchScript.bat folderToDelete(
|
[moonlib/popen]

or

[yourBatchScript.bat folderToDelete(
|
[motex/system]

Re: [PD] Jack support on Windows

[Patrice Colet]

> De: "Esteban Viveros"

ah if you put the vststuff.dll into vstplugin directory, and the pdvst folder 
that contains vststuff.pd patches vststuff.pdv files along with the vst host 
executable (it should be 'Program' folder for Ableton Live) it should be ok.

I've started some time ago to give a try into recompiling pdvst with a recent 
pd version, but no success yet.
It would be nice to have some patches to apply into pd-extended sources for 
having an actual pdvst version, but if I'm the only one interested into using 
this, it might not be worth the effort.

Re: [PD] Jack support on Windows

[Patrice Colet]

jackdmp has always worked with pd on windows because it has been using ASIO 
drivers, but with two channels only...

also I'm still using pdvst for playing with Ableton Live on windows, if not in 
debug mode, it's rather stable, and even if it's a 0.37 pd version, we can do a 
lot of thing with, like opening sockets and send MIDI or VST parameters, even 
running vocoder patches, etc ... In other words, no need for jackd, no need for 
maxmsp in Ableton Live...

Would jackd work with more than two in/out channels on windows?

Hello, I think I've found out where this problem comes from...
It's related with audio, asio particulary...portaudio is still a big problem 
here...

In some words, when asio doesn't work the mouse binding is out.

I'd be glad to put a bug report but I don't really know how to attribute this 
one,
it's both hardware (it might be a portaudio bug),
hardcoding (it might be how portaudio is implemented in pd), 
and interface (the tcl part shouldn't be involved when audio is messing up)...

Offset would be used for looping a part of the soundfile only, it's not simple 
indeed because we need to know the file length too, but's it's usefull for 
looping files writen in real time with [writesf~] for example, in this case the 
offset is used for reading the sound that comes after the end of the loop for 
mixing it with the begining of the loop, and then it can prevent to cut some 
sound's releases, or reverb.

using two [readsf~] is working so far so good for looping large soundfiles, 
with the offset option and a signal crossfading between them.

hello,

Are you really using cmd for compiling, or msys console?

On cmd you can select and copy with menu actions, cygwin uses cmd... 
In msys console it's truly like a unix terminal, Ctrl+Insert and Shift+Insert

Oh I just got it! we see the gemwin background on a rectangle surrounding the

so it's possible to fix it by setting gemwin color but it's not really

[PD] [text2d] background color

[Patrice Colet]

Hello,

 using GEM: ver: 0.93.3 compiled: Nov 10 2011

each [text2d] character has a black background, how can we change this?

Re: [PD] Circular scrolling in pd

[Patrice Colet]

hello,

what about converting cartesian to polar coordinates instead?

with something like

angle = atan(y/x)

you can even get the distance from the center with

R = Sqrt(x2 + y2)

that should be a lot easier

using 0.43.4-extended-20121211, ü.pd works from open menu, dnd, and recent 
files,
but when double-clicking on file icon, or from cmd, pd removes the umlaut and 
could not open.

I've tried it out with a file named ü.pd on vista, it is converted to u.pd:

same thing happens with cmd...

there is a class object suited for processing big lists called [gridflow], 
[list] isn't really suited to process large amount of data.

There are plenty of compressed formats so it implies a lot of different 
libraries,
and fortunately almost all is handled by gmerlin and then [readanysf~] external,
at the same time this external couldn't seek lossless formats like wav or 
flac...

I remember once a discussion about this topic where I proposed a solution using 
command lines
for the converting process, this is rather fast following the computer it's 
working on.

how do you read the header without binfile?

pd is not even able to read extended precision, that's why pd can't tell about 
aiff samplerate.

if you set manually array values, maybe [list-abs/list-len] is the answer...

something like this:

[.1 .3 .5 .3 .1(
|
[list]
|
[t a a]
||
|[list length]
||
|[;arrayx resize $1(
|
[list prepend 0]

[list trim]

[s arrayx]

It depends on how you read the table, if you are using [line~] it's easy, you 
just have to count how many time it's triggered,
but for some reasons I don't know, the sound quality will be bad with long 
soundfiles...

If you are using [phasor~] you can count ramp reset,
here is a track to do this:

Yes it does,

but anyway, my bad, I didn't read carefuly enough the help file that is saying 
sample resolution in *bytes*, not in *bits*.

maybe one day [soundfile_info] will read aiff files as well...

Hi Roman,

 I think that it's better when we can modify the behavior of an object by 
modifying a pd patch.
When everything is enclosed into an external, somehow it's private, and then 
it's not really pd anymore.
 More people are able to debug a pd patch, anyone could fix the problem without 
compiling anything.

 We should use C language only when we need it, in the example of [waveinfo] vs 
[soundfile_info], both aren't the good way for me,
we just need the [binfile] external for reading the header, and all the other 
stuff can be done into a pd patch.

Hi Jonathan, and thanks for answering,

most of the nice pdx stuff isn't in libdir format, like iem and Gem,
the last isn't so hard to fix, it's a just a single word to put in startup file,
but the first is full of helpfiles where many different objects from different 
libs couldn't be created,
some even crashes pd (win32 still, 20120720 version).

 Also the main problem isn't really about figuring out what's happening in 
patches,
but something that has been often debated in the list, conflictual objects,
same name but different behaviors, like [counter] for example, is this has been 
solved after all?

I use to remove all the stuff at startup and use this namespace/ stuff, or even 
better, the [declare] thingy in main patches,
then it's easier to figure out what's happening.

It would be cool to have this in help files, maybe it's not the best approach, 
but it's the best one I've found out.

semi-colon means that a message will be sent internaly to a [receive] object 
named with next argument,
this also can be a [table] object.

for sinesum message arg 1: Number of Points - arg 2: list of partial strengths

 I don't know anything about OSX, so I couldn't help with it. Maybe you should 
try first to understand what is a shell on OSX and how to use it.
Another solution would be about converting the downloaded soundfile to aiff 
with a command line tool like ffmpeg.

$ ffmpeg -i soundfile.flv soundfile.aif

then you can open it with [soundfiler]

> What do you mean with "an executable of wget"?

wget is a command line tool for downloading files, also there is something I 
didn't think about, you have to download first the html page,
and extract the link of the flv file with sed or awk, or python, or tcl, or 
manually, choose your weapons...

I give you an indice, if in the html sources the link is something like 
"streamUrl":"http://media.soundcloud.com/stream/123456abcdef?

the command line would be:

$ wget -O  soundfile.flv http://media.soundcloud.com/stream/123456abcdef

(sorry I've inverted output and link in precedent mail)

A last thing, be careful to not abuse with those command line tools, I suppose 
that soundcloud owners wouldn't appreciate if two many files are downloaded 
like this.

Re: [PD] Multiple Pd patchers on one computer?

[Patrice Colet]

 hello,

it should be possible with [hid] but it would require to make an interface for 
sending internal messages, and drawing several custom cursors.
Graphically I guess that the patcher would have to be made with another tool 
kit than tcltk by using a library like tkinter (already available),
or even better (I guess) with a gtk or a qt frontend external. Another solution 
would be about hacking Gem or gridflow for using multiple mouses, I don't know 
if it's possible.
