Little patch below, seems creating the problem, (but as always, maybe coming

[PD] Old feature : pd extended re-opening patch from within after crash Mac OS

[Jean-Marie Adrien]

Hi list

I am running an historical patch on Mac which combines the old school features 
of GEM under pd extended (32 bits) and a 64 bits more recent version of PD, 
dispatching the overall tasks on several cores.

When the Mac shutdowns by accident, because of power drop for instance, without 
the patches properly quitting, then, when I relaunch pd extended, it 
automatically re-opens the former patch which was running before crash : 
feature coming from within pd extended probably because this is not the case 
with the 64 bits version running at the same time.

Any one got a hint to cancel this automatic reopening of crashed patch from 
within pd extended when you relaunch the pd app from fresh ?

Thanks
JM

[PD] Basic send historical issue 32 bits / 64 bits

[Jean-Marie Adrien]

Hello list

Upgrading some old historical patches I wrote twenty five years ago (yeah, some 
of you were not born!) with having two instances of PD extended 32 bits 
communicating with each other, via
{netsend} and {netreceive} objects.

The need was to send from one instance two the other a message in the classical 
form of a message with (label_name float float float …> structure
It was done the following way in that time

{pack s f f f f f f}   ->   {l2s}->   (send 
$1>   -> {netsend}

Make a package, 
convert  in symbol,
send to nestend via (send $1> argument of netsend



Then in the other instance
{netreceive}  ->  {route  label1 label2 …}. 
   ->   {send label1}  {send label2}   etc

Net receive output directly connected to 
route object with as argument any possible label 
Delivering as many send labelx objects further to the second pd instance


Route accepted this format receiving from pd32 bits. 
Doesn’t work anymore. 
I’ve red somewhere that the type of objects in pd was historically a bit 
awkward in the view of Miller concerning lists and messages.
Red again the old manuals, didn’t get it really better than 25 years ago, saw 
that something has changed in the past concerning the send object :)

Could some one tell me what is the correct way to solve this basic and easy 
issue today, with a perfect style ?
Need to have it work quickly :)

See patch  below !
Thanking you
JM

[PD] OsX : pd 53.0 or pd 52.2 now :)

[Jean-Marie Adrien]

Hello list
I have an important production in January, and have to do it on OsX Monterey M1.

The thing is that I have to upgrade old complicated  historical things in 32 
bits (yes !) finally to 64 bits at this occasion and, 
I began last month to have a feel about this task,   by running pd 52.2 with 
rosetta on Monterey a couple of hours, and it seemed feasible.

Went back to this job today, and pd disappeared from the apple mini Mac 
(because of automartic upgrade of Monterey !) and all what has to be found on 
the net now, thanks to everyone and particularly Miller, is the brand new pd 
53.0 :

Basic questions concerning this new version

1- no need of rosetta (on Monterey M1) I guess ?
2 - are most common libraries (gem) available in this format or is it better to 
find somewhere a pd 52.2 and go with rosetta and old 64 bits libraries until 
everything is « available » 

Thanks to all :)
JM

Re: [PD] who still needs Pd 32 bits for macOS and why?

[Jean-Marie Adrien]

Hi
Still using 32 bits pd, (and also 64 bits) : 32 bits are necessary not for PD 
itself, but for drivers of external hardware working with pd, because 
applications based on pd integrate many hardware pieces, some of them old, and 
obtaining a stabilized and cheap integrated hardware set is some work. 
One day ill have to make the jump, though, obviously ... and upgrade hardware.
Nice to read that now almost everything is available in 64 bits however on the 
pd side, and thanks for the wrk !
What about big sur ?

[PD] Good filtering package

[Jean-Marie Adrien]

Hello List
Just to know : is there somewhere a good package / object for sound filtering 
with a sort of graphical interface showing the transfer function a bit like 
what is available in the Logic pro channel EQ, (a bunch of filters with 
frequency center, Q and dB sort of and resulting transfer function against 
freq) ?
Thanking !

Hi
got some problems myself from time to time with GUI elements poorly updating 
when pd has a very big CPU load, zb several instances of pd running at 60

quit and relaunch

Re: [PD] Pd & massively multi-channel wi-fi speakers

[Jean-Marie Adrien]

hi
as far as i know, two major problems
- wireless speakers to be found for sale in the industry are based on the 
stereophonic paradigm, music coming out of two holes and that’s it
- wireless technology introduces some latency, which is somehow contradictory 
with the  pd real time approach, even more since the industry runs now after 
the personal assistant segment, to generate more profit, and this introduces 
though even more latency, which is in itself not a problem if you playback dead 
sounds like in the last millenium.

there must be some ways to turn around these problems though, like radios 
indeed :), but these ways around have to be considered in balance with 
installing simple cables, and this even more if sound sources are not mobile in 
space.

i am however always curious to learn about the subject

yes i checked and apple said that mojave would be the VERY LAST Os running 32

Nxt Os will come in fall 2019, means we have ONE YEAR either to throw away our

[Jean-Marie Adrien]

Hello
Trying to reopen an old patch with pd-extended, and erased the corresponding 
pd-preferences by mistake !

Did everything again in the path prefs at startup, and one function is still 
not found :
it is mtx_./, and mix*, arithmetic multiplications and divisions of matrices, 
belonging inside a very useful fir_mean_n filter.

Actually both iemmatrix libraries and iem_matrix are in the paths
Does anyone knows where this objects are ? guess an iem library ??

(actually this object can open it with pd extended 42-5 but not with pd 
extended 43-4, the latter being the version i currently used to open it, so i 
am trying to unscrew the prefs and any hint about the source library is worthy 
in this process…).

Tks !

Re: [PD] metro 1000 is 3 times faster than a second

[Jean-Marie Adrien]

mabye you could set dsp on (and off again if needed) this will synchronize pd 
in a more reasonable way
… and keep an eye permanently on this aspect if time measurement is critical 
for ur patch
(high load might blow pd out, means 1 second is lasting three seconds or so, in 
this latter case there is little to do besides optimizing the patch)

Re: [PD] videoPYLON C++ update needed

[Jean-Marie Adrien]

by the way i use extensively vintage PAL cameras with GEM on mac since 15 
years,  and i would love some update allowing for faster cameras and higher 
definition cameras because i fear things will simply not work anymore one of 
these days… means it won’t be possible to find standard definition cameras for 
instance, cameras which long ago disappeared from macs.

i react to the donation issue : i would be ready to give some personal money 
for quicktime compatibility, maybe some other pd users would also do so … 
because this is in my case personal money and not institutional money, maybe 
there could be a way to set up something like a kickstarter project with many 
contributors (backers) all of this resulting in a decent amount … ?
just thinking ...

[PD] big bounce writesf~

[Jean-Marie Adrien]

Hi Everyone
I am making a stereo bounce of a long 8 channels real time performance and, 
when listening to the result, some sounds seem to be missing…
Basically, while performing, the patch redirects sounds channels to a stereo 
writesf~ using throw~ & catch~, all of this being poured in a .wav file on disk.
Mysteriously for instance, the freeverb~ output is missing.
I could try to rearrange the throws~ & catches~ but before that, any one has a 
hint about what happens ?
Thanks

[PD] Displaying an image with pix_image / pixellisation

[Jean-Marie Adrien]

Hello everyone

I want to display an image on a full HD screen, but adjusted in display size in 
the screen frame.
When i display the image full scale (closes to real size, means big) the 
definition is superb, consistent with the image def (i do this with texture -> 
rectangle)
If i reduce the size of the displayed image in the frame (either by reducing 
the size of the rectangle, or by translating in Z, or by scaling 0.5) the image 
is then getting very much pixellized (far under computer screen def)
Is there a way to overcome this ?

I mean if i visualize a pict with any PC pict visualizer, definition will be 
optimized even if i display a high def pic in small display size : 
can we do this in PD ?

Thanks

yes, and i am very thankful because i use pmpd every day (OsX) to generate 
beautiful control shapes (i.e. natural gesture simulation)

Re: [PD] modal synthesis examples?

[Jean-Marie Adrien]

would be great if it would be in pd abstractions !
everything is in the paper though, you are right, and the method is incredibly 
powerful, so the project was in that time to control it with gestures data 
bases and artificial intelligence and so on, all of this being existing now, 
not speaking about multi channel sound diffusion etc.
I was disappointed when, after having developed the method at IRCAM, i 
discovered (and had to pay for it though) some ten years ago the actual modalys 
thing that was kind of retro engineered after i left IRCAM, from the big C++ 
initial software with was developed between 1984 and 89.

The math is not so complex, it is just a matrix equation incremented step by 
step, and very straightforward and intuitive discontinuities in time domain 
which correspond to straightforward updates of the matrix, resulting for 
instance from contact between objects and other intuitive events.
If you simplify the maths, it will probably become more complex i’d say, and 
you will probably hear it, because time domain sound synthesis is quite 
sensitive.

On the same line, one advantage of modal synthesis is that you can achieve 
impossible physical excitations on imaginary structures, and interpolate 
between all this, having transient sounds and articulations, but even with the 
full math though, you could hear in that case that you were sort of tearing the 
equations, which corresponds to the fact that there is no existing physical 
gesture which you could refer to when exploring impossible configurations.
Math simplification is what happened probably when the available pd modalys 
software was achieved : i was disappointed by this tool and rarely use it.
Another application has been developed by Apple in Logic with the "sculpture » 
plugin : it is very much main stream, they probably make money with it and Im 
still poor. Bref.

I’d love the true vintage thing on pd now : it is just implementing a matrix 
equation with updates conditions.
The point is that, thirty years later, i do not understand anymore a single 
line in C++, although I’ve written many thousands of lines. 
Hmm. I dont believe it myself, how is this even possible ?  But i remember very 
well the principles. Id be happy to help if i can anyway.

Re: [PD] modal synthesis examples?

[Jean-Marie Adrien]

Hello
There is at IRCAM a pd implementation of modal synthesis, called modalys.
Modal synthesis is different from oscillators or karplus strong, in that it 
takes account for frequencies AND space data of vibrating structures (modal 
shapes), making it though possible to synthesize transient sounds and 
articulations in time domain which are difficult if not impossible to modelize 
in frequency domain. modalys is a pd library, works in real time and is a 
(very) simplified version of a lisp / C++ software which was developed in 80s, 
the latter making sounds more real than natural sounds. For more info, see 
JM ADRIEN (1989) The missing link : Modal Synthesis, in "The Representations of 
Sound", G.de Poli, A.Piccially and C.Roads editors. The MIT Press, Cambridge, 
Mass.

[PD] Finding a nearly full quadrilateral in a video frame

[Jean-Marie Adrien]

(sorry for posting again / mail address & account micmac, hope i did not miss 
any answer !)

Hello list
I have to find for an installation the four corners of a bed (a rectangle) seen 
from above against the background (the floor), and this bed might slide a bit, 
so from time to time update the coordinates of the four corners. A person might 
be on the bed or close to it. So the general problem is

find the coordinates x,y in the video frame (GEM) of a nearly 
perfect quadrilateral with a rather simple overall visual configuration  

Apparently, haarcascade techniques  which work fantastically for face / hands 
(A.Villeret) seem inappropriate because the rectangle or quadrilateral is a too 
simple shape : 
anyone has a hint ? any object around ? blob ? lines - boundaries ??

Thanks a lot !
