[PD] defer or deferlow or 'delay 0' in puredata?

[Ali Momeni]

hello all,

i need to resize an array used for audio while audio is playing, and this
is causing a big hickup (working on an embeded linux system).

in max land, i'd next try to do a 'deferlow' or some such, to defer the
message to a lower priority queue, hoping to solve the audio hickup.

how do you, or can you, do a deferlow or 'defer' or 'delay 0 ' or 'delay
this message to a low priority queue' or 'do this message in between audio
vectors?

thanks,
ali

Re: [PD] why not Purr Data?

[Ali Momeni]

thanks everyone, this is really helpful.

in light of your experiences, it seems like the best of all worlds might be
to use a modern computer/os with Purr Data for editing, make sure to stick
with vanilla only objects, and use vanilla for deploying.

anyone see any potential pitfalls there?

[PD] why not Purr Data?

[Ali Momeni]

Hello all,

I've been playing around with the latest Purr Data from:
https://agraef.github.io/purr-data/

and, well, I love it.  The entire experience of working with Pd is much
more pleasant.

I'm compelled to ask the group, especially the Pd Vanilla users among us,
the following simple question:

What reason is there NOT to use Purr Data?

Am I missing something?
Subtle disadvantages?
Missing functionality?
Reliability?
Performance?


Thanks,

Hello all,
Sorry for the delay, I was traveling and didn't have access to multiple

I had a chance to send the 0.48-1 build from Dan and it seems to have fixed
the jumping window problem!

Thank you and well done Dan!

Re: [PD] trouble with pd-0.48-0 and multiple screens

[Ali Momeni]

I my experience, the problem seems to occur if multiple screens are not
aligned horizontally.
If i arrange my 2 external monitors to extend the right side of my screen
to the right, i seem to have no trouble.
If i arrange them to have a screen extending the top of my laptop screen,
and another extending the right side, many jumping window problems.

[PD] using tabwrite~ for a circular buffer?

[Ali Momeni]

hello all,
is there a way to use tabwrite~ for a circular buffer?

in other words, is there a way to make tabwrite~ go around and start
recording in the beginning of the table, once it has reached the end?

i have done some searching and found this thread:
https://forum.pdpatchrepo.info/topic/8260/creating-a-live-input-circular-buffer-using-array

but there seem to be no resolution;  i realize that you can do this with a
different method of writing into tables that's driven by events, but i'd
like to do it with tabwrite~ and all signals.

thanks!

Re: [PD] trouble with pd-0.48-0 and multiple screens

[Ali Momeni]

I'm using MacOS 10.12.6

I'm impressed that so many pd versions and platforms have this issue.
It's a very difficult problem to deal with; Pd is essentially unusable with
multiple screens.

Does anyone have an intuition of how Pd manages to break the OS's window
management?
Anything to look into?

thanks.

[PD] trouble with pd-0.48-0 and multiple screens

[Ali Momeni]

Hello all,

is anyone else using 0.48 with multiple screens and multiple desktops?

i'm having a very difficult time using pd because the windows for
subpatches that I open keep jumping to random places mostly off the screen
on the "main" screen; it doesn't seem to happen when i click on things
even; total nightmare!

has anyone seen this strange jumping window behavior and is anyone aware of
a workaround?

Re: [PD] going from signals to events?

Agreed on all fronts.

The reason i'm keen on having a master clock that's audio driven is because
i also want to sync my step sequencer to looping audio buffers, playback
with a phasor~

I see that this could also be done with with metro (i.e. trigger playback
of the audio file)

Re: [PD] going from signals to events?

[Ali Momeni]

Thanks everyone, super helpful.

@peter:  it seems to me that `max~` and `min~` take signals in and put
signals out.  How would you use them to go from signal to event?

@liam:  yes!  `threshold~` is what i was looking for; i'm always up for
doing the extra work to stick with vanilla.

@claude: deep.  i'll look at the expr~ example, very helpful reference.

hello friends,

what are your favorite objects for going from signals to events?

specifically, i'd like to make a sample accurate / audio-driven sequencer.

Any ideas?

Thanks for clarifying Alexandre.

I would like a pure Vanilla solution because I need to run my application

I'll make do with the 'text' object for now unless there is an obvious

Re: [PD] your favorite key:value data structure?

[Ali Momeni]

Thanks everyone, this is all very helpful.

"text":
Great.  Can use search, works fine.

"coll":
My understanding is that 'coll' is NOT a part of vanilla, but rather a part
of 'cyclone', not maintained by Miller.  Since I'm looking for a pure
Vanilla solution, this is not a good choice.  right?

"struct":
I understand that you can invent complex data structures with this object.
My 2 questions are:
-is there an easy/out-of-the-vanilla-box way to go from text files to
struct?
-i don't see how struct implements the "key" of my desired key/value pair.
 is that the name of the pd subpatch that has the struct object in it?

Thanks also for the hot PuRestJson tip, will look into that for future
adventures.

Hello Jonathan,

Thanks for your reply.
I'm not quite sure what you mean.

What pd-vanilla object do you use to implement "Variable number of keys of
arbitrarily typed values" or "set number of keys with set value types"?

I should add that I'm interested ultimately in a data structure that I can
populate from text files, read by PD.

[PD] your favorite key:value data structure?

[Ali Momeni]

Hello all,

I'm looking for something analogous to the Max "coll" object, or a python
dictionary, or anything with key value pairs.

I'm aware of the 'cyclone' and its 'coll' object.

i'm wondering if there is a pd-vanilla friendly alternative to this 3rd
party external.

any hints?

thanks in advance,

ali

Re: [PD] libpd, Android, and Unity3D - any recent data?

[Ali Momeni]

Hello all, hello scott,

My apologies for being silent on this thread, I missed the original message.

I asked a similar question a few months back on this list and got a few
pointers, and then spent a few days digging really deep into it.

The Kalimba  and UnityLibpd solutions that you've found are ok.  UnityLibpd
(https://github.com/Wilsonwaterfish/UnityLibpd) and LibPd4Unity (
https://github.com/patricksebastien/libpd4unity) definitely worked better
for me than Kalimba which seemed to be less uptodate.  The other solution
that hasn't been mentioned but definitely merits attention is
https://enzienaudio.com/, formerly known as heavytools.In my view, this
is by far the most powerful cross compilation/integration tool out there
for getting Puredata embedded into other environments.  Specifically, you
upload a pd patch to their site, and it generates for you a number of very
interesting things, including native Unity libraries and code for running
your pd patch (including builds for mobile), as well as embeddable
javascript and a bunch of other stuff.  IMHO, pretty amazing work.

If you decide to go down the libpd4unity route, i put together a working
starter-project in unity that may be useful for you to get going:
https://github.com/cmuartfab/libpd4unity-starter


Looking forward to hearing more about what you're doing with unity and pd;
there are at least 7 or 8 of us in the world that care about this
combination :)

Re: [PD] smoothing numbers: something like Max's "slide" object?

[Ali Momeni]

Thanks daniel; i'm aware of this technique.
Im specifically looking for a smoothing method that allows variable amounts
of smoothing, and also implements a way to have increasing values be
smoothed differently than decreasing values.

Any thoughts on that?

Can someone point me to an existing abstraction/external that behaves

Re: [PD] libpd for Unity still alive?

[Ali Momeni]

Here is another question for the libpd4unity crew:

What is the right approach for mixing audio generated by PD, with audio
generated by Unity?
It seems that my "AudioListener" component attached to my "LibPd" game
object is preventing any other Unity AudioSources to play sound.

Any experience with this?

Thank you,

Ali

This is great to know; i will try that.
To answer your question, I do not have this latency issue in the editor.
Even more importantly, I don't have this issue when i build the same Pd
patch for android, using the libpd4unity approach, as i've done here:
https://github.com/cmuartfab/libpd4unity-starter

Hello all,
This is wonderful, thank you for contributing to this thread. Glad to see
that Unity + PureData is active:

@wing: I also put together a unity+pd integration example; it has a
bouncing ball withs sonification done in Pd; works on Android!
https://github.com/cmuartfab/libpd4unity-starter  I will take a look at
your work also, thank you for sharing that.

@scott: I also tried Kalimba, but i have massive latency on Android, on the
order of 300-500ms.  Did you have this experience?

@scott+@wing: can you give me an example or two of when you may need
multiple instances of LibPd in one's unity project? Couldnt you just make a
more complex Pd patch that has all the things you want happening in it?

My problem is with LibPdFilterRead.cs as it doesn't compile because of this
error:


*Code:*

public void OnAudioFilterRead (float[] data, int channels)
{
if(dataPtr == IntPtr.Zero)
{
dataHandle = GCHandle.Alloc(data,GCHandleType.Pinned);
dataPtr = dataHandle.AddrOfPinnedObject();
}

if (islibpdready) {
*LibPD.Process(numberOfTicks, dataPtr, dataPtr);   //THIS
is the line that throws an error*
}
}


*Error:*

I have the Magicolo example working in Unity 5.4.1f1, but the notion of
contains/mixers/sequencers seems too high-level for me; i'm looking for
something much more simple; a pd patch making sound in unity, and audio and
control input and output to and from the patch.  Can Kalimba do that for
you?

[PD] libpd for Unity still alive?

[Ali Momeni]

Hello all,

I'd like to play with libpd within Unity.  I've come across several project
that attempt this:

https://github.com/patricksebastien/libpd4unity
https://github.com/Magicolo/uPD
https://github.com/hagish/kalimba

but it seems like they are all old and not maintained; it also seems that
they haven't been tested with Unity 5.  Does anyone have any recent
experience with pd and unity?

Regards,

Re: [PD] Granular Synthesis External

[Ali Momeni]

Excellent question Cyrille.
I happen to agree with you; most granular synth sounds terrible to me also,
especially if it's real-time and hasn't gone thru fancy post-processing.

That said, i think the new external that has set this thread in motion is a
very good example of what parameters should be available to the user.

Re: [PD] Granular Synthesis External

Thank you Oscar for this contribution; it's a very helpful external.

I'm curious what else is out there to compare.  Is anyone following this
thread aware of other granular synthesis externals out there for PD that
are worth considering?

Re: [PD] Granular Synthesis External

[Ali Momeni]

Hello all,

I'm successfully using the external under OS X 10.11.5, with pd-extended
.43-4, using José's external.

I'm not able to find the answer to this in the tutorials: how do you set
the start position of the grains in a table?

[PD] sox fifo readsf~ not working

[Ali Momeni via Pd-list]

hello all,
i'm trying to catch some internet radio streams with sox and pass the audio
to pd to process it.

so i first make a fifo buffer:

*mkfifo ~/tempaudio*

then i run a sox command that catches an mp3 stream, and writes it to a
wave stream in the fifo buffer made above:

*sox -v .9 -t mp3 http://icy-e-04.sharp-stream.com:80/lincsfmrutland.mp3
http://icy-e-04.sharp-stream.com/lincsfmrutland.mp3 -t wav -input-buffer
8 -r 22050 -c 1 ~/tempaudio*

these commands run with no errors; i'm executing both as sudo.

then i open pd and try to run readsf~ with the fifo file above as the input.
when i send the open message to readsf~, i have no error:

* open ~/tempaudio*

then i send the start message message and i get an error:

*dsp:/home/pi/tempaudio: unknown or bad header format*

i've tried some other params in the sox write command but i get the bad
header error no matter what i do.

any thoughts?

thanks,

ali

[PD] Fwd: Fwd: sox fifo readsf~ not working

[Ali Momeni via Pd-list]

Hello,
Thanks @cyrille, found the answer to my arguments for open question in the
help file as you said.

@ben: first, hi!
second, i'm a ware of a number of 3rd party externals for pd that are
supposed to do streaming in, like mp3amp~ and ogg~ and readanysf~
but none of them are really working in pd-vanilla on rpi for me.  some
crash right away, and others never get a stream.

sox on the other hand is working beautifully and is rather robust, and the
fifo solution for getting audio into pd seems critical/awesome enough that
i'm keen on figuring it out.  i see that sox is getting the stream (i have
tested it by sending it to pifm and its there), but i'm just hung up on the
header format of the file.  pd doesn't like it.

i'm wondering if there are details in 'mkfifa' that make it better for pd
reading
i'll report back if i discover something...

 Hello,

 not the answer, but you can open stream inside PD with readanysf~ if you
 can accept this dependency http://aug.ment.org/readanysf/
 else y use this command to pipe a raw flux to sox  stream, maybe you can
 adapt :

 sox -t raw --ignore-length -r 44100 -e signed-integer -b 16 -c 2
 bridge.fifo -t ogg -C 5 - | oggfwd labomedia.org 8000 rclabo01
 /streamtest.ogg

 or I modified .asoundrc so as to allow a non jack software (sox/aplay) to
 get into jackd as an input :

 cat ~/.asoundrc

 pcm.rawjack {
 type jack
 playback_ports {
 0 system:playback_1
 1 system:playback_2
 }
capture_ports {
0 system:capture_1
1 system:capture_2
}
 }

 pcm.jack {
 type plug
 slave { pcm rawjack }
 hint {
  description JACK Audio Connection Kit
 }
 }

 and then :

 aplay -i anyaudiofile-flux -v -D rawjack

 hopes it can help

 Hello Cyrille,

 Thanks for the help
 still have the same problem:



 *dsp:/home/pi/tempaudio: unknown or bad header format*

 try providing the header to pd
 open ~/tempaudio 0 0 1 2 b



 no error when i send this open message,
 but when i start, i still get

 unknown or bad header format

 where do you get those numbers, 0 0 1 2 b ?
