Dear Community,

I am trying to send OSC messages from my osc_send code to osc_receive, as shown in the image below. Even after installing mrpeach, I cannot create objects that use this external. What could be happening? I am using Pure Data 0.54.1 on Windows 10.

I have two patches on Pure Data as per the image below. As you can see, each patch opens in a different process. How do I send the values of one (which contains the send object) to the other, which contains the receive?

I want to send a variable number (e.g. int 1) from a lua script to Pure Data? How can I do this?
I'm trying [receive] object, but nothing happens.

This is my code in Lua. We also need pdlua to works.

local ginga = pd.Class:new():register("ginga")

function ginga:initialize(sel, atoms)
self.inlets = 1
self.outlets = 1
return true
end

@lucassilveira

Try this:

1. git clone https://github.com/agraef/pd-lua.git
2. cd pd-lua
3. git submodule update --init (checks if Lua are installed in same directory than pd-lua)
4. sudo make
5. sudo make install

After this, probably pd-lua will be installed on yout computer. Check /usr/local/lib/pd-externals

This is awesome. I made this little change and it works.
Thank you very much, guys. You're great.

@ddw_music
I made some changes in qjacktctl and now it works!
Bellow are my steps to achieve this:

1. Install pulseaudio-module-jack: aptitude install pulseaudio-module-jack
2. add to "/etc/pulse/default.pa" the following text: "load-module module-jack-sink
   load-module module-jack-source"
3. Put Pure Data and QjackCTL with this setup --> photo

Now, you can use Pure Data and other music and videos applications, like YouTube, Twitch or VCL.

@ddw_music
I'm using a built-in soundcard, on Linux Mint 20.04. QjackCTL it is also installed
Should I already be able to use the mic on Pure Data with the audio setting on JACK?

@ddw_music @seb-harmonik.ar

I used the specs from this link (https://askubuntu.com/questions/572120/how-to-use-jack-and-pulseaudio-alsa-at-the-same-time-on-the-same-audio-device ) and now I can hear sound from Pure Data and my browser at the same time.

However, for that, I had to leave the Pure Data audio media in the "jack", which prevents me from capturing the sound of my microphone using the following patch:

Any suggestions on how to resolve this?

Hello,

I have two very simple questions

1. Why when Pure Data, when running on Linux, does it not allow other audio and video applications to run?

2. Is there any way to resolve this?

Thanks!

@seb-harmonik.ar I want to run a Pd patch in a Lua script. So, I will try LuaPD. That was illuminating. I was trying to use pdlua for this

Thanks.

@seb-harmonik.ar Hi Seb

Can you provide me some example in how to run a pure data patch inside a Lua script?
Prints and pictures are appreciated

@seb-harmonik.ar It look likes that I do not install pdlua correctly. I will try reinstall and run the code again.
Thanks, Seb! Stay tuned on this post for news.

@seb-harmonik.arI installed the pdlua library in Lua's package.path directory and the following error appeared:

./pd.lua:22: attempt to index a nil value (global 'pd')
stack traceback:
./pd.lua:22: in main chunk
[C]: in function 'require'
test.lua:1: in main chunk
[C]: in ?

I'm getting inspiration from some codes present here: https://love2d.org/forums/viewtopic.php?t=90014

@seb-harmonik.ar I remove the require, but errors continue. I do not know what to do.

Hello,

I have this code in lua (teste.lua) that allows to create pure data patches in this language. However, when running it, the following error appears: "module 'pdlua' not found", even though I have the library installed.

Does anyone know the reason for the error?

@oid It look likes luajack package is broken =(

@oid Thanks for the answer.
I will run some tests with this tool and let you know the results.

I'm creating a Lua script capable of capturing the sound of my microphone in real time. Can I use the Ofelia library to send the sounds captured in Pure Data to the Lua script?

@alexandros @seb-harmonik.ar Seb, you are right. I want to 'use' a Pd patch inside Lua.
For example, using the audio from my microphone (which is captured in Pure Data) in an application made in Lua.

I discovered this library (https://love2d.org/forums/viewtopic.php?t=90014&sid=055636f859e6b8ab0e470c4aaeb8c605) but it looks like it's only useful for the LOVE game engine.

Hey guys

I know that it is possible to use Lua scripts in Pure Data using pd-lua. And the opposite, is it possible?
