Thanks for those links Monetus. I'm pretty close with my existing setup and will first try to work with that when I have some more time. Some of the output from the samples/cpp/pdtest appears to be as expected.

However, from main.cpp

    cout << endl << "BEGIN Patch Test" << endl;
    
    // open patch
    Patch patch = pd.openPatch("pd/test.pd", ".");
    cout << patch << endl;
    
    // close patch
    pd.closePatch(patch);
    cout << patch << endl;
    
    // open patch again
    patch = pd.openPatch(patch);
    cout << patch << endl;
    
    // process any received messages
    //
    // in a normal case (not a test like this), you would call this in
    // your application main loop
    pd.processFloat(1, inbuf, outbuf);
    pd.receiveMessages();
    
    cout << "FINISH Patch Test" << endl;

the response

BEGIN Patch Test

seems right but no patch was opened and if I already opened that patch before running the executable, none of the print messages (called later in the code) showed up in the console of pd. I'll focus on this and try to repost to the forum when I have a better idea of what is going on.

Hi! I am running Pd-0.47-1-64bit on Mac OS 10.11.6 and libpd 0.9.2. I am trying to work with the samples/cpp/pdtest. Here's the github repo. I currently have an app that takes video and spits out a 2D array of color values for regions of interest to file. I have a pd patch that then loads those into a table and plays the corresponding pitch. I need the two (patch, c++ app) to coordinate the IPC.

I compiled the cpp code in the samples directory however, when running pdtest executable there is no patch opened. Is this by design? I was not able to find a pd-vanilla to build from source so took the most recent (pd-0.47-1-64bit.mac.tar.gz). Does libpd need to have the pd built after libpd? If so, can anyone please point me to a src file?

Here is a truncated output from running the compiled pdtest. Could someone tell me if this is what is expected?

Thank you for your help.

HI!

Quick version:

My folder structure:
/mother-patch.pd ( main pure data patch first loaded and running... )
/patches/1/main.pd
/patches/2/main.pd
/patches/3/main.pd
...

How i could open /patches/1/main.pd triggered by some action in the mother-patch.pd?
How i could close /patches/1/main.pd triggered by some action in the mother-patch.pd?

Long read

I'm attempting to clone the Critter and Guitari organelle ( link ).
This instrument is basically a computer running libpd and running very cool pure data patches
You can read more about my project here ( link )

I have a mother pure data patch that it's first loaded when the device is on, this patch is doing some [send] and [receive] operations related to the knobs/keyboard/volume/led and it should be also managing the loading ( opening and closing ) of the child pure data patches ( mentioned above ). This child patches are receiving the actions from the mother patch.

If I open the mother patch and the child patches manually, everything works fine. But now I need to OPEN this CHILD PURE DATA patches with a object within the mother patch.

I've been testing [open] , for opening the main.pd of the child patches but it does not work.
I've been testing [pd] , for opening the main.pd of the child patches but it does not work.
I wouldn't like to modify the original organelle patches.
I wouldn't like to end up loading all the patches using [pd ...] and inserting a [switch] object inside every main.pd file in the patches in order to enable only the dsp of the desired patch.

It would be perfect If i could have a folder with all the patches and load them within the mother patch with some kind of object. And I would also want to be able to CLOSE the pure data patch and open another ( changing patches... )

Every little and big help woul be MUCH APRECIATED!

THANKS!!!!!!!

hi there,

I've got pd running fine for sounds but I'ld like Gem (for a reactable); but I've got this error at pd startup :
