I am writing a c-external which should write different Values to a 2x2x3 Matrix. The Matrix should be stored in a .jxf file and should be able to read back in a normal Jitter Patch for further processing.

 if (x->brightnessmatrix == NULL) {
     jit_matrix_info_default(&info);
     info.planecount = 1;
     info.dimcount = 3;
     info.dim[0] = x->cols; //set to 2
     info.dim[1] = x->rows; //set to 2
     info.dim[2] = x->frames; //set to 3
     info.type = _jit_sym_float64; //_jit_sym_float32
     x->brightnessmatrix = jit_object_new(_jit_sym_jit_matrix, &info);
 }

I am setting different brightnes Values inside a loop for each cell and every Frame:

for (i = 0; i < x->nrOfCells; i++) {
    yCellPos = i / x->cols; 
    xCellPos = i % x->cols; 
    
    brightness = 25. * i;
    post("i: %ld", i);
    post("x->currentframe: %ld", x->currentframe); //is set outside the loop
    post("brightness: %f", brightness);

   
    brightnessp = brightness_bp  //pointer to matrix
        + xCellPos * sizeof(float) //xCellPos times 
        + yCellPos * sizeof(float) * (&brightness_minfo)->dim[0]
        + x->currentframe * sizeof(float) * (&brightness_minfo)->dim[0] * (&brightness_minfo)->dim[1];
    *brightnessp = brightness;

}

When i Run the code above i get following output in max console:

    err = JIT_ERR_NONE;

When i use following Patch to load the brightness.jxf back to Max Application i get only 0. values in the matrix: 

ReadingMatrix.maxpat

So is there another way to read the values in a 2x2x3 Matrix?

Or have i made a mistake while storing the values into the Matrix in my external?

I'm working on writing an external that sends max audio signal over the internet, via UDP, directly from Max/MSP. I'm using Libuv for asynchronous I/O in an effort to reduce latency.

My question is this: how can I copy the entire signal vector at once, into a buffer that I can then send. I've reviewed the original Olaf Matthes netsend~ code and then the same netsend~ as updated by Remu and Oliver Guillerminet, and they use the old style performance methods where t_signal **sp is passed to the method and then the signal vector can be grabbed from sp->s_vec.

The new dsp64 process uses double, I know. And I _believe_ that it is a double pointer to another pointer that is an array of the samples, but without access to the code that passes variables into that routine, I'm fumbling around, not really knowing what's going on "under the hood". Does anybody have any insight into how to do this?

At this point, my best guess would be to hop into the perform64 method, and do something to the effect of:

memcpy(my_vector, inL , sizeof(maxvectorsize))???

Thoughts? Ideas? Any help would be GREATLY appreciated!

* As an aside: I know that audio over internet can be done using TCP via jit.catch and then jit.net.send. Though, my goal is to see what would happen if i were to forgo quality as a means of minimizing latency. The C74 post describing the above mentioned process mentions not seeing any performance gains using UDP (wouldn't it be sooooo nice if they would release that code anyway?), but I'm wondering if there's a point, with super small vector sizes, that serious, synchronized live performance could be had, even if some packets are lost in transport.

I am trying to write an jitter external for Max 9 with Max 8.2 SDK. I have the problem that Max does crash when i use my external in a patch and i do not really know why? 

So is there a way to debug the external? 

Or is it possible to write some information from the jitter object or wrapper to the max console with a print method or something similar?

Or are there any log files where i can find some information about the reason for crashing max?

To brush up a bit my C++ knowledge and out of curiosity I started to dip my toes into the Min-Devkit.

As a starting project I chose to work on a new implementation of an object to connect to the ENTTEC DMX USB Pro, because it has a simple serial API and offers some interesting possibilities like multithreading, concurrency etc. One object I am working on is called [jam.dmxusbpro].

As part of the project I want to allow only one instance of  [jam.dmxusbpro] to be able to open a serial port to an  ENTTEC DMX USB Pro. 

The way implemented this is by creating a separate device manager class - a singleton - that tracks which devices are opened by which instance of  [jam.dmxusbpro] . That works fine between objects off the same class.

As a second step I am creating another object, called  [jam.dmxusbpro~] that allows to control DMX channels with MSP signals.

However, my approach of using a singleton device manager class only works within instances of the same Max object not between  [jam.dmxusbpro] and   [jam.dmxusbpro~].

Is there a way to share data between different Max objects using the Min-DevKit?

PS: I am working on MacOS and am using the POSIX termios API to open the serial ports.

PPS: Min-DevKit is a great addition!! It got me started very fast and is easily accessible for me who's working more in other languages and has a quite basic experience with C and C++.

i want to prepare my Laptop and GitHub repository for developing c-externals with Max 8.2 SDK, Visual Studio 2022 and CMAKE 3.23.0 for Max 9.0.4. on Windows 10. Therefor i want to clear some points:

I have cloned the max-sdk in my Max 9 Packages Folder like it is described at

For developing my own c-externals i want to copy and rename existing source code from the 

 folder as a starting Point for modifying the code for my needs. 

After finishing the external I want to push my own c-external Code to my own private GitHub Repository.

But I don't really know how to implement that because the

I just started working with the min-devkit a little bit and I am running into a weird crash I don't quite understand (see code snippet below).  I am on Sequoia 15.1.1 on a 2023 M3 using Max 8.6.5.

If I send something out an outlet, starting with a string followed by a single number (e.g. float), that works. Anything else seems to cause a crash.

What I am trying to do is add a string before a list of floats so I can use [route] in max to further process the output.

Furthermore, when I use a string followed by atoms 

No matching member function for call to 'push_back'

referring me to c74_min_outlet.h line 282

 // utility: queue an argument of any type for output
    template <typename argument_type>
    void queue_argument(const argument_type& arg) noexcept
    {
        m_accumulated_output.push_back(arg);
    }


 to add a value to the end of it. However, if I look at the type of m_accumulated_output it is of type 

If I go to c74_min_atom.h it clearly states on line 319 that:

// We don't own the array of atoms, so we cannot do these operations:
    // insert
    // erase
    // push_back
    // push_front
    // pop_front
    // pop_back

I might have a fundamental misunderstanding here, but it looks like that if we deal with atoms we can't use 

, but in queue_argument() from c74_min_outlet.h (line 282) we clearly use .push_back() to try to add something to 

So, long story short: what is the correct way of sending something like:

std::vector<float> data = {....};
std::string routing = "data";

to_outlet.send(routing, data);

so in max I can use [route data] to process the output?

Here are the different ways I have tried to use this and the results:
