I've built a cool object with MinDevkit with lots of functions, structs, and variables.  The file is getting pretty unwieldy.  I'd like to move a lot of this stuff to a separate header file, or ideally a  few separate header files.  So I can call my function inside the Message code, without loads and loads of preamble in the main object file.

But  with min devkit, we are essentially declaring a class, not defining one.  o basically what I'm trying to do is split a class declaration across multiple files.   Which is not great C++ style as far as I understand it.  I've tried a few different ways to hack this.  Some things can be externalized and some things can't, and the number of exceptions I'm encountering wind up fragmenting the code in confusing ways, which undermines the reason for doing this in the first place.

Any C++ Wizards know of a good way to take the entire private members section of class declaration and put it into a different file from the rest of the class?

I'd love to keep my main object file focused on attributes and messages and keep the gobs of preamble those messages depend on somewhere else.

Greetings,

I've been out of the Max game for quite a long while and looking to set up my current dev machine (Mac Mini M4, OS 15.x) for 

building Max 9 compatible externals, coding in C++

. My target platform will be MacOS only. I intend to figure out RNBO export some other day.

 I'm finding seems fairly stale. Written in 2022, it's talking about "new" support for M1 silicon and MacOS 10.15 (!).  Hoping some kindly soul would respond here with fresh advice on the latest/greatest supported (i.e. C74 friendly) versions of the various related tools. Or simply point to more recent docs in case I've overlooked them somewhere.

I have to assume that someone out there is happily and successfully building stuff on current generation MacOS + hardware. Will be most grateful if such person wants to save me (and any future travelers) a bunch of needless trial and error on this :-)

current/latest tools+SDK for building C++ Max externals???

Shakeeb Alireza

One of the long-standing objectives in my 

 (python3 externals for Max) project is to have a way for Windows user of the library to build relocatable python3 externals which can be used in standalone and packages. Various methods for doing this are already provided for macOS users, but presently, Windows users are only able to link python3 externals to local python3 installations.

Recently, I've been chipping away at this problem and have just developed a way to link a python3 dll to its dependent dlls in the 

 folder of a package which is along the lines of the 

Everything works as it should except for one thing: I had to basically treat the 

 folder as the direct container for the dlls. So instead of 

<package_name>/support/python/python313.dll+related files

<package_name>/support/python313.dll+related files

Is there any way to specify a subfolder of the 

 folder to be searchable for dlls without disrupting the dll search order of the Max application?

 without much success, and as I am far from being knowledgeable about windows, I would appreciate any help that would bring me closer to a solution.

Is there a way to add a folder in the support directory to the Max dll search path?

I’m working on developing the template made by Stefan Brunner that lets you « convert » RNBO patches to VST using juce (

https://github.com/Cycling74/rnbo.example.juce

During the development of my solution, I debugged with Max, with a vst~ object in it that allowed me to open my plugin without any problems. The templates now runs how I want it to, builds and run like a charm. The only problem is that the VST that it outputs seems to not respect every rules (?) needed for it to work properly. Let me explain. When I first compiled the code, I tried to open the plugin in Live, didn’t work, opened it in Max and Reaper and it worked, so I chose to develop using Max and focus on that problem later. Everything worked fine, I even linked max to an Xcode Scheme, and it provided a really smooth workflow. Now that I’v finished this phase, I want to fix the bug I’ve had since the start. I’ve tried to debug using pluginVal 

https://github.com/Tracktion/pluginval/tree/develop

https://github.com/steinbergmedia/vst3sdk

), and it doesn’t seem to see any problem.  

Still, the VST doesn’t appear in Ableton Live. Trying to see what is wrong, I went into Reaper to open it. It worked a few times, but without the changes I implemented to the template (and auto. GUI). Then after a few trials, it seems that it is keeping a version of the VST and not changing it (same name, same UI), even when I change the version in my Plugin folder (I tried every re-scan options)… I really don’t know what is happening, and would really appreciate some help.

I'm using the RNBO export function and the VCV rack SDK to translate my RNBO patches into Rack modules. I'm trying to hack a little bit into the system (module.cpp, rnbo_source.cpp and others) in order to be able to control the appearance of the final module directly from the parameters or in/outlets metadata field. 

The issue is that there is no implementation of the "meta" field in the rnbo c++ export. Well, it does exist in the "description.json", but there is no solution implemented to access it easily, meaning that the field doesn't exit in the "rnbo_source.cpp", neither in the "ParameterInfo" struct in "RNBO_Types.h" : 

struct ParameterInfo
	{
		ParameterType type;
		IOType ioType = IOTypeUndefined;
		ParameterValue min = 0.;
		ParameterValue max = 1.;
		ParameterValue initialValue = 0.;
		ParameterValue exponent = 1.;
		int steps = 0; // 0 = continuous, 1 = toggle, 2+ indicates steps in the normalized representation
		bool debug = false;
		bool saveable = false;
		bool transmittable = false;
		bool initialized = false;
		bool visible = false;
		const char **enumValues = nullptr;
		const char *displayName = "";
		const char *unit = "";
		SignalIndex signalIndex = INVALID_INDEX;
	};


As these files are generated by RNBO during the export, I cannot modify them in order to have the informations needed. I don't want my first option to be to parse the .json file... Is there any way that I could get the metadata directly from the RNBO export in a way similar to the ParameterInfo struct ?

Getting the RNBO parameters metadata with a getter from the rnbo_source.cpp (or similar)

 there is mentioned a "value" attribute.  Can anyone share some additional detail on what this attribute is and what it does?

I discovered that it only works if the type is set to "number".  Otherwise it returns a funky compiler error. 

To my knowledge, pattr can handle all the attributes of an object, including attributes of any type.  Not simply number attributes called "value."  So I don't understand what this attribute would be used for.

I am writing a UI object, and I'd like to persist a string between sessions.  Save the string with the patch, and recall the saved string on load.

I think the "savestate" message would be ideal for my purpose.  But I also discovered that "savestate" doesn't work with UI objects.  So I thought maybe persisting the string through pattr using this "Value" attribute might be possible.  But I'm not really understanding what this is or how it works.

Ideally the string would be internal to the object, and so not externally represented as an attribute, but at this point I'm willing to consider anything.  

In the Min Devkit docs there is mentioned a "value" attribute.  Can anyone share some additional detail on what this attribute is and what...
