Hiya devs, I just wanted to follow up to find out if there was any progress on docs, examples, and/or SDK support for Arrays and Strings, or if there is a projection for when we might see such a thing. It would be great to add support for these to Scheme for Max soon.

I'm trying to port my old sfmarkers~ external to ARM and just noticed it doesn't work for AIFF files since some Max versions.

I does work with Max8.1.11 but not with 8.3.3 and later (on intel, 64bits).

As far as I still understand my 20+ years old code,  the call to 

 pointer in the _sndfileinfo structure, even if markers are present in the soundfile.

Did something change in  sndfile_info() between Max8.1 and Max8.3?

It currently has one external (chuck~) with the following features:

- Generate and process audio via an embedded chuck engine by running chuck files with `global` parameters adjusted and controlled in realtime via Max messages.

- Layer sounds by running multiple chuck files concurrently.

- Add and remove audio and audio processes on the fly via Max messages.

The project's repo is: https://github.com/shakfu/chuck-max

While this is not a release yet of the external itself, the repo contains all of the external's dependencies and is very straightforward to compile using the standard Max SDK build system.

Fantastic! This is really great work you are doing. This may actually get learning chuck to buble up high enough on my list! :-)

Reminds me I need to do an M1 version of the Csound6 object..... 

Thanks, Iain. It's nice to work on audio externals for a change (-:

I'm writing my external object in C hoping to receive any message(even with spaces in it) and transfer the message into one string so that I can do data process in C. I have looked at some chapters in MaxAPI  and did some test. Seems max likes to take the message and transfer into atoms which I do not need. I just need the raw data. Can anyone help? Thanks~

I'm writing some externals in c++ using the min framework. I want to make an external to be used in a Max4Live patch. The external will take a prompt as input and generate a composition as a responce. The composition should be based on the name of the tracks in the live arrangement (this will tell the model which instruments to write for). Next the score for each track will be placed in midi clips on the relevant tracks. 

I cannot find the information about how to interface the LOM directly from an external ?

If you've worked with Min Devkit enough to recognize how awesome it is, you might also have run into a few of its limitations when working with Max's more advanced features such as dictionaries, notifications, UI objects, etc.

Min Devkit is a wrapper around Max SDK, and in fact, the entire Max SDK Base is included in the min-api folder.  Mixing and matching Min Devkit and Max SDK takes some care.  There are also there are a few essential, undocumented, setup components that need to be addressed before you're able to do anything substantial here.  The notes below are assembled from my learnings across several threads in this forum.  Thanks especially to 11OLSEN and Rob Ramirez for all the support.

Two Methods for Using Max SDK in Min Devkit Projects

1)  Call Max SDK Functions in Min Devkit Source Code

If you want to use a feature of the Max SDK that isn't fully implement in Min, you can call any Max SDK function by prefixing it with c74::max.  For example: c74::max::object_notify().

Follow these suggestions and you should be able to leverage most of the Max features supported by MaxSDK inside MinDevkit.

2)  Create a Max SDK Object in a Min Devkit Solution

Sometimes calling a few Max SDK functions inside a Min object is not sufficient.  Min's support for UI Objects is either incomplete, incompletely documented, or both.  You might run into something that can be done in Max SDK that is very difficult to achieve in Min (textfields  are a good example).   In this case it can be easier just to build a Min SDK object and include it  in your MinDevkit package.

There are probably a few ways to do this. Below is my preferred solution:

1) Create a new Min Object the way you normally would.

2) Delete the contents of the source file.

3) Replace the contents of the source file with well-formed Max SDK source code.  Ideally, paste in an entire example from the Max-SDK.

4)  Somewhere early in the ext_main function you will find the line where class_new() creates the class.

In the simplemax example from Max SDK it looks like this:

c = class_new("simplemax", (method)simplemax_new, (method)simplemax_free,  ....

The first argument, the string in quotes, needs to match the name of your file.  So if your source file is "MyNewObject.cpp" then the first argument of class_new() should be "MyPatch". eg:

c = class_new("MyNewObject", (method)simplemax_new, (method)simplemax_free,  ...

You can replace the name of your template (in this case, simplemax) throughout the code, but the only one that matter is the first argument of class_new().  If you don't do this, your object will appear red in Max and there will be no indicator as to why.

5)  You could stop here, but it's possible to go a step further.  Delete all the includes from the top of the file.  Replace them with: 

Now we are literally running Max SDK inside of Min.  We could even call Min functions inside it using the  c74::min:: prefix.  (Very cool in theory, use in practice at your own risk)

Most importantly, the new Max SDK object is running entirely on modern C++ which means you get access to the C++ standard libraries and any third party C++ libs you want to use.

The same concern about common symbols applies.  Be sure to include 

 in your cmakelists.txt as described above.

. Include this as well using the same method.

Your cmakelists.txt for a Min object that uses Max SDK to create a UI Object should have the following:

	${MAX_SDK_INCLUDES}/common/jpatcher_syms.c

Armed with this, you should be able achieve anything Max SDK is capable of inside a Min Devkit Package.

I hope this is helpful to someone.  I offer it as gratitude to the folks who helped me figure this stuff out.

Using Max SDK in MIN Devkit Projects:  A How To Guide

I'd like to create a custom UI object that has multiple text edit fields.  

Context:  My externals connect to a cloud service to enable access to data from that cloud in Max.  In order to connect we need to gather user auth credentials.  I don't really want to use Max's standard textedit objects for this.  Because distributing patches that pass user's sensitive data trough patch chords seems like a bad idea.  I want to build a custom UI object user's can type into so masked  data remains at the code level and is never accessible in the patch itself.

 example in the Max SDK.  I can definitely use this as a starting point.  It will be easy to modify this to mask the data onstream, and pass the the user input to other objects using the notification system so it's never exposed in the patcher itself.   I could use 2 or more objects based on uitextfield to compose a bpatcher that will serve as my Authentication screen.

Problem:  It would be better for the Auth Screen to be a single Max object.  The default textfields are fairly nondescript.  If I distribute my patcher, a nefarious actor could swap out my custom textfields with some other textfields.  The auth screen would look unchanged, but the user has just typed their credentials into an illegitimate input field.

The Question:  I'm not seeing a way to include multiple textfields in a single object.  In fact, making an object a textfield seems to overwrite most of paint's other functions.  Is there a way to compose a UI objects from multiple component UI Objects?  Or a different way to get multiple textfields into my object?

I'm aware that instead of using textfields I could paint text directly and repaint based on the key methods.  But this results in some behaviour that don't feel natural (like being unable drag over and highlight the text).  I would like this auth solution to appear to be as seemless and native as possible.  

I know I've posted a number of similar threads on this topic.  Thanks to all for your input!

Greetings,
