Audio System Toolbox Plugin Generation Error

Hello,

I'm trying to compile an audio plugin to VST format to use it an a DAW.

Whenever I call the generateAudioPlugin function to do so, I get the following error:

??? Error evaluating the post-code-generation command.

Caused by:
    Undefined function 'isDouble' for input arguments of type 'embedded.numerictype'.

Error in ==> createPluginInstance Line: 1 Column: 1
Code generation failed: View Error Report
Error using coder.internal.generateAudioPlugin

Error in generateAudioPlugin

Error in generateAudioPlugin

I'm using Visual Studio 2015/2017 as compiler with this patch installed:

1568224

mex -setup outputs this:

MEX configured to use 'Microsoft Visual C++ 2015 Professional (C)' for C language compilation.
Warning: The MATLAB C and Fortran API has changed to support MATLAB
   variables with more than 2^32-1 elements. In the near future
   you will be required to update your code to utilize the
   new API. You can find more information about this at:

To choose a different C compiler, select one from the following:
Microsoft Visual C++ 2015 (C)  mex -setup:'C:\Program Files\MATLAB\R2016b\bin\win64\mexopts\msvc2015.xml' C
Microsoft Visual C++ 2017 (C)  mex -setup:'C:\Program Files\MATLAB\R2016b\bin\win64\mexopts\msvc2017.xml' C
Microsoft Visual C++ 2015 Professional (C)  mex -setup:C:\Users\willi\AppData\Roaming\MathWorks\MATLAB\R2016b\mex_C_win64.xml C

To choose a different language, select one from the following:
 mex -setup C++ 
 mex -setup FORTRAN

Thank you

Can you confirm the version of MATLAB you are using ?
