Can the standard version of the Audio Weaver write custom Modules?
Only the Pro edition of Audio Weaver Designer supports custom module creation.
Should I be able to launch and run the server from inside matlab with the standard version (evaluation)? None of the scripts seem to work.
No, the Standard version of Designer is a compiled MATLAB executable that is run by the MATLAB Compiler Runtime (MCR) provided as part of the installation. This means that you are able to run this edition of Designer without MATLAB installed - but it also means that you cannot use an instance of MATLAB to interact with Designer, as you can with the Pro edition.
To launch the Standard edition of Designer, simply double click 'awe_designer.exe' application in the Designer install folder. Or, to launch just the server, double click 'AWE_Server.exe' in the '<install_dir>\Bin\win32-vc100-rel' directory.
