what do you mean should not be used in a daw 
i beg to differ, you can use it in a daw if you want. on my system sound comes out and I can record midi notes and hear what playing … why should you not use it in a daw ? been using it for years!!!
cavari,
to hear the sounds from the microsoft synth you may need to connect your outputs in the device menu only, thats it, check manual though.
