This is pretty cool because now you can create a GIGA slave computer with a sound card under $100 with 4 high quality stereo pairs out. I discovered this sometime after I downloaded the latest drivers (previous versions were not GSIF compatible) and was building up another slave that was supposed to be used with Kontakt (which does not have any driver hangups). Then I tried out GIGA 2.x and whatdoyaknow! It is now GSIF compatible! I tested everything out and it sounds and works as good as my other high end sound cards. Sweet! I know nothing about GIGA 3 compatibility, but in theory, that should not be a problem.
