TBH, I never really used it. ? It is working, but I never owned a GUS back then, and the only thing that interested me was to get MT32 emulation working. So I didn’t really listen to GUS music. Come to think of it, I’m not even using MT32 much, only in games I play for the 1st time. In any games I played back then, I always go for the Adlib/SB sound I remember so fondly. 🙂
