I've been working on my NSMBDS Hack, "Super Mario Journey," and I can't get my music to work. It plays in wrong instruments, some instruments had too high or low volume, and the volume for the songs are too low. And I was thinking that someone could do the music stuff (Plus the "BAHS") because that would be a huge help. If someone out there has expirience, Here's the two threads I followed, and the MIDI files are in a google drive folder.
