Music, by 
Heh. I remember you from VG Music! I also remember listening to your Lagunicus MIDI and going “…huh.” I meant to e-mail you from VG Music and tell you that while your MIDIs are 100% accurate…they’re only accurate as far as playing the PSM/MOD files in an external player. See, some of the files (such as Lagunicus/SongCD8) don’t play correctly outside of the game for whatever reason. So while your MIDIs are accurate in notes and samples, they’re also unfortunately accurate as far as the song errors goes as well!
Try zipping around the levels and listening to the music in-game if you want to fix your stuff, KDS. Like I said, they’re darned accurate, but not accurate to the in-game music.
