From the Top Crew homepage: "The music was not made with a tracker (since we had no MOD-playerroutine), but Divus Ianus played real instruments, recorded one after another and then we sampled the whole thing. That's the reason why the sound-quality is quite poor - we had to keep the Demo small enough for download (in 1992 14400 baud-modems were usual) and uncompressed sound in cd-quality would take too much space. Probably you'll experience problems with the music, because we didn't know how to program the Soundblaster-Card and therefore used CT-Voice (a program that's being shipped with the sound-blaster). Unfortunately it seems to work only on some really old soundcards and so I made the music available for download in mp3-format."
