When starting a new game, a a few seconds into the music on the first playable screen, a note hangs indefinitely, and loudly, when using the MT-32 emulator or the GS Wavetable Synth . Saving a game and restoring it seems to get rid of that particular note, but it sounds like other notes are sustaining too long as well as the music plays.
When choosing Adlib, the one long, particularly obnoxious note isn't there, but it does sound like there are other notes that hang too long.
