Comment (by ZvikaZ):

 Well, I have started debugging it.
 Unfortunately, I'm not a musical person ;-)

 If you could help me with this, we might solve it together.

 First thing, I run ScummVM with '--dump-midi' flag, which dumped all Midi
 commands issued by ScummVM to a .mid file (attached).
 In that file, the first few seconds are in the plaza, before entering the
 tunnel, then it's in the tunnel until about 20 seconds, and then back
 again in the plaza.

 When opening the .mid file an editor (I like Sekaiju), it seems that there
 are a bunch of 'Pitch Bend' commands after roughly 20 seconds from the
 beginning. I guess they are the source of the reverb.

 Do you know how to work with midi files?
 If yes - you can try and "play" with that file, and try to fix it in an
 editor.
 If you can pinpoint me to the point where there's a missing/wrong/extra
 midi command, I can try to trace it's source in ScummVM, and fix it.
 If not, we'll have harder work, but it's still possible, if you want to
 cooperate ;-)
