Not getting some sound effects with General MIDI (but it's working in DosBOX)

[ZvikaZ]

Hi.
Tried playing Gabriel Knight (CD/Dos and Windows/English) with General Midi (tried FluidSynth [with FatBoy 0.786, and some other SF - 'Roland SC-55 v3.7.sf2'] and with MS Windows MIDI) - the music is great, but there are no sound effects when I get points.
Tried changing to MT-32 emulator - the music is good, but less than GM - however, now I get these sound effects.

The "Mixed Adlib/MIDI mode" is clicked in ScummVM general options menu. (It doesn't show in the game's specific options menu - is that the source of my problems?)

Tried with DosBOX, and in Sierra's original install utility there are separate settings for "Music" (I chose General MIDI) and "Sound" (chose Sound Blaster) - and it seems to work fine (there are some other issues with DosBOX - I really prefer using ScummVM - but the music/sound issue is better with DosBOX).

Bottom line:
It seems that there is a problem with '--multi-midi' option here.
