For European games i suggest using LAPC-I/CM-32L... MT-32 has lots of bugs and is useful for early USA games mostly. The LAPC-I and CM-32L will work better , no "buffer overflow" and such
Also it have more sounds than MT-32 (sound effects).
I have some recordings i made with my CM-32L here:
The Armour-Geddon one is really great and i must say the Gods title music was well done by Richard Joseph regarding the limitations of LAPC-I/CM-32L.
Also here is two recordings of the title music from the Atari ST version of "Police Quest 2".. both YM2149 and MT-32 versions
