These are two a bit less known games with music specifically composed for the LAPC-I/MT-32:
Lord of the Rings: Two Towers
complete XMI music by Charles Deenen:
the .rol are the LAPC-I versions, .adl are Ad-Lib/Sound Blaster, .pcm are PC-Speaker.
All the files are in fact *.XMI and should sound correct with one exception - they all play 2x slower. In order to make them sound right you have to increase the tempo just 2x (or listen to them while playing the game). Otherwise they're OK.

But they are maybe slightly modified, so may not sound correctly while played by regular MIDI player, as I haven't the MT-32 I couldn't test it. There are also some .prf and .ins music or bank(?) files unknown to me, maybe the MT-32 owners will know what they are intended for, so I uploaded the whole directory with MIDs.
