I was lucky enough to find a relatively good priced MT-32 and SC-55 which I have been looking at for a while now

I am still waiting for them to be shipped to me, but I'd like to prepare myself a bit while waiting.
One thing I have done is creating the MI 1/2 "Ultimate Talkies" based on the Steam versions of the deluxe gamle so I can have both speech-audio and MIDI.
The reason I am writing today is to ask if anybody can clear up:
1) Besides MI1/2 which versions of the do I need to get Midi for my devices. I read somewhere that the CD version of some games does not use midi but recorded audio. I believe it was Indy. Is there a list somewhere that clears up which titles comes with midi?
2) Besides the LucasArts games, Space Quest series, and Beneath a Steel Sky which other ScummVM compatibble titles has either good MT32 or GM/SC-55 productions. I'd love some recommendations on new games. I would love to hear your fav. MT-32 and SC-55 titles.
I will use the hardware on my old iMac G4 20" which I have upgraded with a SSD and 2 GB ram. Hope it sounds better than when I try to emulate the MT32 on the old G4;)
