The great thing about Midis is that you can do all kinds of amazing things with the different sound channels.
Ever heard of iMuse? (
Interactive Music Streaming Engine)
It's this amazing music system that was used in a lot of Lucasarts' Adventure games like Monkey island 2 or Day of the Tentacle.
It could do things like dynamically add or remove instruments to the song without halting it...
But the best part about it was that it allowed for the music to seamlessly transition from one song to another whenever it needed to.
Take a listen:
No matter when you leave an area, the transition will follow almost immediately, and it never feels like the songs are just being patched together.
It's really amazing and I'm so sad there hasn't been another game with music transitions as beautiful as these!

It took a lot of work too! The composer had to write a ton of different endings for each song but it really pays off.
Sadly, the Special Edition didn't manage to recreate it very well. Leaving the main area only has one transition for every point in the song.
Thing is, depending on which soundfont you use, Midis can sound radically different. So technically, if you had a chiptune soundfont then you could have both.
