Diki, it's for when you need more than the standard 16 (well 15 including a Master I guess) tracks of an SMF normally available.

For example, ambitious Classical pieces (using individual Orchestral instruments on each track instead of the "Full Orchestra Patch" on 1 or 2 tracks for a more authentic sounding and complex composition.
Even some highly orchestrated Pop songs could make use of it, particularly if they used samples.

Linking 2 SMFs would also eliminate the need for switching between more than one instrument on one track, to get around a 16 track limitation - say you needed 17 or 18 tracks - just one or two more than the "standard".

I myself wouldn't use it, but I could see it being a viable option for some people.
