3 Painfully Obvious Reasons to Use Submixes on Your Force (MPC)
So i've purchased a few of Akai's Expansion packs so that I can get an idea of how AKAI approaches mixing on the Force/MPC software etc.
I discovered that they basically mix inside of their drum kits then essentially slap either a master bus compressor or a maximize on the channel. 
Look im no professional by far, however, i do know that you can get great results from grouping your like sounds and treating those frequencies/dynamics individually, The main way you would do that in any DAW is by using subgroups or busses. 
The force has this capability conveniently built in, however, mixing isn't just the only benefit.

If you're someone who routinely sends stems you know this is a very important piece. Without sending your tracks to submixes, the force will only track out every single track. Unless your engineer wants the full trackout, sending instrument groups to busses means you can export each individual buss for stems. 
This is also true for samplemakers, if you build your demo tracks around your sample, you can group all of your drums to one track, instruments to another etc. By grouping how you like them, you can make drum loops,samples, fx loops pretty quickly.
