This, and I found the most important is the pitch bend / glide on the sub (this is a single note that is pitched upwards over a quarter note). That has the tendency to make a sub feel big because it will hit a range of sub-frequencies and one of them will sound huge on what you're listening on .

I just got an old maschine mkI, and I absolutely love it. I have been producing pretty much exclusively on the elektron machinedrum in the past (and ableton chopchopping when arranging), and the maschine is like a machinedrum which can control vsts and has an insane library of samples and drumsynths...
