Copy the appreggio and place it somewhere close on the piano roll another 2 times, making appreggio chord. Go for something dissonant, although a harmonic chord can have nice effects.
Have a low pass filter selected, turn the resonance up, and close the filter down until you are left with a rolling rumble.
Add some bass saturation or EQ
Sidechain to the kick but don`t overdo it.
Hey presto big rumbling rolling techno bassline.
I can provide pictures also if need be.
