I usually write up my grooves in the drum editor or guitar pro 5 and after the writing process I just brutally get them to 127. Ghost notes and snare as exception.
Oh and this too! This is a thing that adds the groove to the machine:
When the drums hit cymbals in tempo remember to add notes in "between the metronome clicks". Many non-drummer writers type grooves out so that the cymbals (for ex. hi hat) in the same tempo as metronome does, but every drummer knows that you actually hit the cymbals double the speed. It's just that the hits that are between the "metronome" hits are a lot lower on volume.
Ghost notes on snare gives a bit to that feeling also! Remember, you are trying to simulate a human, not a machine.
