Fig.1b – The same bass pattern but with a staccato feel. This technique gives you a more mechanical sound, is like cutting the sound of each note. Notice that the bass is matching with the hi-hat pattern.
Fig.2a – An example of a 12/8 feel. The bass drum and the snare are played in the downbeat of the triplets, while the bass is punching the downbeats with dotted quarter notes.
Fig.2b – The same progression but playing the root on every triplet. This will give you a more driving feel to the groove. Don’t forget the accented notes in every downbeat.
Fig.3a – Here’s a very simple groove where the bass is punching the kick drum on beats 1 & 3. Note that beats 2 and 4 are in silent and giving a sense of space to the groove.
