Help the groove.
Sometimes, when producing using midi driven VST or hardware synths, specially when midi was quantised, groove can feel a little weak, maybe, too cold, like missing the human feel of music. One way to help the relationship between the kick and the bass, is to insert a delay in the bass track and setting the delay time somewhere below 10 ms (to my taste, 5 ms works great!). Just make sure that the delay is 100% wet, and no feedback. This will help to make you move your feet!"
