Timaes, you mind re-posting that second one without the drums? 
Edit: I'm not a bass player, but I watched a few videos on things that bass players like to do. 
I decided to play with the articulations, "Sustain, Staccato and Slide"(Can't get modulation/portamento to work). 
Didn't change much but it sounds a bit better in my opinion. 
Here's the bass, separated.
