How to get Less Harsh sound in Gate Pad Polysyn?

I’m trying to get the bass line sound from the song by Hillsong United: “Relentless,” and the “Gate Pad Polysyn,” is the closest sound in Cubase LE AI Elements 8 I could find, but its still too harsh, is there any way to make it sound like that bass pattern in that song? Just a little less harsh, or any other sounds like this? This sounds similar to retro music but still cant find any sounds in cubase that are like this where it keeps a steady beat too… What do you all think? Thanks!
