It's easiest to do in a DAW like ableton (there are a ton of tutorials out there that show you how to do it)...
Basically the kick will trigger the compression on the bass which causes it to duck out of the way.
You can sort of do it on the SP by applying compression to both the bass and the kick, and then turn down the volume of the bass. The compressor will bring the volume of the bass up, but when you trigger the kick, it will cause the bass to duck out of the way. You kind of have to mess with the levels to get it right.
