Bass is the place. The miniKORG (recent version) does bass so well. This fourth Logic Sampler instrument has a name that describes it, Square But Nice Bass.
The samples are short, with 3 round-robins, spread out by one tone over 4 octaves. I've included the option of adding some of the built-in Drive by using a Modwheel.
Please read the Read Me, as it contains the Installation instructions.

You can hear this instrument in this short demo I made, featuring all the Sampler instruments of the week (minus the drums/percs) :
