Kaossilator Pro Computer Hookup Help

[Psytopsy]

Hello, i recently bought a used kaossilator pro and am completely new to how to hook it up to my computer and record with it. I want to hear it through my computer speakers(speakers hooked up via USB), and record the sounds i play. I'm not trying to use it as a midi controller, all i want to do is properly hook up my kaossilator and record the sounds coming out of it, either in audacity or presonus studio one artist.
I'm completely lost on how to do this, but i have the following hardware:
-male to male rca cable
-usb cord for kaossilator
-rca to 3.5 mm cable(have 1/4 adapter if need be)
-male to male 3.5 mm cable
-edirol audio capture ua-20 interface
-regular toshiba laptop

What combination of hardware/audio settings will allow me to properly hook up my kaossilator and hear it and record with it? Thank you!
