Korg Kaossilator Dynamic Phrase Synthesizer HELP! (Mac)

[Teetowl]

Hey I have got a Korg Kaossilator Dynamic Phrase Synthesizer and I am trying to figure out how to record or put it into Band Camp or Logic Pro
Iv just purchased a USB to AUX as the white and red to both USB and Aux don't seem to work

Any pointers or any point in the right direction would be greatly appreciated.

Or is it that I need to buy a mixer in order to record it? Confused!
