How would I connect a Korg Volca + NTS1 to Logic?

[Onnix]

I've got a Volca Keys and NTS1 hooked up together so the NTS1 is used for FX but I want to record into Logic. Both units are connected via a 3.5mm so would I need a Y splitter so it's like:

Volca Keys Master - Y Splitter to NTS1 then the other part of the Y spliter goes to the instrument in on my Air 4 audio interface?

I assume the cable that goes from the splitter to the Air 4 would be a standard TRS cable?

Thanks!

Why do you need the splitter? If you want to record the Keys 'dry' ie without the NTS-1 effects, then hook the Keys output to your interface. If you want to record the Keys 'wet' ie with the NTS-1 effects, then hook the NTS-1 output to your interface.

But with this splitter, you're making it sound like you want <some unknown thing> to be done with the wet sound, but record the dry sound anyway? Huh?
