Audio interface / mixer setup question

Okay so, fairly new to the gear-game. I have a TR-6s and a Korg Monotribe that I want to be able to tinker around with and record at the same time. My current audio interface is a Scarlett Focusrite 2i2. I use Logic Pro X.

I usually do this:

Korg Monotribe —> Scarlett (input 1, mono) —> computer (USB)

Now I want to add my TR6S to the mix but I want each track on the 6s to be recorded on a different channel (i.e. BD, SD, CH, etc.)

Question is: do I need a mixer with a ton of inputs to then output into my interface? Or do I need a larger audio interface? I’m not doing crazy complicated things yet, and my budget is not the highest ($200-300).

Thanks in advance for any help!!🥹
