Sample question

Hello everyone, first post here.
I'm kinda struggling with the inputs on my Touch.

I want to hook up my tt as well as my Stanton C.324 for sampling into my Touch.
My question is how to do this because the Touch has only one (L+R) input.

Do i need a mixer or a soundcard (i have a M-audio M-track) with multiple inputs/outputs?

Thanks in advance

No one?

Use the inputs on the mtrack to sample the c324 or you can swap out the turntable for c324 cables from the touch each time you want to sample. Getting a mixer is an option.
