Connection suggestions for DT, SP404, and Maschine mk3?

Whattup! Hope everyone is well. I’m seeking some advice for connecting a setup. Here it goes:

The gear: Maschine Mk3 (usb connected to my computer), Digitakt, SP404 mk2, turntable for sampling vinyl, Komplete Audio 6 interface.

I’m hoping to connect everything in a way without having to buy a mixer if possible. I’m looking for the best possible sampling workflow where I can sample my turntable, DT and Maschine into the SP and then back into my Maschine/computer after further processing.

I’m going to pickup the SP404 today and I have an idea of things i’m going to try but I’m pretty new at this and figured id make this post to see if any of you had any thoughts you’d feel like sharing on the matter.

I’ll follow up with what I’ve tried later today if I can.

Thanks!

Personally, I’d sell two of your samplers and buy a synth. Or just stick to Maschine where you get everything in one box.
I just sold my SP404Mk2, so I could buy a hardware synth to pair with my Maschine.

Keeping it simple is usually the best way to go.
