Record synth session ... USB mixer or sound card?

Hi dears
I'd like to record my session and experimenting with ambisonic and audio360.
My setup is eurorack modular (from vca out ti mixer), model-d and some DIY stuff. All mix with xenix1200fx
I'd like record every instruments in differenti traks.
What is a good solution on budget for recording?
Is Better an USB mixer like ZEDi-10FX (anybody use it?) or a sound card?

Thanks and synth the world

I use an ES-9 to send everything to my iPad, where I use AUM to mix it. AUM can also add effects, side chain compression, etc, so I'm finding it very flexible. With it, you can record each track separately. I also send everything to a mix bus, on which I apply a final EQ (removing hiss if necessary, for example), and I record that as well for publication.
