Analog Four MKII as an audio interface + Eurorack + VCV?

Hello,

I’m learning before buying my first rack.
And just saw the video by loopop and make me think of the possibility to use A4 as an audio interface so no need of any interface (Motu in his case for the ADAT) + Expert Sleeper ES-8, right?
And the use of OB…
Any one can confirm or even try this workflow?
Thanks)
