Soundcard question

I’m looking at getting a new soundcard to link to mairlist. The soundcard needs to have 4 stereo connections. I always used internal ones, mostly the Delta1010, but that is virtually impossible to find.
I’ve been advised to go for an external one and was thinking about getting the Behringer U-Phoria UMC 1820 (Behringer U-Phoria UMC1820 USB/MIDI Interface at Gear4music)
Will this one work properly with Mairlist and what’s the best way of connecting it?

Thank you x

Maybe not really helpful, but I have the UMC1820 in another context and think it’s a great device. Just connect power and USB and you get lots of audio channels to assign in mAirList. Oh, yes, and install the driver, of course.
