<< The Ui24R is off-topic as it's a 24-channel mixer, not a sound card.>>

It shouldn't be off-topic. The The Ui24R is a quite robust audio interface that's well suited for both this discussion and use with BIAB/RB or any DAW as a digital multi-track recorder.
Mackie, Yamaha, Korg, Zoom, Behringer and Tascam all offer Mixers with USB audio interfaces that offer good pre-amps and analog mixing, digital Fx's, aux outs, Groups, Busses, and recording direct to flash drive or SD cards and multiple routing options.
