Logic on iPad is really incredible. My 2018 11" iPad Pro is able to power a Tascam US-2x2 over USB C - including an attached XLR mic, receiving its input as well as MIDI from an attached keyboard. No auxiliary power...except on the powered studio monitors. Using an iPad to power all of this really brings up some interesting opportunities around ergonomics and setup. I no longer need a full laptop or desktop for this.
