NOTE This is not the 2k Whine bug, this is a DEAD unit!DONT BUY IT, buy a Behringer u-phoria 4 input instead, you can still connect an ipad and buy a lighning usb adapter with power in and your set,Bitterly disappointing, I have a $450 AUD paperweight with some nice USB cables

I also got it working great with iOS, but I'll admit it did take my fiddling with a few buttons, realizing that you have to select the right USB port and turn up the volume because it's off by default.

As it stands, I can’t recommend it over a more-simple class-compliant USB audio/MIDI interface

They determined it was the fault of a bad USB cable that had fried the board
