Behringer UMC 1820 works great with iPad mini 4
I setup my new Behringer UMC 1820 with the iPad mini 4 last night. I got it to replace the Roland UA-22 + USB Streamer combo that I was using with my Expert Sleepers ES-3/ES-6. Since both the UA-22 and USB Streamer are audio interfaces, I couldn't use them both at the same time. The UMC 1820 is like having both the UA-22 and USB Streamer combined with many more inputs/outputs. With all these channels I can use AUM to apply different effects to each of my hardware synths plus have the ES-3/ES-6 for sending/receiving DC-coupled CV (or audio) to and from my Eurorack modular using the ADAT connections. The only issue I had setting it up was that I didn't realize it doesn't override the iPad's audio so I wasn't getting any sound from the unit until I cranked up the iPad volume. This was a bit strange, since all the other audio interfaces I've used disable the iPad's volume buttons.
