X AIR XR12 : Best buy of the year!

This is an amazing mixer. The sound quality is fantastic! I have used a number of controllers to operate it and they all work well. Using the computer gives the best access to all the features. I use an iPad for gigs. When the battery died on one occasion I used my Android phone as the mixer, no problem. The only and obvious drawback is the smaller the controller device the more difficult to move the faders accurately. There is a feature when you hold your finger on a controller it enlarges to a slider the width of the screen. Brilliant! I now also use the mixer at home for recordings. My Rode MT2A has found new life! It really sparkles. I've read about people having a few problems using the internal WiFi. Works perfectly for me! I can highly recommend this mixer.
