I've been using my XR18 for smaller gigs. It's been rock solid with the external Airport Extreme I'm using for WiFi control. Effects sound good too. Haven't had a single hiccup yet under mission critical use. They have a few more features to add to the iOS/Android apps to get parity closer to the functionally of the PC/Mac desktop control apps, but it's almost there. I keep a touch screen laptop hardwired to the router along with my iPad for floating around. Great setup. Beats dragging out the Avid Venue for smaller gigs that don't need the I/O count.
