A .5 version beta for Windows. Great. My Macbook is amused. I have the iPad app, but there doesn't seem to be any way to switch FX processors. It's a mock-up, not an app. Is the Android one any more complete? By the way, Behringer's BC-Edit and DSP1100 apps have been in beta since 2009 and 1998, respectively.
All the same, the XR18 is on my buy list. They nailed the form factor and the feature set.
