Now that is a familiar mixer! The X Air mixers have a good reputation. They also use the same interface as the mixer that I use, which is the Midas M32c. Personally speaking, I like to connect it up to a computer/laptop as the desktop app is easier for me to use than the ipad app.
I'm sorry to hear that it had a hissy fit this morning for you. I hope that you don't have further issues like that as you have a good mixer.
For me it started as a weeb thing. I wanted to learn Japanese for the sake of anime, but it quickly changed. Now, I learn it because I find the language itself fascinating, and how it works with their culture.
