QU Control is different. It allowed me to populate a screen on my iPhone with fader level and mute. With my QU 16 I hade a screen with just level and mute for our main vocal mic and another level control just for the bumper music between sets. It allowed me to be lazy while at the bar drinking during breaks, and if there needed to be an announcement, I could control it from my iPhone. And if the bumper music got too loud or soft, I could pull out my iPhone and adjust, I do have mixpad on my iPad, but I have it wired to an input as I use Garage Band to play keyboard parts during the show. Take a look at the QU control app and you’ll see the difference. I was hoping for an SQ control so I could get back to my drinking.
