An iPad, a couple of cables, and a flic button…
… BOOM! That plus iQ Pro is really all you need to control your entire show. I use a 9th Gen iPad (it still has a 3.5mm jack) so connecting to the sound system at my residency and controlling the audio I need is super easy. But this does so much more than control your audio and it does all of that just as easily. I honestly believe this is the future of show controls. Not just for individual performers, but for venues too.
