It also sounds very Motif-ish!

The iPad control is great but soon, we could see a musician with a multi iPad set up all around them!

iPad Pro running tracks and displaying the charts.
iPad Air controlling your mixer.
iPod Touch for your singer... controlling their monitor mix.
iPad Mini to control the sounds in your 88 key digital piano.

It's great, don't get me wrong. But it can get even more expensive and more complicated. Plus, you have to keep them all charged and updated.

I feel the manufacturers are making products to include a tablet device just because…#1 - It is the current craze and has a "cool" factor... #2 - It saves them a bunch of money by not having to incorporate the cost of a touch screen. Increases their profit margin?
