On the full-size grandMA3, we still have the three large touchscreens we are used to. There are no hard keys on the side to change views, but the on-screen View Buttons are still there. On the bottom are two Internal Multi Touch Command screens in the place where there used to be one display. My question – “Huh…why?” – was immediately answered by the operator showing me examples. For instance, you could be looking for a new color and pop open your options so that one screen has sliders for separate RGBW hues while the other screen may have a color picker. Or, say you want your effects library on one page and your effects programmer on another.
