I have an iPad Pro 12.9". I'd like the ability to display two views at once, e.g. Sampler and Mixer.
This could be similar to the way the keyboard is shown below the Sampler currently (although I find that a bit hard to use, even on my big screen). Perhaps with some sort of resize control to control the split area.
I've used Ableton Live with Touchable and split views really help in hectic performance situations.
