LOL... playing a MotifXS/XF is an exercise in frustration!
I keep hitting the dang screen constantly, then go 'Doh!'
Mind you, as I said GUI is critical. I played a Kronos recently, and found that many, many mission critical things are way too small to accurately hit in the heat of live playing. The main "performance" quick select is nice and big, but most regular stuff is TINY and cramped compared to the PA3X.
The screen may be bigger, but cramming too much into it has ruined the entire experience, for me at least.
