Just got it so I am only in the learning process
While I have a PA90 and a PA1xpro and they are all similar, there are enough new features that I am still discovering what this instrument can do.
It is very responsive and quick to read both right and left hands at the same time. Problem for me is that it resets itself every time you change the voices or the style.
As far as portability, since I don't like 61 keys, I have to deal with a little extra bulk and weight for moving.
All in all, I was am very happy with the value and the fact that I have a new toy...
Hope this helps... WW
