I did gig with the PA1xpro, and I loved it. the sliders, the vocalizer. the layout.
But these things I hated.
1- the PA1xpro went for that live band sound, like a trio, which at times were great, but other times I found myself adding a string pad to fill, I know that seems to kill the idea of hearing each instrument instead of a wall of sound but i needed to do that allot. maybe because my playing didn't help/
2- selecting sounds other than the 4 programmed for a style seemed to have extra steps that made live play a little slow
3- midi file playback was awful, you really needed to re-program the program changes to different instruments, but once you did, it did come alive, I would say Roland/KEtron then Yamaha/Korg
4- touch screen wasn't as good as the G70. the G70 was the perfect touch screen, with beep and a quick response. the target just seemed easier to hit with the G70
all in all if you don't mind the set up and programming time to make the PA1xpro yours, don't get it, but if you have the time and the effort, it was one of the nicest sounding arrangers I've owned
