1. Yes

2. No.
I don't know what the Pa1X Pro does but the T2 has the ability to kind-of play samples. I say kind-of because it only accepts a limited type and it is unacceptably slow in loading any thing of significant size. If you want the ability to use sounds other than those supplied I would look elsewhere. That being said, I find that T2 to have OK sounds and some standouts and some a little lacking. Of course that is all subjective. Acoustic Piano, Acoustic Bass, and clarinet I find lacking.
