Hi
I have to agree that the pianos are not THAT bad.. And if you get the Session-board, the piano there is really nice in my opinion.
Actually, I have to confess that most REAL pianos I have heard sound far worse than the Session-piano. To me, the average real piano has a boring, slightly out-of-tune sound where it is hard to spot any details. They have a natural low-dynamics, mono kind of sound, that totally fail to impress or interest me..
What I am saying is that the Session-piano has a richer sound than the real pianos most of us encounter..

It imitates a better and more expensive piano than I have ever played..

Just my opinions..
