Although I did appreciate the tone quite well, I found that there was some difference in the responsiveness of the tone to my touch that I couldn't feel great about. When I used it with a software piano, there was significant improvement in this sensitivity. Obviously the dynamic range of the software piano was better. But touch sensitivity was definitely much better than 560 and evidently, the sensors do sense the velocities reliably, which otherwise would have sounded just the same in the software piano. So long story cut short : where can I find velocity curve tweaking in 560.
