The tones for String in the 560 are all dull and not upto the mark. Can anyone help me in editing the tone so as to get a better one? I would be really grateful if someone who already has a great User Strings Tone would post it here.

What should be the apt volume knob location so as to get grand/upright like touch to volume ratio? I neither want to pound the keys too or or too soft when I sit on an actual grand/upright.
