I was told:

"So not having the sound hitting that loud ceiling (velocity control numbers between 110 and 127) might help slightly for sound and feel."

What should I do to modify this on my RD-700SX?
I was also suggested to set the Touch to a harder setting and that feels a little better.

I have these KEY TOUCH(/VELOCITY?) settings on my RD-700SX:

KEY TOUCH: (Goes from Super Light to Super Heavy)
KEY TOUCH OFFSET: (Goes from -10 to +10 for each key touch setting)
VELOCITY: (By default says REAL then goes from 0 to 127)
VELO DELAY SENS: (goes from -63 to +63)
VELO KEYFOLW SENS:(goes from -63 to +63)

What should I tinker with for maximum touch, feel, sound like that of a piano? RD-700SX users?

I also have an onboard equalizer maybe I can tinker with that some in order to get a good sound. What are the RD-700SX users doing?
