In my case, the piano is the least used voice on my keyboard. I use the growl and sweet tenor sax a lot, several guitars, harmonica, flutes, strings, brass, trumpet, lots of neat things other than the grand piano. When I do use the piano, more often than not, I have it layered with strings, which IMO, provides a lot of depth and quality.

Beneath the keyboard are two foot switches, one for the Harmony-M and one for the keyboard. Most of the time the one connected to the keyboard is set to harmony/echo, which is sometimes used for the piano voices.

It's not that I don't know how, when, or cannot use the sustain, most of the time I just don't feel the need to use it.

Cheers,

Gary
