I agree with DNJ about the piano being the least used instrument (voice), at least during MY performances.

I still use a pedal, though, but for right hand instrument effects other than sustain. Most of the time I'm using various combinations of guitars, saxes, vibes, strings, and some custom voices I made. One of those custom voices is a grand piano with a strings layer, which I frequently layer with vibes. I guess everyone has their favorite right-hand voices. Of course, there is another pedal for the vocal harmonizer as well. You can do lots of neat things with pedals, but you can do those exact same things with registrations too.

Cheers,

Gary
