Mine's probably set the highest here at D below middle C. I need that room for playing bass lines and it still leaves me with 3 octaves to pound out chords with my right hand. I need 2 octaves to play juicy lines that move all over in the left hand.
I also have my RH section transposed an octave lower so anything lower than the lowest Eb is muddy anyway. This is the best range to compliment my vocals. Sometimes when I solo on a piano sound, I pop the sound back UP the octave to get a nice bright feel, then back down again to comp.
