What is the Leading Bass function?

The function that sounds the lowest note of a fingered chord as the bass tone is called “Leading Bass.” When set to “ON,” the bass tone changes when an inverted chord is used.

Usually the tonic of the fingered chord is sounded as the bass tone.

→If you’ve assigned “Leading Bass” to a pedal, the Leading Bass function is active while you depress the pedal.

→When the “Bend Up” or “Bend Down” function is used with Split (p. 55) selected, the pitch of the sounds played in the right hand are then altered. Additionally, the maximum degree of change in the pitch when the Bender effect is used is called the “Bend Range.” Take a look at “Changing the Bend Range” (p. 152).

What’s the Bend Range?

The effect of smoothly raising or lowering the pitch of a played note is known as the “Bender Effect,” and the pitch’s range of change is called the “Bend Range.” With the KF-90, you can apply the bender effect by depressing and releasing

apedal.

*Pressing the One Touch Program [Piano] button returns the pedals to their original functions (p. 16).
