Performance Features

Touch Response for Keyboard Dynamics Control

Touch response On/Off

Keyboard touch response can be turned on by pressing the [TOUCH] button.
When touch response is on you can control the volume of notes according to how
hard you play the keys.
Press the [TOUCH] button a second time to turn touch response off. When touch
response is off the same volume will be produced no matter how hard you play the
keys.

Touch Response Sensitivity Adjustment

The sensitivity of the keyboard's touch response can be adjusted in three steps (1
~ 3). The higher the number, the greater the volume variation produced by the
same variation in how hard you play the keys — i.e. the keyboard becomes more
"sensitive."
Press and hold the [TOUCH] button for longer than a second until the touch
response sensitivity setting display appears.
Use the number buttons [1] ~ [3] or the [+] and [–] buttons to set the touch
response sensitivity as required.
