Casio CTK-4000 User Manual

Playing the Digital Keyboard
E-10
Touch Response alters tone volume in accordance with
keyboard pressure (speed). This provides you some of the
same expressivity you get on an acoustic piano.
■ Sound intensity depends on the speed that keys
are pressed.
People normally believe that the stronger the pressure applied
to a piano keyboard, the louder the sound. Actually, however,
the intensity of the notes played depends on the speed at
which keys are pressed. Notes are louder when keys are
pressed quickly, and quieter when keys are pressed slowly.
Keeping this in mind as you play a keyboard musical
instrument lets you control note volume without striving to
apply too much pressure with your fingertips.
■ The playability of an acoustic piano
Your Digital Keyboard provides you with key touch that is the
next best thing to an acoustic piano. Note volume changes
automatically in accordance with key press speed.
Use the procedure below to control how much the volume of
played notes change in accordance with playing speed.
