Playing the Digital Keyboard
E-7
Using headphones cuts off output from the built-in speakers,
which means you can practice playing even late at night
without disturbing others.
• Be sure to turn down the volume level before connecting
headphones.
• Headphones do not come with the Digital Keyboard.
• Use commercially available headphones. See page E-1 for
information about options.
• Do not listen to very high volume output over
headphones for long period. Doing so creates the risk
of hearing damage.
• If you are using headphones that require an adaptor
plug, make sure you do not leave the adaptor plugged
in when removing the headphones.
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.
