Note: You cannot tune the keyboard
while a prerecorded tune is displayed or
playing.
Follow these steps to tune the keyboard.
1. Repeatedly press
TRANSPOSE/
TUNE/MIDI
until the display shows
Tune
and the current pitch setting.
Note: The number on the display is
the number of “cents” to which the
keyboard is currently tuned, com-
pared to its default pitch. A cent is
the measurement that represents
the acoustical interval between two
tones. 1200 cents equal 1 octave.
You can tune the keyboard to within
50 cents (101 levels) of its default
pitch.
2. Within 5 seconds, repeatedly press
or
+
to lower or raise the key-
board’s pitch. Each time you press
the key, the number on the display
decreases or increases by 1 (cent).
Notes:
You can use the number keypad to
raise the pitch by entering the cent
change value.
• The keyboard automatically resets
the tuning pitch to the default value
of 00 (cents) each time you turn off
the keyboard or play the pre-
recorded tunes.
USING TOUCH RESPONSE
The MD-1150 has a touch response fea-
ture that lets you adjust the volume of
your music’s tone based on how hard
you strike the key(s), so you can add
emotion to your music.
If you want to turn off this feature, press
TOUCH RESPONSE
so its indicator dis-
appears.
To turn on touch response again, press
TOUCH RESPONSE
so its indicator ap-
pears.
Notes:
The touch response setting does not
affect auto accompaniment or
received MIDI data.
The MIDI data sent out from the
MD-1150 is affected by the touch
response setting.
USING A SUSTAIN PEDAL
For added flexibility and control as you
make music, you can connect an option-
al sustain pedal (not supplied), available
through your local RadioShack store. A
sustain pedal lets you sustain the key-
board’s sound.
To connect a sustain pedal to your MD-
1150, insert the plug on the pedal’s cord
into the
SUSTAIN
jack on the back of the
keyboard.
