Optimus MD-1200 ユーザーズマニュアル

29

The MD-1200 automatically selects the
key of middle C each time you turn it on.
For added flexibility as you play, the
MD-1200 lets you change (transpose)
the musical key.

Follow these steps to change keys.

1. Repeatedly press 

 until 

 appears

on the display.

Note: The number on the display is
the number of semitones to which
the keyboard is set, compared to its
default key. You can transpose the
key up or down 12 semitones (one
octave).

2. Within 5 seconds, press 

 or 

 to

raise or lower the key. Each time
you press the key, the number on
the display increases or decreases
by 1 (semitone).

• The MD-1200 automatically resets

the key to the default value of 0

(middle C) each time you turn off the
keyboard.

• The transpose setting also affects

memory playback (see “Playing
Back from Memory” on Page 34)
and auto accompaniment.

Although your MD-1200 never goes out
of tune, it does let you adjust its pitch to
match other instruments or musical re-
cordings.

Note: You cannot adjust the keyboard’s
pitch while the demonstration songs are
playing.

1. Repeatedly press 

 until 

 appears.

2. Press   or   so 

 appears.

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
one hundredth of a semitone. You
can tune the keyboard up or down
50 cents (a half semitone).
