Auto Harmony
This sophisticated feature automatically adds appropriate harmony notes to a melody you play on the keyboard.
You can choose from 5 different types of harmony.
T To select an Auto Harmony type:
1- Press the AUTO HARMONY + or - button.
The first time the AUTO HARMONY + or - button is pressed the letter
“H” together with the current Harmony type number will appear on the
MULTI DISPLAY and remain for approximately 2 seconds afterwards.
2. Choose one of the five Harmony types from the list next to the
HARMONY + and - buttons.
3. While the current Harmony type is still showing on the display,
press the AUTO HARMONY + or - button to increase or
decrease the Harmony type number.
Holding down either button increases or decreases the Harmony type
number continuously.
Only a single note can be played at a time on the keyboard
(or the right-hand section of the keyboard when in the Split
mode) when the Auto Harmony feature is used.
In the Single Finger, Fingered, or Split mode, the left-hand
chords determine the harmony notes that will be applied to
the right-hand melody. Also Auto Harmony is not applied to
the left-hand voice in the Split mode and to the Accompani­
ment sounds.
If Auto Harmony is used at the same time as the Dual Voice
feature (see page 10), harmony will not be applied to the
second ‘dual” voice.
The default Auto Harmony type (00: OFF) can be recalled
at any time by pressing both the AUTO HARMONY + and -
buttons at the same time.

Sustain
Sustain causes notes played on the keyboard to fade gradually after you lift your fingers from the keys.
T To turn Sustain on:
Press the SUSTAIN button once (the indicator will light).
Press the SUSTAIN button a second time (the indicator light will go out)
to turn the sustain effect off.
T To turn Sustain on independently for the left and
right-hand voices in the Split mode:
1. Press a key to the right of the Split Point to select the right-
hand voice, then turn Sustain on or off for that voice.
2. Press a key to the left of the Split Point to select the left-hand
voice, then turn Sustain on or off for that voice.
□ When the Dual Voice function is used, sustain is applied to both voices:
□ A sustain pedal can be used as well to achieve the same effect. See “Con­
necting a Foot Pedal” on page 6.
□ Sustain cannot be applied to some of the voices.
