Problem
VOICES/RHYTHMS
The volume of Upper keyboard is louder than that
of Lower keyboard, or vice versa.
Pedalboard doesn't sound, even when its volume is
properly set.
When keys on the Lower keyboard or pedalboard
are pressed, the sounds of percussion instruments
are also heard.
Even though a Dotted button's rhythm has been
selected and started, the pattern does not sound.
EFFECT
The Initial Touch function does not operate.
The Reverb effect does not operate, even when
Reverb parameters for the selected voice sections
are increased.
The Tremolo effect cannot be heard, even when the
TREMOLO (FAST) button in the DISPLAY
SELECT section is on.
ACCOMPANIMENT
The pitch in the Single Finger mode does not
change, even when pressing different keys of
the keyboard.
While an intro./Ending pattern is automatically
playing, the Lower keyboard does not produce any
sound, even when the keys are played.
The Accompaniment cannot be heard even when
an appropriate Accompaniment type is selected and
the rhythm has been started.
The harmony notes of the Melody On Chord
function cannot be heard.
Possible Cause and Solution
Manual Balance is wrongly set to the either side, Upper or Lower. Open the
Voice Display by pressing the VOICE DISPLAY button in the DISPLAY
SELECT section, and select page 2 to display the Manual Balance. Then
change the balance between Upper keyboard and Lower keyboard.
● One of the A.B.C. modes, Single Finger or Fingered Chord, is active. Set
the A.B.C. mode to off on A.B.C. page.
● The TO LOWER button in the Pedal Voice is turned on. Turn them off.
Keyboard Percussion function is set to on.
Turn the Keyboard Percussion off.
Since the Dotted buttons contain User rhythms, no rhythm will sound if a
Pattern Disk pattern has not been saved to the selected Dotted button.
Initial Touch setting in the Voice Condition is not high enough to get the effect.
Adjust the Initial Touch setting using the Voice Condition display.
The Reverb setting of the targeted voice group is set to 0. Raise the Reverb
volume in the Voice Condition page 2 of the desired voice group.
To get the Tremolo effect, you first need to select the Tremolo function in the
Voice Condition page 3 or Effect Set page.
Single Finger mode will only produce notes when played within a fixed octave
interval on the Lower keyboard.
If notes with the same letter name are pressed outside of that range, the chords
that are sounded will share the same pitch.
Since the Accompaniment chords play automatically one after another, the
Lower keyboard is designed not to produce any sound during the playback of
an Intro./Ending pattern.
The Accompaniment volume is set to 0 as the default. Be sure to raise the
Accompaniment volume on the rhythm condition page.
The Upper keyboard has been set to sound only Lead voices. Raise the volume
of Upper Keyboard voices (not Lead voice, in this case) high enough to get the
effect.
