ACCOMPANIMENT AND OTHER FUNCTIONS
Problem
VOICES/RHYTHMS
Only one sound is heard when two notes of the
Lead or Pedal voices are simultaneously played.
The Pedal voices do not sound, even though the
volume is properly set.
The Touch Tone function does not operate.
While an intro./Ending pattern is automatically
playing, the Lower keyboard does not produce
any sound, even when the keys are played.
Even though a Dotted button’s rhythm has been
selected and started, the pattern does not sound.
During use of the Rhythm Pattern Program, no
sound is produced even when you play a certain
percussion sound.
EFFECTS
The Symphonic, Flanger, and Delay effects
cannot be heard, even when they are set in Effect
Set.
The Tremolo effect cannot be heard, even when
the TREMOLO (FAST) button in the DISPLAY
SELECT section is on.
The Pan function does not operate.
The Reverb effect does not operate, even when
Reverb parameters are increased.
Despite its volume being set to a suitable level,
the Accompaniment cannot be heard.
The pitch in the Single Finger mode does not
change, even when pressing different keys of
the keyboard.
The harmony notes of the Melody On Chord
function cannot be heard.
Possible Cause and Solution
For practical performance reasons, the Electone has been designed so that
one note of the Lead or Pedal voices can be played at a time. If several
keys are pressed at once, only the highest note will be sounded (highest-
note priority).
The Single Finger or Fingered Chord mode of Auto Bass Chord is on.
Turn off the mode in the display. (See page 56.)
Adjust the Touch Tone settings in the Voice Condition display.
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.
Since the Dotted buttons contain User rhythms, no rhythm will sound if a
pattern has not been saved to the selected Dotted button.
If percussion sounds have been recorded to all 16 rhythm tracks, no
subsequently selected instruments can be heard or recorded. If necessary,
erase one of the tracks and play the sound.
Effects must be selected first in the Voice Condition display. (See page
26.)
Tremolo must be selected first in the Voice Condition display (for panel
voices), or in the Flute Voices Volume page (for Flute Voices). (See page
46.)
The Pan function can only be used if all other effects in the Voice Condition
page are set to off. (See page 38.)
Increase the Reverb on the panel Reverb controls, or increase the Reverb
Depth in Reverb Page 1.
The rhythm has not been started. Be sure to use Accompaniment together
with the rhythm.
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.
The Upper keyboard has been set to sound only Lead voices. Increase the
volume of the Upper Keyboard voices.
