Problem
Possible Cause and Solution
When the PortaTone is turned on or off, a
popping sound is temporarily produced.
This is normal and indicates that the PortaTone is receiving
electrical power.
There is no sound even when the keyboard is
played or when a song is being played back.
Check that nothing is connected to the PHONES/OUTPUT jack on
the rear panel. When a set of headphones is plugged into this
jack, no sound is output.
Make sure that the following settings are appropriate: Main Voice
Volume (#01, page 31), Dual Voice Volume (#11, page 35), and
Split Voice Volume (#21, page 37).
The selected voice does not sound properly, or
is too low in volume.
There is no sound when playing the keyboard.
When setting the Split Point, the keyboard is used only to change
the value and does not produce any sound.
Playing keys in the right hand section of the
keyboard does not produce any sound.
When using the Dictionary type (Chord Guide, page 62), the keys
in the right hand section are used only for entering the chord root
and type.
The sound of the voices or rhythms seems
unusual or strange.
The battery power is too low. Replace the batteries. (See page 8.)
The accompaniment does not play back even
when pressing the START/STOP button.
When External Clock (page 98) is set to “on,” style playback
CANNOT be controlled from the PortaTone panel controls.
There is no sound on either the PortaTone or
the connected MIDI device.
• If Local Control (Function #84, page 97) is set to “off,” the
PortaTone voices will not sound even when playing the keyboard.
• If Keyboard Out (Function #82, page 97) is set to “off,” the
connected MIDI device will not sound when playing the PortaTone
keyboard.
• Make sure that the Accompaniment Volume (page 55) is set to
an appropriate level.
• Make sure that the Accompaniment Split Point (#51, page 59) is
set to an appropriate value.
The accompaniment does not sound properly.
• Make sure that the Send Level parameter for the effect (and the
intended voice: Main, Dual, of Split) is set to an appropriate value.
(See pages 31, 35, 37)
• Make sure that the corresponding effect is turned on. (See pages
40, 41, 42, 43)
• For the Harmony effect, make sure that Harmony Volume (#39,
page 44) is set to an appropriate value.
The Reverb/Chorus/DSP/Harmony cannot be
heard properly.
When playing back one of the Pianist styles
(#91 - #100), the rhythm cannot be heard.
• This is normal. The Pianist styles have no drums or bass — only
piano accompaniment. The accompaniment of the style can only
be heard when accompaniment is set to ON and keys are played in
the auto accompaniment section of the keyboard.
The PortaTone is polyphonic up to a maximum of 32 notes. If the
Dual voice or Split voice mode is being used and a style or song is
playing back at the same time, some notes/sounds may be
omitted (or “stolen”) from the accompaniment or song. (See the
note on page 108.)
Not all of the voices seem to sound, or the
sound seems to be cut off.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the PortaTone may
produce interference. To prevent this, turn off the mobile phone
or use it further away from the PortaTone.
