Troubleshooting
If you think there’s a problem, read this first.
Case
Cause/Remedy
The power doesn’t
come on
Is the power cord connected and plugged in
correctly? (p. 8)
The button doesn’t
work
Is the panel locked? (p. 35)
Is the Tone locked? (p. 35)
Turn the power off, then back on.
No sound is heard
Is the volume level of the MP-70 turned all the
way down? (p. 9)
Are headphones plugged in and headphones
indicator lights up? (p. 8)
Has a plug remained connected to the Phones jack?
When headphones are connected, the keyboard’s
speaker stops playing.
Is Local Off selected?
When Local Control is set to OFF, no sound is
produced by playing the keyboard. Set Local
Control to “ON” (p. 39).
Is V-LINK switched on?
While V-LINK is switched on, no sound is
produced when you press any of the twelve
keys at the left end of the keyboard (p. 36).
No sound is heard
(when a MIDI in-
strument is con-
nected)
Have all devices been switched on?
Are the MIDI cables connected correctly?
Does the MIDI channel match the connected
instrument? (p. 39)
Sounds are heard
twice (doubled)
when the key-
board is played
Is the MP-70 in Dual play? (p. 19)
When the MP-70 is connected to an external
sequencer, set it to the Local OFF mode (p. 39).
Alternatively, the sequencer could be set so its
MIDI Thru feature is OFF.
The tone has
changed in the
Split or Dual play
If you use Dual play or Split play with a TONE
SELECT button for which tone number 3 is
selected, tone number 1 will be selected for
that TONE SELECT button (p. 14).
Some tones assign the tone that had been selected
before you pressed the [SPLIT] button to the left
hand area of the keyboard. Please refer to “Tone
List” (p. 42).
Tone doesn’t
change
Is the panel locked? (p. 35)
Is the Tone locked? (p. 35)
Turn the power off, then back on.
Are the indicators for the [SPLIT] and [TWIN
PIANO] buttons flashing?
Setting of functions is in progress. Press the
[SPLIT] or [TWIN PIANO] button to exit
function mode (p. 32).
Not all played
notes are sounded
The maximum number of notes that the MP-70
can play simultaneously is 64.
Frequent use of the damper pedal when playing
along with a song may result in performance
data with too many notes, causing some notes
to drop out.
The tuning or pitch
of the keyboard or
song is off
Have you set Transpose? (p. 17)
Are the settings for the “Temperament” and
“Stretch Tuning” correct? (p. 34)
Is the setting for the “Master Tuning” correct?
(p. 33)
Song doesn’t play
back/ Only the
sound of a particu-
lar instrument in a
song does not play
Are the indicator for the Track buttons ([LEFT]
and [RIGHT] buttons) extinguished? (p. 24)
If the button indicator is out, the music on that
track is not heard. Press the track button so the
indicator is illuminated.
Can’t record
Has one of the track buttons for recording
been selected? (p. 25–p. 28)
Tempo of record-
ed song or metro-
nome is off
If you select an internal song in which the tempo
changes during the song, and then record, the
tempo will change in the same way for the
performances. The tempo of the metronome will
also change in the same way.
If you record additional material without
erasing the previously recorded song, the
song will be recorded at the first-recorded
tempo. Please erase the previously recorded
song before you re-record (p. 30).
The recorded per-
formance has dis-
appeared
Any performance that has been recorded is
deleted when the power to the MP-70 is
turned off. A performance cannot be restored
once it’s been deleted.
If you do not want a performance to be
deleted, use Song Backup (p. 31).
Depressing a ped-
al has no effect, or
the pedal effect
doesn’t stop
Is the pedal connected correctly?
Make sure the pedal cord extending from the
stand is securely connected to the pedal jack
on the rear of the unit (p. 8).
The pedal rattles
Adjust the adjuster underneath the pedal so
that the pedal presses firmly against the floor
surface (p. 10).
Reverberation still
audible even with
Reverb turned off
Since the MP-70’s piano sounds faithfully repro-
duce the sense of spaciousness and reverberation
of an actual acoustic piano’s sound, a certain
amount of reverberation is still perceptible, even
with the reverb effect deactivated.
