Check the eect on/o settings. Also check settings such as the
eect levels.

Could the volume have been lowered by a pedal operation,
a D Beam controller operation, or a MIDI message (volume or
expression) received from an external MIDI device?
Step on the pedal, move your hand above the D Beam controller,
and check settings of the other controllers.
p. 47, p. 48
Could the PART [PERC]/[LOWER]/[UPPER]/[SOLO] buttons or

sound?
If the sound of a specic Part or Live Set layer is distorted, lower
the volume for that Part or Live Set layer.
p. 37, p. 58
Could the [VOLUME] knob be set too high? If the overall sound is distorted, lower the [VOLUME] knob. p. 18
Could the Output Gain be raised excessively? Check the system setting “SOUND”. p. 84
Pitch is wrong
Could the JUPITER-80’s tuning be incorrect? Check the system setting “Master Tune”. p. 84
Could the pitch have been changed by a pedal operation or by
a pitch bend message received from an external MIDI device?
Check the pedal and the pitch bender. p. 47, p. 48

Notes are broken o
Notes will be interrupted if more than 256 notes are sounded
simultaneously.

Increase the voice reserve setting for layers in which notes must
not drop out.
p. 58
Notes remain sounding
when you play the
keyboard
Could the polarity of the hold pedal be reversed? Check the system setting “Hold Pedal Polarity”. p. 83
Sound is still heard from
the opposite side as well
even when panned all the
way to one side
Could eects be applied?
Since the JUPITER-80’s internal eects are stereo, applying
an insert eect will allow eect sound to be heard from the
opposite side even if the source sound is panned all the way to
one side.

Notes played in a high
register sound funny
When you play high notes on the JUPITER-80, you might hear
notes that fail to sound, whose pitch fails to rise, or a noise that
changes depending on the note you play (a warbling, chirping,
rustling, beeping, etc.)
This is usually because you have exceeded the highest note
that the JUPITER-80 is able to produce, and won’t occur with
the notes you would normally use. This does not indicate a
malfunction.
—
Changing the tempo does
not aect the arpeggio
tempo or delay time
Could the system setting “USB Song Sync Mode” have been set
to “SLAVE”?
If “Sync Mode” is set to “SLAVE,” change the tempo of the external
device that is transmitting MIDI clock data.
