Troubleshooting

If during use any of the following problems should occur,
carefully examine the instrument to see if you can find out
what the problem is, and try resolving it by following the
suggestions below. If the instrument will still not function
properly refer to your dealer.
The instrument will not turn on
• Check that the AC adapter is correctly connected to the
piano and the outlet.
No sound
• Is the speaker cord of the speaker box on the stand con-
nected with the speaker connector on the LP-380 cor-
rectly?
• Make sure that the volume is not set on MIN. If it is,
bring it up to an adequate level.
• Make sure that the MIDI Local function is not set on
OFF. If it is, set it to ON (or turn the instrument off and
then on again).
• Make sure there is not a jack plugged into one of the
Headphones jacks. This would turn the internal speak-
ers off. if so, unplug the jack.
Notes are interrupted
• You have exceeded the maximum polyphony. see
"About maximum polyphony."
The pitch or tone of the piano sounds wrong in some
key regions
• The LP-380's piano sounds replicate the sound of an
actual piano as faithfully as possible. This means that
in some regions of the keyboard, you may feel that
the overtones seem stronger, or that the tone or pitch
seems wrong. This is not a malfunction.
The connected MIDI device does not respond to trans-
mitted MIDI data
• Make sure that all MIDI cables are correctly connected.
Make sure that the LP-380 is receiving MIDI data on
the same channel as the MIDI device.
About maximum polyphony
If the number of notes being played simultaneously ex-
ceeds the maximum polyphony, some notes will be lost
since the LP-380 is equipped with a mechanism that stops
the first note being played to give priority to notes played
with keys pressed later. Some LP-380 sounds, although
they may be a single sound, are generated by two or more
oscillators (one note of a sound-generating circuit). Sounds
using just one oscillator, such as those in banks 1 and 2 of
VIBES/GUITAR, have a maximum polyphony of 120 notes.
Sounds using two oscillators, such as those in banks 1 and
2 of PIANO2 and in banks 1 and 3 of E.PIANO2, have a
maximum polyphony of 60 notes.
120 ÷ Number of sound oscillators = Maximum polyphony
Keep the maximum polyphony in mind and carefully
choose sounds when using Layer mode to play two sounds
simultaneously or when using the damper pedal.
