About the maximum polyphony

The LP-350's maximum polyphony is 60 notes, but this will change depending on
the number of oscillators (individual notes in the sound generation circuitry) used
by the selected sound, and on the effects you're using.
If you're not using effects, and you select a sound such as [HARPSI/CLAVI] that
consists of a single oscillator, the maximum polyphony will be 60 notes. However if
you select a sound such as [PIANO 1/L] that consists of two oscillator, the maxi-
mum polyphony will be 30 notes. The number of oscillators used by each sound is
shown in the table "Selecting a sound (Single mode)" on page 15 .
If you're using effects, the polyphony will decrease by 10 notes when using reverb,
or by 3 notes when using chorus.

Make sure that the AC adapter is correctly connected to
the LP-350 and to an AC outlet.
Make sure that the LP-350's volume is not set at zero. If
it is, raise the volume to an appropriate level.
Make sure that MIDI Local Control is not turned Off. If
Local Control is Off, turn it On.
Make sure that nothing is plugged into a headphone
jack. If something is plugged into a headphone jack,
unplug it.
You're exceeding the maximum polyphony. Refer to the
section "About the maximum polyphony," below.
The piano sounds are designed to reproduce the sound
of an actual piano as faithfully as possible. This may give
you the impression that there is something wrong with
the pitch or tone, such as some overtones appearing to
be louder in certain ranges of the keyboard, but this is
not a malfunction.
Make sure that all MIDI cables are connected correctly.
Make sure that the LP-350 is receiving MIDI data on the
same channel as your other MIDI device.
