Main features
30 different high-quality sounds
Thirty richly expressive high-quality sounds are built in, including a stereo concert
grand. In addition to playing one sound at a time, the LP-350 will allow you to layer
two sounds together.
Effects
The LP-350 provides both Reverb, which simulates the natural ambience of a con-
cert hall; and Chorus, which adds richness and motion to the sound.
Pedal simulation
As on an acoustic piano, the LP-350 has three pedals that control the damper, soste-
nuto and soft effects. The damper pedal and soft pedal will respond to half-pedal-
ing, allowing you to vary the depth of the effect by the degree to which you press
the pedal.
Pedal unit
The position of the pedal unit can be adjusted to accommodate any player
or performing style.
Metronome
The built-in metronome lets you adjust the time signature, tempo, and volume; a
bell sound is available for the accent.
Touch control
You can choose from three different “touch-curves” to determine how the sound
will respond to the dynamics of your keyboard playing.
Temperament
In addition to equal temperament, you can select two types of historical tempera-
ment (Kirnberger and Werckmeister) for authentic performances of historical music.
When an acoustic piano sound is selected, the stretched tuning used on pianos is
automatically selected.
Adjustable pitch
You can use the transpose function to transpose the LP-350 into any musical key,
and use the pitch control to make fine adjustments to the pitch.
MIDI connectivity
The LP-350 is equipped with MIDI, the standard way to exchange performance data
between electronic musical instruments and computers. MIDI allows connected
devices to control each other, and also allows the LP-350 to be used as a sixteen-part
multi-timbral sound module.
Robust sound system
The internal sound system features two 10 cm speakers driven by a two 11W amps,
beautifully reproducing the rich sounds and distintive resonance of the instrument.
Dual headphone jacks
Two headphone jacks are provided, allowing two people to listen simultaneously -
parent and child, student and teacher, etc.

0 position, and move it gradually toward the right to increase the volume
gradually.
Connecting the line out jack
If you want to connect amplified speakers (other than the LP-350’s own built-in
speakers), or to a PA system or recording setup, connect the line out jack to the input
jack of your equipment.
The line out jack is a stereo mini (1/8") connector. Use a commercially available
cable of the appropriate type for the equipment you’re using.
Turn off the power of the LP-350 and your other equipment before making
connections. Making connections while the power is on may damage the
LP-350 or the connected equipment or cause malfunctions.

Pitch control
Here’s how to make fine adjustments to the pitch.
If you’re performing together with other instruments and there’s a slight difference
in pitch between instruments, you can adjust the pitch of the LP-350 in 0.5 Hz steps
over a range of 12.5 Hz (427.5 Hz–452.5 Hz). The standard pitch is A=440 Hz.
When you turn off the power, this will revert to the standard setting (A=
440 Hz).
1. Hold down the TRANSPOSE/FUNCTION button and press the B5 or C6 key.
2. The pitch will go down by 0.5 Hz each time you press the B5 key, and go up by
0.5 Hz each time you press the C6 key.

Selecting a temperament
Many compositions of classical music were created with a specific historical temper-
ament (tuning method) in mind. In order to reproduce the original beauty of these
compositions, the LP-350 lets you choose from three temperaments: Kirnberger,
Werckmeister, and the equal temperament most widely used for keyboard instru-
ments used today.
1. Hold down the TOUCH button and press the [HARPSI/CLAV] or [VIBES/
GUITAR] sound select button.
The indicator above the button you selected will light.
Sound button
Temperament
Werckmeister: This is the Werckmeister III scale, cre-
ated by the German organist and musical theoretician
Andreas Werckmeister.
This temperament was developed during the late
Baroque era to allow relatively flexible modulation
between keys.
[HARPSI/CLAV]
Kirnberger: This is the Kirnberger III scale, created by
Johann Phillip Kirnberger in the early 18th century.
It is used mainly for tuning harpsichords.
[VIBES/GUITAR]
Equal temperament: Nearly all of today’s keyboard
instruments use equal temperament. It places the notes
of the chromatic scale at equal intervals, allowing the
same scale to be played in every key.
Both [HARPSI/CLAV] and
[VIBES/GUITAR] indica-
tors unlit
2. To return to equal temperament, hold down the TOUCH button and press the
[HARPSI/CLAV] or [VIBES/GUITAR] sound select button whose indicator is
lit.
You can check the currently selected temperament by holding down the TOUCH
button and noting which sound select button indicator is lit.
When you turn off the power, the temperament will revert to equal tem-
perament.
23
About stretched tuning
The [PIANO 1/L] and [PIANO 2/M] sounds use stretched tuning. In order to obtain
a more natural sound, stretched tuning tunes the lower notes slightly flatter and the
higher notes slightly sharper than the equal tempered pitches. Acoustic pianos are
normally tuned using stretched tuning.

MIDI
What’s MIDI?
MIDI (Musical Instrument Digital Interface) is a world-wide standard for transfer-
ring performance-related information between electronic musical instruments and
computers.
What can you do using MIDI?
By using MIDI, you can control another MIDI device from the LP-350 or play the
LP-350’s sound generator from another MIDI device. You can also use the LP-350 in
conjunction with a sequencer or multiple MIDI devices to enjoy complex ensembles.
MIDI connections
MIDI cables (sold separately) are used to transfer MIDI data. Connect the cable
between the LP-350’s MIDI connector and the MIDI connector of your external
MIDI device. There are two types of MIDI connector.
MIDI sound module
LP-350 rear
MIDI keyboard
MIDI OUT: This transmits MIDI data. The MIDI messages transmitted when you
play the LP-350’s keyboard can play or control an external MIDI
device.
Connect a MIDI cable from the LP-350’s MIDI OUT connector to your
external MIDI device’s MIDI IN connector.
MIDI IN:
This receives MIDI data. MIDI messages transmitted from an external
MIDI device (e.g., MIDI keyboard or sequencer) can control or play
the LP-350’s sound generator.
Connect a MIDI cable from the LP-350’s MIDI IN connector to your
external MIDI device’s MIDI OUT connector.
25
Basic MIDI settings
When you turn on the power, the LP-350’s MIDI parameters are set as follows.
Parameter

Receive channel
Local On
Setting

Receive all (1-16)*
Omni Off
ꢁ
* The metronome sound (D5 , E5) is assigned to be received on channel 10. For this reason,
channel 10 will not receive program change messages.
Changing the transmit channel
MIDI has sixteen channels (1–16) on which data can be transmitted and received.
When you turn on the power, the transmit channel is automatically set to 1. If you
want to change the transmit channel, hold down the TRANSPOSE/FUNCTION
ꢁ
button and press one of the keys C2–D 3 to which the desired channel is assigned.

If you’re in Layer mode, selecting the transmit channel will specify the channel
whose MIDI program change number (PC#) is lower. The transmit channel of the
higher PC# will automatically be set to the next-numbered channel. For example if
you assign MIDI channel 7 for the sound whose MIDI program change number
(PC#) is lower, MIDI channel 8 will automatically be selected for the sound whose
PC# is higher. If you assign MIDI channel 16 to the sound whose PC# is lower, MIDI
channel 1 will automatically be selected for the sound whose PC# is higher.
26
Using the LP-350 as a multi-timbral sound module
By using an external MIDI device to control the LP-350’s internal sound generator,
you can use the LP-350 as a 16-part multi-timbral sound module.
1. Use a MIDI cable to connect the LP-350’s MIDI IN connector to the MIDI
OUT connector of your sequencer or other MIDI device.
2. Transmit MIDI data from the connected sequencer or MIDI device.
For details on how to transmit data from the connected sequencer, refer to its
owner’s manual.
If the LP-350 receives program change messages along with the performance data, it
will play the notes using the internal sound that corresponds to that program num-
ber. However, the project change setting must be enabled for this to happen.
Local on/off
With the Local On setting, playing the LP-350’s keyboard will make the internal
sound generator produce sound and will also transmit MIDI data. With the Local
Off setting, playing the LP-350’s keyboard will not make the internal sound genera-
tor produce sound; only MIDI data will be transmitted. Normally you’ll leave this
setting at Local On.
You can use the Local Off setting if you’re using the LP-350 as a master keyboard,
for example to play sounds on MIDI equipment (a keyboard or sound module etc.)
that’s connected to the LP-350. The LP-350 will not produce sound, but your perfor-
mance will be sounded by the connected MIDI device.
You can also use the Local Off setting if you’re using the LP-350 as a sound module
(for example when the LP-350 is connected to a computer), so that the LP-350 will
not sound each note in duplicate; once when you play its keyboard and a second
time in response to the data echoed-back (retransmitted) from the computer.
To switch between the Local On/Off settings, hold down the TRANSPOSE/FUNC-
TION button and press the [PIANO 1/L] sound select button. Each time you press
it, the Local setting will alternate between On and Off.

When you turn off the power, this setting will revert to Local On.
Program change
You can transmit MIDI program change messages from the LP-350 to switch pro-
grams on a connected MIDI device. The LP-350 will also switch programs when it
receives MIDI program change messages from a connected MIDI device. For the
correspondence between program change numbers and sounds, refer to “program
change” below.)
27
Program change transmission
When you select a sound on the LP-350 using the sound select buttons and BANK
button, a MIDI program change message of the corresponding number 0–29 will be
transmitted.
Program change reception
When the LP-350 receives a program change number 0–29, it will switch to the cor-
responding sound.

MIDI data dump
The LP-350 can transmit its sound settings and effect settings to an external MIDI
data filer (storage device) for saving. When desired, you can load this data back into
the LP-350 to reproduce the saved settings.
Carefully read the owner’s manual for your data filer, and be sure not to
delete important data that you want to keep.
Do not touch the LP-350’s keyboard or buttons while a data dump is being
executed.
29
The following table shows the data that will be saved by a data dump.
Type

Saving data on your data filer
1. Use a MIDI cable to connect the LP-350’s MIDI OUT connector to your data
filer’s MIDI IN connector.
2. Operate your data filer so that it is waiting to receive MIDI data from the LP-
350.
3. On the LP-350, hold down the TRANSPOSE/FUNCTION button and press
the [VIBES/GUITAR] sound select button.
The indicators above each button will blink; the LP-350 is waiting to transmit a
data dump.
If you decide to cancel the data dump, press the TRANSPOSE/FUNCTION but-
ton or the [VIBES/GUITAR] sound select button.
4. Press the TOUCH button.
The data dump will begin, and the data will be transmitted to your data filer.
When transmission is finished, the data will be stored on your data filer and the
LP-350 will return to the normal state in which it can be played.
The LP-350 will not produce sound while waiting to transmit a data dump, or
while transmitting data to a data filer.
Loading data from your data filer
1. Use a MIDI cable to connect your data filer’s MIDI OUT connector to the LP-
350’s MIDI IN connector.
2. On the LP-350, hold down the TRANSPOSE/FUNCTION button and press
the [VIBES/GUITAR] sound select button.

Troubleshooting
If you experience a problem, please check these points first. If the LP-350 still does
not operate correctly, contact a Korg service center.
Problem
Action
Make sure that the AC adapter is correctly connected to
the LP-350 and to an AC outlet.
Power does not turn on.
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.
No sound.
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.
Notes are interrupted.
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.
Something is wrong with the

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.
31
Keep the maximum polyphony in mind and choose your sounds carefully when
using Layer mode to play two sounds simultaneously, or when using the damper
pedal or applying effects.
You can use the following equation to calculate the maximum polyphony when
using different combinations of sounds and effects.
(60 – polyphony used by effects)
usable polyphony
÷
number of sound oscillator = maximum
Example 1:[PIANO 1/L] bank 1 (Grand Piano) is selected and reverb is on
(60 – 10) 2 = 25 (maximum usable polyphony is 25)
Example 2:[HARPSI/CLAV] bank 2 (Clavi) is selected and chorus is on
(60 – 3) 1 = 57 (maximum usable polyphony is 57)
÷
÷
Since the LP-350 is designed to turn off the oldest sounding notes and give priority
to newly played notes, currently-sounding notes will be interrupted when you
exceed the maximum polyphony.

rest on the AC adapter cable or pedal cable.
For greater safety, we recommend that you always attach the anti-tipping
blocks to the rear of the left and right side panels.
Check following assembly
• Are any parts left over?
If any parts are left over, carefully review the assembly procedure to see
where those parts should have been used.
• Make sure that all screws are tight.
37
Other cautions
Please check the following points after assembly.
• Loosened screws
The screws may loosen as time passes after assembly. You should periodically
check whether any screws have become loose. If you feel that the stand
vibrates excessively, it is possible that screws have come loose. If so, re-
tighten them.
• When moving the digital piano to another location
Remove the keyboard unit from the stand, and transport the keyboard unit
and stand separately. Afterward, reassemble them as described in “Assem-
bling the stand.”
• Disassembly
If you need to disassemble the stand, do so by reversing the steps of the
assembly procedure. After disassembly, keep the screws and other parts in a
safe place so that they are not lost.
