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 ???ne 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

Chapter 5

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 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.

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.

Program change numbers and sounds

28

Enabling/disabling program changes

Enable this setting if you want program change messages to be transmitted and received, or disable it if you don???t want these messages to be transmitted or received.

To enable or disable program changes, hold down the TRANSPOSE/FUNCTION button and press the [PIANO 2/M] sound select button. Each time you do so, the setting will switch between Enabled and Disabled.

When you turn off the power, the setting will revert to Enable.

Control changes

Messages such as operations of the LP-350???s damper pedal can be transmitted to a connected external MIDI device to control it, and these messages can be received from an external MIDI device to control the LP-350.

Enabling/disabling control changes

Enable this setting if you want control change messages to be transmitted and received, or disable it if you don???t want these messages to be transmitted or received.

To enable or disable control changes, hold down the TRANSPOSE/FUNCTION but- ton and press the [E.PIANO 1/H] sound select button. Each time you do so, the set- ting will switch between Enabled and Disabled.

When you turn off the power, the setting will revert to Enable.

MIDI data dump

The LP-350 can transmit its sound settings and effect settings to an external MIDI data ???ler (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 ???ler, 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.

Saving data on your data ???ler

1.Use a MIDI cable to connect the LP-350???s MIDI OUT connector to your data ???ler???s MIDI IN connector.

2.Operate your data ???ler 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 ???ler. When transmission is ???nished, the data will be stored on your data ???ler 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 ???ler.

Loading data from your data ???ler

1.Use a MIDI cable to connect your data ???ler???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.

The indicators above each button will blink; the LP-350 is waiting to receive a data dump.

If you decide to cancel the data dump, press the TRANSPOSE/FUNCTION but- ton or the [VIBES/GUITAR] sound select button.

3.Operate your data ???ler to transmit the previously-saved LP-350 data.

For details on how to transmit data, refer to the owner???s manual of your data ???ler.

The LP-350 will receive the data, and when all data has been received, it will return to the normal state in which it can be played.

The LP-350 will not produce sound while waiting to receive a data dump, or while receiving data to a data ???ler.

Troubleshooting

If you experience a problem, please check these points ???rst. If the LP-350 still does not operate correctly, contact a Korg service center.

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) ??? number of sound oscillator = maximum usable polyphony

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.
