Introduction

Main features

Wide range of sounds. Thirty different and expressive high-quality sounds, including a Stereo Concert Grand Piano. You can use the Layer function to simultaneously play two sounds.

Effects. The C-320 provides built-in digital effects that can simulate the natural ambience of a concert hall (Reverb) and add richness to the sound (Chorus).

Pedal effects. The C-320 provides the same three pedals as a grand piano, controlling the soft, sostenuto, and damper functions respectively. The damper pedal simulates the natural string resonances of an acoustic piano. Both the damper pedal and the soft pedal let you vary the amount of the effect by how far you press down on the pedal ("half-pedal" function).

Metronome. The built-in metronome allows you to select the time signature, tempo, and volume, and even use a bell sound as the accent.

Touch control. You can choose from three different settings to adjust how the sound will respond to your keyboard playing dynamics.

Temperaments. In addition to the Equal temperament, the C-320 allows you to select two alternative classical temperaments (Kirnberger and Werckmeister) for historically accurate performance of classical music. When selecting an acoustic piano sound, the typical Stretched Tuning is automatically selected.

Adjustable pitch. The Transpose function lets you change the pitch of the piano, and the Pitch Control function allows you to make fine tune adjustments.

MIDI capabilities. The C-320 supports the MIDI protocol, the standard that allows music data to be transferred between musical instruments and computers. MIDI

allows two or more devices to control or be controlled by each other, and also allows you to use the C-320 as a 16-part multitimbral tone generator.

Powerful integrated amplification. C-320 includes a powerful, 25 Watt amplifier, with two 13cm speakers.

Two sets of headphones. You can connect two stereo headphones, to play with your teacher or another musician.

3 To turn the reverb or chorus off, press the REVERB or CHORUS button. The indicator on the button will turn off.

Using the pedals

The C-320 has three pedals: soft, sostenuto, and damper. You can use these pedals to add expression to your playing, as on a traditional piano.

Soft pedal. Pressing this pedal will make the tone softer. You can control the softness of the tone by how far down you press the on pedal ("half-pedaling").

Sostenuto pedal. Pressing this pedal will apply the damper effect only to the notes that are already being held down on the keyboard, and will sustain only those notes. The damper effect will not be applied to any additional notes that you play while holding down the Sostenuto pedal.

Damper pedal. Pressing this pedal will sustain the sound, producing a richly resonant decay. You can control the damper depth by how far down you press the on pedal ("half-pedaling").

Pedal settings for the Layer mode

You can select which sound(s) will be affected by the damper pedal when using the Layer mode.

Note: When the instrument is turned on, the pedal settings are reset. To save these settings, save them using the Data Dump function (see “MIDI Data Dump” on page 32).

1 Hold the TRANSPOSE/FUNCTION button, and press the damper pedal. Each time you press the pedal, the indicator on the sound selection button(s) where the damper pedal is active will light.
2 When the pedal is assigned to the desired sound(s), release the TRANSPOSE/FUNCTION button.

The metronome

The C-320 incorporates a metronome, with which you can set the tempo during practice.

Starting and stopping the metronome. Press the METRONOME button to make the metronome start or stop. When turning on, the metronome is set according to the knob position, but you can adjust it with the procedure described below. After having listened to the demo, the tempo will be that of the last demo that had been listened to.

Adjusting the metronome volume. While the metronome is playing, keep the METRONOME button pressed and repeatedly press the STRINGS/PAD button (or the B5 key) to lower the volume, or the CHOIR button (or the C6 key) to raise it. To reset the volume, simultaneously press the STRINGS/PAD and CHOIR buttons (or the B5 and C6 keys on the keyboard) while holding the METRONOME button.

Key	Effect	Key	Effect
B5	Lower volume	C6	Higher volume

Adjusting the tempo using the TEMPO knob. Use the TEMPO knob to adjust the tempo. The range is = 40 200 .

Numeric tempo input. In some cases, you may require an exact tempo (like 127 BPM). It is possible to enter a precise tempo, using the numeric input.

1 Hold down the METRONOME button.
2 Use the keyboard to input the three-digit tempo value (insert a "0" before a two-number value).

Key	Number	Key	Number
C5	0	C#5	1

Other functions

Touch settings

The keyboard sensitivity, or touch, can be programmed. Keep the TOUCH button pressed, and press the appropriate button to select one of the available touch settings.

Button	Touch sensitivity
PIANO 1/L	Light. Loud notes can be produced even by playing lightly.
PIANO 2/M	Normal. Normal piano touch.
E.PIANO 1/H	Heavy. Loud notes can be pro- duced only by playing very hard.

To check the currently selected setting, hold down the TOUCH button, and look at which of the indicators is turned on.

Note: When the instrument is turned on, the touch setting is reset to Normal.

Alternatively, you can use the TRANSPOSE/FUNCTION button and the keyboard. Hold the TRANSPOSE/FUNCTION button, and press the key on keyboard that corresponds to the touch setting you wish to carry out (see table).

Key	Touch sensitivity
B3	Light. Loud notes can be produced even by playing lightly.
C4	Normal. Normal piano touch.
D4	Heavy. Loud notes can be produced only by playing very hard.

Transpose

In some cases, a song may be written in a difficult key (e.g., many black keys), or you may wish to shift the pitch to match another instrument or vocalist. In such cases, you can transpose (shift the pitch) so that you can use an easier fingering, or use the same familiar fingering to play at a different pitch. This is called the Transpose function.

For example if you transpose upward by one semitone, playing the notes shown at the lower left will produce the pitches shown at the right.

Note: When the instrument is turned on, the transposing is reset.

1 Hold the TRANSPOSE/FUNCTION button, and press the key on keyboard that corresponds to the transpose you wish to carry out (see table). The TRANSPOSE/FUNCTION indicator will remain lit up, to indicate that the transpose function is active.

Key	Effect
F#6 — B6	6 — 1 semitones below
C7	Standard pitch
C#7 — F7	1 — 5 semitones higher

2 To get back to standard pitch, hold the TRANSPOSE/FUNCTION button and press the C7 key. The TRANSPOSE/FUNCTION indicator will turn off.

Fine tuning

In order to adapt the C-320 pitch to that of another instrument, you can adjust the pitch in steps of 0.5Hz over a range of A4 = 427.5 452.5Hz . The standard tuning is A4 = 440Hz .

Note: The pitch will go back to standard level (A4 = 440 Hz) when the instrument is turned off, then on again.

1 Hold the TRANSPOSE/FUNCTION button, and press the corresponding key to change the pitch. Each time the B5 or C6 key is pressed, the pitch will be raised or lowered by 0.5Hz .
2 To get back to standard pitch, hold the TRANSPOSE/FUNCTION button and press the B5 and C6 buttons at the same time.

Key	Fine tuning
B5	Lowers the pitch by 0.5 Hz
B5+C6	Standard pitch (A4 = 440 Hz)
C6	Raises the pitch by 0.5 Hz

Selecting a temperament

There are numerous classical compositions that were composed using temperaments that differ from the "equal temperament" commonly used today. In order to reproduce the original sound of such compositions, the C-320 provides Kirnberger and Werckmeister classical temperaments, in addition to the equal temperament, allowing you to select from a total of three temperaments.

To select one of the available temperaments, hold down the TOUCH button, then press the button corresponding to the desired temperament. To return to the equal tuning hold down the TOUCH button, then press the sound selection button whose indicator is lit.

Button	Temperament
Both indicators turned off	Equal temperament. Nearly all keyboard instruments today use equal temperament. This temperament spaces all semitones at equal distances, and allows identical scales to be played in any key.
HARPSI/CLAV	Werckmeister. This is the Werckmeister III scale invented by Andreas Werckmeister, the German organist and music theoretician. This scale was created in the later Baroque period to allow relatively free transposition.
VIBES/GUITAR	Kirnberger. This is the Kirnberger III scale invented by Johann Phillip Kirnberger in the early 18th century, and is used mainly for tuning harpsi-chords.

To check the currently selected temperament, hold down the TOUCH button, and look at which of the indicators is turned on.

Note: When the power is turned on, the equal temperament will be automatically selected.

About stretched tuning. In order to produce the most natural resonance, PIANO 1 and PIANO 2 sounds use a "stretched tuning" that makes the notes of the lower range slightly flatter than equal temperament, and the upper range slightly sharper. This is how an acoustic piano is normally tuned by professional tuners.

MIDI

What is MIDI?

MIDI, is the abbreviation of Musical Instrument Digital Interface. It is an international standard that was created to connect and transfer data between electronic musical instruments, computers and other devices.

What can you do with MIDI?

Thanks to MIDI, you can use the C-320 to control other instruments, use other instruments to control the C-320, and use a sequencer to create complex musical pieces.

When you use the C-320 keyboard or pedal, or select a sound, the notes, pedal activation and change in sound are transmitted to another instrument, or are recorded by a sequencer.

Connections

Always connect the MIDI OUT connector of the instrument to the MIDI IN connector of another instrument. Never connect two connectors of the same instrument to each other.

Connect the MIDI OUT connector of the transmitting (master) device to the MIDI IN connector of the receiving (slave) device.

To connect the C-320 to a computer, you need a MIDI interface for the computer, sequencing or musical notation software, and two standard MIDI cables. Connect

the C-320 MIDI OUT connector to the MIDI IN connector of the computer. Connect the C-320 MIDI IN connector to the MIDI OUT connector of the computer.

Standard MIDI settings

When turning the instrument on, the MIDI parameters of the C-320 are programmed as follows:

Parameter	Setting
Transmission channel	1
Reception channel(s)	All 16 (1-16)*
Local	ON
Omni	OFF

(*) On channel 10, only metronome notes are received (D#5, E5).

Selecting the transmission channel

The standard MIDI has 16 separate channels available for transmission and reception of data. C-320 always receives on all 16 channels, and transmits on a single channel. To transmit data from the C-320, you need to choose which of the 16 channels you wish to transmit data on.

Hold down the TRANSPOSE/FUNCTION button, and press the note in the range C2-D#3 corresponding to the desired MIDI channel.

Key	Channel	Key	Channel
C2	1	C#2	2
D2	3	D#2	4
E2	5	F2	6
F#2	7	G2	8
G#2	9	A2	10
A#2	11	B2	12
C3	13	C#3	14
D3	15	D#3	16

Note: When the power is turned on, channel 1 will automatically be selected.

Note: By default, channel 10 will automatically be assigned to the metronome sound (notes D#5-E5).

Note: In Layer mode, the second sound transmits on the following channel. For example, if you select channel 7, the first sound will transmit on channel 7, while the second sound will transmit on channel 8. If you select channel 16, the first sound will transmit on channel 16, while the second sound will transmit on channel 1 (cycling back to the first channel).

Using the C-320 as a multitimbral tone generator

When C-320 is controlled from an external MIDI device, it can work as a 16-part multitimbral tone generator. You can select a different sound on each of the 16 MIDI channels.

1 Use a MIDI cable to connect the C-320's MIDI IN to the MIDI OUT of a sequencer etc.
2 Transmit MIDI data from the connected sequencer (or other device). See "Program Change" on page 29 for instructions on how to select a sound using the MIDI Program Change message. Program Change reception must be activated on the C-320 (it is by default).

Read the other devices user's manual for details on sending Program Change messages.

Local On/Off

Local is the parameter that allows you to establish whether the keyboard has to play the internal sounds and transmit MIDI data at the same time (Local On), or whether it just has to transmit MIDI data and not play the internal sound (Local Off).

Local Off should be chosen when you wish to use the C-320 as a mute keyboard, to play another instrument. It should be chosen also when C-320 is connected to a sequencer via its MIDI IN and MIDI OUT connectors. This will avoid the notes to be played twice, by the keyboard and by the sequencer, producing an annoying "echo" effect.

Normally, you will choose Local On (automatically selected when turning the C-320 on), so that playing the keyboard will produce sound.

Hold down the TRANSPOSE/FUNCTION button, and press the PIANO 1 sound selection button. The Local setting will alternate to On/Off each time you press this button.

Local status	PIANO 1 indicator status
Local On	Lit
Local Off	Dark

Note: When the power is turned on, the Local will be automatically set to On.

Program Change

The sound of the C-320 can be selected via MIDI, by sending a Program Change message on the channel where you wish to assign the sound. The table enlists the Program Change numbers (numbering from 0-29; if the transmitting device uses numbers from 1-30, you will need to increment the number by one).

Transmitting Program Change messages. You can send a MIDI Program Change message to a MIDI device connected to the C-320 MIDI OUT, to change its sound. When selecting one of the internal sounds of the C-320 by using the sound selection buttons, a MIDI Program Change number will be transmitted, as shown in the table below.

Receiving Program Change messages. When a Program Change message is received from an external device, the corresponding internal sound will be selected

on the C-320, as shown in the following table. Only Program Change (PC) numbers in the range 0–29 have effect on the C-320, while other numbers (30-127) are ignored.

MIDI Data Dump

You can save the current sound settings (Single or Layer mode) on an external MIDI storage device, like a sequencer or a MIDI data file. You can later reload these data into the C-320, to restore a saved set of data.

Warning: To avoid loosing data, carefully read the owner's manual of your MIDI data file. Loading data into the memory of the C-320 will erase all existing data.

Hint: To avoid any trouble, don't forget to deactivate System Exclusive data reception on the connected device.

The following table shows which data are saved with the Data Dump.

Category	Data
Single mode	Reverb and chorus settings (on/off status, send level)
Layer mode	Balance between sounds, damper pedal on/off status for each sound.

Saving data to the data filer. Here is how to save the data of the C-320.

1 Use a MIDI cable to connect the C-320 MIDI OUT to the MIDI IN of the data file.
2 Prepare the data file to receive MIDI data.
3 On the C-320, hold down the TRANSPOSE/FUNCTION button, and press the VIBES/GUITAR sound selection button. The indicators of the TRANSPOSE/FUNCTION and VIBES/GUITAR buttons will blink, indicating that the C-320 is ready to transmit the data dump.
4 Press the TOUCH button. The data dump will begin, and the sound setting data will be transmitted to the data filer.

During a data dump operation, the C-320 will not produce sound, and no other function will work. When the data dump is completed, you will return to normal playing condition.

You may cancel a data dump operation before the data dump begins, by pressing the TRANSPOSE/FUNCTION or VIBES/GUITAR button.

Loading data from the data filer. You can load into the C-320 data you previously saved on a data filer.

1 Use a MIDI cable to connect the MIDI IN of the C-320 to the MIDI OUT of the data filer.

2 On the C-320, hold down the TRANSPOSE/FUNCTION button and press the VIBES/GUITAR sound selection button. The indicators of the TRANSPOSE/FUNCTION and VIBES/GUITAR buttons will blink, and the C-320 will wait to receive the data dump.
3 Set the data filer to send the sound setting data that were previously saved from the C-320. Please read the data filer owner's manual for details on data transmission.

The C-320 will receive the data.

When the data dump is finished, the C-320 will return to the same status it was before the data dump.

During a data dump operation, the C-320 will not produce sound, and no other function will work.

You may cancel a data dump operation before the data dump begins, by pressing the TRANSPOSE/FUNCTION or VIBES/GUITAR button.

Assembling the stand

Cautions for assembly

• When placing the piano on the stand, be careful not to pinch your hands.
• Be sure that the correct parts are assembled in the correct orientation and position, and follow the steps in order.
• Do not apply weight to the front edge of the piano before tightening the screws, otherwise the piano may fall down.

Assembling procedure

1 Open the packing carton and take out the contents. Check that all of the following items are available.

Sideboard A (Left side)

Pedal Box

Sideboard B (Right side)

Assembly Accessories

Screws (a)

(M6 x 20)...4pes.

Cable holder ...2 pcs.

Screws (b)

(M4 x 14)...6pcs.

Piano Fasteners ...2 pcs.

Caps...4pcs.

Adjuster...1pc.

NB: You will need a cross-point (Phillips #2) screwdriver for assembly.

2 Screw the adjuster into the pedal box as far as it will go, and attach the pedal cable. Use screws (a) to fasten the side panels to the pedal box. Make sure that there is no gap between the side panels and the pedal box.

3 With the finished surface (woodgrain) facing forward, curve (bow) the back panel slightly and fit it into the grooves of the side panel.

4 Use screws (b) to fasten the side panels.

Start by fastening the bottom edge of the back panel (four locations). In two locations, pass the screw through a cable holder to attach it to the stand. Attach the power cable holder at either the right side or the left side depending on the location of the AC outlet you'll be using.

Then fasten the top edge of the back panel (two locations). Don't tighten these screws completely yet, since you'll be adjusting this area after you attach the instrument to the stand.

5 Make sure that the stand is not tilted and that there are no gaps in it, and then firmly tighten all of the screws, except for the two screws you left untightened.

6 Attach the instrument.

Position the screw heads protruding from the inside of the left and right sides of the stand, so that they are aligned with the grooves of the metal fitting at the left and right ends of the instrument, and gently lower the instrument onto the stand. If the instrument is aligned correctly, the screws on the inside of the side panels will fit firmly into the grooves of the metal fittings.

You can perform this step more easily if you use your body to apply pressure to the side panel of the stand while sliding the instrument onto the stand.

Note: Carefully lower the left and right ends of the instrument evenly, keeping the instrument level, and being careful not to pinch your hand or drop the instrument.

Note: The side panels are easily scratched; please use caution.

7 Make sure that there are no uneven gaps between the top surface of the instrument and the top of the side panels.

If you notice any unsightly gap, make adjustments by loosening the screws (a) that fasten the side panel to the pedal box.

If you notice an uneven gap, loosen screws (a) to make adjustments.

If there is a very noticeable gap between the instrument and the side panels of the stand, or if the gap is uneven, it may be that the instrument was not placed correctly on the stand. If so, lift up the entire instrument and place it correctly on the stand.

Note: Lifting only one side is very dangerous and may also damage the metal fixtures of the instrument itself. You must raise or lower both left and right ends of the instrument simultaneously, keeping the instrument level.

8 While pressing the upper edge of the stand, tighten the two back panel screws that you had left untightened.

9 Fasten the instrument fastening bolts from below the instrument.

Then loosen the adjuster, and adjust it so that it is in firm contact with the floor.

Note: Unless the adjuster is in firm contact with the floor, the pedal will wobble, possibly causing malfunctions

Verify that all screws are firmly tightened. Finally, place caps on the heads of pedal box screws (a).

10 Connect the included power cable to the AC adaptor.
11 Connect the pedal cable and the DC plug of the AC adaptor to the bottom of the instrument, and use the cable retainers to fasten the cables.

Note: Pay attention to the orientation of the connector when connecting the pedal cable.

Note: When placing your digital piano, be careful that the stand is not resting on the AC adaptor cable.

Check after assembly

[·] Are any parts left over?
If any parts are left over, check the diagrams to see where they should be used.
[·] Make sure that all screws are tight.

Caution

Caution when transporting the instrument. Remove the piano from its stand, and transport them separately. After transportation, refer to these instructions and reassemble the piano and stand.

Screw loosening. After assembly, the various screws and bolts of the stand may loosen as time goes by, causing the stand to wobble. If this occurs, re-tighten the screws.

Disassembly. If you need to pack up the piano, reverse the assembly order by which the piano was attached to the stand and the stand was assembled. After disassembly, save the screws and other parts so that no parts are lost.

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 or to an Authorized Korg Service Center.

Problem	Possible remedy	Page
The instrument will not turn on.	Check that the AC adapter is correctly connected to the piano and the outlet.	11
No sound.	(1) Make sure that the volume is not set on 0. If it is, bring it up to an adequate level.	13
	(2) Make sure there is not a jack plugged into one of the PHONES connectors. This would turn the internal speakers off. if so, unplug the jack.	12
	(3) 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).	29

Polyphony

The C-320 contains sampled sounds, which have been recorded, analyzed and processed from the actual sounds of the original musical instruments. These sounds usually consist of one or more different samples reproduced by pressing a key. Each sample is played back by a single oscillator. Sounds using just one oscillator have a full polyphony of max. 60 voices, while sounds using two oscillators have a limited polyphony of max. 30 notes. Sounds using more oscillators have a more limited polyphony. When the number of notes exceeds the limit of the sound, some notes will be stopped, so that the new ones can be heard.

Furthermore, when playing in Layer mode with more than two notes, the max. polyphony depends on how many oscillators are used in total. Using the REVERB, CHORUS further reduces the polyphony, respectively, by 10 and 3 notes.

Please refer to the table on page 16 for more information about the number of oscillators used by each sound.
