Main features
Expressive piano sounds
Dynamic Switching technology selects different sound waveforms in response to variations in your keyboard touch, producing the richly expressive piano sounds that you expect from Korg.
Weighted Hammer Action
The C-6500 features the RH (Real Weighted Hammer Action) keyboard, which varies the resistance of the keyboard in four stages, just as on a grand piano.
Rich array of sounds (p.10)
Choose from eight high-quality sounds developed by Korg, including a superb concert grand piano. There is also an additional Bass sound. You can use the Layer or Split functions to play two sounds at the same time. The stereo sampling tone generator provides a concert grand piano that not only sounds rich, but also reproduces a spacious ambience.
Effects (p.12)
The built-in digital effects provide both Reverb, which can recreate the ambience of a concert hall, and Chorus to add fullness and enhance the stereo imaging of the sound.
Pedal effects (p.12)
The C-6500 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 (p.13)
The built-in metronome provides a steady beat for practice. You can set the time signature, tempo, and volume, and can even select a different sound for the downbeat.
Recorder (p.17)
You can record, overdub and play back your own performance using the built-in recorder. The functions are easier to use than a traditional tape recorder.
Touch control (p.14)
Three touch curves allow you to tailor the keyboard response to your own playing style.
Temperaments (p.16)
In addition to the traditional equal temperament, you can also select one of the two classical temperaments (Kirnberger or Werckmeister) for historically authentic performances.
Adjustable pitch (p.15)
You can use Transpose to transpose the pitch in semitone steps, and Pitch Control to make fine adjustments to the pitch.
MIDI (p.19)
"MIDI" is a world-wide standard that allows performance data to be transferred between electronic musical instruments and computers. Via the C-6500's MIDI connectors, it can control (or be controlled by) another MIDI device, and can even be used as a 16-part multi-timbral tone generator.

When the headphones are plugged in, no sound will be heard from the built-in speakers.
You can use headphones when you do not want to be heard by those around you, such as when practicing at night.
There are two headphone jacks so two people can listen through headphones at the same time, such as student and teacher, etc...


When using headphones, protect your ears by avoiding long periods of use at high volumes.

3. Using the pedals
The C-6500 has three pedals: soft, sostenuto, and damper. You can use these pedals to add expression to your playing, as on a traditional piano.

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").
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.
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").
Pedal settings for the Layer and Split functions
You can select which sound(s) will be affected by the damper pedal when using the Layer and Split functions.
Note
The C-6500 can remember this setting even when the power is turned off.
When using the Layer function, or the Split function with a sound other than bass in the lower range
- Hold down the Transpose/Function switch, and press the damper pedal.


Each time you press the damper pedal, the pedal effect will be applied as shown below. At this time, the sound selector switch(s) will light to indicate which sounds will be affected by the damper pedal.

3. To return to the conventional sound for the accented beat, hold down the Metronome switch and press the Harpsi sound selector switch.
The Harps switch indicator will light.
5. Selecting the Touch Response Curve
The C-6500 offers three touch response curves, so you can select the way in which your keyboard playing strength will affect the loudness of the sound.
When the power is turned on, the Normal touch setting will be selected.
1. Hold down the Touch switch and press either the Piano 1/L, Piano 2/M, or Piano 3/H switch to select the desired touch sensitivity.
If you select the Piano 1/L switch or Piano 3/H switch, the Touch switch indicator will light.

Piano 1/L: Light touch (even light touch can produce loud notes)

line
| Playing strength | Note loudness | | ---------------- | ------------- | | Soft | 0 | | Strong | High |Piano 2/M: Normal touch

line
| Playing strength | Note loudness | | ---------------- | ------------- | | Soft | 0 | | Strong | 1 |Piano 3/H: Heavy touch (heavy touch is necessary to produce loud notes)

line
| Playing strength | Note loudness | | ---------------- | ------------- | | Soft | 0 | | Strong | High |6. Changing the key (Transposing)
The C-6500's Transpose function lets you change the pitch in semitone steps. You can use this function to play a song at the correct pitch but in an easier key (e.g., a key with fewer sharps or flats), or to play a song at a different pitch to match another instrument or vocalist while still using the familiar fingering.
The pitch can be transposed in a range of eleven semitones.
1. Hold down the Transpose/Function switch and press a key in the range of F#6-F7.
If you press a key other than C7, the Transpose/Function switch indicator will light, showing that the pitch has been transposed.
The pitch of the entire keyboard will be shifted so that the key you pressed will produce the C7 pitch.

2. To return to the original (non-transposed) setting, hold down the Transpose/Function switch and press the C7 key.
The C-6500 will also return to the original pitch when the power is turned back on.
To raise the pitch of a song by one semitone
Here's an example where a C# will sound when you play a C key.
- Hold down the Transpose/Function switch and press the C#7 key.
The pitch has been transposed upward by a semitone, and playing the notes shown in the lower left will sound the pitches shown in the lower right.

To play a song in the key of Bb using the fingering of the G-scale
Bb is a minor third (three semitones) above G. So you will need to transpose the C-6500 so that when you play the C7 key, the D#7 pitch (three semitones above C7) will sound.
- Hold down the Transpose/Function switch and press the D#7 key.
7. Making fine adjustments to the pitch
You can make fine adjustments to the pitch.
Use this to correct small differences in pitch when you play together with other instruments, or when playing along with an existing recording.
The pitch can be adjusted in a range of +/-12.5 Hz (427.5 Hz—452.5 Hz).
Note The C-6500 can remember this setting even when the power is turned off.
To raise the pitch
- Hold down the Touch switch and press the Part 2 switch.
The pitch will rise by approximately 0.5 Hz each time you press the switch.

To lower the pitch
- Hold down the Touch switch and press the Part 1 switch.
The pitch will fall by approximately 0.5 Hz each time you press the switch.

To return to the original pitch
- Hold down the Touch switch and press the Part 1 and Part 2 switches simultaneously.
The pitch will return to the original setting (A4=440 Hz).

8. Selecting a temperament
Many classical compositions were originally composed using various temperaments. So that you can reproduce the original sound of these compositions, the C-6500 lets you select two types of historical temperament, Kirnberger and Werckmeister, as well as the Equal Temperament that is used on most keyboard instruments today.
Werckmeister
This is the Werckmeister III temperament created by the German organist and music theorist, Andreas Werckmeister. This temperament was created in the late Baroque era to allow relatively free modulation between keys.
Kirnberger
This is the Kirnberger III temperament created by Johann Philip Kirnberger in the early 18th century. This is used mainly for tuning harpsichords.
Equal temperament
This is the system of tuning used on virtually all keyboard instruments today. Since all semitones are spaced at equal intervals, you can play identical scales in any key.
To change the temperament
- Hold down the Touch switch and press the E.Piano 2 or Harpsi sound selector switch.

To return to equal temperament
- Hold down the Touch switch and press the sound selector switch whose indicator is lit.
The indicator will go dark. You can also return to equal temperament by turning the power off and on again.
Note
Piano 1, Piano 2 and Piano 3 sounds use stretched tuning. This is a method of tuning in which the lower range is tuned slightly flatter and the upper range is tuned slightly sharper than the equal tempered pitches, in order to produce a more natural-sounding resonance.
Recording and playing-back your performance
The built-in recorder of the C-6500 lets you record and play back your performance as easily as when using a tape recorder.
There are two individual parts. You can use the two parts to record two different songs, or to separately record two parts of the same song and play them back together. Each part can play a different sound and, when done recording, you can even play along using a different sound

When you record over a previously-recorded part, the existing data will be overwritten and lost. Before you record, make sure that it is OK to lose the existing data.
Note
The recorded data will be preserved even when you turn off the power.
1. Recording your performance To record your performance
- Press a sound selector switch to select the sound you will use for recording the first part.

- Press the Record switch.
The Record switch indicator will light.

- Look at the Part 1 and Part 2 switch indicators to see the recorded status of each part.
If a part has already been recorded, its indicator will be lit green. If the indicator for a part is blinking green, then it contains recorded data, but its playback will be muted when the recorder is running.
- Select the part that you want to record, and press its switch to make the indicator blink red.
Red blinking indicates that the part is in record-ready mode.
Note
If you press the switch repeatedly, the switch indicator will cycle through the following states.
A part with no recorded data A part containing recorded data

A["Dark (no data)"] --> B["Blinking red (record-ready)"]
B --> C["Press"]
D["Lit green (data exists)"] --> E["Blinking green (muted)"]
E --> F["Press"]
G["Blinking red (record-ready)"] --> H["Press"]

It is not possible to put both parts in record-ready mode at the same time. If one part is set to record-ready, and the other part already contains data, pressing the switch for the recorded part will alternate between the playback and mute modes.
ex: Part 1 contains recorded data, and part 2 is in record-ready status

E --> G["PART 2"]
F --> H["Blinking green (muted)"]
G --> I["Blinking red (record-ready)"]
- Press either the Start/Stop switch, the keyboard, or a pedal.
If you press the Start/Stop switch, recording will begin after a two-measure count. If you press the keyboard or a pedal, recording will begin immediately.
Recording will also begin if a MIDI message is received on the MIDI channel that matches the part you selected in step 4 (p.19).

During recording, the Start/Stop switch indicator will blink in time with the time signature, red on the first beat and green on other beats.
If you use the sound selector switches to change sounds during recording, these sound selections will be recorded as part of the data. During playback, the same sound selections will change automatically.

Data for changes in the pedal settings (©p.13 "Pedal settings for the Layer and Split functions") cannot be recorded.
Note
You can record at an accurate tempo while listening to the metronome (Cp.13).
- When you have finished recording, press the Start/Stop switch.
The recorder will automatically return to the first measure.
Note
You can pause recording by pressing the Pause switch while recording (the Pause switch indicator will light).
To resume recording, first press the Record switch. Then press the switch for the part you are recording twice to return that part to the record-ready mode.
If you press the Start/Stop switch or the Pause switch while in record-ready mode, you will hear a two-measure count and then recording will start from the beginning of the measure at which you paused.
If you play the keyboard while in record-ready mode, recording will start from the paused location without a count.
When you resume recording after pausing, the transition may not always be recorded smoothly. When using this function, we recommend that you use the metronome while you record, and pause on the beat that the last recorded note ends. When you resume recording, you will start from the beat at which you stopped.
2. Listening to a song you recorded To play back a song you recorded
1. Look at the Part 1 and Part 2 switch indicators to see the recorded status of each part.
If a part has already been recorded, its indicator will be lit green. If you do not wish to hear one of the recorded parts during playback, press its switch to make the indicator blink green.
2. Press the Start/Stop switch to begin playback.
During playback, the Start/Stop switch indicator will blink according to the time signature, red on the first beat and green on the other beats.
You can use the Tempo slider etc. to adjust the playback tempo (p.13).
3. To stop playback, press the Start/Stop switch.
Playback will end, and you will automatically return to the first measure.
Note
During playback, you can press the Pause switch (the Pause switch indicator will light) to pause playback.
To resume playback, press the Start/Stop switch or the Pause switch.
When all of the recorded data has finished playing, playback will stop automatically and the Start/Stop switch indicator will go dark.
To adjust the volume balance of the two parts
Note
The C-6500 can remember this setting even when the power is turned off.
- If parts 1 and 2 are playing simultaneously, hold down the Brilliance switch and repeatedly press the switch (either Part 1 or Part 2) for the part that you want to make louder.
To return to the original setting, hold down the Brilliance switch and press the Part 1 and Part 2 switches simultaneously.
To play back your performance in a loop
You can make the entire recorded song play back repeatedly.
- During playback, press the Transpose/Function switch.
The Transpose/Function switch indicator will blink, and the playback will repeat. To stop playback, press the Start/Stop switch. The repeat setting will also be cancelled at this time.
3. Erasing parts
To erase a recorded part.
1. With playback stopped, hold down the Transpose/Function switch and press the switch of the part you wish to erase.
The indicators of the Transpose/Function switch and the switch whose part you pressed will blink alternately red and green, indicating that you are ready to erase that part.

If you decide to not erase the part, press the Transpose/Function switch again to cancel.
2. Once again, press the part switch that you pressed in step 1, its performance data will be erased.

To check the amount of data that has been recorded
- Simultaneously hold down the Transpose/Function switch and Start/Stop switch.

The amount of performance data that has been recorded will be shown by the number of sound selector indicators that are lit. If a larger amount of data has been recorded, more of the indicators will be lit.

During recording, the Record switch indicator will blink if the amount of available memory decreases to 10% of the total memory.
10% or less means that 1,400 or fewer remaining notes can be recorded, or that 900 measures have been recorded (a maximum of 999 measures can be recorded).
Note
If you want to save your recorded performance, we recommend that you save it using a computer or a commercially-available MIDI data filer.

Connecting to other devices
1. Connections with a synthesizer, or audio system
You can connect a synthesizer or audio system to the C-6500, and play their sounds through the speakers of the C-6500, or record your performances on a tape recorder.
INPUT jacks (L/MONO, R)
These jacks allow you to play the output of another device - such as a synthesizer or audio system - through the C-6500's built-in speakers. To adjust the volume, use the volume control of the connected instrument or audio device.
OUTPUT jacks (L/MONO, R)
These jacks will allow you to play the C-6500 through an audio system for performing at higher volumes, or to record your performances on a tape recorder or other audio recording device.

2. Connections with MIDI devices What is MIDI?
MIDI (Musical Instrument Digital Interface) is a world-wide standard that allows various types of performance-related data to be exchanged between electronic musical equipment and computers.
MIDI lets you use the keyboard of the C-6500 to play another MIDI-connected instrument. Sound selections, pedal operations, etc. will also be controlled.
Alternatively, you can use another MIDI keyboard or sequencer (automatic playback device) to control the C-6500 and play its internal sound generator. By using multiple MIDI devices together, you can enjoy even more varied ensembles. You can also use MIDI to save data that you have recorded on the C-6500's recorder.
This section of the manual explains various ways in which you can use MIDI with the C-6500. If you would like to learn more about MIDI, you can read one of the many books available that explain MIDI in an easy to understand way.
MIDI connections
Commercially-available MIDI cables are used to transfer MIDI data. Connect these cables between the MIDI connectors of the C-6500 and the MIDI connectors of the other MIDI device. The C-6500 has two types of MIDI connector.
MIDI IN connector
This connector receives MIDI data.
It lets you use an external MIDI device (MIDI keyboard or sequencer) to play the sounds in the C-6500. Use a MIDI cable to connect the C-6500's MIDI IN connector to the MIDI OUT connector of the external MIDI device.
MIDI OUT connector
This connector transmits MIDI data.
The MIDI messages transmitted from this connector when you play the C-6500 can be used to control an external MIDI device. Use a MIDI cable to connect the C-6500's MIDI OUT connector to the MIDI IN connector of the external MIDI device.

MIDI channels
When you have finished making connections, set the C-6500 to the same MIDI channel as the connected MIDI device. There are sixteen MIDI channels, numbered 1–16. When the C-6500 is first turned on, part 1 will automatically be set to channel 1, and part 2 will be set to channel 2.
- To set the channel for part 1, hold down the Transpose/Function switch and press the key in the range of C2-D#3 that corresponds to the desired channel.

When you set the MIDI channel for part 1, part 2 will automatically be set to the next higher MIDI channel (i.e., one more than the MIDI channel of part 1). However if you set the part 1 MIDI channel to 16, the part 2 MIDI channel will be set to channel 1.
Using the C-6500 as a multi-timbral tone generator
The C-6500 can function as a 16-part multi-timbral tone generator that can be controlled and played from an external MIDI device.
- Use a MIDI cable to connect the MIDI IN of the C-6500 to the MIDI OUT of your sequencer (or similar device).
- Transmit MIDI data from the connected sequencer (or similar device).
For details on how to transmit data from a connected sequencer, refer to the owner's manual for that device.
The C-6500 can be set to receive program change messages along with the performance data. Reception of program changes and control changes can be disabled independently for each MIDI channel 1–16 (see “Program changes”, below)

When using the C-6500 as a multi-timbral tone generator, the sound that is selected from the C-6500's panel cannot be played by incoming data on the specified MIDI channel.
Local On/Off setting
The C-6500 provides a Local On/Off setting. You should use the Local Off setting when you want to play the C-6500's keyboard without sounding its internal tone generator, in order to play only an external tone generator connected via MIDI. You should also use this setting when using the C-6500 and an external sequencer. This will prevent notes from being double triggered (MIDI Echo).
Normally, you will leave the Local setting On so that the C-6500's internal sounds will be heard when you play the keyboard.
When the C-6500 is first turned on, the Local setting will be On.
- Hold down the Transpose/Function switch and press the Piano 1/L sound selector switch.
The Local setting will alternate between On and Off each time you press the switch.
| Local On Piano 1/L switch indicator is lit |
| Local Off Piano 1/L switch indicator is dark |
Program changes
Program numbers on a connected external MIDI device can be selected from the C-6500, or program numbers of the C-6500 can be selected from a connected MIDI device.
Transmitting program changes
Program numbers on a connected external MIDI device can be selected from the C-6500.
- When you use the sound selector switches to select a sound, a MIDI program change number (0–99) will be transmitted as shown in the table.
Receiving program changes
When a program change is received from an external device, sounds of the C-6500 will change as shown in the following table.
The C-6500 will switch sounds when it receives a MIDI program change number in the range of 0–99. The C-6500 will not respond to program change numbers higher than 99.

Control Change Disable can be set independently for each MIDI channel 1–16. For example if you set the MIDI channel to 1 and then set Control Change to Disable, the Disable setting for channel 1 will be remembered even if you then change the MIDI channel to 2.

Control changes from an external device will always affect both sounds of the Layer or Split functions, regardless of the pedal settings of the C-6500 ( .13 “Pedal settings for the Layer and Split functions”).
Synchronizing an external sequencer
An external MIDI sequencer or rhythm machine can be synchronized to the C-6500's recorder.
Since the C-6500 functions as the “master” device (the controlling device), the connected sequencer (or similar device) will be the “slave” device (the device that is controlled).
-
Use a MIDI cable to connect the MIDI OUT of the C-6500 to the MIDI IN of your sequencer.
-
Set the connected sequencer so that it will function as a slave device.
For details on how to make MIDI clock settings etc. on the connected device, refer to the owner's manual of that device.
- Press the Start/Stop switch of the C-6500 to begin synchronized playback.
The C-6500 will transmit MIDI Clock messages (messages used to synchronize the tempo) based on the tempo that you set on the C-6500.
Saving recorder data (Data Dump)
Performance data recorded on the C-6500's recorder can be saved on an external MIDI data filer (storage device), and then reloaded back into the C-6500's recorder for playback when necessary.

Carefully read the owner's manual for your data filer so that you do not accidentally erase important data.
To save performance data to a data filer
-
Use a MIDI cable to connect the C-6500's MIDI OUT to the MIDI IN of your data filer.
-
Operate your data filer to make it ready to receive MIDI data from the C-6500.
-
Hold down the C-6500's Transpose/Function switch and press the E.Piano 1 sound selector switch.
The indicators of the Transpose/Function switch and E.Piano 1 switch will blink, and the C-6500 will be ready to transmit the data dump.
If you decide to cancel without transmitting the data, press the C-6500's Transpose/Function switch.
- Press the Start/Stop switch.
The data dump will begin, and the performance data will be transmitted to your data filer. While transmission is occurring, the Start/Stop switch indicator will blink.
When transmission is completed, the Start/Stop switch indicator will go dark, and the C-6500 will return to its normal condition.

The C-6500 will not produce sound while it is ready to transmit a data dump, nor while it is transmitting performance data to the data filer. The C-6500 will return to its normal operating condition when data transmission ends and the data has been stored in the data filer.
To load performance data from a data filer back to the C-6500's recorder
-
Use a MIDI cable to connect the MIDI IN of the C-6500 to the MIDI OUT of your data filer.
-
Hold down the C-6500's Transpose/Function screen and press the E.Piano 1 sound selector switch.
The indicators of the Transpose/Function switch and E.Piano 1 switch will blink, and the C-6500 will wait to receive a data dump.
If you decide to cancel the operation at this point, press the C-6500's Transpose/Function switch.
- Set your data filer to transmit the saved C-6500 performance data. For details on how to do this, refer to the owner's manual of your data filer.
The C-6500 will receive the performance data. The Record switch indicator will blink while the data is being received.
When the performance data has been completely received, the Record switch indicator will go dark, and the C-6500 will return to its normal state.

The C-6500 will not produce sound while it is receiving performance data from the data filer. The C-6500 will return to its normal operating condition when data reception ends and the data has been loaded back into the internal recorder.
Troubleshooting
Power does not turn on
- Is the power cable connected to the C-6500?
- Is the power cable connected to an appropriate AC outlet?
- Is the power switch turned on? (p.7)
- Did you verify that the outlet is working? (Plug a device known to be working into the same outlet.)
- If the power still does not turn on, unplug the power cable from the AC outlet, and contact the distributor for your country.
No sound
- The C-6500's Volume slider may be set to "0". (Cp.7)
• A plug may be inserted in the headphone jack. - Have you made settings so that the selected part will play back? (p.18)
- Has performance data been recorded for the selected part? (€p.18)
• Make sure that the Local setting is turned On. (p.20)
Notes are interrupted
- You have exceeded the maximum polyphony. If you exceed the maximum polyphony, the C-6500 will turn off a currently-sounding note and give priority to the last-played note. This means that a currently-sounding note will be interrupted.
For sounds other than Piano 1 and Piano 2, the maximum polyphony is 64 notes. However, Piano 1 and Piano 2 use two notes of data, meaning that the maximum polyphony will be 32 notes.
When using the damper pedal, when using the Layer function to play two sounds together, or when playing back recorded data using multiple sounds, you should keep the maximum polyphony in mind as you select sounds.
Something is wrong with the pitch or tone of a piano sound in a specific range
- The piano sounds of the C-6500 re-create the sound of a piano as faithfully as possible. This may mean that certain overtones may appear to be louder in some ranges, or you may notice differences between different pitches or ranges. This is not a malfunction.
Pedal functions do not work correctly
- Is the pedal connector plugged in correctly? (p.26)
- If the pedal effect does not work when using Layer or Split, make the settings once again. (€p.13)
Can't record
- Is there enough free space in the recorder? (p.18)
External device does not respond to the transmitted MIDI data
- Make sure that the MIDI cable is connected correctly. (19p.19)
- Make sure that the C-6500 is transmitting MIDI data on the same channel as selected on the receiving device. (Cp.19)

Place the piano on the stand so that the plastic feet on the bottom of the piano enter the holes in the metal brackets of the side panel. Then use the wing knob bolts to fasten the piano from below.

Get another person to help you place the piano on the stand, and set it down slowly and carefully so that you do not pinch your hand or drop the piano.

- Loosen the adjuster located below the pedals until it firmly contacts the floor.

If the adjuster does not contact the floor firmly, the pedals may wobble, causing malfunctions.

- Connect the pedal cable and power cable to the bottom panel of the panel, and use the cable holders to fasten the cables.

Pay attention to the orientation of the connectors when you plug them in.

Check after assembly
- Are any parts left over?
If any parts are left over, check them against the assembly procedure to determine where they should be used, and reassemble the stand correctly. - Make sure that all screws are correct, and that they are tight.
Other cautions
After you have assembled the stand, please observe the following cautions.
- Loosened screws
After the stand has been assembled, screws may loosen as time passes. We recommend that you regularly check for screws that have become loose. If you feel that the stand has become unsteady, screws may be loose. Please retighten the screws. - Transport Remove the digital piano from the stand, and use two people to carry it separately from the stand. At the new location, reassemble the piano and stand as described in "Assembly procedure."
- Disassembly If you need to disassemble the stand, do so in the reverse order of assembly. After disassembly, keep all screws and other parts together so that they don't get lost.
