Main features

Thirty-two Premium Instrument Sounds
Built into the Korg G1/G1 Air Digital Piano are 32 unique instrument sounds—including a total of three distinct European and Japanese concert grand pianos. The G1/G1
Air also allows two sounds be played at once from the keyboard.
Layer Mode : Each key will play two sounds simultaneously.
Split Mod e: One  of three Bass sounds can be assigned to play on the lower half of the keyboard, independent of the upper sound.
Partner Mode : The keyboard can be divided into two playing areas, making it ideal for lessons with student and teacher side-by-side.
Built-in Demo Songs and Etudes
The G1/G1 Air includes a total of 50 pre-recorded performances; the 10 Sound Demo Songs make full use of the onboard sounds, while the 40 Piano Song etudes allow the player to develop their skills by playing along with the entire performance, or with either the right- or left-hand part muted.
Accurate Pedal Features
The G1/G1 Air provides the same three pedal functions found on a grand piano—Damper (sustain); Sostenuto; and Soft (una corda). Both the damper and soft pedals respond to half-pedaling, varying the depth of the effect by how far down the pedal is pressed. Pressing down on the damper pedal also adds realistic damper resonance to the number 1 and 2 sounds of the G.PIANO, A.PIANO and J.PIANO button..
Digital Metronome
Perfect for rhythm training, the built-in metronome offers a user- variable tempo, volume, and time signature. Choose a traditional pendulum sound or modern-day digital tone.
Onboard Effects
The G1/G1 Air offers three built-in digital effects—each offering three levels—to enhance the quality of the internal sounds. These effects can emphasize the brightness and clarity of the tone (Bril- liance); simulate the natural ambience of a concert hall (Reverb); and add depth and motion to the sound (Chorus). Adjustable Keyboard Touch  You can hoosec from five different settings to adjust how the sound will respond to your keyboard playing dynamics.
Temperament Selection
In order to create an authentic performance in a wide range of music genres, the G1/G1 Air can be set to one of nine temperaments, including equal temperament, pure temperaments (major and minor), classical temperaments (Kirnberger and Werckmeister), as well as temperaments used with Middle Eastern and Indian folk music. When can acoustic piano sound is selected, the stretched tuning used with traditional pianos is automatically selected.
Play in any Key
The Transpose feature can quickly transpose the G1/G1 Air to play in any usical m key—without changing the player’s fingering. The Master T uning parameter can make fine adjustments in the overall pitch of the instrument.
Onboard Recorder
Integrated into the G1/G1 Air is a powerful two-part recorder. Create, record, and playback a library of multi-part performances that can be recalled at any time.
Dual Headphone Jacks
With two identical headphone jacks, the G1/G1 Air allows two people—parent & child, student & teacher, or friends—to listen and enjoy the sound of the G1/G1 Air simultaneously.
The Right Connections
Your new G1/G1 Air is equipped with a stereo Line Out jack, USB port, plus MIDI IN and MIDI OUT jacks, allowing the G1/G1 Air to connect to an external sound system or recording setup, a computer, or other MIDI enabled devices.
Bluetooth speaker (G1 Air only)
If a device compatible with Bluetooth audio is connected via Bluetooth, the G1 Air can be used as a wireless speaker.

Playing the G1/G1 Air

Playing a single sound (Single Mode) The default sound setting when turning on the G1/G1 Air is the German Concert Piano. By using the Save Parameter settings feature, you can instead have the G1/G1 Air power up with any sound you choose (refer to “Save parameter settings” on page 13).

The # column shows the number of oscillators, or voices, used to create a single note for that sound. (refer to “About maximum polyphony” on page 16.)

Playing the G1/G1 Air while using a single sound such as an acoustic piano is referred to as the Single Mode. The G1/G1 Air can also be played using two sounds in the Split Mode or Layer Mode. For details on the various modes, refer to “Performance Modes” on page 10.
When the G1/G1 Air is turned on, the abbreviation for the Sound name appears in the display.

If the Save Parameter Settings feature was used, the Sound name that appears in the display will be the one that was selected before the G1/G1 Air was turned off (refer to “Save parameter settings” on page 13).

Selecting a piano sound

1. Press the G.PIANO, A.PIANO or J.PIANO button.
   The button that you pressed lights up, and the abbrevia- tion for the Sound name appears in the display.

2. Each PIANO button can access three sounds.
   Each PIANO button can call up a concert grand piano sound, plus two additional piano sounds. For example, to select the Ballad Piano sound, press the A.PIANO button twice. The abbreviation for the selected Sound name will appear in the display. While the sound name appears in the display, the available sounds can be selected by pressing the SELECT  or button.

The selected sound remains the same, even if a dif ferent Sound button is pressed.

Selecting one of the Other Sounds

1. Press the OTHERS button.
   The OTHERS button lights up, and the abbreviation for the Sound name appears in the display.

Your FAVORITE sound assignment will remain even if the G1/G1 Air si turned off, regardless of the setting selected for Save Parameter Settings in the Function Mode.

The default setting for the FAVORITE button is the Stage Electric Piano sound.

Using pedals
The G1/G1 Air includes all three of the pedals found on a concert grand piano. Using the pedals can add expression, control, and sophistication to any performance.

Soft pedal (left)
The Soft pedal slightly reduces the volume and softens the tone. Accurate half-pedaling allows you to control the depth of het effect by how far down the pedal is pressed. (“half-pedaling”).

Sostenuto pedal (center)
This pedal provides a similar effect as the Damper ped- al—allowing notes to continue to sound after the key is released—but the effect only applies to the notes already being held down when the Sostenuto pedal is pressed. New notes played after the Sostenuto pedal has been pressed will not sustain.

Damper pedal (right)
As mentioned above, the Damper pedal allows notes to continue to sound after the key has been released, adding a rich, resonant decay. You can also add the damper resonance to the number 1 and 2 sounds of the G.PIANO, A.PIANO and J.PIANO button. Accurate half-pedaling al- lows you ot control the depth of the effect by how far down the pedal is pressed. (“half-pedaling”).

In Layer Mode (see page 10), you can select which sound(s) will respond to the pedal.
In Split Mode (see page 10), the pedal only affects the sounds in the higher section of the keyboard.
In Partner Mode (see page 11), the Damper effect can be applied independently by both players.

The metronome
The Metronome provides a steady, rhythmic pulse that acts as a convenient practice aid for all levels of musicians.

Specifying the mute volume for parts as well as copying and deleting User Songs can be performed from the Func- tion Mode (starting with the “Song: Delete selected part or entire song” function on page 13).

Performance Modes

Playing two sounds at the same time (Layer Mode)
You can play two sounds at the same time on the keyboard. This is called the Layer Mode. While h olding down the button of a sound to be layered, press a nother sound button. The two selected  sound but- tons light up.

The sounds are labeled layer 1 and layer 2 in the order that their buttons are pressed, and the abbreviation for the Sound name of layer 1 appears in the display.
For example, if the sound from the G.PIANO button is to be layer
1 and the sound from the OTHERS button is to be layer 2 ,oldh down the G.PIANO button, and then press the OTHERS button.
Previously, each Sound Button should have been used in the Single Mode to select the correct sound. For example, to layer the German Concert Piano and Clav sounds, first select “ ” for het  G.PIANO button and “ ” for the OTHERS button. Then press both buttons simultaneously to enter the Layer Mode.

When selecting Layer Mode, the total number of voices that can play at the same time is reduced, depending on the total number of oscillators used per voice by the selected sounds. (refer to “About  aximum polyphony” on page 16.)
Sounds accessed by the same Sound Button cannot be layered. For example, Classic Piano and Pop piano are both a ccessed via the G.PIANO button and thus cannot be layered.

Returning to the Single Mode
To return to Single Mode, press any single Sound Button.

Layer Mode settings
In Layer Mode, adjusting the volume balance between sounds, shifting the octave for each sound, as well as enabling/disabling the damper pedal for each sound can be performed from the Function
Mode (starting with the “Layer Mode: Volume balance” function on page 13).

Using split sounds (Split Mode)
When the SPLIT button is pressed and lights up, you can play a bass sound in the lower section of the keyboard and another sound in the higher section of the keyboard. This is called the Split Mode.
In Split Mode, you can select any split point (key that splits the keyboard) for the high notes and low notes.

These settings will not be saved when the G1/G1 Air is turned off; however, the G1/G1 Air can be set to save these settings (refer to Save “ parameter settings” on page 13).

When Split Mode is selected, the total number of notes that can be played simultaneously is reduced, depending on the total number of oscillators used by the selected sounds. (refer to “About maximum polyphony” on page 16.)

1. Press the SPLIT button.
   The SPLIT button lights up, and the abbreviation for the current bass sound name appears in the display.

2. Press the SPLIT button to access the available Bass Sounds.
   The abbreviation for the bass sound name appears in the display. The s elected sound remains the same, even if a different sound button is pressed.

The # column shows the number of oscillators, or voices, used to create a single note for that sound. (refer to “About maximum polyphony” on page 16.)

Using pedals
In Split Mode, the pedals affect only the right side of the keyboard. They have no effect on the left side of the key- board (bass notes).

Changing the Upper Keyboard Sound
In the Split Mode, changing the sound assigned to the upper part of the keyboard is the same as selecting a new sound in the Single Mode.

Changing the Split Point
To change the dividing point between the upper and lower portions of the keyboard in the Split Mode, simply hold down the SPLIT button and press any key on the keyboard. The split point appears in the display while the button is held down.
The sound range used by the higher section of the keyboard starts with the key to the right of the one that was pressed. The split point remains the same for all three sounds selected with the SPLIT button.

Returning to the Single Mode
To return to Single Mode, press the SPLIT button several times; the button will go dark.

Split Mode Settings
In Split Mode, adjusting the volume balance between sounds and shifting the octave for each sound, can be performed from the Function Mode (starting with the “Split Mode: Volume balance” function on page 13).

Performing with another person (Partner Mode)
Two people can play in the same range with the keyboard divided in half between them. This is called the Partner Mode.

1. While no song is being played back, press the FUNCTION button.
   The FUNCTION button will light.

2. Press the FAVORITE button. “ ” will appear in the display.

3. Press the TEMPO + or – button (at the right side of the display); “ ” appears in the display.

The Partner Mode is turned on, and the selected sound is used for both the left and right sides of the keyboard. When the Partner Mode is turned on, the SPLIT button blinks.
The right side of the keyboard, from E4 to C8, produces sounds two octaves lower in pitch (E2–C6).
The left side of the keyboard, from A0 to E♭ 4, produces sounds two octaves higher in pitch (A2–E♭6).

Different sounds can be selected for the left and right sides of the keyboard.
The sounds for the left side and right side are applied in the order that their buttons are pressed, and the abbreviation for the Sound name of the left side appears in the display. For example, if the sound from the G.PIANO button is to be applied to the left side and the sound from the OTHERS button is to be applied to the right side, hold down the G.PIANO button, and then press the OTHERS button.
Previously, each Sound Button should have been used in the Single Mode to select the correct sound.
To use the same sound for both the left and right sides of the keyboard, press only one sound button.

Damper Pedal Assignments
In the Partner Mode, the Soft pedal acts as a damper pedal for the left side of the keyboard; the Damper pedal acts as the damper pedal for the right side of the keyboard.
The Sostenuto pedal has no function in Partner Mode.

Partner Mode Settings
In Partner Mode, adjusting the volume balance between sounds and shifting the octave can be performed from the Function Mode (starting with the “Partner Mode: Volume balance” function on page 13).

Other functions

connected via Bluetooth audio. It cannot be adjusted with the VOLUME knob on the G1 Air.

The auto power off function of the G1 Air will not oper- ate during playback of a device connected via Blue- tooth audio.
Multiple devices cannot be connected at the same time.

Connecting a New Device (Pairing)
When a new device is connected, “pairing” (mutually registering connection information) must be performed.
The information for up to eight paired devices can be stored. When a ninth device is paired, the information for an existing device is deleted so that the new information can be stored.

Even if pairing failed, the information for that device may be stored on the G1 Air. If the information for eight devices has already been stored, the information for an existing device is deleted.
In order to reconnect to the device whose information was deleted, delete the G1 Air’s information from that device, and then perform pairing again.

1. When the G1 Air is turned on, it enters the pairing standby mode.
   Pairing is enabled for only 1 minute after the abbreviation for the Sound name appears in the display after the G1 Air was turned on.

2. Turn on the Bluetooth function for the device to be  connected to, and then select “KORG G1Air” in thelist of the settings screen that appeared. When a message appears, requesting permission for pairing, allow pairing.
   When a passkey is requested, enter “0000”.
   The passkey may also be called a PIN code, password, etc.

3. If pairing is successful, the connected device enters a connection-ready mode and displays a connection with “KORG G1Air”.

Since the displays differ depending on the device, refer to the manual of your device.

Reconnecting to a paired device

• If the Bluetooth function for the device to be connected to was turned off when the G1 Air was turned on Turn on the Bluetooth function for the device to be connected to.
• If the Bluetooth function for the device to be connected to was turned on when the G1 Air was turned on
  Turn off the Bluetooth function for the device to be con- nected to, and then turn it on again, or select “KORG G1Air” in the list of paired devices.

If a connection cannot be established again, turn off the Bluetooth function for the device, and then turn it on again. If a connection still cannot be established, cancel pairing or delete the  information from the device, and then try performing the operation described above in “Connecting a New Device (Pairing)”.

Cutting the Connection
Perform the operation by using the Bluetooth settings screen on the connected device.

If the 1G Air is turned off while it is connected to a device, it may be difficult for the connection to be re- established the next time.

Appendix

Troubleshooting
If any of the following problems should occur, carefully examine the instrument to see if you can discern what the trouble may be, and try resolving it by following the  suggestions below. If the instrument still does not function  properly, please contact your dealer.

The instrument will not turn on

• Check that the AC adapter is correctly connected to the piano and the outlet.
• Make sure that the power cord is fully plugged into the AC adapter.

No sound

• Is the cord from the speaker box connected securely to the speaker connector on the G1/G1 Air?
• Be sure that the volume is set to an adequate level, and not set to the MIN value.
• Make sure that the MIDI Local function is not set on OFF (see page 13). If it is, set it to ON (or turn the instrument off and then on again).
• Check to see that nothing is connected to the headphone jacks; any connection to either of these jacks will mute the internal speakers.

Notes are interrupted
The maximum polyphony may have been exceeded; see “About maximum polyphony.”

The sound has changed.
Effects such as reverb and chorus are saved with each sound.
The effect settings that are applied differ depending on the order that sounds are selected in Layer Mode or the sounds selected for a User Song; therefore, different nuances may be heard even with the same combination of sounds. Be careful when selecting sounds.

The pitch or tone of the piano sounds wrong in some key regions
The G1/G1 Air’s piano sounds replicate the sound of an actual piano as faithfully as possible. This means that in some regions of the keyboard, you may feel that certain overtones seem stronger, affecting the pitch or tone. This is not a malfunction.

Your external MIDI device does not respond to MIDI data sent from the G1/G1 Air.

• Make sure that all MIDI cables are correctly connected.
• Make sure that the G1/G1 Air is transmitting MIDI data on the same channel that the MIDI device is receiving on.

About maximum polyphony
If the number of notes being played simultaneously exceeds the maximum polyphony, some notes will be lost since the G1/G1 A ir si equipped with a mechanism that stops the first note being played to give priority to notes played with keys pressed later. Some G1/G1 Air sounds, although they may be a single sound, are generated by two or more oscillators (one note of a sound- generating circuit). Sounds using just one oscillator, such as the Electric Grand and Clav sounds of the  OTHERS button, have a maximum polyphony of 120 notes. Sounds using four oscillators, such as the sounds of the G.PIANO button, have a maximum polyphony of 30 notes.
120 ÷ Number of sound oscillators = Maximum polyphony
Keep the maximum polyphony in mind and carefully choose sounds when using Layer Mode to play two sounds simultaneously or when using the damper pedal.

System initialization
The G1/G1 Air can be returned to its factory default condition. All functions in the Function Mode will be returned to their factory default settings, and all recorded data will be deleted.

Deleted data or settings cannot be recovered. Before continuing with this procedure, make sure that you want to delete the data and settings.

1. Turn off the G1/G1 Air.
2.  While holding down the FUNCTION and METRONOME buttons, turn on the G1/G1 Air.
3. After “ ” will appear on the display for about 2 seconds, the normal power is turned on.

Assembling the Stand

Warning

• At least one other person must help you assemble the stand.

Caution during assembly
In order to assemble the stand safely, please observe the following points.

• Make sure that you have the correct part in the correct orientation, and perform the assembly in the order given.

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
  To move the assembled stand, remove the AC adapter cord from the stand, close the key cover, and then move it slowly with at least two people keeping it as level as possible.

• 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.

The G1/G1 Air should always be laid down before disassembled.

Assembly procedure
You’ll need a Phillips (+) screwdriver.

1. Put the protective sheet, which had covered the G1/G1 Air, on a flat floor, and place the G1/G1 Air on that sheet with its rear facing the floor.
   In addition, place cloths or magazines so that you may easily put your hands under the G1/G1 Air when assembling and raising the stand.
   

2. Make sure that all of the following parts are available.
   

3. While adjusting the gaps between the left and right side panels and the G1/G1 Air, fasten them together using four screws (M6)
   If it sifficult id to align the screw holes, place a cloth or magazine under the left and right side panels to adjust their heights.
   

4. Temporarily tighten* the pedal board to the hardware inside the side panels of the stand, using four screws (M4, long).
   Be careful not to scratch the side panels.

• To temporarily tighten the screws is to tighten them leav ing a clearance of about 2 mm.
  

  5. With the help of another person, slowly stand up the stand being assembled.

  6. Lift up the speaker box so that the brackets (A) on the left and right side panels pass through the dents in the speaker box. When the brackets (A) are fully hidden within the speaker box, push the speaker box forward so the rear of the speaker box is nearly flush with the edges of the side panels. Then, the speaker box can be released.
     

  7. Align the bracket holes in the left and right side panels with the holes in the speaker box, and then secure them with the four screws (M4, long) so the gaps on the left
     and right sides are equal.
     At the same time, secure the cord holder with the top screw on the left side panel.
     

  8. Attach the brackets at the holes (under the speaker box) in the left and right side panels with the screws (M4, short).
     

  9. Slightly bend the rear panel and insert it into the grooves in the left and right side panels.
     Be careful not to pinch your fingers.
     

  10. Lift up the rear panel to align the holes in the rear panel and the brackets installed in step 8, and then temporarily fasten the bottom of the rear panel with the four screws (M4, short).
      

  11. Fasten the rear panel and the brackets (through the holes aligned in step 10) with two screws (M4, short).
      

  12. Connect the attached pedal cord, observing the correct orientation, to the connector on the reverse side of the pedal unit, and then engage it with a slot in the pedal unit.
      The pedal cord can be attached to or detached from the connector with its locking tab held down.
      

  13. Lift up either the left or right side of the stand to insert the pedal unit into the pedal board.
      

  14. Insert the pedal unit into the pedal board, and then fasten it by pressing a push rivet into the hole (above the cutout) at the rear of the pedal board.
      After installation, lift the stand to check that the pedal unit does not fall out.
      The push rivet will prevent the pedal unit from falling out. Therefore, it cannot be fully fastened to the pedal board.

  15. Firmly tighten the pedal board and rear panel screws temporarily tightened in steps 4 and 10.
      When tightening the screws on the G1/G1 Air, adjust the up/down and front/rear positions on the left and right side panels so that they are equal.

  16. Make sure to attach the anti-tipping brackets behind both side panels. And the anti-tipping bracket fastened to the left of the code holder at this time.
      Attach the anti-tipping brackets, starting with the round hole at the bottom.
      Joints between the side panels and the attached anti-tip- ping brackets should be even (with no level difference left).
      

  17. Ensure that the stand has no gaps and is not tilted, and that all the screws are tightened firmly.

  18. Connect the AC adapter (refer to “Connecting the Power” on page 5), pedal cord and the speaker cord to the Connector Panel at the center of the underside of the keyboard unit.
      When connecting the pedal cord and the speaker cord, observe the correct orientations of the connectors. The pedal cord or the speaker cord can be detached from the connector with its locking tab held down.
      

  19. Use the two cord holders to secure the AC adapter cord and pedal cord.
      After securing the cord with the cord holder, ensure that excess pressure is not applied to the connectors.

  20. Place the G1/G1 Air where you intend to use it. Make sure to place it in a safe location where the floor is flat and stable.

When setting the digital piano in place, make sure that the stand does not rest on the AC adapter cord or pedal cord.
For greater safety, be sure to attach the anti-tipping brackets 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.
