Simply put, I used the Korg OT-120 to set the temperament, then used the temperament as the reference for the outlying octaves (see the tutorial for why we don't use an electronic chromatic tuner for the whole piano), with an occasional assist from the OT-120 as described below. I found the Korg OT-120 to have three distinct advantages. Download Korg NO OT120 User Manual. Korg NO OT120: User Manual. Pro tube ix, Quad vi, Ot-120. Please, tick the box below to get your link.

■ Manual meter mode
In this mode you can tune to a note name that you specify.
1. Make the settings described in steps 1–4 of “Preparations for tuning.”
2. Set the [MODE] dial to MANUAL.
3. Press the NOTE [√] or [®] switch to select the note name (C–B) that you
wish to tune. Each time you press the switch, the note name will change in semitone steps. If you press and hold the switch, the note name will change continu- ously.
This setting will be remembered even if you change modes.
4. Play a single note on your instrument, and tune so that the VU style meter
moves to the 0 position (center) and the tuning guide indicators are both lit. The meter will operate when the difference between the specified note and the input pitch is in the range of -500 cents – +500 cents.
■ Auto meter mode
In this mode you can tune any note you input.
1. Make the settings described in steps 1–4 of “Preparations for tuning.”
2. Set the [MODE] dial to AUTO-SLOW, AUTO-MEDIUM, or AUTO-FAST.
AUTO-SLOW
: The VU style meter will respond slowly to the input sound.
AUTO-FAST
: The VU style meter will respond rapidly to the input sound.
AUTO-MEDIUM
: The response will be between that of AUTO-SLOW and
AUTO-FAST.
3. Play a single note on your instrument.
The LCD display will indicate the closest note name and the octave for the pitch that you played. Tune your instrument approximately so that the correct note name is displayed.
4. Tune your instrument so that the VU style meter moves to the 0 position
(center) and the tuning guide indicators are both lit. The meter will indicate the difference between the specified note and the input pitch in the range of -50 cents – +50 cents.
If you use the internal mic of the OT–120 to tune, place your instrument as close as possible to the internal mic so that extraneous sounds are not picked up by the mic.
In some cases, such as when the sound contains numerous overtones, the OT– 120 may have difficulty detecting the pitch. If this occurs, change the volume or octave, and try again.
■ Sound mode
In this mode you can tune to a reference pitch sounded by the OT–120.
1. Make the settings described in steps 1–4 of “Preparations for tuning.”
2. Set the [MODE] dial to SOUND- or SOUND-
.
The setting produces a low-volume reference tone. The
setting
produces a loud reference tone.
3. Press the NOTE [√] or [®] switch to select the note that you wish to tune.
Each time you press the switch, the reference pitch will change in semitone steps over a five octave range of C2–C7. This setting is remembered even if you change modes.
4. Tune your instrument to the reference pitch that is output by the OT–120.
■ Sound Back mode
This mode outputs the reference pitch that is closest to the note you input via the INPUT jack, and displays the difference between your note and the reference pitch in the meter.
1. Make the settings described in steps 1–4 of “Preparations for tuning.”
2. Set the [MODE] dial to SOUND BACK - or SOUND BACK-
.
The setting produces a low-volume reference tone. The
setting
produces a loud reference tone.
3. Play a single note on your instrument.
The reference pitch closest to the note that you played will be sounded, and the note name will be displayed in the LCD. The meter will indicate the difference between the specified note and the input pitch in the range of -50 cents – +50 cents. Tune your instrument approximately so that the correct reference pitch is sounded.
4. Tune your instrument according to the reference pitch and the VU style meter .
Replacing the batteries/Memory function
When the batteries run down, accurate tuning will no longer be possible. When directed by the low battery indicator in the LCD, replace the batteries as soon as possible.
The batteries are also used to maintain the contents of memory when the power is off in order to preserve the reference pitch, TRANS/TEMPERA- MENT setting, and the note name selected in Manual Meter mode or Sound mode (Memory function).
The various settings of the Memory function will be reset when you remove the batteries or when the batteries run down. (If the AC adapter is plugged in and connected to the OT–120, these settings will not be reset.)
You should leave the batteries installed even when using the OT–120 with its AC adapter.
2. Insert two AAA
batteries. Be careful to observe the correct polarity (+, -).
1. Press lightly and slide in the
direction of the arrow to open the lid of the battery case.
3. Close the lid of the battery
case.
Adjustment screw
Adjusting the zero point of the VU style meter
If the OT–120 is jarred while being transported etc., or due to normal aging after extended use, the VU style meter may drift away from the 0 position (center). Please re-adjust the VU style meter to the 0 position so that tuning will be accurate.
1. While holding down the NOTE [√] switch, turn the power switch ON
and verify that the VU style meter points to the 0 position.
2. If it does not point to 0, open the battery case lid as shown in the diagram
for “Replacing the batteries/Memory function,” and use a small Phillips screwdriver (jeweler's screwdriver) to rotate the adjustment screw until the VU style meter points to 0.
3. After completing the adjustment (or if the VU style meter already points
to 0), press any switch to return to normal operation, and close the lid.

Using the stand
By opening the stand located on the back, you can position the OT-120 at a convenient angle.
The VU style meter may drift from the 0 position (center) when the OT–120 is tilted. If this occurs, perform the procedure described in “Adjusting the zero point of the VU style meter” while the unit is tilted, so that the VU style meter points to 0.

Tuning procedure
The OT–120 provides four modes: Manual Meter, Auto Meter (

), Sound, and Sound Back.
■ Preparations for tuning
1. If you are using an instrument with a pickup or contact mic, connect the
INPUT jack of the OT–120 to the cable (plug) from your instrument or mic. If the OUTPUT jack of the OT–120 is connected to an amp, the sound that is input to the INPUT jack will be output without change. Since this may cause noise during your performance, set the power switch of the OT–120 to STANDBY . If you are using the internal mic of the OT–120
, tune without connecting a
plug to the INPUT jack and OUTPUT jack. If a plug is connected to the INPUT jack or OUTPUT jack, the internal mic cannot be used.
The INPUT and OUTPUT jacks are for mono use only. Stereo plugs cannot be used.
2. Turn the power switch to ON or
. (At the
position, the power will be
on and the display will be illuminated.) When the power is on, the last-selected reference pitch (default: A=440 Hz) and the mode last selected by the [MODE] dial will be active.
3. If you wish to change the reference pitch (calibration), press the CALIB
[√] or [®] switch. Each time you press the switch, the reference pitch will change, and will be shown in the display. If you press and hold the switch, the setting will change continuously.
4. If you are tuning a transposing instrument or tuning to a classical scale,
press the [TRANS/TEMPERAMENT] switch. Each time you press the switch, the setting (key, temperament) will change, and will be shown in the display. If you select a key, the characters “TRANS” will blink in the LCD display. If you select a temperament, the setting will blink in the LCD display.
