Tuning procedure
Meter mode
In this mode the VU style meter shown in the display is used to tune your
instrument.
- If an instrument equipped with a pickup or the optional Korg CM-200 contact microphone is used, connect the instrument or mic cord (plug) to the INPUT jack of the CA-2. If you wish to tune your instrument using the built-in mic, do not connect a plug to the INPUT jack. In steps 4 and 5, place your instrument as close as possible to the built-in mic. If a plug is connected to the INPUT jack, the built-in mic cannot be used. The INPUT jack is for mono use only. Stereo plugs cannot be used.
- Press the power button to turn on the CA-2. When the CA-2 is turned on, the previously specified reference pitch is indicated. When the power is on for 20 minutes without use, the tuner will automatically turn off to conserve battery life.
- If you wish to change the reference pitch (calibration), press the CALIB or button. This can be adjusted in 1 Hz steps over a range of 410 Hz-480 Hz.(*)
- Play a single note on your instrument, and the name of the nearest note will appear in the display. Tune your instrument so that the correct note name is shown in the display.
- Tune your instrument so that the VU style meter moves to the position (center) and the center pitch guide LED is lit.
The left indicator of the tuning guide will light if your instrument is flat, and the right indicator will light if your instrument is sharp. If you want to tune a pure major third above or a pure minor third above a certain note, make the meter indicate “ “ (-13.7 cents) or “ “ (+15.6 cents).
For example if you want to tune a major third above the A (0 cents) note, set the note name display to C#, and make the meter indicate “ “.
Or if you want to tune a minor third above A (0cent), set the note name display to C, and make the meter indicate “ “. While tuning with the built-in mic a quiet environment is recommended for precise tuning. Even if the pitch is within the range of detection, it may not be possible to detect the pitch of an instrumental sound that contains large numbers of overtones or a sound that has a rapid decay.
Sound Out mode
In this mode you can tune while listening to a reference tone.
- Follow steps 2-3 outlined in “Meter mode.“
- Press the (Sound Out) button to enter Sound Out mode.
- Press the (Sound Out) button to select the note name you want to tune. Hold down the (Sound Out) button for about one second to switch selection of the reference tone between the following two patterns*. With AB♭, A or B♭ can be selected. With 12NOTES, any of the note names can be selected. After switching the selection pattern for the reference tone, press the (Sound Out) button to select the note to be tuned to. AB♭ : A → B♭ → Meter mode (default setting) 12NOTES : C(4) → C♯ → D → E♭ → E → F → F♯ → G → G♯ → A → B♭ → B → C(5) → Meter mode
- Tune your instrument to the reference tone that is output by the CA-2.
