Frequently Asked Questions - TM-70T KORG

How to change the reference pitch (calibration)?

In tuner mode, use the ▲ and ▼ buttons of the PITCH·A= button to adjust the A4 pitch from 410 to 480 Hz in 1 Hz steps. Long press allows continuous change. This setting is stored in memory.

How to use the metronome with tap tempo?

Press the TAP button several times at regular intervals. The metronome detects the tempo and adjusts accordingly. If the detected tempo is below 30 bpm, 'Lo' is displayed and the value 30 is adopted; if above 252 bpm, 'Hi' is displayed and 252 is adopted.

How to tune in Sound mode?

Activate the tuner then press the ◌ (Sound) button. A reference note is emitted. Use ▲ and ▼ of the PITCH·A= button to select the desired note. Tune your instrument by ear. To deactivate, press ◌ again.

What is Sound Back mode and how to use it?

Sound Back mode produces the reference note closest to the note played. Activate it by long-pressing the ◌ button in tuner mode. Connect a contact microphone or use the built-in mic. The corresponding note is output in the headphone. To exit, press ◌ again.

How to use the Transposition function?

Press the TRANSPOSE button to select the reference pitch (F, B♭, E♭, C). The displayed note changes according to the chosen transposition. Tune your instrument so that the needle is centered.

How to set the time signature on the metronome?

In metronome mode, use the ▲ and ▼ buttons of the 4/4·♪ button to select the number of beats (0 to 9) or special rhythmic figures (duplets, triplets, quadruplets). The screen indicates the time signature.

How to use the tuner and metronome simultaneously?

Press both the TUNER button and the B (metronome) button. The display splits to show both information. Note that some special time signatures are not available in simultaneous mode.

How to change the backlight mode?

Each press of the ® button cycles through modes: Low (permanently dim), Auto (brightens with sound or press then dims after 10s), and Off. The corresponding icon appears.

What to do if the device does not turn on?

Check the battery orientation. If the problem persists, remove the batteries, wait a few seconds, and reinsert them. Make sure the batteries are not exhausted. The low battery icon indicates they need to be replaced soon.

How to connect a contact microphone?

Connect the contact microphone (e.g. Korg CM-400) to the input jack ♀ (3.5 mm mono mini-jack). If no microphone is connected, the tuner uses the built-in mic. Note that the TM-70T does not include the CM-400 (except the TM-70C).

1. To change the reference pitch (calibration), press ▲ and ▼ on the PITCH·A= button.

Each time you press the button, the reference pitch goes up or down in steps of 1 Hz.

Long-press the button to continuously change the reference pitch.

This setting is stored in memory even when you turn off the power.

1. Play a single note on your instrument.

The pitch (note name) that's closest to the note you played is shown at the center of the display.

Tune your instrument to somewhere around the correct pitch, so that the desired note name appears.

If you're using the built-in mic, place your instrument as close as possible to the mic so that unwanted sound is not picked up while tuning.

1. While playing a single note on your instrument, tune

it so that the meter lines up with the ▼ indication at the center, and the LED at the center of the tuning guide lights up.

The left tuning guide LED lights up if the pitch of your instrument is flat, and the right tuning guide LED lights up the pitch is sharp.

Tuning to a just major third above

If you want to tune to a just major third (C#) above A (0 cents), tune your instrument so that the meter lines up with the ▼ on the left side.

Tuning to a just minor third above

If you want to tune to a just minor third (C) above A (0 cents), tune your instrument so that the meter lines up with the ▶ on the right side.

Tuning to a reference tone (Sound Out)

Use the Sound Out feature on this device to tune while hearing the sound that's output.

1. Press the button while the tuner is on. A reference tone is output from the headphones or speaker.

The Sound-Back feature outputs the reference tone that's closest to the tone you're playing on your instrument (the input tone).

This is handy when you want to check whether the note you're playing is out of tune with the reference pitch and in other situations.

You can use this when either or both of the ♀ and ⏰ jacks are being used.

1. Long-press the button while the tuner is on.

appears on the display.

1. Input your instrument's sound via a contact mic plugged into the ♀ jack, or via the built-in mic.
