• Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
• This unit is equipped with a protection circuit. A brief interval (a few seconds) after turning the unit on is required before it will operate normally.

Using the DoReMi Sheet

By affixing the included DoReMi sheet to the pitch indicator, you can use the DoReMi indications to check the names of the notes.

If you want to check the names of the notes when using movable "Do" solfege, affix the DoReMi sheet with "Do" positioned at the note name of the tonic you're using.

DoReMi sheet

• Before using the DoReMi sheet, be sure to remove the backing paper and the blue protective sheet.

Tips for Using the VT-12

Hold the VT-12 in your hand and sing in the posture shown by the illustration.

Use headphones if you want to check the accuracy of your pitch while playing a track or the metronome.

Using headphones will make pitch detection more accurate. It will also make it easier for you to hear the recorded sound.

MEMO

Should you encounter any of the situations described below, check the setting of the [MIC VOLUME] switch (p. 6).

• Pitch indicator is unresponsive, or does not respond as it should.
• Volume of sound from the microphone is low.

Using the Stand

You can use the stand to keep the VT-12 upright.

When using the VT-12 with a group, the stand provides a convenient way to place the VT-12 upright on a desk or table.

When doing so, you should keep the VT-12 about 1m (40 inches) away from the singers.

• To return the stand to its original position, fold it inward until it clicks into position.

You'll probably want to begin by checking your pitch.

The VT-12 is able to check the pitch of not just one, but two voices simultaneously.

This makes it convenient for checking the pitch of two people singing harmony.

1 Select the type of pitch detection.

MONO EQUAL: One voice will be detected using equal temperament.

CHORD EQUAL: Two voices will be detected using equal temperament.

CHORD JUST: Two voices will be detected using just intonation (major).

MEMO

The key for just intonation is determined by the lower pitch.

If the VT-12 is sounding a guide tone, the key is determined by the guide tone. If a guide tone is being sounded, only one voice can be detected.

Press the button.

Before you start vocalizing, sound the guide tone (equal tempered) to hear the correct pitch.

MEMO

You can use the [b] button and [#] button to change the guide tone.

3 Vocalize, and check your pitch.

Vocalize the pitch that you intend to match.

The note name that is closest to the detected pitch will light.

Gets brighter as the discrepancy in pitch grows smaller; gets dimmer if the pitch discrepancy increases.

If a guide tone is sounding, the note name of the guide tone will also light.

• If the pitch indicator does not respond even when you are vocalizing, check the setting of the [MIC VOLUME] switch (p. 6).

Indicates the amount of pitch discrepancy. Lit: ▲Unlit: △
MONO EQUAL	Pitch is flat	b ▲ △#
	Pitch is correct	b ▲ △#
	Pitch is sharp	b ▲ △#
CHORD EQUAL	The high note is flat relative to the low note	b ▲ △#
CHORD JUST	The pitch interval between the two notes is correct	b ▲ △#
	The high note is sharp relative to the low note	b ▲ △#

Changing the reference pitch

1. Press the [b] button and [#] button simultaneously.

The display will indicate the current reference pitch.

1. Use the [][] buttons to specify the desired reference pitch.

Range: 415-465 Hz (default value: 440 Hz)

• If you do nothing for a predetermined amount of time, the indication of the reference pitch will disappear, and the unit will automatically return to the pitch checking mode.

• Press the [b] button and [#] button simultaneously.

The indication of the reference pitch will disappear, and the unit will automatically return to the pitch checking mode.

• During the playback of Preset tracks, the reference pitch is fixed at 440 Hz.

What is just intonation?

Just intonation is a method of tuning that ensures pure fifth and third intervals.

If you select just intonation, you'll need to specify the tonic (for a major scale this will be C) that's appropriate for the key of your song.

The VT-12 will assign the lower of two voices as the tonic.

If a guide tone is sounding, the guide tone will be the tonic.

About pitches in just intonation

The VT-12 can detect just intonation pitches only in a major key.

If the guide tone is C, the pitches are calculated using the following ratios.

	CC#	DD#EF
Equal temperament (cent) 0	100200300	400500
Just intonation (cent) 07120	4316386	498

Additional Precautions

• Please be aware that the contents of memory can be irretrievably lost as a result of a malfunction, or the improper operation of the unit.
• Use a reasonable amount of care when using the unit's buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.
• When disconnecting all cables, grasp the connector itself—never pull on the cable. This way you will avoid causing shorts, or damage to the cable's internal elements.
• To avoid disturbing others nearby, try to keep the unit's volume at reasonable levels. You may prefer to use headphones, so you do not need to be concerned about those around you.
• Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.
