Look What You Can Do!
The VT-12 is the ideal tool for improving your vocal skills.
You can use the VT-12 anytime and anywhere—by yourself or in a group, at home or in the studio.
Checking Your Pitch
The VT-12 can detect the pitch not only of a single voice, but also of two voices!
When singing harmony with another person, you can use it to check that
you’re both singing the correct pitches.
As a Metronome
The VT-12 can provide a guide tone to help you keep the correct tempo when
you’re singing alone, or when practicing a cappella or with a vocal group.
2
Vocal Training
The VT-12 provides an eective way to warm up or to practice vocal exercises.
You can use the built-in tracks to practice vocalizing before a choral or live
performance, or use it to polish your vocal technique and expression.
MetronomePracticingChecking Pitch
What are tracks?
The VT-12 contains built-in tracks that you can use when practicing (warming up or
exercising). In addition to the built-in tracks, you can also record your own favorite songs
(p. 14).

Before You Use the VT-12
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.
Use headphones
About 30 cm
(12 inches) away
Keep your back straight
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 1 m (40 inches) away from the singers.
* To return the stand to its original position, fold it inward until it clicks into position.
10
Before you start vocalizing, sound the guide tone (equal tempered) to
hear the correct pitch.
MEMO
You can use the [
] button and [ ] button to change the guide
tone.
Checking the Pitch
Vocalize the pitch that you intend to match.
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.
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.
Select the type of pitch detection.
1
Press the [ ] button.
2
Vocalize, and check your pitch.

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

Checking the Pitch
Changing the reference pitch
1. Press the [ ] button and [ ] button simultaneously.
The display will indicate the current reference pitch.
2. 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.
3. Press the [ ] 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 xed at 440 Hz.
What is just intonation?
Just intonation is a method of tuning that ensures pure fth 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.
C C# D D# E F
Equal temperament (cent) 0 100 200 300 400 500
Just intonation (cent) 0 71 204 316 386 498
