Tuning an instrument (Tuner)
The BR-864 has a built-in “chromatic tuner function” that
allows you to tune your instrument quickly.
The built-in tuner supports both guitar and bass guitar.
As an example here, we will explain how to use the tuner to
tune your guitar.
* It is not possible to play back or record while using the tuner.
Check the following points before you begin.
• That your guitar is connected to the GUITAR/BASS
INPUT jack.
• That [GUITAR/BASS] indicator on the INPUT SELECT
button is lit.
• That GUITAR/BASS INPUT SENS is properly adjusted
(refer to “Adjusting the input sensitivity” (p. 32)).
If [GUITAR/BASS] indicator is off, press [GUITAR/BASS] to
turn it on.
Changing to the tuner
1. Press [TUNER]
to access the Tuner screen.
fig.05-201d
2. To exit the tuner, press [TUNER] once again (or press
[EXIT]) to return to the Play screen.
If you do not want to output the tuning sounds, either
turn down the MASTER fader.
* You cannot switch from the Tuner screen to other screens
(except the Play screen).
Explanation of the indications
that appear while tuning
When the built-in tuner of the BR-864 is used, the reference
pitch is shown in the upper left of the display, and the note
name in the right. The lower part will display a tuning guide
to indicate the difference between the input sound and the
displayed note.
fig.05-202d
If the difference between the input pitch and the correct pitch
is less than +/-50 cents, the tuning guide will indicate the
amount of the difference.
Watch the tuning guide, Watch the tuning guide as you tune
the instrument so that the vertical line is shown at the ▼
