Tuning an Instrument (Tuner)
The BR-900CD 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 jack.
• That [GUITAR/BASS/MIC2] indicator on the INPUT
SELECT button is lit.
• That GUITAR/BASS INPUT SENS is properly adjusted
(p. 35).
If [GUITAR/BASS/MIC2] indicator is off, press [GUITAR/
BASS/MIC2] to turn it on.
Changing to the Tuner
1. Press [TUNER] to access the Tuner screen.

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-900CD 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.

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.
