Fixing the Pitch of Vocals (Pitch Correction)
The Pitch Correction
The term Pitch Correction is used to describe a group of effects that are used on recorded vocal tracks to fix incorrect pitches.
When compared with guitars, pianos, and other musical instruments, the human voice generally produces a relatively unstable
tone. And when recording unprepared vocalists, this can often lead to considerable difficulties in the form of notes sung out of
tune and poor sound quality.
When properly used, the BR-900CD’s Pitch Correction will help to ensure that your vocal tracks will always sound great.
Makeup of the Pitch Correction
This effect is intended for use with the playback of recorded audio tracks and cannot be used on input sources.
The Pitch Correction and audio tracks are connected as shown below.

Pitch Correction Patches
In the case of pitch correction, you can set up the way in which the effect is to be applied and can then save these settings. A group
of such settings is referred to as a Patch.
At the time of purchase, a total of 5 pitch correction patches (i.e., preset patches) will be stored in the BR-900CD. In addition, 5
song patches can be set up for use within a specific song.
Precautions for Pitch Correction Usage
• When you are using the Pitch Correction, you will not be able to use insert effects, or the Mastering Tool Kit.
• The Pitch Correction is intended for use with recorded vocal tracks and it cannot be applied to input sources or the Master output.
• These effects will function when applied to solo performances other than vocals; however, the fundamental differences
between the character of the human voice and that of musical instruments makes it highly unlikely that the desired result will
be achieved.
• In the following situations, the Pitch Correction may not be able to accurately detect the pitch, and normal operation will not
be possible.
- When other sounds are mixed in with the solo vocal part.
- When the volume of the vocal part is excessively loud or quiet.
- When the vocal part contains a lot of sibilance or is very breathy (such as a singer that whispers, or one with a husky voice).
- When the vocal part contains an excessive number of different pitches (such as fast, deep vibrato or fast speech)
- When the part is sung with a very low voice containing a lot of harmonics.
* If the BR-900CD is frequently incorrect when detecting the pitch, either change the “Type” setting for the pitch correction function.
In certain cases, this will reduce the number of incorrect detections.
