Doubling:
This effect sets up a tiny time deviation (or delay) between the
left and right sides of a signal to give the sound a stereo feel.
You cannot use the loop effects while the Mastering Tool
Kit is being used.
● Vocal Tool Box (p. 131)
The Vocal Tool Box is used with the playback from tracks on
which solo vocal performances have been recorded, and it
allows you to correct variations in pitch and to add a backing
chorus.
The following two effects can be selected from the Vocal Tool
Box.
Pitch Correction
The pitch correction function allows you to correct the
pitches of vocal performances recorded on a track in real
time and in units of semitones.
Harmony Sequence
This effect adds a backing chorus to the playback of a vocal
performance recorded on a track based on the chord
sequence specified for your rhythm arrangement (p. 156).
If this effect is applied to a track not containing a solo
vocal performance, it will not be possible to achieve the
desired result.
● Mastering Tool Kit (p. 146)
The BR-1200CD's Mastering Tool Kit is used during the
creation of an audio CD to improve the quality of the
finished songs by balancing volumes and compression levels.
When commercially available CDs are originally created,
data is written to them in such a way that the loudest point in
each song is close to the maximum volume that can be
recorded on the CD. A good balance among the volumes of
different performances is the most important factor in
allowing data to be written in this way. However, a special
process known as Mastering is generally carried out to adjust
the overall volume. The Mastering Tool Kit provided in the
BR-1200CD allows you carry out this special processing
simply and quickly.
A good balance of the volumes of different performances is
the most important factor when creating audio CDs that
sound loud and powerful. If performances have not been
mixed and balanced well, no amount of processing using
the Mastering Tool Kit will produce the desired effect.
Makeup of BR-1200CD effects
● Speaker Modeling (p. 142)
This effect allows the acoustical characteristics of various
types of monitor speakers to be modeled for playback.
In professional recording studios, recorded audio is played
through various types and sizes of monitor speakers so that
the sound from each can be compared, and this ensures that
the final mix-down will sound good on any type of speaker.
Even if you only use one set of monitor speakers with the BR-
1200CD, the Speaker Modeling effect allows you to compare
the sound of different speakers in the same way.
Supported combinations of effects
Of the insert effects, the Vocal Tool Box, the Mastering
Tool Box, Speaker Modeling, and the track compressors
only one of them can be used at a time.
