Using the Rhythm
The “Rhythm” is a dedicated Rhythm track that can not only
play back Rhythm sounds as a guide during recording, you
can also use it to play internal Rhythm patterns and original
user-created Rhythm patterns and to play and record these
patterns as your own Rhythm part performances.
The Rhythm features two modes, “Pattern mode” and
“Arrangement mode.”
Pattern Mode
You can perform patterns and create your own original
patterns.
Arrangement Mode
You can perform arrangements and create your own original
arrangements.
About the Patterns
These are phrases consisting of from one to several measures
of drum performance.
Types of patterns
Preset patterns (P001–P327)
These are internal patterns stored in the BR-900CD that have
already been prepared for use. There are 327 patterns
categorized by musical genre, such as “rock” and “jazz.”
* You cannot change and overwrite Preset pattern data.
Preset patterns include prepared patterns for intros, verses,
fill-ins, and endings (you can confirm the type by looking at
the characters at the end of the pattern name).
(Example)
ROCK1-IN (Intro) ROCK1-V2 (Verse2)
ROCK1-V1 (Verse 1) ROCK1-F2 (Fill 2)
ROCK1-F1 (Fill 1) ROCK1-E (Ending)
“Preset Pattern List” (p. 207)
IN (Intro)
Music patterns to be placed at the beginning of a song.

Music patterns to be used as phrases to connect different
sections of a song. You can select either “1” or “2” depending
on the form that will follow the fill.
