Boss Audio Systems BR-900CD Using the Rhythm, About the Patterns, About the Arrangements

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.

Music patterns to be placed at the ending of a song.
