When you record, it is convenient to use the built-in 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.

By using the Rhythm during recording, you can use the track 
editor to edit in units of measures, synchronize outputs with 
an external device, and perform other useful operations. For 
more details, refer to “Editing the Performance on a Track 
(Track Editing)” (p. 67) and “Synchronizing Playback with a 
MIDI Sequencer” (p. 158). 

You can also change the tempo or Rhythm pattern during a 
song. For more details, refer to “Section 4 Using the Rhythm” 
(p. 119).

The Rhythm features two modes, “Pattern mode” and 
“Arrangement mode.”

You can perform patterns and create your own original 
patterns.

You can perform arrangements and create your own original 
arrangements.

Patterns and arrangements are composed as shown below.

These are drum performance phrases from one to several 
measures in length.

Internal patterns (preset patterns) include prepared patterns 
for intros, verses, fill-ins, and endings.

Patterns arranged in the order they are performed (for 
example, intro, verse, fill-in, and ending) and played at the 
selected tempo comprise a song.

The Rhythm is preset with a wide variety of arrangements,
