Roland DR-3 用户手册

The DR-3 features two performance modes, Style Play mode, in which the rhythm patterns are 
switched as you play, and Song mode, in which you create data by arranging the patterns 
beforehand, and then perform.
Furthermore, “Style Play mode” features a Manual mode, in which you switch the rhythm 
patterns yourself, and an Auto mode, where the rhythm patterns are switched automatically.

A Style contains a set of rhythm patterns that are needed for performance of a song.
In order to perform a song, you need to have different rhythm patterns set in different parts of 
the song. For example, a rhythm pattern may change like this: Intro/melody A/melody B/
chorus/ending. To express the variation in such a song, each Style includes eight prepared 
rhythm patterns.
The DR-3 includes 100 different Preset Styles (internal Styles) in rock, jazz, and various other 
genres, so you can play all the rhythm patterns for a single song by selecting the genre you want 
to play in and then switching the patterns.
A Song is created by arranging the sequence of rhythm patterns that make up the song. 
You can also create a song by setting up a sequence of patterns from different Styles. What's 
more, you can prepare further song data after you have created a song by editing parts of a song, 
for example by changing bass phrases.

Switch between these three modes with the MODE button shown below.

Switch to Manual mode by pressing the MODE [MANU] button.
In Manual mode, you can switch patterns by pressing the pattern pads. You can perform freely 
as you switch the patterns.

Switch to Auto mode by pressing the MODE [AUTO] button.
In AUTO mode, you can have patterns switch automatically after the performance starts, which 
then lets you enjoy jamming.

When using a MODE button to switch modes, stop the performance first before you press the button.
