You can select the Main A or B section by pressing the appropriate button —
[MAIN A/B] — before pressing the [START/STOP] button. (The display

Indicates selected section (Main A or B).
I Using Tap Tempo to Start
This useful feature lets you tap out the speed (tempo) of the style and auto-
matically start the style at that tapped speed.
Simply tap the [TEMPO/TAP] button four times (or three times for a 3/4
time style), and the style starts automatically at the tempo you tapped. You
can also change the tempo while the style is playing by tapping the
[TEMPO/TAP] button twice at the desired tempo.
I Using Sync Start
The DGX-500/300 also has a Sync Start function that allows you to start the
style by simply pressing a key on the keyboard. To use Sync Start, first press
the [SYNC START] button (the beat marks all flash to indicate Sync Start
stand-by), then press any key on the keyboard. (When auto accompaniment
is on, play a key or chord in the auto accompaniment area of the keyboard.)
