This automatically plays one of four Fill-in patterns, and smoothly leads into the next section - even if it is the same section. 7. Set the Accompaniment Volume, if you wish. You may want to adjust the accompaniment volume, separate from the overall instrument volume. To do this, use the ACCOMP VOL buttons.

Press the JAM TRACK button during playback, and the accompaniment will continue, changing chords according to the programmed progression, letting you "jam" or play along with the changes. The Jam Track accompaniment pattern depends on the Main A or Main B section that has been selected just before pressing the Jam Track button. Press ACCOMP VOL a to increase the volume and ACCOMP VOLz to decrease it; holding down the appropriate button continuously increases/decreases the volume. The level is shown in the display.

The ACCOMP VOL buttons can not be used during song playback or when the SONG mode is selected. 8.Change the accompaniment ensemble "size" (LARGE/SMALL), if you wish. Press the LARGE/SMALL button. JAM TRACK button JAM indicator in display The JAM indicaton appears in the display, flashing before playback of the pattern and staying lit during playback.

(For example, if you are playing a song in the key of E, play an E chord before pressing JAM TRACK.) ¥If you press the MAIN A or B button, the Fill-in will begin immediately, and the new section will actually begin playing from the top of the next measure, unless the MAIN A or B button is pressed during the last beat of the measure - in which case the Fill-in will begin from the first beat of the next measure. ¥The section buttons can not be used during song playback or when the SONG mode is selected.

You can do this in one of two ways: • Pressing the START/STOP button The rhythm/accompaniment stops playing immediately. • Using an Ending pattern Press the ENDING button (the ENDING indication in the display flashes). An ending pattern plays from the next measure, then playback stops. 7
