Does this happens with styles made for Yamaha keyboards??
This problem occurs (quite often)as far as I know with converted styles from other brand keyboards. The bass doesn't 'walk' with mainly the intro and sometimes the ending, that of course sounds very monotone. Also often the intros and endings sound offkey. My experience with this problem is trying to 'tweak' the styles yourself. But in my case after trying it many disappointing times I deleted most of them. Sorry I can't give a more positive answer to solve this.
Why bother anyway... If you go to psrtutorial.com you can download for free tons of already tweaked styles that will work on your keyboard.

PSR 3000 Auto Accompaniment by: Alfred
Dear Richard: In addition to Dick Rector's comments, are you watching the indications in the unit's Display to ensure the AUTO ACCOMPANIMENT is ON? Sometimes this is overlooked. If there is no Display indication,try the basic Initialization (just turn the unit OFF) and try the Accompanimenet Button again while watching the Display as mentioned. Good luck.
