nice link Dnj, thanks for that!!
Graham, i know exctly what you mean about features that were great but were left out.. one feature i really loved on the PSR8000 was the Virtual Arranger where it added riffs and extra chord changes that really made the style so attractive. I remember especially the PopBallad style with this on, playing "When Will I See You Again" never sounded so lovely, so effective. I was absolutely gutted when it was removed in the 9000, another reason why i left Yamaha, where the PSR8000 being the last Yammy i owned...
