You are all make me feel sorry that I need to amortize my PSR-8000 a little longer. I think when I bought it, it was the only vocalist arranger--so I shouldn't feel too stupid. But it is more trouble than its worth to swap custom styles in and out. In some cases, it will play styles from floppy disks, but there are several limitations. You cannot do it from the HD. Also, my favorite style is an import from an earlier Solton. If I were to buy today, it would be the X1. I will wait and take a closer look at the PSR-9000. I think these keyboards together may open competitor's eyes. (I assume there's really more than a dozen of us interested in these things.)
