I was impressed by the styles on the Ketron/Solton X1,but after a year realizing they were to busy for my personal taste. They were the most demonstrative to date, also the SD1. I don't care for the Yamaha styles , I like some but most do not suit me. Strangely, I have noticed a difference in the converted styles from the PSR9000 and PSR2000, same name styles,but the 9000 are better[sounds like different voicing]].I also like the VA series[Roland] styles ,thanks in part to "scat"patches used in some of the styles.After all is said and done , it is still the G1000 with the best of all the other manufacturers styles converted to the Roland format.I don't sacrifice the ability to get around and still have what works for me..
