I have loaded SD1 Styles, X1 styles and MS50 styles and they all load and play great. On the old XD9 if you wanted to load SD1 styles you had to go through a process of first taking the styles from the internal memory into the pattern record mode and then going through a copy routine and then saving them onto a floppy before loading them into an XD9, but the SD5 can read any format of Ketron Styles.
I also just found out that the SD5 has a sub woofer inside so this is why I hear such nice tight bass.
