I have been able to convert SD1 styles for use on the KETRON X1 (manually). In areas where there was a heavy reliance on 'grooves'/drum track #2 in the SD1, I used the internal grooves of the X1 and saved the result as a pattern. So although the styles may not sound identical especially in the drum2 track, the rest of the arrangement is rather close (using the sounds of the X1.
I am still working on completing these hopefully by the end of next week.
If you can then convert them from the X1 to the PSR series, you are good to go.
Thanks,
AJ
