P-Man - I have emailed you already and mentioned this. There are a few of the SD1 styles that load but won't play back (You sometimes get a memory error but usually they wont play back. Once one of these is in user RAM none of the patterns (user styles) will play. Just load the SD1 styles one by one to find the incompatible ones and discard them.

The vast majority of the SD1 styles sound really good on the XD and some of them are amazing.........
