Emu XL-7 & MP-7 User's Group

It seems that there's either an error in the files, or I'm doing something very wrong. If I reboot the XL-7, it appears to load the patches up until patch 37 (I'm downloading bank 0), then the 'Sysex: too fast' message appears. Apparently this makes the XL-7 confused, because afterwards all patch downloads are met with the 'Sysex: too fast' message.

Furthermore, the patches don't seem to be correct in that the Sample number is set to 0 = NONE for at least the few that I've tried. 

Strange, I've got a Composer ROM in my XL-7 which I extracted from a P2000, so it should be the correct ROM for these patches. Or have I misunderstood what the patch files are for?
