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

I just purchased a used XL-7.  It should be arriving early next week.  Can any experienced users give me a check-list run through to check that my instrument is fully functioning?  I read the quick start section in the manual and that should cover a lot of the testing I am looking for, but was wondering if there was any "make sure you check this" type stuff.

Thanks
Bob
