I have received 3000 files that only have Memory A and Variations 1 and 2. Are there any files that contain all 3 memory banks as well as all 4 Variations? I would think it would be scarey to use one of those files on a gig and you go to memory b or to var 3 or 4 only to find NOTHING is there, cause your board wont play anything. Is this the usual type of file you can get or should I not even bother with incomplete files?
