Using fcb 1010 standard, the first patch of bank 00 (switch 1) midi number was 127 (I'm sure it's supposed to be 01?). Following some assigning of other profiles this first patch changed to 120. The following switch 2 is assigned midi 2, then, switch 3 is midi 3 etc.
After assigning a different sound to what is now midi 120 after changing profiles and back the first patch changes back to the profile assigned to 127.
