If I have Gaia, and M1, and Mellotron samples in my User 1, 2, and 3, do I rename my recently purchased Espen sample bank u04 before installing? They come with the name u00. Does u00 go into User bank 1, and u01 go into User bank 2, etc? I don't see a User bank 0 on my PX, so I'm guessing the number has a 1 offset? Thanks for any help!
