Picked up a used Eleven Rack and started messing with it. Started playing with all the factory presets and kept scrolling and scrolling. Went through A-Z, then a-z again, came to the end and that was it. Does the Eleven Rack not have a section for you to create your own patches? Do you have to just overwrite the factory presets? Or did the guy I bought it from just fill them all up? OR is there some other mode I have to go into for user presets?
