it's the same on my originals, so it's possible this is how it was on the KN3000. Just change the 1st panel memory to something else you like, change the Conductor from Right 1 to Right 2, resave panel memory 1 and then resave the file for instance, sounds good to me.
As it happens the same rhumba was on the KN5000 under Rhumba Espana with four different registrations.
