Or why their numbering sequence was so confusing? When the KN3000 was out the mid-size was the KN1500, but the KN5000 had no KN2500. Then the KN6000 came out and the mid-size keyboard was the KN1400 but the KN6500 had no KN3250. With the KN7000, we should expect a KN3500 and get a choice between the KN2400 and the KN2600. I scratched a bald spot on my head with this logic! Now the mystery will never be solved and we all might as well sign up with Bebop for accordion lessons.
