The KN2600 interests me because of it being much lighter for gigs than taking the KN7000. I am assuming that the KN2600 is the best keyboard the company made under the KN7000 – right? Can all the work created in the KN7000 that is on SD card be loaded into the KN2600? This would also include any custom memory sounds. Out of curiosity, does the KN2600 take the four expansion boards, as does the KN7000? Finally, what is the REAL difference between the keyboards? Thanks.
