We are getting different answers from FlutteringBy and Rikkisbears.
So there is only 3 user areas (composer memories) for storing external styles (same as on the Yamaha PSR550). Styles can be loaded from disk on the KN2400 or SD Card on the KN2600, but they would be loaded into the 3 composer areas, and not directly from disk/sd card. Again this is like my PSR550. I can load styles from disk into the 3 user areas. This would make the functionality of a Technics $1800cdn keyboard identical to a $850 keybaord!!!
Am I understanding this correctly?
