Derek, I assume you know that any panel memories that select the built in Stride Piano rhythm at the KN7000 will have to be changed to select the Composer at the KN2600.
I have also found that almost every style that is moved from the KN7000 to the KN2600 needs editing of the voices used, because the two keyboards handle sound edits differently. But, in the case of the Stride Piano the sounds should be relatively compatible.
