Hi Jonny,
unfortunately I don't think that's going to happen.

I've had EMC since it came out in the early 90's ( for various keyboards). I did the last big update when they overhauled the program, but I don't think I'd bother again unless the kn6/7 was supported.
KN7 owners might be better off buying the optional style conversion disk available from technote ( it converts styles from the more current range of keyboards)

Unfortunately that's not much help to kn5 owners.

best wishes
Rikki
