As far as I know, the Yamaha is not yet added
as an option in the "keyboardversion" of the
convert software.
At least the newest models as PSR8 and 9000.
Then EMC Styleworls may be a solution? http://www.emc-musicsoftware.de/

If it is just a style or five, I may be able to
help you Peter, but you have to do the tweaking
to get it sound right at the KN7 yourself, you
know, I still have'nt swapprd my great KN5000
Happy playing.
