Hi there
EMC software is a lot of money but for me it's been worth every penny...not only does it convert KNxxx to KNxxxx but it also converts Yamaha Solton Korg Roland etc etc style files to Technics KN.
In addition it makes a passable attempt at converting Midi files to style files which can be invaluable if only as a reference to lead you to the best standard rhythm.
If there are any KN style files that you particularly want converted send them to me (not millions!) telling me what they are currently and what you want them converted to...
Best wishes
