Ronald,
I have just sent you an email with an indepth factual report on the KN800 and included a zip file of KN800 styles and registrations for you to try out. I can also send you some KN800 songs if you want them but bear in mind the KN800 did not save midi files you could play on other insturments but only allowed you to play Instruments samples in other workstations that we all used at that time.
Hope this helps you out.
