Thank you Mr Technicsplayer, yes I remember now changing the hex codes back in the early 1990's at my shop in Tamworth when trying to swap kn styles over to the GN9 organ without much success in the dim and distant past as you said MANY years ago!!!. I have found the codes and now managed to remove the passwords,the Germans offered a vast number of software discs from software houses now no longer trading and it was for these discs I needed to unlock and use with the KN7000 we in the UK missed out with a lack of support from Panasonic UK. Even with the great support of yourself,Phil and Lutz with great books of tips and tricks plus the full know how to do!!
I know Neil offers a fantastic range of styles but Europe still offers a wide range of second-hand software from the KN range of yesterday all usable with the KN6,65 or 7000. keeping the 7 at the forefront and proving how far ahead it was in it's day over a decade ago,how time quickly passes!!!
Regards John.
