I have also been trying to load the styles with exactly the same problems described by others. I must point our that I have recently acquired a KN7000 after a long spell on Tyroses 1 and 2. (Is that the right plural for Tyros?). I did not get anything other than the board and manual so I do not have the Panasonic Song Manager Program which appears to be essential to perform this load.
Is it possible to obtain the disc on which this program appears? I am so pleased to be playing the KN7000 again after the Tyros years but do find some of the built in styles a bit dated and would very much like to be able to load others.
Any advice would be greatly appreciated.
