Mike, I think you have missed the point
The only reason I will not apply the update is that it has not yet been sanctioned by Technics. I don't know where the upgrades in question originated therefore I will not take the chance of deliberately corrupting my keyboard's firmware. Would you apply an unauthorised, non-manufacturer modification to your top of the range car and take the chance of the engine crashing out in the middle of nowhere ?
I'm happy to wait for the official 'Nod of Approval' from Technics and not worried about being Bang-up-to-date. After all, my KN7000 appears to be working perfectly well.......
